cocos2dx新研发的游戏，手机运行时非常热，有需要的朋友可以参考下。
cocos2dx新研发的游戏，手机上运行时导致手机非常热，后来听其他项目组分享时得知，可以通过降帧解决这个问题，原来是cocos2dx默认的60，后来修改为30，测试发现，手机发热问题解决了。
修改代码：
AppDelegate.cpp
// set FPS. the default value is 1.0/60 if you don‘t call this
pDirector->setAnimationInterval(1.0 / 30);
还有就是：Cocos2dxRenderer.java
//private static long sAnimationInterval = (long) (1.0 / 60 * Cocos2dxRenderer.NANOSECONDSPERSECOND); private static long sAnimationInterval = (long) (1.0 / 30 * Cocos2dxRenderer.NANOSECONDSPERSECOND); ... @Override public void onDrawFrame(final GL10 gl) { /* * FPS controlling algorithm is not accurate, and it will slow down FPS * on some devices. So comment FPS controlling code. */ final long nowInNanoSeconds = System.nanoTime(); // should render a frame when onDrawFrame() is called or there is a // "ghost" Cocos2dxRenderer.nativeRender(); final long afterRenderNano = System.nanoTime(); //final long interval = afterRenderNano - mLastTickInNanoSeconds - Cocos2dxRenderer.sAnimationInterval;// afterRenderNano - nowInNanoSeconds;//nowInNanoSeconds - this.mLastTickInNanoSeconds; final long interval = afterRenderNano - nowInNanoSeconds; // fps controlling if (interval < Cocos2dxRenderer.sAnimationInterval) { //Log.d("onDrawFrame", "Cancel frame" + interval + "/" +Cocos2dxRenderer.sAnimationInterval); try { // because we render it before, so we should sleep twice time interval Thread.sleep((Cocos2dxRenderer.sAnimationInterval - interval) / Cocos2dxRenderer.NANOSECONDSPERMICROSECOND); } catch (final Exception e) { } } //this.mLastTickInNanoSeconds = nowInNanoSeconds; }
