Thx alot man, you helped me with everything 
I thought the enable 2dTexture thingie was something you had to do when you used textures but now i know its more of an option to say: āthe following drawings are texturedā¦ā.
I indeed had to reload the texture when i went fullscreenā¦ kind of stupid when you think about it, in larger applications reloading all you textures would take some serious time.
Thx man, iām gonna build an object orientated version now of space invadersā¦ this was a test to get familiar with the basics of texturing.
