Put this the rest of your "new"

pawn Code:

new Float:RandomSpawns[4][3] = {
{1253.6213,368.9244,19.5614}, //Change if you wish to.
{1263.1244,369.7004,19.5547}, //Change if you wish to.
{1246.1509,368.8576,19.5547}, //Change if you wish to.
{1256.1157,364.1463,19.5614} //Change if you wish to.
};

Put this under OnPlayerCommandText.

pawn Code:

if(strcmp(cmdtext, "/rspawn", true) == 0) // Change if you wish to.
    {
    new rand = random(sizeof(RandomSpawns));
    SetPlayerPos(playerid, RandomSpawns[rand][0], RandomSpawns[rand][1], RandomSpawns[rand][2]);
}
