Player Avatar

Player and Avatar System in Decentraland

CRITICAL: The player Transform is READ-ONLY from scene code

Transform on engine.PlayerEntity is engine-controlled. Mutations from scene code are silently ignored — your code compiles, runs, no error is thrown, and nothing moves in-world. This is the most common bug when trying to lift, push, knock back, float, or teleport the player.

// WRONG — compiles cleanly, runs, does NOTHING in-world
const t = Transform.getMutable(engine.PlayerEntity)
t.position.y += 0.1                      // ignored
t.position = Vector3.create(8, 0, 8)     // ignored
Transform.createOrReplace(engine.PlayerEntity, { ... }) // ignored

Symptom to recognize: TypeScript accepts the code, the system ticks, no console error, but the avatar never moves. If you wrote Transform...PlayerEntity and expected motion, this is your bug.

Correct API by intent:

Transform.get(engine.PlayerEntity) is valid for reading position and rotation only.

Player Position and Movement (Reading)

Access the player's position via the reserved engine.PlayerEntity:

import { engine, Transform } from '@dcl/sdk/ecs'

function trackPlayer() {
	if (!Transform.has(engine.PlayerEntity)) return

	const playerTransform = Transform.get(engine.PlayerEntity)
	console.log('Player position:', playerTransform.position)
	console.log('Player rotation:', playerTransform.rotation)
}

engine.addSystem(trackPlayer)

Always check Transform.has(engine.PlayerEntity) before reading player data — it may not be ready on the first frame.

Distance-Based Logic

import { Vector3 } from '@dcl/sdk/math'

function proximityCheck() {
	const playerPos = Transform.get(engine.PlayerEntity).position
	const npcPos = Transform.get(npcEntity).position
	const distance = Vector3.distance(playerPos, npcPos)

	if (distance < 5) {
		console.log('Player is near the NPC')
	}
}

engine.addSystem(proximityCheck)

Player Profile Data

Get the player's name, wallet address, and guest status:

import { getPlayer } from '@dcl/sdk/src/players'

function main() {
	const player = getPlayer()
	if (player) {
		console.log('Name:', player.name)
		console.log('User ID:', player.userId)
		console.log('Is guest:', player.isGuest)
	}
}

• userId — the player's Ethereum wallet address (or guest ID)
• isGuest — true if the player hasn't connected a wallet

Check isGuest before attempting any wallet-dependent feature (guests have no on-chain identity).

Profile Data for Off-Scene Users (Catalyst)

getPlayer(userId) only returns data for users currently connected to this scene. For any other address (parcel owner, NFT holder, leaderboard entry, off-scene claimant), fetch from the catalyst:

GET https://peer.decentraland.org/lambdas/profile/<wallet-address>

• Always use peer.decentraland.org — it is the canonical catalyst regardless of realm/world. Worlds servers do NOT expose /lambdas, so do not blindly read realmInfo.baseUrl.
• Response shape: json.avatars[0].avatar.{ bodyShape, wearables, eyes:{color}, hair:{color}, skin:{color} } (NOT the json[0].metadata.avatars... shape from older docs).
• Unknown address returns { avatars: [], timestamp: 0 } — handle the empty array.
• Colors come as { r, g, b, a } floats in [0,1]. Build a Color3 and pass it directly to AvatarShape.skinColor / hairColor / eyeColor — these fields take a raw Color3, NOT { color: Color3 } (wrapping causes TS2322).

AvatarShape.create({ id: address }) with only an id does NOT auto-fetch wearables — the avatar renders undressed unless you supply bodyShape, wearables, and the color fields explicitly.

Which API to use:

• Local or in-scene player → getPlayer(userId) (sync, includes wearables/emotes).
• Off-scene address → fetchAvatarFromCatalyst(address) (async HTTP).

For the full helper (fetchAvatarFromCatalyst), end-to-end usage example, and gotchas, see {baseDir}/references/catalyst-profile-fetch.md.

Avatar Attachments

Attach 3D objects to a player's avatar:

import {
	engine,
	Transform,
	GltfContainer,
	AvatarAttach,
	AvatarAnchorPointType,
} from '@dcl/sdk/ecs'

const hat = engine.addEntity()
GltfContainer.create(hat, { src: 'models/hat.glb' })
Transform.create(hat, {})

// Attach to the local player's avatar
AvatarAttach.create(hat, {
	anchorPointId: AvatarAnchorPointType.AAPT_NAME_TAG,
})

AvatarAttach requires the target player to be in the same scene — attachments disappear when the player leaves.

