How would I move a welded object in one axis while the other is moving?
Explanation
Imagine you have a moving cube, it is rotating in all axis and moving every second, but, if you weld a sphere hovering 4 studs above it, the rotation of the cube will be relative to it, so the sphere will also be rotating just like the cube, and moving in a radius of 4 studs.
Goal
I want the sphere to stay in the same position above the cube
Attempt
cube = workspace.cube
sphere = workspace.sphere
Weld = Instance.new("Weld")
Weld.Parent = cube
Weld.Part1 = sphere
Weld.Part0 = cube
Height = 4
while wait() do
Weld.C0 = cube.CFrame:Inverse() * sphere.CFrame * CFrame.new(0,Height,0)
end
Pre-Solution
The idea that I had was to get the position of the cube, add the height, then turn it into a relative CFrame.
--How to find relative: cube.CFrame:Inverse() * sphere.CFrame

This is a pretty complicated solution so it might not work right away but I had a situation similar to this one day when i was messing around and it was for a ball with a click detector that i needed it to start going up and to the left when i clicked the way i ended up doing it was using body velocity and making a child to a part i had created in the same script to do this i used
local children = Instance.new("BodyVelocity", Part)
to make the body velocity (it was a bit ganky at first but ended up working
the problem i ran into was that it was set to going up but i needed it to go up and to the left so i had to set the body velocity's x, y, z velocity to new values
i did this by putting right under it
children.Velocity = Vector3.new(-10,10,0)
and IT WORKED
so with my new found knowledge i used it to do the childish thing of making a noob start pissing into the sky the final code was
local Click = script.Parent
local brick = script.Parent.Parent
Parts = {}
function whenMouseClick()
for count = 1, 50 do
Parts[count] = Instance.new("Part",game.Workspace.AnthonysPlayground)
Parts[count].Name = "Piss"..count
Parts[count].Color = Color3.fromRGB(164,168,50)
Parts[count].Shape = Enum.PartType.Ball
Parts[count].Size = Vector3.new(0.5,0.5,0.5)
Parts[count].Position = brick.Position + Vector3.new(10, 1, 0)
local children = Instance.new("BodyVelocity", Parts[count])
children.Velocity = Vector3.new(-10,10,0)
print(Parts[count].Name)
wait(0.1)
end
end
Click.MouseClick:connect(whenMouseClick)
and it turned out pretty funny Hope i helped and good luck on your project!
