Corona中的碰撞事件

Question

我想知道如何讓我的碰撞在Corona中正確工作。這是我到目前爲止：

local function onLocalCollision(event) 

if (event.phase == "began") then 

    print("began: " .. event.object1.myName .. " and " .. event.object2.myName) 
    test = display.newRect(screenW - 50, halfH, 100, screenH) 


elseif (event.phase == "ended") then 

    print("ended: " .. event.object1.myName .. " and " .. event.object2.myName) 

end 

lilPig.collision = onLocalCollision 
lilPig:addEventListener("collision", lilPig) 

endOfScreen.collision = onLocalCollision 
endOfScreen:addEventListener("collision", endOfScreen) 

如果你能幫助我，這將是偉大的！提前致謝！

Answer 1

我覺得，首先你應該增加一些屬性與碰撞物體，如：

lilPig.myName = "lilPig" 

endOfScreen.myName = "endOfScreen" 

這樣，我們就可以直接檢查它們在碰撞監聽器並且如果我們以後有更多的碰撞的，我們可以很容易地檢查另一個條件。

我們也可以通過RunTime監聽器來實現它。

-------- 

RuntimeListener("collision", onCollision) 

-------- 



function onCollision(event) 
     if (event.phase == "began") then 
     print("COLLISION: ".. event.object1.myName .. " & ".. event.object2.myName) 

      if (event.object1.myName == "lilPig" and event.object2.myName == "endOfScreen") or 
        (event.object1.myName == "endOfScreen" and event.object2.myName == "lilPig") then 

          print("Your code of block for collision event") 

end