Before picking AvatarAttach, decide whether the item is cosmetic or aim-critical. Bone anchors inherit avatar skeleton animation (idle bob, walk cycle, gesture) — great for hats/backpacks/halos, bad for held weapons, aiming reticles, or anything where relative position must stay stable. See Held items vs cosmetic items below.

Held items vs cosmetic items — AvatarAttach vs parenting to engine.CameraEntity / engine.PlayerEntity

SDK7 gives you three distinct mechanisms for "an entity that follows the player". They are not interchangeable — picking the wrong one is the single most common mistake when porting "held item" patterns from SDK6, and the most common subtle failure is parenting an aim-sensitive item (gun, reticle, flashlight) to engine.PlayerEntity and discovering the item does not track camera pitch when the player looks up or down.

Default for any aim-sensitive held item: Transform.parent = engine.CameraEntity. Use engine.PlayerEntity only when you specifically want yaw-only / no-pitch behavior (a body-fixed item the player carries but never aims with).

Why engine.CameraEntity is the right default for aim-sensitive items: engine.PlayerEntity only tracks the player's root (foot position + body yaw). Body yaw is NOT camera pitch — when the player tilts the camera up to aim at a flying target, the player root rotation does not change, so a gun parented to PlayerEntity stays flat and the muzzle doesn't track the look direction. Parenting to engine.CameraEntity inherits both yaw and pitch, so the gun aims where the camera looks. This matches the SDK6 Attachable.FIRST_PERSON_CAMERA behavior creators expect when porting.

Why bone anchors break aim: anchor points like AAPT_RIGHT_HAND, AAPT_SPINE, AAPT_HEAD are positions on the animated avatar skeleton. Every frame the engine pulls the bone's current world transform — which includes the procedural idle bob and any active animation clip. An entity parented there inherits all of that motion. For a weapon, this reads as jitter and makes aiming feel uncontrollable.

Example — gun held in first person (aim follows camera pitch)

import { engine, Transform, GltfContainer, CameraModeArea, CameraType } from '@dcl/sdk/ecs'
import { Vector3, Quaternion } from '@dcl/sdk/math'

const gun = engine.addEntity()
GltfContainer.create(gun, { src: 'assets/Models/blaster.glb' })
Transform.create(gun, {
	parent: engine.CameraEntity,           // gun follows camera (yaw + pitch) — aim tracks where you look
	position: Vector3.create(0.25, -0.2, 0.5), // right, down, forward of camera
	rotation: Quaternion.fromEulerDegrees(0, 0, 0),
	scale: Vector3.One(),
})

If the user does NOT want the item to track pitch (e.g. a held torch that should stay level, not point up when looking up), swap engine.CameraEntity for engine.PlayerEntity. Do not pick PlayerEntity for a gun — the result is a flat-pointing weapon that ignores look direction.

Pair with CameraModeArea or a forced camera mode when equipping a held gun, so the player is in first-person while aiming. See [[camera-control]].

Anti-pattern (what NOT to do for a held weapon)

// WRONG — gun jitters with every idle/walk/gesture animation frame
AvatarAttach.create(gun, {
	anchorPointId: AvatarAnchorPointType.AAPT_RIGHT_HAND,
})

This looks like the right SDK7 way to "put a gun in the avatar's hand" because the API name reads that way — but the hand bone is animated, so the gun is unaimable in practice. Use parenting instead.

// SUBTLY WRONG for a gun — looks correct in hip-fire, fails the moment the player aims up
Transform.create(gun, { parent: engine.PlayerEntity, position: ... })

engine.PlayerEntity inherits body yaw but NOT camera pitch. The gun stays flat when the player looks up to aim at a high target. Use engine.CameraEntity instead for any aim-sensitive item. PlayerEntity is correct only for body-fixed items that should stay level regardless of where the camera points (e.g. a carried lantern, a non-aimed shield).

