Hello reader,

I am struggling creating an expression to constrain movement of a layer to a certain angle. I found this isometric expression which works great:

pos = transform.position;

x = effect("X Movement")(1);

z = effect("Z Movement")(1);

y = effect("Y Movement")(1);

[x*Math.sqrt(3) + z*Math.sqrt(3) + pos[0], -x + z + y + pos[1]];

But how can I adjust this to match angles of 190 and 140?

EDIT: Found it for the X axis (thanks Dan):

x = effect("X Movement")("Slider");

a = 190;

y = -x*Math.tan(degreesToRadians(a));

value + [x,y]

But how to adjust this so Z has an angle of 140?

Got it:

pos = transform.position;

x = effect("X Movement")(1);

z = effect("Z Movement")(1);

y = effect("Y Movement")(1);

a1 = 190;

a2 = 40;

[x + z + pos[0], -x*Math.tan(degreesToRadians(a1)) + z*Math.tan(degreesToRadians(a2)) + y + pos[1]];

Thank you for sharing your solution!
