Hi againt!

. How I do to each player receives his main building (command center, nexus or hatchery) of the race selected. And their scv, drone or probe.
None.
Set to melee or top v bottom mode when u host map.
None.
no no... it's for UMS map.
None.
set the players race to user select.
None.
It's for a UMS map like Desert Strike... each player selec his race... I can't pre-set their choices...
None.

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
Keep in mind, that when a player is set to user select (comps too, btw.) none of the preplaced units get created for him. He's getting ONLY 4 workers and a main building of the race he chose.
All other units have to be created with triggers afterwards.
Thanks... but I discover that in test... jejeje
None.

Oh I just realized that there's another way to have "preplaced" units for a 'user select' player.
Place the units in the editor for another player, for example P9 and then give all units from P9 to the user select player. Useful for stacking buildings or illegal placements.
