Thanks for the info!
I have to admit I didn't FULLY grasp the concept of the dt, but I'm going with you here. This is what I have now, however it's still not working properly! Now when I jump it jitters :)
If I remove the Clamp then it doesn't jitter, but it goes above the 15 degrees (obviously).
Also note (don't know if it was clear from my previous screenshot)- when the play falls down I want it to be in he opposite of that degrees. I mean that if when jumping I make it go to -15, then when it falls it should be 15, and then settle on 0 when it hits the ground.
So here's the updated Events Sheet, thanks for the help!
