I want to make a dashing system that moves the player in their camera’s direction, but when i try to set an attatchments rotation to math the camera’s, instead of looking at the cameras up direction. it just changes the SecondaryAxis to always keep it flat
DashAttachment.WorldCFrame = CFrame.new(DashAttachment.WorldPosition, DashAttachment.WorldPosition + cameraDirection)
DashAttachment.Orientation += Vector3.new(0,90,0)
Well, that’s because you’re adding orientation to the cframe that is already pointing in the right direction.
Just as a general rule of thumb, don’t use the Orientation or Rotation properties, they don’t work intuitively. Just use CFrames instead.
As per your problem tho, remove the Orientation part, and just change the cameraDirection variable to be Camera.CFrame.UpVector instead of Camera.CFrame.LookVector if you want the camera’s up direction.
idk if im reading your reply wrong, but my problem is not that it moves on the z axis, but that it ONLY moves on the z axis, also im adding 90 because in my experience attatchemnents are always offset by 90
Okay let me get this straight, do you want the attachment to look exactly in the direction the camera is looking in? Or the upvector of the camera? Or are you looking for something completely different?
I don’t quite get what you mean by moving it, since you only seem to be trying to rotate it.
exactly the cameras lookvector, sorry for the confusion
I mean yeah, in that case what you’re looking for is what I told you, so smth like this.
DashAttachment.WorldCFrame = CFrame.new(DashAttachment.WorldPosition, DashAttachment.WorldPosition + cameta.CFrame.LookVector)
No need for the orientation change.
I will also add on that the secondary axis and primary axis do not represent the look vector.
They only represent the right vector and up vector, the look vector is derived from the cross product of those two.
You can test this by putting an attachment into a new part at 0,0,0 orientation.
So this means in attachment view the arrows will never be pointing along the lookvector and will look weird but its expected.
removing the orientation addition js makes it move the wrong way, also thats literally the same code
i know, but i js wna get it to look upwards
Could this help? This is in a LocalScript in StarterCharacterScripts:
local char = script.Parent
task.wait(1)
local cam = workspace.CurrentCamera
local hum = char.Humanoid
local hrp = char.HumanoidRootPart
local att = Instance.new("Attachment", hrp)
local vectorForce = Instance.new("VectorForce", hrp)
vectorForce.Attachment0 = att
vectorForce.RelativeTo = Enum.ActuatorRelativeTo.World -- Important
vectorForce.ApplyAtCenterOfMass = true
task.spawn(function()
while task.wait() do
--att.WorldCFrame = CFrame.lookAt(hrp.Position, hrp.Position + cam.CFrame.LookVector) -- Not necessary
vectorForce.Force = cam.CFrame.LookVector*20000
end
end)
i know this could and prolly does work, but i asked abt attachments, sorry
Can you send more of the code? I’d like to help, but I don’t have much to go off of except that an attachment is not looking up when you look up, which works if you just do this:
local char = script.Parent
task.wait(1)
local cam = workspace.CurrentCamera
local hum = char.Humanoid
local hrp = char.HumanoidRootPart
local att = Instance.new("Attachment", hrp)
task.spawn(function()
while task.wait() do
att.WorldCFrame = CFrame.lookAt(hrp.Position, hrp.Position + cam.CFrame.LookVector)
end
end)
so I’m probably missing something here.
thats exactly what im doing, cameradirection is the lookvector
I’m saying that code works fine for me. You do not have that exact same code if it doesn’t work for you, so I’d like to see the entirety of the code you have in order to help. I’m talking about more than just those two lines you shared in the OP.
local Services = require(game:GetService("ReplicatedStorage").Modules.ServicesModule)
local Remote: RemoteEvent = Services.ReplicatedStorage.Remotes.DashRemote
Remote.OnServerEvent:Connect(function(Player: Player, cameraDirection: Vector3, Enabled: boolean)
local Character: Model? = Player.Character
local Humanoid: Humanoid = Character:FindFirstChildOfClass("Humanoid")
local RootPart: BasePart? = Humanoid.RootPart
local DashAttachment: Attachment = RootPart:WaitForChild("DashAttachment")
local DashVelocity: LinearVelocity = RootPart:WaitForChild("DashVelocity")
if Enabled == true then
DashVelocity.Parent = RootPart
DashVelocity.Attachment0 = DashAttachment
DashAttachment.WorldCFrame = CFrame.new(DashAttachment.WorldPosition, DashAttachment.WorldPosition + cameraDirection)
DashAttachment.Orientation += Vector3.new(0,90,0)
DashVelocity.Enabled = true
elseif Enabled == false then
DashVelocity.Enabled = false
elseif Enabled == nil then
DashAttachment.WorldCFrame = CFrame.new(DashAttachment.WorldPosition, DashAttachment.WorldPosition + cameraDirection)
DashAttachment.Orientation += Vector3.new(0,90,0)
end
Remote:FireAllClients(Character, inputState)
end)
local function FireDashRemote()
local cameraDirection = Services.Workspace.CurrentCamera.CFrame.LookVector
Services.ReplicatedStorage.Remotes.DashRemote:FireServer(cameraDirection, nil)
end
local function Dash(actionName: string, inputState: Enum.UserInputState, _inputObject: InputObject)
if actionName == "Dash" then
if inputState == Enum.UserInputState.Begin then

