Return Values

boolean true if an object is overlapping an instance of the specified class, false otherwise

Example

-- Assume we have "matter" and "antimatter" objects on the frame
-- If any of the opposite objects touch, the game ends
local mClass = mmf.newObjectClass("matter")
local aClass = mmf.newObjectClass("antimatter")
 
if (mClass.testClass(aClass)) then
