cuixueying 这应该是你要的结果 我贴伪代码给你
loadBytes(res.bin, () => {
res.texture = Texture.create(res.source, 0, 0, res.texWidth, res.texHeight);
// res.source.dispose();//提交显卡是异步过程 dispose 会导致texture无效
// setTimeout(() => {
// res.source.dispose();
// }, 1000);
// res.source = null;//texture 也存有引用 并不会释放
res.bin = null;
// createFrames?
