solved how can I make this dude stand on the ground after dropping from a height

[Herbert]

Hey guys
I try to make a simple sport game, so first, I want to make a person stand on a ground  who can run and jump on it, and I have trouble on the jump part,
the dude won't stop by the ground when he is dropping from a height(https://www.babylonjs-playground.com/#1BZJVJ#113)
if the position.y is 0, then the dude can stand fine on the ground

You just need to use the PlaneImposter instead

hi @mr_pinc
PlaneImposter works, but I got this warning(confused

"Attention, PlaneImposter might not behave as you expect. Consider using BoxImposter instead"

[mr_pinc]

Sure but then you need to create a box rather than a plane.

@mr_pinc
well...but that is a ground,  it is weird to use a box to replace it, I think I'll ignore the warning and go for PlaneImposter

@jerome
what do you mean? you mean I can use getHeightAtCoordinates to resolve it? or you mean I can use groundMesh instead of a plane? it is groundMesh already just I named it plane

[jerome]

If you use a GroundMesh (whatever its name), you can get the ground altitude y at any (x, z) 2D coordinates.

In other terms : if your buddy y position is higher than the altitude at buddy position (x, z) then he's above the ground, he can keeping falling else ... up to you

@jerome
oh, got it, you mean I can detect it and control it by myself, then I think getHeightAtCoordinates will be a useful function,

but I expect imposter to do these works  for me, so I will just go for PlaneImposter.
