Why Wont This Work?

Asked 197 views1 answers
local player = script.Parent.TargetPlayer.Value
while true do
	wait()
	distance = 20
	if player.Torso.Position - script.Parent.Torso.Position.Magnitude <= distance then
		script.Parent.Humanoid:MoveTo(player.Torso.Position)
	end
end

this is a pathfind script. i want the npc to follow the player in targetplayervalue. targetplayervalue is an object value. when i play this script in a npc it does not work. how can i fix this? in output the error says Workspace.hhhh.FireScript:5: bad argument #2 to '?' (Vector3 expected, got number)

player.Torso.Position - script.Parent.Torso.Position.Magnitude

Here's what this line is doing: You get the magnitude of script.Parent.Torso.Position, then subtract that number from your torso's position. This is why you get the error; you're subtracting a number from a Vector3.

What you want to do is get the magnitude of the difference between the two positions.

(player.Torso.Position - script.Parent.Torso.Position).magnitude

The parentheses cause the positions to be subtracted, then the magnitude is taken out of the result of the subtraction, giving you the distance between the points.
