Rotating a frame + Positioning (Rain Simulation Issue)

So for example you got a frame the size of a rain drop and you rotate it;

local frame = script.Parent
frame.Rotation = 60 -- angle the frame diagonally across the players screen

Generally the raindrop would be at the top of the players screen in a random position on the X axis. The Rotation would give it a diagonal angle allowing me to adjust the position so it goes in the direction which it was rotated. How can I position it the way it’s rotated though?

So, Y would be your speed to fall, and X would be the direction it is going with the angle. Best bet is probably to move it by 10/10 degrees. So for 60 rotation, it should be moving 60 to the side. The way to determine which way is just to check that if the rotation is <=/>= to a certain number means it is pointed one way or another. Hope I helped!
