然后在飞机上已被添加到游戏，下一步是让它动起来。主要是为了应对触摸事件。

在C++通过重写ccTouchBegan()、ccTouchMoved()、ccTouchEnded()三个函数来响应触摸事件。

在Lua器中就能够了。

1.先设置该图层能够触摸。然后注冊响应函数onTouch

gameLayer:setTouchEnabled(true)	gameLayer:registerScriptTouchHandler(onTouch)

2.onTouch函数有3个參数，第一个是事件的类型（began、moved、ended），后面两个參数就不用多说了。

function onTouch(eventType, x, y)	if eventType == "began" then   		return onTouchBegan(x, y)	elseif eventType == "moved" then		return onTouchMoved(x, y)	else		return onTouchEnded(x, y)	endend

3.分别实现3个触摸事件

local touchBeginPoint = nilfunction onTouchBegan(x, y)	touchBeginPoint = {x = x, y = y}	return trueendfunction onTouchMoved(x, y)	if PlaneLayer.alive() and PlaneLayer.containsTouchLocation(x,y) then 		--local offset = ccpSub(ccp(touchBeginPoint['x'],touchBeginPoint['y']),ccp(x,y))		--local toPoint = ccpAdd(ccp(PlaneLayer.getPlane():getPositionX(),PlaneLayer.getPlane():getPositionY()),offset)		PlaneLayer.moveTo(x,y)	endendfunction onTouchEnded(x, y)	end

function containsTouchLocation(x,y)	local planeRect = plane:boundingBox()	planeRect.origin.x = planeRect.origin.x - 15	planeRect.origin.y = planeRect.origin.y - 15	planeRect.size.width = planeRect.size.width + 30	planeRect.size.height = planeRect.size.height + 30    local b = planeRect:containsPoint(ccp(x,y))    return bend