SDK6 porting note

In SDK7 you have a choice that didn't exist in SDK6. SDK6's Attachable.FIRST_PERSON_CAMERA / Attachable.AVATAR mapped to coarse follow modes only. If you are porting a held item from an SDK6 scene that used Attachable.FIRST_PERSON_CAMERA, the SDK7 equivalent is parenting to engine.CameraEntity (NOT AvatarAttach to a hand anchor, and NOT engine.PlayerEntity — PlayerEntity loses camera pitch). See [[migrate-sdk6-to-sdk7]].

Anchor Points

AvatarAnchorPointType.AAPT_NAME_TAG // Above the head
AvatarAnchorPointType.AAPT_RIGHT_HAND // Right hand
AvatarAnchorPointType.AAPT_LEFT_HAND // Left hand
AvatarAnchorPointType.AAPT_POSITION // [DEPRECATED] Avatar root position — protocol recommends parenting to `engine.PlayerEntity` (body-fixed) or `engine.CameraEntity` (aim-sensitive) instead
AvatarAnchorPointType.AAPT_HEAD
AvatarAnchorPointType.AAPT_NECK
AvatarAnchorPointType.AAPT_SPINE
AvatarAnchorPointType.AAPT_SPINE1
AvatarAnchorPointType.AAPT_SPINE2
AvatarAnchorPointType.AAPT_HIP
AvatarAnchorPointType.AAPT_LEFT_SHOULDER
AvatarAnchorPointType.AAPT_LEFT_ARM
AvatarAnchorPointType.AAPT_LEFT_FOREARM
AvatarAnchorPointType.AAPT_LEFT_HAND_INDEX
AvatarAnchorPointType.AAPT_RIGHT_SHOULDER
AvatarAnchorPointType.AAPT_RIGHT_ARM
AvatarAnchorPointType.AAPT_RIGHT_FOREARM
AvatarAnchorPointType.AAPT_RIGHT_HAND_INDEX
AvatarAnchorPointType.AAPT_LEFT_UP_LEG
AvatarAnchorPointType.AAPT_LEFT_LEG
AvatarAnchorPointType.AAPT_LEFT_FOOT
AvatarAnchorPointType.AAPT_LEFT_TOE_BASE
AvatarAnchorPointType.AAPT_RIGHT_UP_LEG
AvatarAnchorPointType.AAPT_RIGHT_LEG
AvatarAnchorPointType.AAPT_RIGHT_FOOT
AvatarAnchorPointType.AAPT_RIGHT_TOE_BASE
AvatarAnchorPointType.AAPT_NAME_TAG

Anchor points inherit bone animation. Bone-targeted anchors (AAPT_RIGHT_HAND, AAPT_SPINE, AAPT_HEAD, etc.) follow the animated skeleton — idle bob, walk cycle, and gesture animations all propagate to the attached entity. This is correct for cosmetic items (hats, halos, backpacks) and wrong for gameplay items where aim stability matters (guns, reticles). For aim-sensitive items parent to engine.CameraEntity (yaw + pitch — the default for guns/reticles/flashlights); for yaw-only body-fixed items parent to engine.PlayerEntity. See "Held items vs cosmetic items" above.

Attach to a Specific Player

AvatarAttach.create(hat, {
	avatarId: '0x123...abc', // Target player's wallet address
	anchorPointId: AvatarAnchorPointType.AAPT_RIGHT_HAND,
})

avatarId is the target player's wallet address. To attach to every player in the scene (including remote ones), iterate engine.getEntitiesWith(PlayerIdentityData) and read player.address for each — guard with a marker component so you attach only once per player:

import { PlayerIdentityData } from '@dcl/sdk/ecs'

engine.addSystem(() => {
	for (const [entity, player] of engine.getEntitiesWith(PlayerIdentityData)) {
		// player.address is the wallet address to pass as avatarId
	}
})

To attach the local player's own held item, get the address from getPlayer() / await getPlayer() (.userId). Omitting avatarId attaches to the local player. For multiplayer visibility of a held/attached item, sync the anchor entity's AvatarAttach component (see [[multiplayer-sync]]).

Triggering Emotes

Default Emotes

import { triggerEmote } from '~system/RestrictedActions'

// Play a built-in emote
triggerEmote({ predefinedEmote: 'robot' })
triggerEmote({ predefinedEmote: 'wave' })
triggerEmote({ predefinedEmote: 'clap' })

Custom Scene Emotes

⚠️ CRITICAL FILE NAMING REQUIREMENT: The emote .glb file MUST end with _emote.glb (case-insensitive). This is not optional and not just a convention — the runtime rejects files that don't match this suffix.

