Create a semicircle

[MasterTrainer]

Er.

I want to create a semicircle of units that will always appear behind the caster. Apparently, doing ((facing of unit) - 180) just dies out when the caster faces 0 degrees. Doing (((real(integer A)) x (360/36))/2) just creates the semicircle towards the same angle every single time. I've tried different stuff with the (facing of unit) thing but nothing really works.

How is this done?

Thanks in advance.

It should be: (not tested, but I am fairly certain it'd work)
set start = (facing of unit - 180) - 90
loop 1-10
set loc1 = middlePoint
set loc2 = middile point offset x towards start + (integer a * 18)
endloop

18 should be replaced with 180 / end loop (10 in my case)

That -90 is a savior

Thanks for the help ^^^
