A member from this community called for a tutorial with this so I made this little tutorial with several functions. These functions can be applied during an event to lock assembly automatic any items Self pickup because stiim with all that many players join a private server when an event such as a break Metin and get xx chests, and players use most illegal software in order to collect as many chests or any item.

Command in game for disable/activate:

/e enable_block_table_pickup 1 -> Activate

/e enable_block_table_pickup 0 -> Disable

Spoiler

- [ File: /Src/common/service.h ]

#define __ENABLE_BLOCK_PICKUP__ // Enables blocking of special items that can not be collected
#define __ENABLE_BLOCK_PICKUP__WARNING "[Block PickUp] You cannot collect this item when event is active!"

- [ File: /Src/common/length.h ]

enum TablePickupItem
{
	BLOCK_VNUM_0 = 50011,
	BLOCK_VNUM_1 = 50124,
	BLOCK_VNUM_2 = 50125,
	BLOCK_VNUM_3 = 50126,
	BLOCK_VNUM_4 = 50127,
	BLOCK_VNUM_5 = 50128,
	BLOCK_VNUM_6 = 50129,
	BLOCK_VNUM_7 = 50130,
	BLOCK_VNUM_8 = 50131,
	BLOCK_VNUM_9 = 50132,
	BLOCK_VNUM_10 = 50133,
};