Why this matters: Scenes with incorrectly named emote files often work fine in npm run start preview but silently fail in production once deployed. Preview is more permissive; the deployed runtime is strict. Always rename the file on disk (e.g. SnowballThrow.glb → SnowballThrow_emote.glb) before deploying.

Valid: wave_emote.glb, Snowball_Throw_emote.glb, dance_EMOTE.GLB Invalid: wave.glb, emote_wave.glb, wave_emote_v2.glb

import { triggerSceneEmote } from '~system/RestrictedActions'

// File MUST end with _emote.glb — rename it on disk if it doesn't
triggerSceneEmote({
	src: 'animations/Snowball_Throw_emote.glb',
	loop: false,
})

Notes:

• Emotes play only while the player is standing still — walking or jumping interrupts them
• If you don't want a player to interrupt an emote, use the InputModifier component to freeze the player for the duration of the emote
• Both triggerEmote and triggerSceneEmote require the scene to declare the ALLOW_TO_TRIGGER_AVATAR_EMOTE permission in scene.json requiredPermissions.
• Both accept an optional mask (upper-body-only animation) — see "Emote masks" below.

Stopping an emote

stopEmote({}) from ~system/RestrictedActions stops the local player's currently playing emote (built-in or scene emote). Useful to end a looping scene emote (triggerSceneEmote({ src, loop: true })) on demand — e.g. a "pick up / put down" toggle.

import { stopEmote } from '~system/RestrictedActions'
stopEmote({})

Detecting when an emote finishes

Every emote lifecycle event is appended to the AvatarEmoteCommand grow-only set on the player entity, with a state field (EmoteState enum). Works for scene-triggered emotes (triggerEmote/triggerSceneEmote), emotes the player plays via the emote wheel, AND other players' emotes (pass their entity instead of engine.PlayerEntity).

import { AvatarEmoteCommand, EmoteState } from '@dcl/sdk/ecs'

AvatarEmoteCommand.onChange(engine.PlayerEntity, (cmd) => {
	if (!cmd) return
	switch (cmd.state ?? EmoteState.ES_STARTED) {
		case EmoteState.ES_STARTED:     // emote started (also the value when `state` is absent — older clients)
			break
		case EmoteState.ES_FINISHED:    // non-looping emote played to its natural end
			break
		case EmoteState.ES_INTERRUPTED: // cut short: movement/jump, teleport, another emote, stopEmote(), or scene exit
			break
	}
})

• Always default absent state to ES_STARTED (cmd.state ?? EmoteState.ES_STARTED) — entries from older clients omit the field, and older clients never send FINISHED/INTERRUPTED at all, so don't hard-block gameplay on a finish signal without a fallback.
• Masked (partial-body) emotes on the local player report no lifecycle events — known limitation.
• Requires a DCL 2.0 desktop client with playback-completion support.
• Verified against protocol avatar_emote_command.proto (commit 215d09c, field 5, optional) and js-sdk-toolchain (commit f858f905).

Emote masks (upper-body only)

Full-body emotes are interrupted when the player walks or jumps — the default locomotion animations take over. AvatarMask.AM_UPPER_BODY limits the animation to the waist up, leaving the legs controlled by locomotion. This means the player can keep walking, running, and jumping while the upper body plays your animation. Use cases: carrying a crate, holding a torch, juggling, cheering while running.

triggerEmote and triggerSceneEmote both accept an optional mask (enum AvatarMask, imported from @dcl/sdk/ecs) that limits which bones the animation drives.

import { AvatarMask } from '@dcl/sdk/ecs'
import { triggerSceneEmote } from '~system/RestrictedActions'

triggerSceneEmote({ src: 'animations/Carry_emote.glb', loop: true, mask: AvatarMask.AM_UPPER_BODY })

