Try update the version.
However, did you define it

pawn Код:

#define SetPlayerHoldingObject(%1,%2,%3,%4,%5,%6,%7,%8,%9) SetPlayerAttachedObject(%1,MAX_PLAYER_ATTACHED_OBJECTS-1,%2,%3,%4,%5,%6,%7,%8,%9)
#define StopPlayerHoldingObject(%1) RemovePlayerAttachedObject(%1,MAX_PLAYER_ATTACHED_OBJECTS-1)
#define IsPlayerHoldingObject(%1) IsPlayerAttachedObjectSlotUsed(%1,MAX_PLAYER_ATTACHED_OBJECTS-1)
