Find CCSGameRules_GoToIntermission

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

Method

1. Search for Reference String

Search for the string "Going to intermission...":

mcp__ida-pro-mcp__find_regex pattern="Going to intermission"

Note the string address.

2. Find Cross-Reference and Containing Function

Get xrefs to the string address:

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

This will lead to CCSGameRules_GoToIntermission. Rename it:

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

3. Get VTable Index

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

VTable class name: CCSGameRules

4. Generate Signature

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

5. Write Analysis Results as YAML

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

Required parameters:

• func_name: CCSGameRules_GoToIntermission
• func_addr: The function address from step 2
• func_sig: The signature from step 4

VTable parameters:

• vtable_name: CCSGameRules
• vfunc_index: The vtable index from step 3
• vfunc_offset: The vtable offset from step 3

VTable Information

• VTable Name: CCSGameRules::vftable'`
• VTable Mangled Name (Windows): ??_7CCSGameRules@@6B@
• VTable Mangled Name (Linux): _ZTV12CCSGameRules
• VTable Index: 128 - This can change when game updates.
• VTable Offset: 0x400 (128 * 8 = 1024) - This can change when game updates.

• Note that for server.so, the first 16 bytes of "vftable" are for RTTI. The real vftable = _ZTV12CCSGameRules + 0x10.

Output YAML Format

The output YAML filename depends on the platform:

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

func_name: CCSGameRules_GoToIntermission
func_va: 0x18087eba0