• Only value: AvatarMask.AM_UPPER_BODY (= 0). Omitting mask plays the full-body animation (the default) — there is no AM_FULL_BODY value in the enum.
• mask applies to triggerEmote and triggerSceneEmote only. stopEmote({}) takes no arguments (StopEmoteRequest is empty).
• Loop + mask interaction: loop: false with mask: AM_UPPER_BODY plays the upper-body animation exactly once, then returns the upper body to locomotion. loop: true with the mask repeats until stopEmote({}) is called. The loop flag is respected regardless of the mask. Verified against sdk7-test-scenes 88,-13-avatar-masks and 80,-1-scene-emotes (commit 1c0f394).
• Mobile support: Avatar Masks (upper-body-only emotes) ship on mobile in v1.13.0 (September 2026). Until then the mobile renderer plays masked emotes as full-body. Verified against docs commit 09c5818.
• Verified against protocol restricted_actions.proto / common/avatar_mask.proto (pinned in @dcl/sdk via protocol 0010e70) and sdk7-test-scenes 88,-13-avatar-masks (2026-07-16). Earlier speculative names AvatarEmoteMask / AEM_UPPER_BODY / AEM_FULL_BODY were never released — do not use them.

NPC Avatars

For creating NPCs (characters, shopkeepers, guards, etc.), see the npcs skill. It covers both the NPC Toolkit library (GLB-based, with dialogue and movement) and AvatarShape-based avatar NPCs.

Avatar Modifier Areas

Modify how avatars appear or behave in a region.

import {
	engine,
	Transform,
	AvatarModifierArea,
	AvatarModifierType,
} from '@dcl/sdk/ecs'
import { Vector3 } from '@dcl/sdk/math'

const modifierArea = engine.addEntity()
Transform.create(modifierArea, {
	position: Vector3.create(8, 1.5, 8),
	scale: Vector3.create(4, 3, 4),
})

AvatarModifierArea.create(modifierArea, {
	area: Vector3.create(4, 3, 4),
	modifiers: [AvatarModifierType.AMT_HIDE_AVATARS],
	excludeIds: ['0x123...abc'], // Optional: exclude specific players
})

Available Modifiers

AvatarModifierType.AMT_HIDE_AVATARS // Hide all avatars in the area
AvatarModifierType.AMT_DISABLE_PASSPORTS // Disable clicking on avatars to see profiles
AvatarModifierType.AMT_HIDE_NAMETAGS // Hide the name tag above avatars in the area

modifiers is an array — combine several, e.g. [AMT_HIDE_NAMETAGS, AMT_DISABLE_PASSPORTS]. The AvatarModifierArea component takes both an area: Vector3 field (the region size) AND the entity's Transform.scale; set both to the same size. excludeIds is an array of wallet addresses that stay unaffected (e.g. keep the scene owner visible); mutate it at runtime via AvatarModifierArea.getMutable(entity).excludeIds = [...].

AMT_HIDE_AVATARS hides both avatars AND nametags — do not combine it with AMT_HIDE_NAMETAGS (redundant). Use AMT_HIDE_NAMETAGS only when you want nametags hidden while keeping avatars visible (e.g. stages, presentations, clean visual experiences). AMT_HIDE_NAMETAGS is combinable with AMT_DISABLE_PASSPORTS.

Nametag hiding is head/torso based: the nametag is hidden only while the player's head or torso is inside the area. If the area is too short, a player who double-jumps above it will have their nametag briefly reappear. Make the area tall enough to cover the expected range of movement.

Creator Hub / Inspector support: the Creator Hub now has a dedicated inspector panel for AvatarModifierArea with a multi-select dropdown for modifiers (Hide Avatars, Disable Passports) and a wallet-address list editor for excludeIds. A "Avatar Modifier Area" smart item (utils category, translucent placeholder cube) is available in the asset catalog. The editor keeps the area field invisibly in sync with the entity's Transform.scale (the runtime reads area, not scale, for the region size), so resizing the entity via the gizmo automatically updates the modifier region. Note: the inspector panel exposes only AMT_HIDE_AVATARS and AMT_DISABLE_PASSPORTS in its dropdown; AMT_HIDE_NAMETAGS is SDK-only for now. Verified against creator-hub commit a843390a.

