I want my character to always jump a constant height, let's say 3 meters. Also character has double jump ability so he can jump max 6 meters. For example, let's say I have pressed jump key while player is on the ground, and as soon he reaches 1 meter in height, I press jump key again and he performs double jump and reaches 4 meters.
I am really new to box2d and I have figured out that I can make my character jump using
body.applyForceToCenter(new Vector2(0, 700), true) but I do not know how much force I need to apply in order to make my character jump exactly 3 meters and perform double jump to jump again exactly 3 meters.
I think what I really need here are just formulas...
