I have a way of getting the position along a beam with a scale of 0 to 1, but I also need the rotation as well, basically a whole CFrame. How do I do that? I’m assuming it still has to do with the bezier curve but idk how to do that math.
What do you mean you need rotation? Mind drawing a sketch?
beam isnt a straight line so u cant just lerp cframes
u already got position from bezier so ur halfway there
for rotation u need the tangent of the curve
ez way:
- get pos at
t - get pos at
t + epsilon(like 0.001) (pos2 - pos1).Unit= forward directionCFrame.lookAt(pos1, pos1 + dir)
that cframe will follow the beam properly
for twisting:
beam roll is just rotation around that forward axis
so do cf * CFrame.fromAxisAngle(dir, roll)
thats literally it
position = bezier
rotation = bezier derivative
