Actually, i wrote on the top under the includes "new Float:XX,Float:Y,Float:Z;"
Then OnPlayerConnect, i wrote "SetPlayerPos(playerid,Float:XX,Float:Y,Float: Z);"
then onPlayerDisconnect i wrote "GetPlayerPos(playerid,Float:XX,Float:Y,Float: Z);

Theres no error or warning but it doesn't works

Its single X not double i just added double because then it will be a funny face
