It is and you should declare it as a global array then.

pawn Код:

// global (under #define):
new Text3D: IAM[MAX_PLAYERS] = {INVALID_3DTEXT_ID, ...};

in OnPlayerConnect:

pawn Код:

IAM[playerid] = INVALID_3DTEXT_ID;

To where it creates the 3d label:

pawn Код:

IAM[playerid] = Create3DTextLabel("Administrator on duty!\n*Do not Disturb*",0xF600F6FF,30.0,40.0,50.0,40.0,0);
Attach3DTextLabelToPlayer(IAM[playerid],playerid,0.0,0.0,0.5);

To where it destroys it:

pawn Код:

Delete3DTextLabel(IAM[playerid]);
