From SA-MP Wiki
This function can be used to change the spawn information of a specific player. It allows you to automatically set someone's spawn weapons, their team, skin and spawn position, normally used in case of minigames or automatic-spawn systems. This function is more crash-safe then using SetPlayerSkin in OnPlayerSpawn and/or OnPlayerRequestClass, even though this has been fixed in 0.2.
