Call of Duty 5: Collision Brushes

This tutorial will explain how to spawn colliders onto models dynamically spawned in a Level. Thanks to Tally for the find!

Definition

A collider is a brush (square or cylinder) on which the player will not go through.

Availaible Colliders

Here is a list of the Collision Brushes from stock:

• collision_geo_128x128x10
• collision_geo_128x128x128
• collision_geo_256x256x10
• collision_geo_256x256x256
• collision_geo_32x32x10
• collision_geo_32x32x128
• collision_geo_32x32x32
• collision_geo_512x512x10
• collision_geo_512x512x512
• collision_geo_64x64x10
• collision_geo_64x64x128
• collision_geo_64x64x256
• collision_geo_64x64x64
• collision_geo_cylinder_32x128
• collision_geo_ramp
• collision_geo_sphere_32
• collision_geo_sphere_64
• collision_wall_128x128x10
• collision_wall_256x256x10
• collision_wall_32x32x10
• collision_wall_512x512x10
• collision_wall_64x64x10

Example

In the level GSC file for mp_airfield, add this:

        spawn_model( "test", "prop_flag_russian", (1886, 2493, 8), (0,0,0) );
	spawncollision( "collision_geo_32x32x128","collider",(1886, 2493, 8), (0,0,0) );

And add the spawn_model() method at the bottom of the GSC file:

spawn_model( name, model, origin, angles )
{
	if( !isdefined(model) || !isdefined(name) || !isdefined(origin) )
		return undefined;

	if( !isdefined(angles) )
		angles = (0,0,0);

	spawn = spawn ("script_model",(0,0,0));
	spawn.origin = origin;
	spawn setmodel (model);
	spawn.targetname = name;
	spawn.angles = angles;

	return spawn;
}

This gives you a solid Russian flag in mp_airfield which you cant walk through:
