TextureAtlas issue with libgdx

问题

I keep getting null pointer exceptions when I try and use TextureAtlass with this libgdx project. game.atlas and game.png are under android/assets

game.png
size: 1024,1024
format: RGBA8888
filter: Nearest,Nearest
repeat: none
bunny_head
  rotate: false
  xy: 2, 44
  size: 122, 82
  orig: 122, 82
  offset: 0, 0
  index: -1

Load the atlas with

TextureAtlas atlas = new TextureAtlas(Gdx.files.internal("game.atlas"));
head = atlas.findRegion("bunny_head");

This is my Exception log

Exception in thread "LWJGL Application" java.lang.NullPointerException

回答1:

How are you running your project? If it's from within an IDE on the desktop, have you remembered to set the current working directory to be android/assets?

If not, then it won't find game.atlas which could cause the issue you see.

Appologies for posting this as an answer btw - I don't have enough reputation to post it as a comment.
