LookVector on CFrame not working on viewport frame?

Asked by

Hello I am trying to do a viewport frame script. The problem is when i'm using a CFrame for a camera for the viewport frame this happens

14:28:09.213 - game.Workspace.Viewportcam.CFrame = game.Workspace.Cam.CFrame.LookVector:1: invalid argument #3 (CFrame expected, got Vector3) 14:28:09.215 - Stack Begin 14:28:09.225 - Script 'game.Workspace.Viewportcam.CFrame = game.Workspace.Cam.CFrame.LookVector', Line 1 14:28:09.227 - Stack End

What I want to achieve is there is a part above the viewport frame that the camera will face In front of. Now I actually do know that look vector is meant for vector3 but is there a way to use it in a CFrame? Here is the code

game.Workspace.Viewportcam.CFrame = game.Workspace.Cam.CFrame.LookVector * 5
game.StarterGui.SurfaceGui.ViewportFrame.CurrentCamera = game.Workspace.Viewportcam
game.Workspace.Viewportcam.CameraType = Enum.CameraType.Scriptable
game.Workspace.Viewportcam.CameraSubject = game.Workspace.Cam

for i,v in pairs(game.Workspace:GetDescendants()) do
    if v:IsA("BasePart") then
        local vclone = v:Clone()
        vclone.Parent = game.StarterGui.SurfaceGui.ViewportFrame
        game["Run Service"].RenderStepped:Connect(function()
            vclone.CFrame = v.CFrame
        end)
    end
end

For some more info

The local script is in replicated first

Camera is in workspace

Gui is a SurfaceGui (I could use billboard but I want to use surfacegui for this case.)

But in advance thanks!

You are using the CFrame incorrectly check out the CFrame Developer article on it https://developer.roblox.com/en-us/api-reference/datatype/CFrame Benbebop 1049 — 3y

Wait i think i realized do i have to add the look vector to the cframe? kepiblop 124 — 3y

"game.Workspace.Cam.CFrame.LookVector * 5" What were you trying to do User#30567 0 — 3y

In your script as follows:

game.Workspace.Viewportcam.CFrame = game.Workspace.Cam.CFrame.LookVector * 5
game.StarterGui.SurfaceGui.ViewportFrame.CurrentCamera = game.Workspace.Viewportcam
game.Workspace.Viewportcam.CameraType = Enum.CameraType.Scriptable
game.Workspace.Viewportcam.CameraSubject = game.Workspace.Cam

for i,v in pairs(game.Workspace:GetDescendants()) do
    if v:IsA("BasePart") then
        local vclone = v:Clone()
        vclone.Parent = game.StarterGui.SurfaceGui.ViewportFrame
        game["Run Service"].RenderStepped:Connect(function()
            vclone.CFrame = v.CFrame
        end)
    end
end

i would change the 1st line from game.Workspace.Viewportcam.CFrame = game.Workspace.Cam.CFrame.LookVector * 5

game.Workspace.Viewportcam.CFrame = game.Workspace.Cam.CFrame * CFrame.new(game.Workspace.Cam.CFrame.LookVector * 5)

as you was converting the Cframe of the camera part to a Vector3 so i've modified the line so it puts the camera 5 studs away from your camera brick according to its LookVector

As for the rest of your script, it looks good!

Hope this helps!

Oh so basically you multiply the CFrame with the Lookvector by 5? Well now i learnt something new! I will try this out.. kepiblop 124 — 3y

Well apparently no errors but it didn't work because its only a test but I actually got informtion on using look vector on CFrame! I will mark this as a solution because that was the main point. kepiblop 124 — 3y
