Questions on over the shoulder camera

Help and Feedback Scripting Support

(this is a repost as the first post had no response)
With the Over-the-Shoulder script in this post, i have a couple questions.

local Players = game:GetService("Players")
local ContextActionService = game:GetService("ContextActionService")
local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")
 
local camera = workspace.CurrentCamera
local cameraOffset = Vector3.new(2, 2, 8)
local player = Players.LocalPlayer
 
player.CharacterAdded:Connect(function(character)
 
	local humanoid = character:WaitForChild("Humanoid")
	local rootPart = character:WaitForChild("HumanoidRootPart")
	humanoid.AutoRotate = false
 
	local cameraAngleX = 0
	local cameraAngleY = 0
 
	local function playerInput(actionName, inputState, inputObject)
		-- Calculate camera/player rotation on input change
		if inputState == Enum.UserInputState.Change then
			cameraAngleX = cameraAngleX - inputObject.Delta.X
			-- Reduce vertical mouse/touch sensitivity and clamp vertical axis
			cameraAngleY = math.clamp(cameraAngleY-inputObject.Delta.Y*0.4, -75, 75)
			-- Rotate root part CFrame by X delta
			rootPart.CFrame = rootPart.CFrame * CFrame.Angles(0, math.rad(-inputObject.Delta.X), 0)
		end
	end
	ContextActionService:BindAction("PlayerInput", playerInput, false, Enum.UserInputType.MouseMovement, Enum.UserInputType.Touch)
 
	RunService.RenderStepped:Connect(function()
		if camera.CameraType ~= Enum.CameraType.Scriptable then
			camera.CameraType = Enum.CameraType.Scriptable
		end
		local startCFrame = CFrame.new((rootPart.CFrame.Position)) * CFrame.Angles(0, math.rad(cameraAngleX), 0) * CFrame.Angles(math.rad(cameraAngleY), 0, 0)
		local cameraCFrame = startCFrame:ToWorldSpace(CFrame.new(cameraOffset.X, cameraOffset.Y, cameraOffset.Z))
		local cameraFocus = startCFrame:ToWorldSpace(CFrame.new(cameraOffset.X, cameraOffset.Y, -10000))
		camera.CFrame = CFrame.new(cameraCFrame.Position, cameraFocus.Position)
	end)
end)
 
local function focusControl(actionName, inputState, inputObject)
	-- Lock and hide mouse icon on input began
	if inputState == Enum.UserInputState.Begin then
		UserInputService.MouseBehavior = Enum.MouseBehavior.LockCenter
		UserInputService.MouseIconEnabled = false
		ContextActionService:UnbindAction("FocusControl", focusControl, false, Enum.UserInputType.MouseButton1, Enum.UserInputType.Touch, Enum.UserInputType.Focus)
	end
end
ContextActionService:BindAction("FocusControl", focusControl, false, Enum.UserInputType.MouseButton1, Enum.UserInputType.Touch, Enum.UserInputType.Focus)

. The function playerInput, how does the Delta property work? Is it only set to something other than 0 if the mouse is moving relative to the camera moving?

. The cameraFocus variable inside of playerInput in the Runservice.RenderStepped, why is the z set to -10000, shouldn’t it set relative to the player like the x and y are as that is closer to the player?

. In the last function focusControl, how come when I take out when the UserInputService properties being set and put them outside of the function of focusControl (the properties still being set) how come the script doesn’t work properly?

Thank you for your time :grinning:

  1. The inputObject.Delta is a vector3 describing the mouse/touch inputs movement. It is being used to calculate how the camera angles should be increment for the new frame draw.
  2. The z offset is relative to the player’s orientation. The z-axis is the direction the player is facing, so it is focusing the camera a point really far out in front of the player so everything in front of the player is in focus.
  3. I’m not sure about this one. Make sure you are putting it in the character added function, you might be setting it before the player spawns.

Hope this helped.
