调用eventListener的对象

Question

情况是我需要访问调用eventListener

的对象

例如： 如果我要添加：balls[ball]:addEventListener( "collision", removeBricks)如何在removeBricks函数中访问balls[ball]？

function removeBricks(event)
    print("caller: " .. balls[ball])
    ...
end
balls[ball]:addEventListener( "collision", removeBricks)

我尝试了什么：

balls["ball"]:addEventListener( "collision", removeBricks(event, balls["ball"]))                

Answer 1

self -> balls[ball]
event.other -> other collided object
