Making gun point to mouse

[Penguin22305 (Pungu)]

Hi

I was wondering how I could make a gun (the gun’s a tool) point towards the players mouse.

Thanks

Make character's arm point toward mouse regardless of character rotation

I’ve never been that well with CFrames and need a little help. I’m trying to make the player’s right arm point toward the mouse, but when the character turns around 180 degrees, it appears to function as if the character wasn’t rotated 180 degrees. IT’s something to do with world and object space, but I’m unsure of how to resolve this issue. When the player rotates is the problem, as it is pointing behind not in front. It’s not taking the current rotation of the character into consideratio…

How to point your hand toward the mouse when holding the tool

I wanted to make a flashlight tool, but I didn’t know the script that the arm points to the mouse, so I looked around, but they pointed to the mouse from start to finish, and the arm The range of motion was also unrestricted. What kind of script should I use to point the mouse only when I have the tool and limit the range of motion of my arm? Thank you.

use CFrame.LookAt(position, mousepos), where position is the CFrame of the gun, and mousepos is, well, the mouse position…

Hi. Unfortunately that’s not working. This is the full code I used:

local handle = script.Parent:WaitForChild("Handle")

local run = game:GetService("RunService")
local player = game:GetService("Players").LocalPlayer
local mouse = player:GetMouse()

tool.Equipped:Connect(function()
	
	run.Stepped:Connect(function()
		
		CFrame.lookAt(handle.Position, mouse.Hit.Position)
		
	end)
	
end)```

Thanks for the help but I have looked at both of them and there solutions is either not what I’m looking for or the rotation is buggy

[bluebxrrybot (blueberry)]

You want the gun to point where the mouse is pointing? Or literally at the mouse?

[Penguin22305 (Pungu)]

I would like it to point to where the mouse is pointing but also have a degrees snap. The first link made the players arm snap backwards and at most angles the arm became detached from the torso

[bluebxrrybot (blueberry)]

This might be able to snap the degrees?

local cf -- CFrame result from the other tutorials

local x, y, z = cf:ToOrientation()

local degreesnap = 10

x = math.floor(x/degreesnap)*degreesnap
y = math.floor(y/degreesnap)*degreesnap
z = math.floor(z/degreesnap)*degreesnap

cf = CFrame.new(cf.Position) * CFrame.Angles(math.rad(x),math.rad(y),math.rad(z))

[Penguin22305 (Pungu)]

Could you please show me the fully code so I know where to put it

[bluebxrrybot (blueberry)]

The tutorials would give you your code. The code I sent ideally will snap the rotation on the cframe.

local handle = script.Parent:WaitForChild("Handle")
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

game:GetService("RunService").RenderStepped:Connect(function()
	if tool:IsDescendantOf(player.Character) then
		local cf -- CFrame result from the other tutorials

		local x, y, z = cf:ToOrientation()

		local degreesnap = 10

		x = math.floor(x/degreesnap)*degreesnap
		y = math.floor(y/degreesnap)*degreesnap
		z = math.floor(z/degreesnap)*degreesnap

		cf = CFrame.new(cf.Position) * CFrame.Angles(math.rad(x),math.rad(y),math.rad(z))
	end
end)

Hi, I think there was a bit of a misunderstanding. It’s not really a snap I wan’t more of a restrict. So that the player can’t pull there arm behind them etc. Sorry if I said it wrong.

Here is the code I got from the first tutorial:

local RunService = game:GetService("RunService")

local plr = Players.LocalPlayer
local char = plr.Character
local mouse = plr:GetMouse()

local armOffset = char.UpperTorso.CFrame:Inverse() * char.RightUpperArm.CFrame

local armWeld = Instance.new("Weld")
armWeld.Part0 = char.UpperTorso
armWeld.Part1 = char.RightUpperArm
armWeld.Parent = char

RunService.Heartbeat:Connect(function()
	local cframe = CFrame.new(char.UpperTorso.Position, mouse.Hit.Position) * CFrame.Angles(math.pi/2, 0, 0)
	armWeld.C0 = armOffset * char.UpperTorso.CFrame:toObjectSpace(cframe)
end)

Could you please implement a restriction system if you can so the gun can’t move behind them

[bluebxrrybot (blueberry)]

Maybe this works?

local player = game.Players.LocalPlayer
local character = player.Character
local mouse = player:GetMouse()

local armOffset = character.UpperTorso.CFrame:Inverse() * character.RightUpperArm.CFrame

local armWeld = Instance.new("Weld")
armWeld.Part0 = character.UpperTorso
armWeld.Part1 = character.RightUpperArm
armWeld.Parent = character

game:GetService("RunService").RenderStepped:Connect(function()
	local cframe = CFrame.new(character.UpperTorso.Position, mouse.Hit.Position) * CFrame.Angles(math.pi/2)
	local armc = armOffset * character.UpperTorso.CFrame:ToObjectSpace(cframe)
	local x,y,z = armc:ToOrientation()
	y = math.clamp(y,-45,45)
	armWeld.C0 = CFrame.new(armc.Position) * CFrame.Angles(math.rad(x),math.rad(y),math.rad(z))
end)

If not, I don’t know.

[Penguin22305 (Pungu)]

No sorry. It ruins the arms position

You’re trying to use CFrame.lookAt to set the rotation of the handle. You can’t do that.
You can use CFrame.lookAt to create a CFrame that has the rotation you want, but then you have to use that CFrame to do something.
You can apply it to a Part using Part:SetCFrame.
You can apply it to a Tool using Tool.Handle:SetCFrame.
You can apply it to Tool.Grip and Tool.GripRight to rotate the gun and make it look like it’s aiming at the mouse.

this makes your arms follow the Y of the mouse:
RightShoulder.C0 = CFrame.new(RightShoulder.C0.Position) * CFrame.Angles(mouse.Hit.LookVector.Y,math.rad(90),0) LeftShoulder.C0 = CFrame.new(LeftShoulder.C0.Position) * CFrame.Angles(mouse.Hit.LookVector.Y,math.rad(-90),0)
this worked for me, also your characters need to be a R6
