AndEngine TXMLLoader空指针异常

标签: android nullpointerexception andengine tmx

我正在尝试在andengine中加载tmx文件。我已经从AndEngine示例复制了示例并创建了一个我正在加载的新tmx文件。但是我在第tmxLoader.loadFromAsset(“tmx / test.tmx”)行上得到NullPointerException; 。 test.tmx文件只包含一个tile。它提供以下错误日志:

即使我尝试加载示例提供的tmx文件,也会出现同样的错误。知道我哪里错了吗?

我正在使用Tiled Map Editor Vesion 0.8.1应用程序创建tmx文件。

答案 0 :(得分:1)

您是否获取了AndEngine的最新版本? 它接缝已修复:

https://github.com/nicolasgramlich/AndEngineTMXTiledMapExtension/pull/9

编辑:嗯,对不起,拉请求尚未提交。你应该尝试在你自己的git andengine repo中应用它。 或者作为简单的修复,您应该将tile ID更改为不同于0的值。
