Hi guys. 
Im trying to make a little plane move on screen and learn about this lib and hmm, i got the same problem that i had in java2D and i wanted to know what should i do :
Each time it passes render it moves the sprite BUT, it gets dragged and it doesnt erase the texture that was before unless this code is there :
:point:
