Algodoo

This is a good tutorial, although there is a better way to do it! Search up "Algodoo Gravity Pad" and you'll find tutorials that have more realistic ways of simulating gravity!

Ok, Thats A Good Scene But There Is A Better Way
Just Put In OnCollide: e.other.postStep = (e)=>{Vel = Vel +[0,0.5] }
And To Cancel The Gravity Just Put The Same Code And Erase The Vel = Vel + [0,0.5]

That doesn't accurately simulate gravity, although you're getting there. Multiplying 0.5 by 60 (assuming simulation frequency is 60Hz) would get you 30 m/s^2. We all know that gravity is 9.8m/s^2, so subtracting 30 by 9.8 would be 20.2 m/s, which is too high. The correct number would be 0.327, but you can just bypass that by writing this:
(e)=>{
vel = vel + [0, 2 * sim.gravityStrength] / sim.frequency
}
One gravity strength to counteract the initial gravity the scene is putting on the object, the second to make it go upwards, and divided by the simulation frequency so it works on different simulation frequencies

Ok I am Making a NEW tutorial :happy:

I mean.
