Gun Aiming System

Help and Feedback Scripting Support
#1

I’m currently working on an aiming script for my FPS gun that im making, Right now I Already have a script that makes the camera move to the impart but the problem is that I can’t move my camera up or down, left ,right.

this is the code:

local player = game:GetService(“Players”).LocalPlayer
local camera = workspace.CurrentCamera
local mouse = player:GetMouse()
local RunService = game:GetService(“RunService”)
local tool = script.Parent
local aimpart = tool.AimPart

tool.Equipped:Connect(function()

mouse.Button2Down:Connect(function()

	camera.CameraSubject = aimpart

	RunService.RenderStepped:Connect(function()
		camera.CFrame = aimpart.CFrame
	end)
end)
mouse.Button2Up:Connect(function()
	camera.CameraType = Enum.CameraType.Custom
end)

end)

tool.Unequipped:Connect(function()
camera.CameraType = Enum.CameraType.Custom
end)

does anyone know how to solve it and how I can get it the camera then moving again? also does anyone know how to get back to your normal camera position so ur not aiming anymore?

Best way to do bullet holes? (Placing imagelabels in surfacegui depending on where the bullet hits)

I would suggest, moving the Gun Model instead of the camera.

#3

the thing is that my camera is on the right position on the gun but I can’t move the camera anymore. so I can aim up or down or whatever.I just stay stuck there. only my camera is stuck btw, I can still move

#4

here is the game so u can see what happens. to aim you have to hold right mouse button.

did you make it public? I can’t join it because the permission levels aren’t allowing me to join.

#6

normally it is already public.

#7

RunService.RenderStepped:Connect(function()
camera.CFrame = aimpart.CFrame
end)

Do you forgot to Disconnect this? ^

local connection

mouse.Button2Down:Connect(function()
    connection = RunService.RenderStepped:Connect(function()
	    --stuff
    end
end)

mouse.Button2Up:Connect(function()
    connection:Disconnect()
end)

thanks, this is already a solution for half the problem. as you see in the game, for some reason I can’t move my mouse when I aim. do you know how I can fix that

#9

this is what I have now and the start and stop aiming works as you can see in the test game.

local player = game:GetService(“Players”).LocalPlayer
local char = player.Character
local camera = workspace.CurrentCamera
local mouse = player:GetMouse()

local RunService = game:GetService(“RunService”)

local tool = script.Parent

local aimpart = tool.AimPart

local connection

local equiped = true

tool.Equipped:Connect(function()
equiped = true
mouse.Button2Down:Connect(function()
if equiped == true then
camera.CameraSubject = aimpart

		connection = RunService.RenderStepped:Connect(function()
			camera.CFrame = aimpart.CFrame
		end)
	end
end)

end)

mouse.Button2Up:Connect(function()
connection:Disconnect()
camera.CameraSubject = char:FindFirstChild(“Humanoid”)
end)

tool.Unequipped:Connect(function()
equiped = false
connection:Disconnect()
camera.CameraSubject = char:FindFirstChild(“Humanoid”)
end)

I still don’t know why I can’t move the gun up or down when aiming, does anyone know why?

This tutorial covers the aiming part, they simply tween the AimPart of the gun to the Camera, I think what you gotta do is just manipulate the CFrames of your Arms(Motor6ds)

Making an FPS Framework: Beginner’s guide [PART 2] - Resources / Community Tutorials - DevForum | Roblox

#11

the problem with that is that im using a tool and I think they are using viewport or at least something that isn’t a tool.

#12

Manipulate the Motor6ds C0(CFrame) of the arms(if you’re R6, it’s located in the Torso)

#14

I’v looked stuff up about manipulation of motor6D but I still don’t understand how I could change the frame of the arm that way and I wouldn’t know how to put the arms back either.

#15

Make a local variable for the origin C0 of the arms then

local originArmC0 = Arm.Shoulder.C0

then when equipped(Put this in the renderstepped connection)

Arm.Shoulder.C0 = originArmC0 * CFrame.Angles()

and when unequipping, just set the Shoulder’s C0 to the origin

Arm.Shoulder.C0 = originArmC0
#16

this really helped out a lot already but there is something wrong I think.

code:
local player = game:GetService(“Players”).LocalPlayer
local char = player.Character
local camera = workspace.CurrentCamera
local mouse = player:GetMouse()

local RunService = game:GetService(“RunService”)

local tool = script.Parent

local Arm = char:WaitForChild(“RightUpperArm”)
local Shoulder = Arm:WaitForChild(“RightShoulder”)

local ShoulderOriginC0 = Shoulder.C1

local connection

local equiped = true

tool.Equipped:Connect(function()
equiped = true
mouse.Button2Down:Connect(function()
if equiped == true then
connection = RunService.RenderStepped:Connect(function()
char:WaitForChild(“RightUpperArm”).RightShoulder.C0 = ShoulderOriginC0 * CFrame.Angles(0,0,1)
end)
end
end)
end)

mouse.Button2Up:Connect(function()
connection:Disconnect()
char:WaitForChild(“RightUpperArm”).RightShoulder.C0 = ShoulderOriginC0
end)

tool.Unequipped:Connect(function()
equiped = false
connection:Disconnect()
char:WaitForChild(“RightUpperArm”).RightShoulder.C0 = ShoulderOriginC0
end)

I ran into 2 problems:
the first problem is that it for some reason only rotates the tool and the other one is that I already have another script that uses the shoulder his C0 so the tool follows the mouse.

i’v uploaded what I have now to the testing game that I send I while ago

#18

What’s wrong is that

connection = RunService.RenderStepped:Connect(function()
    char:WaitForChild(“RightUpperArm”).RightShoulder.C0 = ShoulderOriginC0 * CFrame.Angles(0,0,1)
end)

You don’t have the camera Direction

-- You can use this, INSIDE THE CONNECTION
local camDir = char.HumanoidRootPart.CFrame:ToObjectSpace(camera.CFrame).LookVector
local rot = CFrame.Angles(-math.asin(camDir.Y), math.asin(camDir.X), 0)

CF = CF * rot
#19

it still rotates the gun instead of moving it to the face
