Hi guys, I am making a space ship game where I am trying to fly a space ship... gravity is supposed to drag the ship down, and obviously pressing up will thrust it up... and then when you stop thrust it starts dropping back to the ground... but I find that I cant get it to accelerate, it just goes at a constant speed...
My apologies if this shows up twice, I tried to post it before and it just dissapeared.
