Creator 2.2.0
平台，模拟器

输出了下 code 为 5，对应 jsb.EventAssetsManager.UPDATE_PROGRESSION

1111926 · 2019年10月26日 07:58

你这代码自己写的还是在网上找的，明显有问题啊！
onCheckUpdateCallBack里面的case jsb.EventAssetsManager.UPDATE_PROGRESSION: 去掉

1111926 · 2019年10月26日 08:57

ok了记得回复一下哟

han_han9 · 2019年10月26日 09:00

确实明显有问题，一下子点醒。非常感谢大佬