Avatar Locomotion Settings

Adjust the player's movement speed and jump height:

import { engine, AvatarLocomotionSettings } from '@dcl/sdk/ecs'

// Modify run speed and jump height (set only the fields you want to change)
AvatarLocomotionSettings.createOrReplace(engine.PlayerEntity, {
	runSpeed: 14, // default is 10
	jumpHeight: 3, // default is 1
})

Fields (all float, optional) with client defaults — verified against unity-explorer origin/main CharacterControllerSettings.asset: walkSpeed (1.5), jogSpeed (8, the default movement speed), runSpeed (10), jumpHeight (1), runJumpHeight (1.5), doubleJumpHeight (2), glidingSpeed (6), glidingFallingSpeed (1), hardLandingCooldown (0.75s). See references/avatar-apis.md.

glidingFallingSpeed is a max descent cap — it limits how fast the player falls while gliding, but does not limit upward motion. While gliding, continuous scene forces are 1.5× stronger and can lift the player; see the player-physics skill ("Forces while gliding").

Restrict Locomotion (InputModifier)

Use InputModifier on engine.PlayerEntity to freeze or selectively restrict the player's movement — useful for cutscenes, locked interactions, or controlled game mechanics.

import { InputModifier, engine } from '@dcl/sdk/ecs'

// Freeze all movement
InputModifier.create(engine.PlayerEntity, {
	mode: InputModifier.Mode.Standard({ disableAll: true }),
})

// Remove restrictions
InputModifier.deleteFrom(engine.PlayerEntity)

Behavior when frozen: gravity and external forces still apply, camera rotation stays available, global input events are still detectable, restrictions lift automatically when the player leaves scene bounds.

Standard-mode flags (all boolean, on InputModifier.Mode.Standard({...})): disableAll, disableWalk, disableJog, disableRun, disableJump, disableEmote. Protocol also defines disableDoubleJump and disableGliding. Note disableJog is separate from disableWalk/disableRun — jog is the default movement speed, so disabling only walk+run still lets the player jog.

The mode can be built two equivalent ways — the InputModifier.Mode.Standard({...}) helper, or the raw discriminated union { $case: 'standard', standard: {...} }.

Tip: Combine with triggerSceneEmote — freeze the player during an animation, then remove InputModifier when it ends.

For the cutscene pattern, see the advanced-input skill.

Teleporting the Player

movePlayerTo from ~system/RestrictedActions is the only way to relocate the player to a position. Setting Transform.getMutable(engine.PlayerEntity).position does NOT work (see the read-only warning at the top of this file). For sustained forces (lift, knockback, push, wind), use the player-physics skill instead — movePlayerTo is for explicit teleports/slides, not for forces.

movePlayerTo accepts:

• newRelativePosition — where to move the player (scene-relative Vector3)
• cameraTarget (optional) — a point in space for the camera to face after moving
• avatarTarget (optional) — a point in space for the avatar to face after moving
• duration (optional) — transition time in seconds; if provided, movement can be awaited

Constraints:

• The player must already be inside the scene's bounds for this to work
• The target position must also be within the scene's bounds
• During the transition the avatar passes through colliders (verified: a CL_PHYSICS obstacle placed in the path is passed through)
• Requires the ALLOW_TO_MOVE_PLAYER_INSIDE_SCENE permission in scene.json requiredPermissions
• All fields except newRelativePosition are optional — cameraTarget and avatarTarget may each be omitted or used independently
• The target Y may be elevated (e.g. y: 12) to place the player on a raised platform, not just ground level

Instant teleport

import { movePlayerTo } from '~system/RestrictedActions'

void movePlayerTo({
	newRelativePosition: Vector3.create(8, 0, 8),
	cameraTarget: Vector3.create(8, 1, 12),
	avatarTarget: Vector3.create(8, 1, 12),
})

Smooth transition with duration

When duration is set, movePlayerTo is awaitable. The resolved value has a success boolean — false if the player interrupted the movement with input.

import { movePlayerTo } from '~system/RestrictedActions'

async function teleport() {
	const result = await movePlayerTo({
		newRelativePosition: Vector3.create(1, 0, 1),
		cameraTarget: Vector3.create(8, 1, 8),
		duration: 2,
	})
	if (!result.success) {
		console.log('Movement was interrupted by the player')
	}
}

Prevent the player from interrupting a transition

Combine InputModifier with movePlayerTo to lock movement for the duration:

import { movePlayerTo } from '~system/RestrictedActions'
import { InputModifier, engine } from '@dcl/sdk/ecs'

async function lockedTeleport() {
	InputModifier.create(engine.PlayerEntity, {
		mode: InputModifier.Mode.Standard({ disableAll: true }),
	})

	await movePlayerTo({
		newRelativePosition: Vector3.create(1, 0, 1),
		cameraTarget: Vector3.create(8, 1, 8),
		duration: 2,
	})

