Android游戏开发第三天(2)_android cctintby-优快云博客

本文介绍如何使用 Cocos2d-x 实现精灵对象的各种动画效果，包括淡入淡出、颜色渐变及重复动作等，并提供了一个具体的 GameLayer 类实例代码。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

淡入和淡出:fadeOut和fadeIn

颜色渐变，CCTintTo,CCTintBy

颜色需要使用ccColor3B color3B=ccColor3B.ccc3(255,0, 0);创建颜色对象

重复执行某一个action:CCRepeat/RepeatForever,此action可为经过Seq的队列action

问题：遇到了ADB端口被tfadb占用的情形，结束进程即可

下面附上代码GameLayer
