Added the readme, but couldn't really think of anything to add to it apart from the parameters. Same goes with the advertisement, all it does is pick random position, people can use it to whatever they can think of. For example, I've made a defense mission where you can use parameters to pick enemy attack direction, distance, sector width etc.
Another one I made is one where you can train navigation (orienteering) by randomly placing control points which players need to find by using just map and compass. One use I've found for it is that if you need to move/place multiple objects/units to a position, you can just do random 360 for direction and something like 5-15 for distance. That way they will be placed near the position but without being right on top of each other (can injure units when moving a group). Simple, no need to start tinkering with +/- couple of meters for each x and y.
The script isn't anything fancy, I just needed random positions so I made this. Thought Id share it.
