Entity

An entity is an item that stores a collection of values (hereafter referred to as "fields") that can represent a game object/camera rail in Crash 2 and 3.

Type

The format and usage of the field data depends on the field type. Incomplete list.

Type	Name	Purpose	Format
0x2C	Name	String of characters for the internal name used to refer to the entity. It has no purpose so whatever you put here won't affect the game	UTF-8 charset
0x4B	Position	List of position points to be used by the entity. Multiple of these can be used to make the entity follow a path (as long as it is programmed to do so)	Int16 for each X, Y and Z coordinate
0x9F	ID	Value to uniquely identify the entity that is used to draw it, destroy it (see victims below) and other miscellaneous behaviors	Int321
0xA4	General Settings	List of values that can be used to change a certain object's behavior (i.e. flags, delay, speed)	Int32 (UInt8 + Int24)
0xA9	Type	Type of the entity	Int32
0xAA	Subtype	Variant of the entity	Int32
0x13B	Draw List A	List of values that determine which entities should despawn while the camera is in this zone; Uses metavalues	Int32
0x13C	Draw List B	List of values that determine which entities should spawn while the camera is in this zone; Uses metavalues	Int32
0x208	Load List A	List of EIDs to load when the camera is in this zone	Int32
0x209	Load List B	List of EIDs to deload (untested) when the camera is in this zone	Int32
0x277	DDA Settings	List of values that can be used to change a certain object's DDA behavior (i.e. deaths until DDA checkpoint)	Int32 (UInt8 + Int24)
0x287	Victim	List of entity IDs to destroy on certain occasions (i.e. TNT is despawned, Nitro Switch activated)	Int16
0x288	Section ID	Value to uniquely identify a "section" of the level and is used in checkpoints for the game to know which DDA checkpoints have been triggered and at what point in the level the player is (i.e. First real checkpoint has this set to 1, the next DDA checkpoint will have a 1 too, the next real checkpoint will have a 2, etc.)	Int32
0x28B	Box count	Number of boxes in the level; Should only be used in obj_willy	Int32
0x30E	Scale	Indicates the scale of the object. Crash 3-only; 1 = Position/4 in-game; 2 = Position/2 in-game; 3 = Normal; 4 = Position*2 in-game; etc.	Int32
0x337	Bonus box count	Number of boxes in the level's bonus; Should only be used in obj_willy; Crash 3 only	Int32

Note: Draw lists store this as an Int16, so setting this to a value higher than that will cause severe issues.

The roles of draw lists is reversed when the camera is going backwards. When proceeding from one camera path to the next, all entities should be despawned at the "connection" point for proper disposal of resources.
