OBJS

OBJS (IDE section)

Supported games:
Brief description:	Defines simple objects
IDE Sections: 2DFX • AMAT • ANIM • CARS • HIER • HAND • MLO • OBJS PATH • PEDS • TANM • TOBJ • TREE • TXDP • WEAP

objs is a section in the item definition file in GTA III, Vice City, San Andreas, Liberty City Stories, and GTA IV. It is used to define simple objects. There are also sections to extend default object definitions:

• tobj for defining an additional in-game time range the object gets rendered in.
• anim which links an animation to an object.
• tanm which does both of the previously mentioned sections.

Format

# type 3 (III/VC/SA/LCS)
Id, ModelName, TxdName, MeshCount, DrawDistance1, DrawDistance2, DrawDistance3, Flags
# type 4 (SA)
Id, ModelName, TxdName, DrawDistance, Flags
end

Type 1

This is used for non-breakable objects.

	Identifier	Type	Description
A	Id	integer	Unique object identifier.
B	ModelName	string	Name of the model file without extension.
C	TxdName	string	Name of the texture dictionary without extension.
D	MeshCount	integer	Number of meshes. 1 for this type.
E	DrawDistance	float	Draw distance in units.
F	Flags	integer	Object flags

Type 2

This is used for breakable objects.

	Identifier	Type	Description
A	Id	integer	Unique object identifier.
B	ModelName	string	Name of the model file without extension.
C	TxdName	string	Name of the texture dictionary without extension.
D	MeshCount	integer	Number of meshes. 2 for this type.
E,F	DrawDistance1, DrawDistance2	float[2]	Draw distance in units (one for each mesh, only the first is actually used).
G	Flags	integer	Object flags

Type 3

This is used for complex breakable objects.

	Identifier	Type	Description
A	Id	integer	Unique object identifier.
B	ModelName	string	Name of the model file without extension.
C	TxdName	string	Name of the texture dictionary without extension.
D	MeshCount	integer	Number of meshes. 3 for this type.
E,F,G	DrawDistance1, DrawDistance2, DrawDistance3	float[3]	Draw distance in units (one for each mesh, only the first is actually used).
H	Flags	integer	Object flags

Type 4

This is used for non-breakable objects and behaves equivalently to Type 1.

	Identifier	Type	Description
A	Id	integer	Unique object identifier.
B	ModelName	string	Name of the model file without extension.
C	TxdName	string	Name of the texture dictionary without extension.
D	DrawDistance	float	Draw distance in units.
E	Flags	integer	Object flags

GTA IV

objs
ModelName, TxdName, DrawDistance, Flag, unknown, MinX, MinY, MinZ, MaxX, MaxY, MaxZ, SphereX, SphereY, SphereZ, Radius, LODModel
end

Type 1

	Identifier	Type	Description
A	ModelName	string	Name of the .wdr model file without extension.
B	TxdName	string	Name of the .wtd texture dictionary without extension.
C	DrawDistance	float	Draw distance in units.
D	Flag	integer	Object flag
E	unknown	float	Unknown integer (usually 0 but uses other values as high as 32).
F,G,H	MinX, MinY, MinZ	float[3]	Lower left corner of the bounding box for the object.
I,J,K	MaxX, MaxY, MaxZ	float[3]	Upper right corner of the bounding box for the object.
L,M,N	SphereX, SphereY, SphereZ	float[3]	Center of the bounding sphere for the object.
O	Radius	float	Radius of the bounding sphere into all dimensions.
P	LODModel	string	Name of the .wdd file that contains the lod model for the defined modelname; otherwise null.

GTA IV stores bounding information inside the item definitions for better performance. The previous games stored bounding information inside the collision files. Also it uses the hashes of the model names as a key of an hash table instead of the ID as an index to the definition array for previous games.
