Need help with skill_require_db for spell.

[anacondaq]

Hi, i want to make next thing.

 

As we all know we have at db/pre or re/skill_require_db.txt

With next structure:

SkillID,HPCost,MaxHPTrigger,SPCost,HPRateCost,SPRateCost,ZenyCost,RequiredWeapons,RequiredAmmoTypes,RequiredAmmoAmount,RequiredState,RequiredStatuses,SpiritSphereCost,RequiredItemID1,RequiredItemAmount1,RequiredItemID2,RequiredItemAmount2,RequiredItemID3,RequiredItemAmount3,RequiredItemID4,RequiredItemAmount4,RequiredItemID5,RequiredItemAmount5,RequiredItemID6,RequiredItemAmount6,RequiredItemID7,RequiredItemAmount7,RequiredItemID8,RequiredItemAmount8,RequiredItemID9,RequiredItemAmount9,RequiredItemID10,RequiredItemAmount10,RequiredEquipment

I need to modify sources & that db to next prototype:

 

Original:

289,0,0,1,0,0,0,99,0,0,none,0,0,715,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 //SA_DISPELL

Modified:

289,0,0,1,0,0,0,99,0,0,none,0,0,715:505:506,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0	 //SA_DISPELL

What i want to get by this edit:

 

1. IF player have itemID 715 (yellow gemstone) -> he can use spell and that item will be removed (like by default)
2. IF player DON'T have itemID 715 map-server will be looking for player inventory for next value after ":", the next value in this example 505. So, if player Don't have 715, but have 505 -> the skill will require this item for skill.
3. IF player don't have 715 or 505 in inventory -> server will looking for next item_id after ":", the next item is 506. So if player don't have 715 or 505 item in inventory (order is important) the skill will require and use 506 item id.
4. IF player don't have any item of that list (715, 505, 506) in inventory -> skill will fail.
5. Requirement Amount (715:505:506,1) is the same for all of this items.

 

In few words:

I want to make alternative require_db for spell in txt file which is divided by ":" (like weapon's (Spiral Pierce in renewal (it's required OR Spear or Sword))

 

 

I did found this function, and i'm get stucked.

interesting, but it might increase memory usage.

I'll try this
