重现方式:
1.在场景A设置资源自动回收,放置按钮使用资源BtnA
2.切换到过渡场景B,过渡场景为空场景,没有使用任何资源,过渡场景预加载C场景的资源
3.切换到场景C,场景里也有一个按钮使用资源BtA
4.切换过程异常
查看资源BtA:
var uuid = cc.loader._getResUuid(‘xxx/BtA’ , cc.SpriteFrame);
var id = cc.loader._getReferenceKey(uuid);
var item = cc.loader.getItem(id);
在场景A切B之前:
item.content {
_texture: cc_RenderTexture {_super: null, _name: “”, _objFlags: 0, _native: “”, _hasMipmap: false, …}
_textureFilename: “/Users/lgmacbook/Social/client/library/imports/82/8271caca-47de-4e82-bd31-97bab11daa5c.png”
addLoadedEventListener: (…)
_textureLoaded: (…)
_uuid: “b3642c96-ef93-4ba6-a069-b89bb453158a”
}
场景B切C之后:
_rotated: false
_texture: null
_textureFilename: “”
addLoadedEventListener: (…)
_textureLoaded: (…)
_uuid: “b3642c96-ef93-4ba6-a069-b89bb453158a”
分析:
应该是切过渡场景时,释放了Texture,但是未释放SprieFrame,但是这个BtA资源在过渡场景中未使用到
