Class: R3d.World
Description
Checks collisions between two bodies.
r3d.World:testCollision(bodyA,bodyB,callback,category)
Note: this function is not called every frame. To do so, you should put the function in the ENTER_FRAME event or the r3d:setEventListener
Parameters
bodyA: (body) the body A optional
bodyB: (body) the body B optional
callback: (function) the callback function
category: (number) bit mask for collision filtering optional
Example
function callback(e)
print(e.fixture1, e.body1)
print(e.fixture2, e.body2)
print(e.body1.id, e.body2.id)
end
world:testCollision(bodyA, callback)
world:testCollision(bodyA, bodyB, callback, 1)
