[Help] Player Random Spawn

Hello

How to create a random player spawn in a specific map please ?

Thanks if you tell me how to :D

if(loadout.GameMapId == 1 || loadout.GameMapId != ginfo_.mapId || loadout.Alive == 2)
{
GetSpawnPositionNewPlayer(loadout.GamePos, pos, dir);
pos->x += u_GetRandom(10, 120);
pos->z += u_GetRandom(10, 120);
return;
}

I spawn out of map (i have base and neutral spawn)
