Why Cant I compare Vector3s when detecting change in position?

Help and Feedback Scripting Support

I’m writing a Script thats suppose to Detect the player’s Depth and hight, but I’m getting an Error:
“attempt to compare Vector3”

Is there a way to detect change in a Part’s position?

local player = game.Players.LocalPlayer
wait(.5)
local Character = player.Character


while wait() do
	if Character.HumanoidRootPart.Position <= Vector3.new(0,0,0) then
		print("Less Than")
		print(Character.HumanoidRootPart.Position)
	end
	
	if Character.HumanoidRootPart.Position >= Vector3.new(0,0,0) then
		print("Grater Than")
		print(Character.HumanoidRootPart.Position)
	end
end

You can’t compare Vector3’s using <=, <, >, or >= because Roblox doesn’t implement __lt nor __le metamethods.

But a vector of 0, 0, 0 always has a magnitude of 0, so you can detect if the magnitude is >= 0?

Thanks this is probably the solution, but is there a way to just use the Y axis for magnitude?

I figured It out, I used a script @sjr04 made in another Post and just reworked it a bit.

Could you link the post so future readers with the same problem can solve it?

Don’t know if this post is still relevant but you could do every axis individually because it’s not technically comparing Vector3’s.

if Character.HumanoidRootPart.Position.X <= 0 and Character.HumanoidRootPart.Position.Y <= 0 and Character.HumanoidRootPart.Position.Z <= 0 then
print("Less Than")
	print(Character.HumanoidRootPart.Position)
end
