Random starting PC?

Hi, I'm trying to randomize the starting position of a PC player on a UMS training map. These are my triggers (see image).

Basically, I randomize TOP and BOT triggers in order to create one out of four possible outcomes. Then, if conditions are met, a Nexus and four probes are created on the northeast starting point (or one of the other three, the SS is just and example.

The third (actually, four) trigger is to prevent the base/probes from being created in the same position as the player base, which position is randomized with the Force's "Randomize Start Locations".

Sometimes the triggers create two bases, sometimes just one, sometimes the AI derps itself, and sometimes it seems to work (gets 2 Gateways, then 12 zealots and it attacks).

Any advise is welcomed. I'm pretty new at this :D.

We can't explain the universe, just describe it; and we don't know whether our theories are true, we just know they're not wrong. >Harald Lesch

First make all the triggers owned by the computer player.
Then the logic is simple. While the cpu player has no buildings randomize the position.
Then have 4 triggers to create buildings for each position. Only run it when there's no buildings at the position and the cpu (still) doesn't have buildings.
Make sure the defeat trigger is ABOVE these to prevent the computer from getting new buildings when he lost them all. ;) Since the building creation triggers are owned by the cpu they won't run anymore once it's defeated.

This way you only need 5 triggers total:

  • CPU Player
  • Conditions

  • Current Player brings at most 0 [any unit] to Anywhere
  • Actions

  • Randomize Switch Top
  • Randomize Switch Left
  • Preserve trigger

  • I renamed to switch just because I find it more logical that way. If Top is set the base will be created in the northern half of the map, if not southern half. If left is set it'll be west, otherwise east.

    Place NE

  • CPU Player
  • Conditions

  • Switch Top is set
  • Switch Left is cleared
  • All Players brings at most 0 [any unit] to Pos_NE
  • Current Player brings at most 0 [any unit] to Anywhere
  • Actions

  • [Create buildings]
  • [Run AI script]
  • Preserve trigger

  • repeat 3 times:
    NW: Top is set; Left is set
    SE: Top is cleared; Left is cleared
    SW: Top is cleared; Left is set

    np. :)
    Actually, I just realized, don't preserve the place buildings triggers. It doesn't really matter, but it's more efficient.

    It worked wonderfully :D

    Now I'm trying to randomize race, this is my take (ignore FORCE 1 triggers, they came with the original MacroAlone training map). Basically, I tried using switches an a Death Counter to randomize it, but I couldn't manage to make it work every time:

    Actually, I found this trigger that messes up my death counter randomization, hehe
