I’m working on a golf ball system, however at certain, high velocities the ball seems to fall through an invisible part just above the terrain. (Placed this part because otherwise the ball kept falling through the terrain.
Any ideas on why this might be happening? Ball size is 1.19, 0.296, 0.594 and mass 0.014
Custom physical properties:
(I will reply if I manage to get a video, this only happens sometimes.)
try increasing mass or make invisible walls bigger?
There are lots of posts about fast moving projectiles going through walls and the ground etc.
The game engine calculates in ‘steps’ or ‘frames’. If your ball is .01 studs from the ground Part in one frame and most of the way through it (or all the way through) in the next frame then it’s expected behaviour.
As @Yarik said, try making your ground Parts thicker.
It’s also due to the size of your Part (ball).
You could also try using a RayCast in the direction of the ball’s travel to see if it’s approaching the ground or another surface and calculate if it should be contacting the ground in the next frame or 2.
