It’s best to not touch pTime. That would just advance the simulation forward in time more. It wouldn’t conserve energy.
look at this please.
what if I stop and restore the time in this way? it works for me as it should. the movement continues at the same speed as it was before the stop. I can even set the vx and vy values to start moving at the desired speed.
I need the heaviness so that it jumps not so high, and for more dumping. When I change the gravity, it just move faster or slower, but the amplitude remains the same. I can't figure it out without your help.)
