What is wrong with this script?

Asked Jun 16, 2017356 views2 answers

I'm trying to make a little GUI pop up and display the name of the Brick the mouse is pointing to. Here is my script:

Player = game.Players.LocalPlayer
Mouse = Player:GetMouse()



if Mouse.Target:IsA("BasePart") then
	Player.PlayerGui.Selection.Label.Visible = true
	Player.PlayerGui.Selection.Label.X = Mouse.X
	Player.PlayerGui.Selection.Label.Y = Mouse.Y
	Player.PlayerGui.Selection.Label.Text = Mouse.Target.Name
else
	Player.PlayerGui.Selection.Label.Visible = false
end

But I keep getting this error:

Players.Player1.PlayerGui.LocalScript:6: attempt to index field 'Target' (a nil value)

Does anyone know why this is happening.

Your script could be running before Mouse is set as anything. To prevent this, you'd check if Mouse.Target exists first.

Player = game.Players.LocalPlayer
Mouse = Player:GetMouse()


if Mouse.Target then
	if Mouse.Target:IsA("BasePart") then
	    Player.PlayerGui.Selection.Label.Visible = true
	    Player.PlayerGui.Selection.Label.X = Mouse.X
	    Player.PlayerGui.Selection.Label.Y = Mouse.Y
	    Player.PlayerGui.Selection.Label.Text = Mouse.Target.Name
	else
	    Player.PlayerGui.Selection.Label.Visible = false
	end
end

Keep in mind that the code will only run once unless it's in a loop, so most likely, nothing will happen.

You can't compare a nil value you must do

Player = game.Players.LocalPlayer
Mouse = Player:GetMouse()



if Mouse.Target then
    Player.PlayerGui.Selection.Label.Visible = true
    Player.PlayerGui.Selection.Label.X = Mouse.X
    Player.PlayerGui.Selection.Label.Y = Mouse.Y
    Player.PlayerGui.Selection.Label.Text = Mouse.Target.Name
else
    Player.PlayerGui.Selection.Label.Visible = false
end
