find-CCSPlayerController_ChangeTeam

Find CCSPlayerController_ChangeTeam

Locate CCSPlayerController_ChangeTeam in CS2 server.dll or server.so using IDA Pro MCP tools.

Method

1. Search for the debug string:

   mcp__ida-pro-mcp__find_regex pattern="ChangeTeam\(\) CTMDBG"
   

2. Get cross-references to the string:

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

3. Decompile the referencing function:

   mcp__ida-pro-mcp__decompile addr="<function_addr>"
   

4. Rename the function:

   mcp__ida-pro-mcp__rename batch={"func": [{"addr": "<function_addr>", "name": "CCSPlayerController_ChangeTeam"}]}
   

5. Find VTable and Calculate Offset:

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

VTable class name: CCSPlayerController

6. Generate and validate unique signature:

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

7. Write IDA analysis output as YAML beside the binary:

   ALWAYS Use SKILL /write-vfunc-as-yaml to write the analysis results for CCSPlayerController_ChangeTeam.

   Required parameters:

   • func_name: CCSPlayerController_ChangeTeam
   • func_addr: The function address from step 3
   • func_sig: The validated signature from step 6

   VTable parameters (when this is a virtual function):

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

Signature Pattern

The function contains a debug log call with format string:

"%s<%i><%s><%s>" ChangeTeam() CTMDBG , team %d, req team %d willSwitch %d, %.2f

Function Characteristics

• Parameters: (this, team_id) where this is CCSPlayerController pointer, team_id is the target team

Team IDs

• 0: Unassigned
• 1: Spectator
• 2: Terrorist
• 3: Counter-Terrorist

VTable Information

• VTable Name: CCSPlayerController::\vftable'`
• VTable Mangled Name: ??_7CCSPlayerController@@6B@
• VTable Index: 102 (0x66) - This can change when game updates.
• VTable Offset: 0x330 - This can change when game updates.

• Note that for server.so, The first 16 bytes of "vftable" are for RTTI. the real vftable = _ZTV19CCSPlayerController (0x221e390) + 0x10 = 0x221e3A0.

Output YAML Format

The output YAML filename depends on the platform:

• server.dll → CCSPlayerController_ChangeTeam.windows.yaml
• server.so → CCSPlayerController_ChangeTeam.linux.yaml
