You can use random() function.

For example:

Код:

new RandomSpawns[][]=
{ SetPlayerPos(playerid,x,y,z.....);//first spawn place
  SetPlayerPos(playerid,x,y,z.....);//second spawn place
  .
  .
  .
  .
 }

Then OnPlayerSpawn or aywhere you want,

Код:

random("RandomSpawns");

There maybe some errors above
You get the idea though don't you
