cocos2d-x 异步加载plist,png等文件

1.png的异步加载

?

1 2	Director::getInstance()->getTextureCache()->addImageAsync(reloadImages[curReloadImgNum], CC_CALLBACK_1(LoadingScene::imageAsyncCallback, this ));

2.plist和png一起的打包资源

废话不多，直接上方法，没有加载plist的api，我们使用如1的方法加载png，然后在回调函数中加载plist。

?

1 2	Director::getInstance()->getTextureCache()->addImageAsync(reloadPlists[curReloadPlistNum]+ "png" , CC_CALLBACK_1(LoadingScene::plistImageAsyncCallback, this ));

注意回调函数的参数，这是plist异步加载的关键，形参是png纹理。

1 2 3 4 5 6

void LoadingScene::plistImageAsyncCallback(cocos2d::Texture2D* texture) { SpriteFrameCache::getInstance()->addSpriteFramesWithFile(reloadPlists[curReloadPlistNum].append( "plist" ), texture); curReloadPlistNum++; loading = true ; }

3.plist和pvr.ccz一起的打包资源

类似2的方法。

?

1 2 3 4 5 6 7 8

Director::getInstance()->getTextureCache()->addImageAsync(reloadPvrPlists[curReloadPvrPlistNum] + "pvr.ccz" , CC_CALLBACK_1(LoadingScene::pvrPlistImageAsyncCallback, this )); void LoadingScene::pvrPlistImageAsyncCallback(cocos2d::Texture2D* texture) { SpriteFrameCache::getInstance()->addSpriteFramesWithFile(reloadPvrPlists[curReloadPvrPlistNum].append( "plist" ), texture); curReloadPvrPlistNum++; loading = true ; }

4.CocosStudio导出的.ExportJson后缀的动画文件

?

1 2 3 4 5 6 7

ArmatureDataManager::getInstance()->addArmatureFileInfoAsync(reloadExportJsons[curReloadExportJsonNum], this , schedule_selector(LoadingScene::jsonAsyncCallback)); void LoadingScene::jsonAsyncCallback( float f) { curReloadExportJsonNum++; loading = true ; }
