Description
World Query Collider. Checks if the colliders of two bodies overlap.
(bool) = r3d.World:testOverlap(bodyA,bodyB)
A world query collider is a collider used to perform world queries on it. World queries are manual queries performed on the physics world.
You can use this if you just want to know if bodies are colliding but your are not interested in the contact information.
Parameters
bodyA: (body) the first body to test collisions with
bodyB: (body) the second body to test collisions with
Return values
Returns (boolean) either true or false
Examples
local c = 1
function collisionsEventListener()
if world:testOverlap(shipvp.body, ground01body) then
print("collision", c)
c += 1
end
end
world:setEventListener(collisionsEventListener)
Or
stage:addEventListener(Event.ENTER_FRAME, function(e)
world:step(e.deltaTime)
local bool = world:testOverlap(player1.body, obj01.body)
print(bool)
