===Initialization===
To start the object initialization, the object is called via a Macro preset<ref>[https://github.com/n64decomp/sm64/blob/master/include/macro_presets.inc.c#L47 Goomba Macro Preset]</ref> from the level script, which will prompt it initialization with the attached BehaviorScript. The BehaviorScript is then fetched in [https://github.com/n64decomp/sm64/blob/master/data/behavior_data.c data/behavior_data.c] to start initializaing the object.<br>

For all object, multiple extra operation can and will be done, of which an exhaustive list can be found in [https://github.com/n64decomp/sm64/blob/master/src/engine/behavior_script.c src/engine/behavior_script.c]. The operation done for the Goomba BehaviorScript are:
* Set the object's physics
* Set the object's home
* Drop the object to the floor


 
===Call the Object-specific gameloop behavior===
Call Native Behavior (init behavior) - > [https://github.com/n64decomp/sm64/tree/master/src/game/behaviors Behavior Lists]<br>
There are two typically two types of behavior functions located in the behavior file of an object, which are located in [https://github.com/n64decomp/sm64/tree/master/src/game/behaviors src/game/behaviors]. The "initialization" function, which is typically run once when loading the objects. The "loop" function, on the other hand, is the behavior that will run on every processing frames. The main way to distinguish between them is that the latter is surrounded by "BEGIN_LOOP()" and "END_LOOP()" and always comes at the end of the BehaviorScript.
* This will also set the hitbox, which is usually a struct defined in the same file, but can be different files (boulder for example)<br>
Begin Behavior Loop<br>
* Call loop behavior - > [https://github.com/n64decomp/sm64/tree/master/src/game/behaviors Behavior Lists]<br>
End Loop