	InputModifier.deleteFrom(engine.PlayerEntity)
}

Avatar Change Listeners

React to avatar changes in real-time:

import {
	AvatarEmoteCommand,
	EmoteState,
	AvatarBase,
	AvatarEquippedData,
} from '@dcl/sdk/ecs'

// Detect when the Explorer reports an emote playing on a player.
// AvatarEmoteCommand is written BY THE EXPLORER to report emote playback
// TO the scene -- it is NOT a signal from scene to renderer. It is appended
// to every player entity (local and remote alike).
// Each entry carries an optional `state` field (EmoteState enum) — see
// "Detecting when an emote finishes" above.
AvatarEmoteCommand.onChange(engine.PlayerEntity, (cmd) => {
	if (cmd) console.log('Emote:', cmd.emoteUrn, 'state:', cmd.state ?? EmoteState.ES_STARTED)
})

// Detect avatar appearance changes (wearables, skin color, etc.)
AvatarBase.onChange(engine.PlayerEntity, (base) => {
	if (base) console.log('Avatar name:', base.name)
})

// Detect equipment changes
AvatarEquippedData.onChange(engine.PlayerEntity, (equipped) => {
	if (equipped) console.log('Wearables changed:', equipped.wearableUrns)
})

Additional Anchor Points

Beyond the commonly used anchor points, the full list includes:

• AvatarAnchorPointType.AAPT_POSITION — avatar feet position
• AvatarAnchorPointType.AAPT_NAME_TAG — above the name tag
• AvatarAnchorPointType.AAPT_LEFT_HAND / AAPT_RIGHT_HAND
• AvatarAnchorPointType.AAPT_HEAD — head bone
• AvatarAnchorPointType.AAPT_NECK — neck bone

Need to check the player's wallet before showing avatar items? See the nft-blockchain skill for wallet checks with getPlayer() and isGuest.

Example scenes

Engine-team test scenes (exercised against the real engine):

• 100,102-avatar-attach-test — AvatarAttach on multiple anchor points; enumerates every player via PlayerIdentityData and attaches to player.address; a follower entity reconstructs the attached world position from PlayerEntity + attached Transform.
• 80,-1-scene-emotes
• 4,23-emote-finish — emote completion detection: AvatarEmoteCommand.onChange(engine.PlayerEntity, ...) logging every appended entry as STARTED / FINISHED / INTERRUPTED, with absent state defaulting to ES_STARTED for older explorers. Play an emote out fully to see FINISHED; walk away mid-playback to see INTERRUPTED. Covers both triggerEmote (predefined) and a non-looping triggerSceneEmote. — triggerEmote, triggerSceneEmote (with a deliberately mis-named non-_emote.glb file shown NOT playing), stopEmote, mask: AvatarMask.AM_UPPER_BODY, plus loop: false + mask (plays once, returns to locomotion) and loop: true + mask (repeats until stopped).
• 11,0-move-player-to-duration — movePlayerTo with duration, reading result.success via .then(), InputModifier locking input during the slide, and a CL_PHYSICS obstacle the avatar passes through mid-transition.
• 9,99-modifier-areas — AvatarModifierArea (AMT_HIDE_AVATARS) with runtime-mutated excludeIds, alongside CameraModeArea.
• 10,99-avatar-modifier-hide-nametags — AvatarModifierArea with AMT_HIDE_NAMETAGS: hides nametags while keeping avatars visible.
• 0,1-input-modifier — InputModifier toggling every Standard flag (disableAll/Walk/Jog/Run/Jump/Emote), both via the helper and the raw $case form.
• 80,-4-restricted-actions — movePlayerTo (incl. elevated y, avatarTarget-only turns), triggerEmote, triggerSceneEmote, teleportTo, openExternalUrl.
• 88,-13-avatar-masks — emote masks: looping AvatarMask.AM_UPPER_BODY scene emote + AvatarAttach anchor to hold a synced crate, stopEmote to release. Also includes loop: false + mask pair (plays once then returns upper body to locomotion) and loop: true + mask pair (repeats until stopped) for verifying the masked-emote loop flag is respected.