script:SetAttribute("DashEnabled", true)
end

end
end
script:GetAttributeChangedSignal("DashEnabled"):Connect(function(...: any)
local cameraDirection = Services.Workspace.CurrentCamera.CFrame.LookVector

This works (assuming you’re using a VectorForce for the force). All I did was remove the orientation changes on the server:
local Remote: RemoteEvent = script.Parent.RemoteEvent
Remote.OnServerEvent:Connect(function(Player: Player, cameraDirection: Vector3, Enabled: boolean)
local Character: Model? = Player.Character
local Humanoid: Humanoid = Character:FindFirstChildOfClass("Humanoid")
local RootPart: BasePart? = Humanoid.RootPart
local DashAttachment: Attachment = RootPart:FindFirstChild("DashAttachment")
local DashVelocity: LinearVelocity = RootPart:FindFirstChild("DashVelocity")
if not DashAttachment then
DashAttachment = Instance.new("Attachment")
DashAttachment.Name = "DashAttachment"
DashAttachment.Parent = RootPart
end
if not DashVelocity then
DashVelocity = Instance.new("VectorForce") :: VectorForce
DashVelocity.Name = "DashVelocity"
DashVelocity.Force = Vector3.new(0, 0, -10000)
DashVelocity.RelativeTo = Enum.ActuatorRelativeTo.Attachment0
DashVelocity.Parent = RootPart
end
if Enabled == true then
DashVelocity.Parent = RootPart
DashVelocity.Attachment0 = DashAttachment
DashAttachment.WorldCFrame = CFrame.new(DashAttachment.WorldPosition, DashAttachment.WorldPosition + cameraDirection)
--DashAttachment.Orientation += Vector3.new(0,90,0)
DashVelocity.Enabled = true
elseif Enabled == false then
DashVelocity.Enabled = false
elseif Enabled == nil then
DashAttachment.WorldCFrame = CFrame.new(DashAttachment.WorldPosition, DashAttachment.WorldPosition + cameraDirection)
--DashAttachment.Orientation += Vector3.new(0,90,0)
end
--Remote:FireAllClients(Character, inputState)
end)
im using a linear velocity, how are they that different
LinearVelocity version works too:
local Remote: RemoteEvent = script.Parent.RemoteEvent
Remote.OnServerEvent:Connect(function(Player: Player, cameraDirection: Vector3, Enabled: boolean)
local Character: Model? = Player.Character
local Humanoid: Humanoid = Character:FindFirstChildOfClass("Humanoid")
local RootPart: BasePart? = Humanoid.RootPart
local DashAttachment: Attachment = RootPart:FindFirstChild("DashAttachment")
local DashVelocity: LinearVelocity = RootPart:FindFirstChild("DashVelocity")
if not DashAttachment then
DashAttachment = Instance.new("Attachment")
DashAttachment.Name = "DashAttachment"
DashAttachment.Parent = RootPart
end
if not DashVelocity then
DashVelocity = Instance.new("LinearVelocity")
DashVelocity.Name = "DashVelocity"
DashVelocity.VectorVelocity = Vector3.new(0, 0, -10)
DashVelocity.MaxForce = 1000000000
DashVelocity.Attachment0 = DashAttachment
DashVelocity.RelativeTo = Enum.ActuatorRelativeTo.Attachment0
DashVelocity.Parent = RootPart
end
if Enabled == true then
DashVelocity.Parent = RootPart
DashVelocity.Attachment0 = DashAttachment
DashAttachment.WorldCFrame = CFrame.new(DashAttachment.WorldPosition, DashAttachment.WorldPosition + cameraDirection)
--DashAttachment.Orientation += Vector3.new(0,90,0)
DashVelocity.Enabled = true
elseif Enabled == false then
DashVelocity.Enabled = false
elseif Enabled == nil then
DashAttachment.WorldCFrame = CFrame.new(DashAttachment.WorldPosition, DashAttachment.WorldPosition + cameraDirection)
--DashAttachment.Orientation += Vector3.new(0,90,0)
end
--Remote:FireAllClients(Character, inputState)
end)
thank you, i have no idea why it didnt work in the first place tho
its cuz it was line, not vector, which is weird
