Hello,

I decompiled a mod, that allows to draw the health and food-level over the player.

Now it draws some white chars over the player, I think there is something wrong with the "drawTexturedModalRect"-method, but I am too stupid to find the error, because I never worked with "addVertexWithUV" before. Can you help me?
