Idea of this pr is lets user edit collision.
If you wanna edit collision, load it via engineLoadCOL, original collision you can read by model id, but are read-only.

Functions

table engineGetModelCollisionProperties( col theCol / int modelID)
table engineGetModelCollisionData( col theCol / int modelID, collision-shape [, int index ] )
bool,table engineSetModelCollisionData( col theCol, collision-shape, collision-key, int shapeID / table shapeID, mixed value )
bool engineUpdateModelCollisionBoundingBox( col theCol [, float x, float y, float z ] )
bool isModelCollisionLoaded( int modelID )

engineGetModelCollisionProperties

Return table with information about loaded .col file or modelID ( if collision is loadeded )

• boundingBox
• • vecMin {x,y,z} - minimal position of collision
• • vecMax {x,y,z} - maximal position of collision
• • vecOffset {x,y,z} - offset of sphere
• • radius float - radius of bounding sphere
• colBoxes int - number of boxes that collision has
• colSpheres int - number of spheres that collision has
• colTriangles int - number of triangles that collision has
• colVertices int - number of vertices that collision has

isModelCollisionLoaded

Checks whether original collision is loaded and can be read.

engineSetModelCollisionData

Changing collision, returns boolean if success, and false if something wrong, second argument returns all wrong triangles, vertices etc.

engineUpdateModelCollisionBoundingBox

Updates collision bounding box, need to be used if

• Collision shape was move outside current bounding box, otherwise your collision had issues with detection peds, vehicles, other elements collisions
• If you moved collision shape and now bounding box is too big, otherwise gta will needlessly check collision, what unnecessary consume cpu.
