I have a conditional boss, a crowd of units approaches him, I need to place them in a semi-circle, how can I find the direction of their position relative to the boss? or mb there are other options how to arrange them like that?

Answer 1

Head-on solution - 7th class of geometry.
We have a right-angled triangle, we have an angle (for example, we want to place them every 10 degrees), there is a hypotenuse (it's also the radius on which we want to place enemies).
You need to find the legs, knowing the angle and hypotenuse (they suggest that these are sine and cosine).

Answer 2

Equation of a circle as an option
