On top of script:

Код:

#define PRESSED(%0) \
	(((newkeys & (%0)) == (%0)) && ((oldkeys & (%0)) != (%0)))

Now:

Код:

public OnPlayerConnect(playerid)
{
	SetPVarInt(playerid,"Carrying",0);
	return 1;
}

public OnPlayerDisconnect(playerid, reason)
{
	if(GetPVarInt(playerid,"Carrying")==1) { SetPVarInt(playerid,"Carrying",0); }
	return 1;
}

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
	if(PRESSED(KEY_YES)) // ' Y ' Key
	{
	    if(GetPVarInt(playerid,"Carrying")==0) { SetPlayerSpecialAction(playerid, 25); SetPVarInt(playerid,"Carrying",1); }
	}
	else if(PRESSED(KEY_NO)) // ' N ' Key
	{
	    if(GetPVarInt(playerid,"Carrying")==1) { SetPlayerSpecialAction(playerid, 0); SetPVarInt(playerid,"Carrying",0); }
	}
	return 1;
}

Hope you understand.
