How do I rotate a line in angle steps?

Hello guys! I use a line with this code:

Line:

.....width: distance(X,Y,Mouse.X,Mouse.Y)

.....angle: angle(X,Y,Mouse.X,Mouse.Y)

What i want is when i move the mouse around, the line to follow and do angle steps (to jump from the first angle to the other - depend when mouse is).

Let's say for example: Each 30 degrees.

Any help? Thanks!

You can do:

floor(angle(Self.X, Self.Y, Mouse.X, Mouse.Y) / 30) * 30

Perhaps round() instead of floor() would feel better.

It works! Many thanks! :)
