Two new versions/types [modifications of the original and the IPool version] coming in maybe a week or so, depending on how much time I could spare...

Item Drop System 1.20
by Adiktuz
----------------------------------------------------------------------------------
Description:
A system that would allow the dynamic creation of item drop lists per UnitTypeId or
per specific unit and handle the process of item dropping from killing monsters.
----------------------------------------------------------------------------------
Features:
-You can add lots of items to the drop list of a unit ( max is defined by a global)*
-You can dynamically specify the number of items that a single unit can drop upon death*
-You can also add drop chance bonuses to a unit (direct or multiplier)
-You can dynamically add or remove items from drop list of units*
*can be both based on UnitTypeId or per specific unit
----------------------------------------------------------------------------------
Requirements:
- Wc3:TFT 1.24e
- NewGenWE
- JassHelper (at least 0.A.2.A)
- Ability to follow instructions
----------------------------------------------------------------------------------
How to import:
- Create a new trigger on your map, then convert to custom sript
- Replace anything inside that trigger with the contents of this library
----------------------------------------------------------------------------------
How to use the ItemDropSystem (general , UnitTypeId based):
1) Initialize UnitTypeIds to use this system
- use this call function to initialize each UnitTypeId that will use this system
- call ItemDrop.InitUnit(integer UnitRawCode, integer DropItemsMax)
*UnitRawCode is the rawcode of the unit
*DropItemsMax is the maximum number of items from the pool that a dying unit of that
UnitTypeId can drop
2) Add items to the drop list of a UnitTypeId
- use this call function to add items
- call ItemDrop.AddItem(integer UnitRawCode, integer ItemRawCode, real Chance)
*UnitRawCode is the rawcode of the unit where you want to add the item
*ItemRawCode is the rawcode of the item
*Chance is the percent chance to drop the item (from 0.01 up to 100.00)
-Note: to avoid too much stress on computers, don't add so many items to a UnitTypeId
3) To remove items from the drop list of a UnitTypeId
- use this call function to remove items
call ItemDrop.RemoveItems(integer UnitRawCode, integer ItemRawCode)
*UnitRawCode is the rawcode of the unit where you want to add the item
*ItemRawCode is the rawcode of the item
4) To modify the max number of items that a single unit of a certain type can drop
- use this call function
call ItemDrop.ChangeDropMax(intger UnitRawCode, integer Max)
*UnitRawCode is the rawcode of the unit where you want to modify the drop max
*integer Max is the new maximum amount of items that a single unit of that type can drop
upon death
5) To unregister a UnitTypeId
call ItemDrop.Unregister(integer rawcode)
*rawcode is the rawcode/UnitTypeId of the unit you want to unregister
----------------------------------------------------------------------------------
How to use the ItemDropSystem (specific):
1) Initialize the Unit to use this system
- use this call function to initialize the unit that will use this system
- call ItemDrop.InitUnitSpecific(unit u, integer DropItemsMax, boolean ProcessBoth)
*u is the unit
*DropItemsMax is the maximum number of items from the pool that the dying unit can drop
*ProcessBoth checks if the system will process both the specific and general droplist for the unit
if false, the system will only process the specific drop list
2) Add items to the drop list of a unit
- use this call function to add items
- call ItemDrop.AddItemSpecific(unit u, integer ItemRawCode, real Chance)
*u is the unit where you want to add the item
*ItemRawCode is the rawcode of the item
*Chance is the percent chance to drop the item (from 0.01 up to 100.00)
-Note: to avoid too much stress on computers, don't add so many items to a UnitTypeId
3) To remove items from the drop list of a unit
- use this call function to remove items
call ItemDrop.RemoveItemSpecific(integer UnitRawCode, integer ItemRawCode)
*u is the unit where you want to add the item
*ItemRawCode is the rawcode of the item
4) To modify the max number of items that a unit can drop upon death
- use this call function
call ItemDrop.ChangeDropMaxSpecific(unit u, integer Max)
*u is the unit whom you want to modify the drop max
*integer Max is the new maximum amount of items that a single unit of that type can drop
upon death
5) To unregister a unit
call ItemDrop.UnregisterSpecific(unit u)
*u is the unit you want to unregister
----------------------------------------------------------------------------------
If you want to force a drop process outside of unit death event use this
call ItemDrop.ForceProcessDrop(unit dying, boolean IsSpecific, unit killer)

