 In order to make the code more readable, you should replace all of these file indexes with enums containing the filename instead. But you don't have to create these enums manually, the decomp already has enums for all resource archives.
 
-You can find the header for the archive in question by pressing VSCode's `Ctrl+P` shortcut and typing `res_` followed by the name of the resource archive.  
-In this example, the header you want is located at `include/d/res/res_bk.h` because the archive is named "Bk". The resource archive's name is not necessarily the same as the actor's name (though in this example it is).
+You can find the header for the archive in question by pressing VSCode's `Ctrl+P` shortcut and typing `assets` followed by the name of the resource archive.

 Once you open the header, search for the file index, e.g. 0x5B:
 
 ```cpp
-BK_BMD_BK_TATE=0x5B,
+dRes_INDEX_BK_BMD_BK_TATE_e=0x5B,
 ```

+modelData = (J3DModelData*)dComIfG_getObjectRes("Bk", dRes_INDEX_BK_BMD_BK_TATE_e);

+
+Note that you use the `INDEX` enum for calls to `dComIfG_getObjectRes`, but some actors (mostly NPCs) instead call `dComIfG_getObjectIDRes`, in which case you should use the `ID` enum, ignoring the `INDEX` enum entirely. For example:
+
+```cpp
+J3DModelData* a_mdl_dat = (J3DModelData*)dComIfG_getObjectIDRes("Jb", dRes_ID_JB_BDL_JB_e);

 If the actor has a 3D model, you can determine what the actor is by simply viewing the model in a model viewer. First, find the .arc file for this actor. Look in the `createHeap` or `useHeapInit` function for this actor. You should see something like:
 
 ```cpp
-(J3DModelData*)dComIfG_getObjectRes("Bk", BK_BDL_BK)
+(J3DModelData*)dComIfG_getObjectRes("Bk", dRes_INDEX_BK_BDL_BK_e),
 ```
 
 This means the actor's .arc in this example is named "Bk". You can find it your copy of TWW's files at `files/res/Object/Bk.arc`.
