You need to use the OnPlayerSpawn callback, players that spawn or respawn will be passed through this function.

You could then use the SetSpawnInfo function or various others to achieve your goal (I believe the SetSpawnInfo is safer than the others but I personally haven't been using it much and haven't had any issues with setting position, skin etc seperately).
