assetsManager = cc.AssetsManager:new("http://XXX/XX.zip","http://XX/version",pathToSave) assetsManager:retain() assetsManager:setDelegate(onError, cc.ASSETSMANAGER_PROTOCOL_ERROR ) assetsManager:setDelegate(onProgress, cc.ASSETSMANAGER_PROTOCOL_PROGRESS) assetsManager:setDelegate(onSuccess, cc.ASSETSMANAGER_PROTOCOL_SUCCESS ) assetsManager:setConnectionTimeout(10) --assetsManager:registerScriptHandler(handler(self, self.downHandler)) assetsManager:update()
用assetsManager 这方法两种侦听方式都没收到响应 可能的情况是什么呢？
