SetPlayerAttachedObject dont return the id of created object (Return Values: 1 on success, 0 on failure.) , so you should use

PHP код:

GetPlayerPos(playerid, lnx_pLoc[0], lnx_pLoc[1], lnx_pLoc[2]); 


instead of

PHP код:

GetObjectPos(PetObject[playerid], lnx_pLoc[0], lnx_pLoc[1], lnx_pLoc[2]); 


Note: The created 3DText will not attach to player and will be placed at player position.
