event.phase

Overview

Indicates the collision phase for the physics collision listener:

• "began" — indicates that a collision between two bodies has started initial contact.
• "ended" — indicates that a collision between two bodies has completed.

Example

local function onCollision( event )
    if ( event.phase == "began" ) then
        print( "began: " .. event.object1 .. " & " .. event.object2 )
    elseif ( event.phase == "ended" ) then
        print( "ended: " .. event.object1 .. " & " .. event.object2 )
    end
end
