Unity IAP包位于何处？
我目前正在编写一个编辑器脚本，这将简化我在我的游戏的免费增值和付费版本之间的转换。我想手动导入当我单击服务 – >应用程序内购买下的导入按钮时导入的.unitypackage文件。
我知道函数AssetDatabase.ImportAsset(path)但我首先需要包的路径。
提前致谢！
启用IAP并单击“导入”后，将发生以下情况：
1.Unity将生成随机文件名
FileUtil.GetUniqueTempPathInProject()
2，完整路径将如下构建：
Temp\FileUtil.GetUniqueTempPathInProject()
3.然后，Unity会将.unitypackage添加到该随机文件名的末尾。
现在，你有类似的东西：
Temp\FileUtil.GetUniqueTempPathInProject()+".unitypackage";
4.然后将下载IAP包并将其存储到＃3的路径中。
它看起来像是什么样的插图：
5.然后将文件复制到
Temp\TarGZ
它与＃2生成的文件名一起保存。 没有.unitypackage在最后像＃3 。
UnityEngine.Cloud.Purchasing
6.之后 ，Unity会根据您的问题中提到的AssetDatabase.ImportPackage 而不是 AssetDatabase.ImportAsset(path,false)导入它。
现在您可以看到Unity IAP软件包所在的位置，但您尝试执行的操作几乎没有问题 ：
1.对于要存在的IAP程序包，必须单击“ 服务”选项卡中的导入按钮。 我相信你希望这是自动化的。
2.文件名不是静态的，因此难以检索路径。 从上图中可以看出，此文件夹中还有其他文件。 我们不知道哪一个是AIP包。
3.重新启动Unity时，将删除临时文件夹。 因此下载的IAP包将丢失 。
获取Unity IAP软件包的最佳方法是直接从Unity服务器下载它，然后将其保存到您首选的位置。 下面的代码将下载IAP包并将其存储在：
我试图隐藏AIP url以免它被滥用，Unity也不会改变它。
如果你想将它重新翻译成其他东西，那么要看的两个最重要的函数是downloadAndInstallAIP()和deleteAndDisableAIP() 。
