Attempt to perform arithmetic (sub) on Vector3 and number

[ForeverBloxian]

So, I have a camera shaking system for explosions. But for some reason it is producing an error I don’t understand.

This is the error.

Players.ForeverBloxian.PlayerScripts.CamShakeMain:12: attempt to perform arithmetic (sub) on Vector3 and number

This is the line that is erroring

local var0 = game.Players.LocalPlayer.Character.Head.Position - arg1.Position.magnitude / arg1.BlastRadius / 8

If somebody can help me and also help me understand this error, then it would be a great help!

Have you tried reading the error message? It clearly states that you are trying to subtract a Vector3 and a number.

[ForeverBloxian]

This error is still a bit confusing. I’m just looking for a fix because my brain has gone crazy trying to figure this out.

[ForeverBloxian]

Also I’m new to coding so some things are a bit tricky

[AlternativeOrNot (Alt)]

You can’t subtract a Vector3 and a number. You are trying to subtract a part’s position and a number.

[ForeverBloxian]

Ahhh. Now I see it. But I still have no idea on how to fix it since this is very confusing. I do understand the error now.

If you need it, here is the full code:

ShakeDist = 25
local CurrentCamera_v0 = workspace.CurrentCamera
local upval1 = game:GetService("Players").LocalPlayer:WaitForChild("PlayerSettings"):WaitForChild("ReducedShake")
local upval2 = require(game.ReplicatedStorage.CameraShaker).new(Enum.RenderPriority.Camera.Value, function(arg1)
	CurrentCamera_v0.CFrame = CurrentCamera_v0.CFrame * arg1
end)
local var60 = game
function var60(arg1)
	if arg1:IsA("Explosion") then
		local Name_v0 = arg1.Name
		if Name_v0 == "Explosion" then
			local var0 = game.Players.LocalPlayer.Character.Head.Position - arg1.Position.magnitude / arg1.BlastRadius / 8
			if var0 < ShakeDist then
				upval2:Start()
				upval2:ShakeOnce(arg1.BlastRadius / 2, 10, 0, 1.5)
			end
		end
	end
end

game.Workspace.DescendantAdded:Connect(var60)

P.S.
This code is from my friend

What exactly are you trying to achieve with it? What will the result look like?

[ForeverBloxian]

Basically if there is an explosion near the player, their camera will shake.

[AlternativeOrNot (Alt)]

So var0 is the distance from the explosion?

[ForeverBloxian]

Yes that is correct

Just like in math, in programming, division and multiplication are prioritized.
Meaning in this line,

local var0 = game.Players.LocalPlayer.Character.Head.Position - arg1.Position.magnitude / arg1.BlastRadius / 8

you are first calculating the arg1.Position.magnitude / arg1.BlastRadius / 8 part, and only then you subtract it.
To prevent that, cover the subtraction in parentheses:

local var0 = (game.Players.LocalPlayer.Character.Head.Position - arg1.Position.magnitude) / arg1.BlastRadius / 8

[ForeverBloxian]

I am still getting the same error even with this modified line

[AlternativeOrNot (Alt)]

damn i put the parentheses on the wrong spot

local var0 = (game.Players.LocalPlayer.Character.Head.Position - arg1.Position).magnitude / arg1.BlastRadius / 8

[ForeverBloxian]

Alright I will try this out! (char limit)

[ForeverBloxian]

It works! Thanks for helping me! (char limit)
