find-CPointTeleport_Teleport Skill: поиск телепорта в CS2

--- name: find-CPointTeleport_Teleport description: | Find and identify the CPointTeleport_Teleport virtual function in CS2 binary using IDA Pro MCP. Use this skill when reverse engineering CS2 server.dll or libserver.so to locate the teleport handler function for point_teleport entities. Triggers: CPointTeleport_Teleport, point_teleport, teleport entity, can't teleport object disable-model-invocation: true --- # 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` - `libserver.so` / `libserver.so` → `CPointTeleport_Teleport.linux.yaml`
