An *actor* is any thing in the game that moves or performs actions or interactions: Link is an actor, enemies are actors, NPCs are actors, props like grass are actors (Fishing is also an actor, the largest one, but you don't need to know about it). The vast majority of actors are *overlays*, which means they are loaded only when the game needs them.
In the code, each actor is associated to several files: there is
In the code, each actor is associated to several files: there is
- the main .c file, e.g. `src/overlays/actors/ovl_En_Firefly/z_en_firefly.c`
- the actor's Header file, e.g. `src/overlays/actors/ovl_En_Firefly/z_en_firefly.h`

and then for undecompiled actors, various assembly (.s) files, generally including:
- one for the actor's *data* (this usually includes things like its collision information about how to draw it, and various other stuff that is used in it), e.g. `data/overlays/actors/z_en_firefly.data.s`
- one for each function in the actor, e.g. `asm/non_matchings/overlays/actors/ovl_En_Firefly/func_80A13098.s`
The basic process of decomp is to take one of the .s files, run it through a decompilation program (mips_to_c) that reads the ASM very literally, and then, through humen ingenuity, reshape it into code that not only compiles in the first place, but completely matches the original code (well-written or otherwise).
