How to use gravity without a plugin?
I kind of did, but it seems to be too heavy, I don’t know why
Plugins like havok, cannon, add a significant amount of size to the project for such a small thing: Just force the meshes down
It’s like using jQuery just to do a fetch 
Does anyone know a better way to do this?
For a falling object, the vertical position under the influence of gravity can be calculated using:
y = y + v * time + 0.5 * gravity * time * time
where y is the starting vertical position, v is the initial vertical velocity, gravity obvious, time overall time.
Minimalistic PG:
Good point. I refrained from applying any formula. And I used moveWithCollisions wrong in this hasty playground.
Works fine like you did without moveWithCollisions
My problem is with the performance of moveWithCollisions.
Any way I apply moveWithCollisions to force gravity (-y) on many meshes (10), my GPU go BRRR!
Even with larger intervals:
It will be in the next merge request
