OBJS

OBJS is a section in the item definition file. It is used to define standard static map objects.

Format
ID, ModelName, TextureName, ObjectCount, DrawDist, [DrawDist2, ...], Flags

Object Flags
Object Flags in SA are text formatted UInt32-Values (Like nearly all other Flags). To understand them better you have to calculate them to binary numbers. Then You will get the Bitsets of the Flags. 1 means Enabled, 0 disabled.

List of all known flags for San Andreas:

* If there's no Interior the Texture behind the object changes to black (=> IPL | Interior-value) ** Objects needs to be activated using Object.dat (?) Not 100 % known

To connect different flags you have to add the bit which belongs to the flag. Its the same as adding one value to another..

1 + 2 + 16 = 19 1 +  2 = 3

GTA IV
ModelName, TextureName, DrawDistance, Flag1, Flag2, (Bounds min)X,Y,Z, (Bounds max)X,Y,Z, (Bounds Sphere)X, Y, Z, Radius, WDD

Note that GTA IV does not use any unique object ID numbers
