Allright, i managed it to get quads drawn, but i've got a problem with the texture binding...
Complete class: http://pastebin.com/ufrai5BY
and heres the result: https://www.dropbox.com/s/lvufkd7qapt2cic/2015-01-11_22.15.00.png?dl=0
the first frame you are able to see the correct Texture, but than it draws the icons.png texture...
i try to unbind(release) the texture, but then the item-Bar and everything gets white...
i need to place the right texture back...
ah and when i try to load the image every frame (which of course is little stupid because the VRAM reach its max very fast), the texture gets drawn right, but than the Air bubbels disappeare
any suggestions?
EDIT: Well nevermind, seems Forge don't let you play directly with GL Texturebinding, you have to use "mc.renderEngine.bindTexture(<Texture>);"
so that means drawing fancy Text with Slick-Util (or using other OpenGL-Utils) isn't possible
