Beamng Mods

BeamNG + BeamMP Modding

Build, scaffold, and debug:

• BeamMP server plugins
• BeamMP client mods (modScript.lua + GE extension)
• BeamNG Lua extensions (common/ge/vehicle)

Keep responses concise and implementation-first. Prefer small working patches.

First Decision

Choose one target before writing code:

1. beammp-server
2. beammp-client
3. beamng-only

If target is unclear, ask one short clarifying question.

Progressive Loading

Load only what is needed.

For beammp-server:

• references/layouts.md
• references/beammp-server-api.md
• examples/beammp-server-main.lua (when scaffolding code)

For beammp-client:

• references/layouts.md
• references/beammp-client-api.md
• examples/beammp-client-extension.lua
• examples/modScript.lua

For beamng-only:

• references/layouts.md
• references/beamng-extension-api.md
• examples/beamng-ge-extension.lua (or adapt for common/vehicle VM)

Core Rules

• Namespace custom events as pluginName:eventName.
• Use JSON payloads for client/server boundaries and validate inputs.
• Keep event handlers short; avoid long blocking loops/sleeps.
• Prefer one small, testable feature per iteration.
• If any local stubs are provided, treat them as helper hints only; prefer official docs on conflicts.

Output Format

When implementing/scaffolding, include:

1. Target type (beammp-server, beammp-client, or beamng-only)
2. Final file tree
3. Code changes
4. Quick test steps