Item Drop System 1.20 (Pool Version)
by Adiktuz
----------------------------------------------------------------------------------
Description:
A system that would allow the dynamic creation of item pools per UnitTypeId or
per specific unit and handle the process of item dropping from killing monsters.
This version is for creating an item pool for each unit in which the drop rates
of each item in a pool is dependent on each other.
In this version, whether an item will be dropped or not is determined per unit
or unit-type, and then the item that will be dropped will depend on the weight of
each item in the poolversus the whole pool. The drop chance of an item is equal to
its weight over the total weight of the item pool.
Example Scenario:
-I registered crabs to have a drop chance of 15%
-Then I registered 3 items, each having a weight of 1
-Then I registered another item having a weight of 3
-Now the total weight would be 6
-Now on the case that a crab dies, a number will be randomized
from 0.00-100, if it falls under or equal to 15, that would mean that
an item should be dropped, else no item will be dropped.
-Now to get which item will be dropped from the crab's item pool, it will be
randomized based on its weight relative to the total
-that would mean that the 3 items having a weight of 1, each has a 1/6 chance
of dropping while the fourth item which has a weight of 3 has a chance of
3/6 or 50% chance that it would be the item which will be dropped.
----------------------------------------------------------------------------------
Features:
-You can add lots of items to the drop list of a unit
-You can also add drop chance bonuses to a unit (direct or multiplier)
-You can dynamically add or remove items from drop list of units*
*can be both based on UnitTypeId or per specific unit
----------------------------------------------------------------------------------
Requirements:
- Wc3:TFT 1.24e
- NewGenWE
- JassHelper (at least 0.A.2.A)
- Table and IPool by Bribe
- Ability to follow instructions
----------------------------------------------------------------------------------
How to import:
- Create a new trigger on your map, then convert to custom sript
- Replace anything inside that trigger with the contents of this library
----------------------------------------------------------------------------------
How to use: StructName = ItemDropPool
General
static method InitUnit takes integer UnitRawCode, real chance, integer amount
-> registers the UnitRawCode into the system and sets its chance of dropping
an item to real chance
-> amount is the number of items that can be dropped at a time
static method AddItem takes integer UnitRawCode, integer ItemRawCode, integer weight, integer amount

Item Drop System Multi Table 1.20 (Pool Version)
by Adiktuz
----------------------------------------------------------------------------------
Description:
A system that would allow the dynamic addition/removal of Item pools per UnitTypeId or
per specific unit and handle the process of item dropping from killing monsters.
Utilizes the IPool for creation/modification of item pools
----------------------------------------------------------------------------------
Features:
-You can add lots item pools to a unit
-You can dynamically add or remove item pools from units
----------------------------------------------------------------------------------
Requirements:
- Wc3:TFT 1.24e
- NewGenWE
- JassHelper (at least 0.A.2.A)
- Table and IPool by Bribe
- Ability to follow instructions
----------------------------------------------------------------------------------
How to import:
- Create a new trigger on your map, then convert to custom sript
- Replace anything inside that trigger with the contents of this library
----------------------------------------------------------------------------------
How to use: StructName = ItemDropPoolMT
General
static method InitUnit takes integer UnitRawCode, real chance, integer amount
-> registers the UnitRawCode into the system and sets its chance of dropping
an item to real chance
-> amount is the number of items that can be dropped at a time
static method AddPool takes integer UnitRawCode, IPool dtable, integer weight
-> adds the item pool to the pools used by UnitRawCode
-> chance of using this item pool upon a successful drop roll is equal to the
value of weight over the total weight of all registered item pools for that UnitRawCode
static method RemovePool takes integer UnitRawCode, IPool dtable
-> removes the specified item pool from those used by the UnitRawCode
static method Unregister takes integer rawcode returns nothing
->unregisters the rawcode from the system
Specific
static method InitUnitSpecific takes unit u, boolean ProcessBoth, real chance, integer amount returns nothing
-> registers a specific unit to the system
-> if ProcessBoth is true, the system would process the ItemPool registered to this
unit upon death, and also the itempool registered to the rawcode of this unit,
which if both are present, will lead to 2 item drops if this unit dies and
the roll chance falls within this unit's range
-> integer amount is the amount of items that the unit can drop upon death
static method AddItemSpecific takes unit u, IPool dtable, integer weight
-> adds the item pool to those used by the specific unit
static method RemovePoolSpecific takes unit u, IPool dtable
-> removes the item pool to those used by the specific unit
static method UnregisterSpecific takes unit u returns nothing
-> unregisters the specific unit from the pool
----------------------------------------------------------------------------------
If you want to force a drop process outside of unit death event use this
call ItemDropPool.ForceProcessDrop(unit dying, boolean IsSpecific, unit killer)

