Here, this article will give basic explanation on raycasting.

Do a loop where you raycast down, with the ray length that is half size of your ball character.
For RaycastParams:

local groundRaycast = RaycastParams.new()
groundRaycast.FilterDescendantsInstances = {yourBallCharacter, anythingInvisible}
groundRaycast.FilterType = Enum.RaycastFilterType.Exclude

If your raycast returned something, you can allow jump. I also recommend adding debounce for jumping too.

You could do checking raycast for which ground it’s about to be on every heart beat (task.wait) and then replace it with if the player touches the ground. I haven’t done try this, but you can try the pseudocode. It’s not convenient for performance though, I think.
