For some good reason i am using JOGL .... Every other thing works well, including the static renderings, but the Input key binding keyListener doesn't work, I have got no clues why. I am hoping expert eyes inspection would be able to see whats wrong and also hope this code is small and clear enough for someone to be able to inspect it with ease
Many thanks
(I can't find code formatting tags, tried to make one but it isnt working. So apologies for the code, when I find code tags appear in menu , i will edit thread)
