I'm trying to add a new hud element that represents data in a players capability. That works fine, but existing HUD elements break with my additions.

At first, the health bar, hunger bar and exp bar where screwed

 

Source Code

But after adding .post to all the events i managed to fix it somewhat. But now i'm stuck. It's just the hunger bar which is broken now. I tried adding m.renderEngine.bindTexture(Gui.ICONS) but it didn't fix it.

Any idea as to what's going wrong? 

You need to rebind the textures that Minecraft expects to be in place, they can be found at GuiInGame and/or GuiInGameForge
