Setting framerate

cocos2d-x C++
#1

Hello,
I want to lower the frame rate in cocos2d-x 3.0 to 30 fps. On iOS it works just fine but when it comes to android the game is still running at ~60 fps instead of the 30 fps, which I set in the AppDelegate.
Is there anything I must do to get it work on android?

Look on forum. On android code responsible for FPS is comented. Check file Cocos2dxRenderer.java ? Look for it.

/cocos2dx/platform/android/java/src/org/cocos2dx/lib/Cocos2dxRenderer.java

My look like this:

	@Override
	public void onDrawFrame(final GL10 gl) {

		long lastTime = System.currentTimeMillis();
		lastTime = System.currentTimeMillis() - startTime;
		if (lastTime < Cocos2dxRenderer.sAnimationInterval) {
			try {
				Thread.sleep(Cocos2dxRenderer.sAnimationInterval - lastTime);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
		startTime = System.currentTimeMillis();
		Cocos2dxRenderer.nativeRender();
	}

And Cocos2dxRenderer.sAnimationInterval is defined as this:

private static long sAnimationInterval = (long) (1.0 / 60 * Cocos2dxRenderer.NANOSECONDSPERSECOND);

Thanks for your help, but in cocos2d-x 3.0 there is no Cocos2dxRenderer.java thats why i can’t use the solution for this problem.

Hi guys,

I’m just starting my first Android port and I’ve run into the same problem. I’m using Cocos2d-x 3 frame rate isn’t being limited to 30 like it should be.

As Sebastian says, the Cocos2dxRenderer.java doesn’t work as the file doesn’t exist on Cocos2d-x 3.

Has anyone found a work around for this yet?

Thanks!
