How to make angularVelocity relative to camera

Help and Feedback Scripting Support
#1

This is the current script that i have

script.Parent.Humanoid:ChangeState(Enum.HumanoidStateType.Physics)

local uis = game:GetService("UserInputService")
local ball = script.Parent:WaitForChild("PlayerSphere")
while true do
	wait(0.1)
	if uis:IsKeyDown(Enum.KeyCode.W) then

			ball.AssemblyAngularVelocity = Vector3.new(-5 , ball.AssemblyAngularVelocity.Y , ball.AssemblyAngularVelocity.Z)

	elseif uis:IsKeyDown(Enum.KeyCode.A) then

			ball.AssemblyAngularVelocity = Vector3.new(ball.AssemblyAngularVelocity.X , ball.AssemblyAngularVelocity.Y , 5)


	elseif uis:IsKeyDown(Enum.KeyCode.D) then

			ball.AssemblyAngularVelocity = Vector3.new(ball.AssemblyAngularVelocity.X , ball.AssemblyAngularVelocity.Y , -5)


	elseif uis:IsKeyDown(Enum.KeyCode.S) then

			ball.AssemblyAngularVelocity = Vector3.new(5 , ball.AssemblyAngularVelocity.Y , ball.AssemblyAngularVelocity.Z)

	end
end

How can I make the changes in velocity relative to the camera.

Use the balls CFrame.LookVector to move it forward use negative the balls CFrame.LookVector to move it back (-CFrame.LookVector) use CFrame.RightVector to move it right and use -CFrame.RightVector to move it left. This will only work if the ball not actually rolling and is anchored. So if you have a texture on it that you need to see rolling then instead create a small part, put it in the middle of the ball and use a constraint to hold the ball to the part and use the same thiing I said previosuly but only apply it to the part.

Oop forgot to say it’s the player’s character i was going to place this image

I don’t think I can rely on Up/Look/Right Vectors for situations like when the camere points to the front, so I wanted to see if I could bse the movement from the direction of the camera top to bottom
For example:
In this image, the objective left is at the bottom and the right at the top

Can’t you use the character’s humanoid’s MoveDirection?

Didn’t know that was a thing, but will check

#7

Whats the players character? The thing that rotates?; If so, are they able to press say W and D at the same time to move diagnol?

#8

Yes but since the angular velocity is objective and not relative the controls become akward whenever the camera changes position

#9

Instead of using angular velocity maybe try using CFrames?

#10

It’s a physics based game, the ball is supposed to roll

#11

CFrame is Positional and rotational.

#12

Yes but the ball won’t roll if I just change it’s CFrame.
My problem is not with the physics, just with getting the amounts to be relative to the camera

#13

What do you mean relative to the camera? Are you using inputs or just the camera?

#14

You know how when you turn the camera when playing a game and press W your character moves forward relative to you?
I have the input part down but i’m having trouble with the camera.
