Basic list of angles?

For emitters or other items that you want to emit at a controlled direction - is there a way to calculate the X/Y/Z values needed? Even if that needs to be done on a real calculator or computer and entered manually I don’t mind.

Eg keeping x/y 0 and rotating z every 30 degrees around from 0 to 360. Then same for x and y?

  It's pretty basic trigonometry, just use a sine and cosine. If you want 0 degrees to point in +X and 90 degrees to point in +Y etc, the values are x = cos(angle) and y = sin(angle). Make sure your phone or PC's calculator is set to Degrees mode instead of Radians.

  Thanks. How about Z? I’m getting confused because I was hoping it’d just be simple like -1 to +1 per axis but if I put sliders onto the inputs it doesn’t work like that, I have to change multiple axes to get eg Z all the way around
