This is the 330th UWA technical knowledge sharing push, which selects hot topics in the UWA community, covers UWA Q&A, community posts and other technical knowledge points, to help everyone master and learn more comprehensively.
AssetBundle
Q: Recently upgraded to 2021, I encountered a strange problem. I opened the AssetBundle package, the previous speed was normal, but it became very slow when I entered the scene, I don’t know why it stopped for 1 minute between every 2 scenes, dozens of scenes, the total AssetBundle package is less than 20MB, and I played 1 For half an hour, if I only play these scenes, the speed is normal, and it is very slow when the AssetBundle package is fully played.
