Imparts a 1-frame impulse on physics objects radially outward in a cylinder (i.e., all the added forces are parallel to the ground). This can be used to simulate wind from a helicopter.
Example:
PhysicsExplosionCylinder( origin, 50, 40, 1 );
Required Args:
1 : <center> The world position of the center of the cylinder
2 : <outer radius> The radius beyond which the force is zero
3 : <inner radius> The radius within which the force is maximum
4 : <magnitude> The strength of the force. 1 = the default explosion
