A3D_SetCollisions

Choose what a moving physics object collides with.

Zones see it whatever is chosen.

native bool:A3D_SetCollisions(Physic:physicid, A3D_COLLIDE:flags);

Parameters

Parameter	Description
Physic:physicid	Physics object to change.
A3D_COLLIDE:flags	What it collides with, A3D_COLLIDE_ALL by default.

Returns

• true when it was changed.
• false when physicid is not a moving physics object.

Remarks

Two bodies collide only when each collides with what the other is. Players, vehicles, actors, static objects and the map collide with everything, so the flags of a moving object decide alone. Two moving objects collide when both hold A3D_COLLIDE_OBJECTS.

A3D_COLLIDE_WATER has no effect here. Objects never collide with the water and float with A3D_SetBuoyancy. Zones see an object whatever its flags. See Collision flags.

Example

A ball that passes through players and vehicles but bounces off the map and other balls.

stock Physic:CreateGhostBall(Float:x, Float:y, Float:z) {
    new Physic:ball = A3D_CreateSphere(1598, 0.3, x, y, z, 0.5);

    A3D_SetCollisions(ball, A3D_COLLIDE_MAP | A3D_COLLIDE_STATIC | A3D_COLLIDE_OBJECTS);

    return ball;
}