Item Drop System 1.20 (Destructable Version)
by Adiktuz
----------------------------------------------------------------------------------
-Works almost the same as the original Pool version but for destructables.
-Also, you need to manually set when the drop is processed
-for most of the functions here, when it takes the unitrawcode as parameter, its just replaced with
the destructable raw code while if it takes a unit as parameter, its just replaced with a destructable
example:
call ItemDropPoolDest.InitDest(integer DestRawCode, real chance)
call ItemDropPoolDest.InitDestSpecific(destructable u, boolean ProcessBoth, real chance)
To call for processing of a drop: (look at the sample trigger for better understanding)
call ItemDropPoolDest.ForceProcessDrop(destructable u, boolean IsSpecific, unit killer)
To clear the drop allocated to a destructable:
call ItemDropPoolDest.UnregisterSpecific(destructable u)
call ItemDropPoolDest.Unregister(integer DestRawCode)
Functions list:
call ItemDropPoolDest.InitDest(integer DestRawCode, real chance, integer amount)
call ItemDropPoolDest.InitDestSpecific(destructable u, boolean ProcessBoth, real chance, integer amount)
call ItemDropPoolDest.ForceProcessDrop(destructable u, boolean IsSpecific, unit killer)
call ItemDropPoolDest.AddItem(integer DestRawCode, integer ItemRawCode, integer weight)
call ItemDropPoolDest.AddItemSpecific(destructable u, integer ItemRawCode, integer weight)
call ItemDropPoolDest.RemoveItems(integer DestRawCode, integer ItemRawCode)
call ItemDropPoolDest.RemoveItemSpecific(destructable u, integer ItemRawCode)
call ItemDropPoolDest.UnregisterSpecific(destructable u)
call ItemDropPoolDest.Unregister(integer DestRawCode)
It would also be better if you will unregister specific drops allocated to a destructable
when it dies.

Changelog
JASS:
/*
----------------------------------------------------------------------------------
Version 1.10
-Saved the instance index into a hashtable
-replaced the Get intances with Hashtable function calls
-Added the functionality to use the IDS for specific units
----------------------------------------------------------------------------------
Version 1.11
-removed unnecessary variables
----------------------------------------------------------------------------------
Version 1.12
-it now destroys the struct instance for specific unit item pools when the unit dies
----------------------------------------------------------------------------------
Version 1.13
-changed the debug messages into static ifs
-renamed the struct to IDS_Adik
-removed the local boolean used to exit the drop loop
-fixed errors on the How To Use
----------------------------------------------------------------------------------
Version 1.13b
-fixed a flaw which reduces the chances of having an item drop (by making the loop run through an unused index)
Note: The code in the map might actually say 1.13 or 1.12... ignore it...
----------------------------------------------------------------------------------
Version 1.13c
-added Unregister methods. I'm not sure if it would be totally useful though, but added it anyway.
----------------------------------------------------------------------------------
Version 1.14
-optimized the code, removed unnecessary things
-separated the BonusChance functions into another library
-created another version which uses IPool (read code for details)
----------------------------------------------------------------------------------
Version 1.14b
-some minor optimizations as pointed out by Magtheridon96
----------------------------------------------------------------------------------
Version 1.14c
-changed the struct names (just use ctrl+H to change them on your codes which uses this system)
-Made it use RegisterPlayerEvent (by Magtheridon)
-Removed the hashtables and used Tables instead (3 tables per System as I realized that one of the booleans I save on the hashtable is unnecessary)
----------------------------------------------------------------------------------
Version 1.14d
-removed the boolean SHOW_ERROR and used DEBUG_MODE instead
-also fixed the internal version number of the ItemDropSystem
-Removed the InitHashtable call from the Pool version and updated the code on the description
----------------------------------------------------------------------------------
Version 1.15
-added functions for forcing the drop process outside of death events for the unit drops
-added a library for processing drops for destructable (pool version only)
-fixed a flaw on the bonuschance library which causes the drop chance to be 0.0 if the killing unit is not registered in the bonuschance library
----------------------------------------------------------------------------------
Version 1.20
-Added a multi-table versions
*This update has actually been long done on my comp, just forgot to upload it.
*/Why have I made it?
JASS:
/*
well, I was thinking of a new system to make and then this idea got to my head. Then I
browsed thru the spells section looking if there is already one but the ones which showed
up on the search were unflexible so I decided to do it... ^_^
I think this could be really useful for maps especially RPGs and the like...

Used this resource on my project and this works as I expected and I'm glad that I have full control of the drops and it's stuffs by just a simple set-up.
+rep for this awesome work.

Glad to know that there are people using this
