Entity

This article is for the Crash 2/3 entity format.

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

Format

Offset	Field	Size	Value
0x0	Length of this item	4 bytes	*
0x4	Parent Zone Pointer (reserved)	4 bytes	*
0x8	Parent Entity Pointer (reserved)	4 bytes	*
0xC	Field count	4 bytes	hc
0x10	Field info structures (headers)	hc * 8 bytes	*
>=0x18	Field data structures (data)	(varies)	*
Field Info Structure
0x0	Type	2 bytes	*
0x2	Offset to the field data relative to 12 bytes at the start of the item	2 bytes	offset
0x4	Flags	Byte	*
0x5	Element size	Byte	es
0x6	Group count	2 bytes	rc
Field Data Structure
0x0	Element count	2 bytes * rc	ec
0x0 + rc * 2	Metavalues (not present if flag 32 not set)	2 bytes * rc	*
0x0 + rc * 4	Data	es * ec * rc	*

Type

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

Type	Name	Purpose	Format	Uses Metavalues?
0x29	Camera Mode	Determines the behavior of the camera trail - similar to Crash 1 camera mode	UInt8 (Crash 2) Int32 (Crash 3)	No
0x2C	Name	String of characters for the internal name used to refer to the entity. Its only purpose is for the devs to distinguish entities so whatever you put here won't directly affect the game	Unspecified	No
0x32	Depth modifier	Modifier optionally applied to the object, usually to correct bad automatic depth sorting (i.e. force objects to appear behind certain scenery)	Int32	No
0x4B	Position	List of position points to be used by the entity. More than one position 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	No
0x9F	ID	Value to uniquely identify the entity that is used to draw it, destroy it, and other miscellaneous behavior	Int321	No
0xA4	Arguments	List of values that affect an object's behavior (i.e. flags, timings, speed, etc.). These are the arguments pushed to GOOL stack before the object's appropriate spawn code runs.	Int32	No
0xA9	Type	Type of the entity (index of GOOL entry in GOOL entry list in the NSD?)	Int32	No
0xAA	Subtype	Variant of the entity - used as an index to the subtype table when spawning the object	Int32	No
0xC9	Camera movement unit	Specifies the amount of "distance" between two camera points. This "distance" translates to a multiplication of the direction vector for Crash-linked camera modes, is not necessary on automatic trails	Int32	No
0x103	SLST EID	EID of the SLST entry to be used by this camera trail	Int32	No
0x109	Neighbor camera trails	Contains information about neighboring camera trails. If one position contains multiple trails, special collision nodes will determine which to use. Trail settings are same as Crash 1, in reverse order.	Int32	Yes
0x118	Misc Settings 1	???	Int32	No
0x130	Field-of-View timeline	Determines the field of view. A value of 200 is the "normal" field of view. The end result is interpolated between the "keyframes" of this property. It is unknown if multiple FOV values can be used on the same position.	Int32	Yes
0x13B	Draw List A	List of values that determine which entities should despawn while the camera is in this zone - includes zone index and entity index2	Int32	Yes
0x13C	Draw List B	List of values that determine which entities should spawn while the camera is in this zone - includes zone index and entity index2	Int32	Yes
0x173	Camera index	Specifies the index of this entity within the zone's list of cameras	Int32	No
0x174	Camera sub-index	Specifies the index of this entity within the camera's list of entities (i.e. values should be 0, 1 or 2)	Int32	No
0x208	Load List A	List of EIDs to load when the camera is in this zone2	Int32	Yes
0x209	Load List B	List of EIDs to deload when the camera is in this zone2	Int32	Yes
0x277	Misc Settings 2	Value that can be used to change a certain object's DDA behavior (i.e. deaths until DDA checkpoint) or other settings like Y rotation.(?)	Int32	No
0x287	Victims	List of entity IDs to destroy on certain occasions (i.e. TNT is despawned, Nitro Switch activated)	Int16	No
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	No
0x28B	Box count	Number of boxes in the level; Only used by obj_willy	Int32	No
0x30E	Scale modifier	Indicates the scale of the object. Crash 3-only; 0 = Position/4 in-game; 1 = Position/2 in-game; 2 = Normal; 3 = Position*2 in-game; etc.	Int32	No
0x336	Time Trial reward	Affects what the crate will reward (and consequentially turn into) during time trial mode. Crash 3-only	Int32	No
0x337	Bonus box count	Number of boxes in the level's bonus; Only used by obj_willy. Crash 3-only	Int32	No

¹ Should fall within Int16 boundaries, as it is the common type used for entity ID-related operations.

² The roles of these lists is reversed when the camera is going backwards.

NOTE: When proceeding from one camera path to the next, all entities should be despawned at the "connection" point for proper disposal of resources. Same applies to entry loading and disposal, as the game seems smart enough not to dispose of resources it's also immediately told to load.
