Hello,
i use LWJGL(opengl) and i learn from this tutorial:http://www.youtube.com/watch?v=7G_xtkvyleM
from the beginning everything worked just fine until now:(
i dont know why every time i play this mini game(mine craft 2d) , the window is black and everything get stuck.
why is that happening ?
is that a problem with my processor(intel coreTM 2) ?
or maybe its the display adapters(NVIDIA GeForce 9500 GT)?
help please ! ty.
and if you wanna see my code just ask.
