Simple lua function fix

[Numba1stunna1]

Need a quick fix to a simple lua function. It's crashing my client and I need someone's help.

function GroundZ(object)
	local oY,oX,oZ = ObjectPosition(object)
	local intZ = oZ + 1
	while TraceLine(oX,oY,oZ + 3 ,oX,oY,intZ) == nil do
		intZ = intZ - 0.5
	end
	return intZ + 0.5
end

The idea is to find a Z coordinate closest to the ground of an object.TraceLine returns true if 2 points collide. When traceline returns true, it means intZ point is past the ground. Or, perhaps someone has a better way of determining the GROUND COORDINATES OF THE OBJECT'S X,Y. If that still doesn't make sense, imagine a flying object, and I want the coordinates of the ground BENEATH.

Figured out out, no need for a while loop.

This could possibly work if the original position is not too far away from the bottom. A better solution would be to check if the original z is below or above the ground and then trying to get the nearest possible position with a loop, either by approaching the ground z position until a specific threshold (let‘s say a offset of 0.5 to the ground) or by looping so long that the original z switches its plane relative to the ground (lets say you started with a position that lays above the ground and you want to decrease the z coordinate until the z coordinate lays below the ground). I‘ve implemented a mixin of both of these approaches, my function approches the ground but it always ends up 0.1 above the ground even if the original z was initially below the ground. However, I cannot share any snippets unfortunately
