cocos2dx lua实现按钮的放大和缩小功能



如下为cocos2dx lua实现的按钮放大缩小功能，使用起来非常简单：

local function buttonEvent(sender,eventType)
	if eventType == ccui.TouchEventType.began then 
		local scale = cc.ScaleTo:create(1,0.8)
 		local ease_elastic = cc.EaseElasticOut:create(scale)
 		sender:runAction(ease_elastic)      
        
	elseif eventType == ccui.TouchEventType.ended then
            	local scale = cc.ScaleTo:create(1,1)
  		local ease_elastic = cc.EaseElasticOut:create(scale)
  		sender:runAction(ease_elastic)
     
	elseif eventType == ccui.TouchEventType.canceled then
            	local scale = cc.ScaleTo:create(1,1)
  		local ease_elastic = cc.EaseElasticOut:create(scale)
  		sender:runAction(ease_elastic)
	end
end
