random encouter positioning

[Ghoul [BB]]

in worldmap.txt there are some types of positioning for NPC, like
straight_line
double_line
wedge
cone
huddle
Surrounding
I am curious about how to make a new ones or modify the current ones.
is there any information about it?

Maybe check the source code from Fallout 2 Reference Edition?

According to this, it's hardcoded into the engine.
I am curious about "huddle" positioning. Here could be maximun 0f 6 critters. And for some reason not possible to make more. Instead of wedge, cone, surrounding options.
