CPointTeleport_Teleport Function Location Workflow

Overview

Locate the CPointTeleport_Teleport virtual function in CS2 server binary. This function handles teleportation logic for point_teleport entities, including parent object validation and target resolution.

Location Steps

1. Search for Signature String

Use find_regex to search for the teleport error string:

mcp__ida-pro-mcp__find_regex(pattern="can't teleport object.*as it has a parent")

Expected result: Find string like ERROR: (%s) can't teleport object (%s) as it has a parent (%s)!\n

2. Find Cross-References

Use xrefs_to to find locations that reference this string:

mcp__ida-pro-mcp__xrefs_to(addrs="<string_addr>")

Expected result: Find 1-2 functions referencing the string. The smaller function (~0x1d0 bytes) is CPointTeleport_Teleport.

3. Rename Function

Use rename to give the function a meaningful name:

mcp__ida-pro-mcp__rename(batch={"func": {"addr": "<function_addr>", "name": "CPointTeleport_Teleport"}})

4. Get VTable Information

• ALWAYS Use SKILL /get-vtable-from-yaml with class_name=CPointTeleport.

  If the skill returns an error, STOP and report to user.

  Otherwise, extract these values for subsequent steps:

  • vtable_va: The vtable start address (use as <VTABLE_START>)
  • vtable_numvfunc: The valid vtable entry count (last valid index = count - 1)
  • vtable_entries: An array of virtual functions starting from vtable[0]

5. Find VTable Index

• ALWAYS Use SKILL /get-vtable-index to get vtable offset and index for the function.

  VTable class name: CPointTeleport

6. Generate and Validate Unique Signature

• ALWAYS Use SKILL /generate-signature-for-function to generate a robust and unique signature for CPointTeleport_Teleport.

7. Write IDA Analysis Output as YAML

ALWAYS Use SKILL /write-vfunc-as-yaml to write the analysis results of CPointTeleport_Teleport.

Required parameters:

• func_name: CPointTeleport_Teleport
• func_addr: The function address from step 2
• func_sig: The validated signature from step 6

VTable parameters:

• vtable_name: CPointTeleport
• vfunc_offset: The offset from step 5
• vfunc_index: The index from step 5

Function Characteristics

The CPointTeleport_Teleport function contains:

• Error string: ERROR: (%s) can't teleport object (%s) as it has a parent (%s)!\n
• Error string: ERROR: (%s) target '%s' not found. Deleting.\n
• Position/rotation data handling via helper functions
• Parent object validation logic
• Target entity resolution

VTable Information

• VTable Name: CPointTeleport
• VTable Mangled Name:
  • Windows: ??_7CPointTeleport@@6B@
  • Linux: _ZTV15CPointTeleport
• VTable Offset: 0x60 (may change with game updates)
• VTable Index: 12 (may change with game updates)

Output YAML Format

The output YAML filename of CPointTeleport_Teleport depends on the platform:

• server.dll → CPointTeleport_Teleport.windows.yaml
• server.so / libserver.so → CPointTeleport_Teleport.linux.yaml
