Hey I want rotate the camera around the humanoidrootpart 90° degree when the player types “Q” but how can I do that?

This picture should help you

This is my script:

local UserInputService = game:GetService("UserInputService")
local Player = game:GetService("Players").LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()

hmrp = Character:WaitForChild("HumanoidRootPart")
local camera = workspace.CurrentCamera
UserInputService.InputBegan:Connect(function(input)

if input.KeyCode == Enum.KeyCode.Q then
camera.CFrame = CFrame.new(math.rad(0 + math.rad(90),0,0)) * hmrp.CFrame
end
end)

 local UserInputService = game:GetService("UserInputService")
 local Player = game:GetService("Players").LocalPlayer
 local Character = Player.Character or Player.CharacterAdded:Wait()
 hmrp = Character:WaitForChild("HumanoidRootPart")
local camera = workspace.CurrentCamera
UserInputService.InputBegan:Connect(function(input)

 if input.KeyCode == Enum.KeyCode.Q then
 camera.CFrame = CFrame.Angles(math.rad(0 + math.rad(90),0,0)) * hmrp.CFrame
 end
 end)

New Edit but still doesnt work

Part of the issue here is that the camera needs to be set to a scriptable state. Also, the camera has to be updated in a RenderStep, as it won’t always stay rotated. That means it has to repetitively be set to a certain angle, vertical, or horizontal offset. Let me see if I can do this for you.


local UserInputService = game:GetService("UserInputService")
local Player = game:GetService("Players").LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
hmrp = Character:WaitForChild("HumanoidRootPart")

local camera = workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable

local HORIZONTAL_OFFSET = 10
local VERTICAL_OFFSET = 4
local ANGULAR_INDEX = 0

game:GetService("RunService").RenderStepped:Connect(function()
	if hmrp then
		camera.CFrame = hmrp.CFrame * CFrame.Angles(0, math.pi * (ANGULAR_INDEX * 0.5), 0)
		camera.CFrame *= CFrame.new(0, VERTICAL_OFFSET, HORIZONTAL_OFFSET)
		camera.CFrame = CFrame.new(camera.CFrame.Position, hmrp.Position)
	end
end)

UserInputService.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.Q then
		ANGULAR_INDEX += 1
	end
end)

EDIT: I’m going to test this rn and fix the bugs
EDIT 2: The code is revised, have a look and test it out

I dont know but it doesnt seem work where do I have to put your script?

Also make sure to copy and paste the new code I edited at the top

Edit: Line 3 has some problems

That’s odd, there doesn’t seem to be an error for me.

I’ll link you the file to the place:

Camera.rbxl (21.9 KB)

If you need a place link, you can test it or copy the place here:

Oh no I understood everything. Thanks :smiley:
