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.

Gravity is usually a constant applied to the y value. In your case i would apply it after you get the joystick values ie

SetSpritePhysicsImpulse and/or SetSpritePhysicsForce if a key is pressed should be the solution i think.
And then you have to play around with the values (SetSpritePhysicsMass too)

Hey Boomgate, try posting in the AppGameKit board next time for a quicker response. I noticed you posted two threads before getting an answer, the 2D board is usually for graphics and not programming. Good luck with your project!
