I'm trying to implement the ABuff System in my map. However, because I'm new to vJass, I still cannot understand enough of it and I don't know how to fix this issue that everytime a unit enters the game (spawned, trained, built), it won't be Indexed becaused it is a Filtered Unit (even though Anitarf provided a comment on his System to help us understand it). I hope someone can help me.
Edit: I uploaded the ABuff System.w3x, because there might be something that is causing the error. PLEASE HELP. I desperately need your help right now!
JASS:
library AutoIndex
//===========================================================================
// Information:
//==============
//
// AutoIndex is a very simple script to utilize. Just call GetUnitId(unit)
// to get get the unique value assigned to a particular unit. The GetUnitId
// function is extremely fast because it inlines directly to a GetUnitUserData
// call. AutoIndex automatically assigns an ID to each unit as it enters the
// map, and instantly frees that ID as the unit leaves the map. Detection of
// leaving units is accomplished in constant time without a periodic scan.
//
// AutoIndex uses UnitUserData by default. If something else in your map
// would conflict with that, you can set the UseUnitUserData configuration
// constant to false, and a hashtable will be used instead. Note that hash-
// tables are about 60% slower.
//
// If you turn on debug mode, AutoIndex will be able to display several
// helpful error messages. The following issues will be detected:
// -Passing a removed or decayed unit to GetUnitId
// -Code outside of AutoIndex has overwritten a unit's UserData value.
// -GetUnitId was used on a filtered unit (a unit you don't want indexed).
//
// AutoIndex provides events upon indexing or deindexing units. This
// effectively allows you to notice when units enter or leave the game. Also
// included are the AutoData, AutoCreate, and AutoDestroy modules, which allow
// you to fully utilize AutoIndex's enter/leave detection capabilities in
// conjunction with your structs.
//
//===========================================================================
// How to install AutoIndex:
//===========================
//
// 1.) Copy and paste this script into your map.
// 2.) Save it to allow the ObjectMerger macro to generate the "Leave Detect"
// ability for you. Close and re-open the map. After that, disable the macro
// to prevent the delay while saving.
//
//===========================================================================
// How to use AutoIndex:
//=======================
//
// So you can get a unique integer for each unit, but how do you use that to
// attach data to a unit? GetUnitId will always return a number in the range of
// 1-8190. This means it can be used as an array index, as demonstrated below:
/*
globals
integer array IntegerData
real array RealData
SomeStruct array SomeStructData
englobals
function Example takes nothing returns nothing
local unit u = CreateUnit(Player(0), 'hpea', 0., 0., 0.)
local integer id = GetUnitId(u)
//You now have a unique index for the unit, so you can
//attach or retrieve data about the unit using arrays.
set IntegerData[id] = 5
set RealData[id] = 25.0
set SomeStructData[id] = SomeStruct.create()
//If you have access to the same unit in another function, you can
//retrieve the data by using GetUnitId() and reading the arrays.
endfunction
*/
// The UnitFilter function in the configuration section is provided so that
// you can make AutoIndex completely ignore certain unit-types. Ignored units
// won't be indexed or fire indexed/deindexed events. You may want to filter out
// dummy casters or system-private units, especially ones that use UnitUserData
// internally. xe dummy units are automatically filtered.
//
//===========================================================================
// How to use OnUnitIndexed / OnUnitDeindexed:
//=============================================
//
// AutoIndex will fire the OnUnitIndexed event when a unit enters the map,
// and the OnUnitDeindexed event when a unit leaves the map. Functions used
// as events must take a unit and return nothing. An example is given below:
/*
function UnitEntersMap takes unit u returns nothing
call BJDebugMsg(GetUnitName(u)+" with ID "+I2S(GetUnitId(u))+" entered the map.")
endfunction //Using GetUnitId() during Indexed events works fine...
function UnitLeavesMap takes unit u returns nothing
call BJDebugMsg(GetUnitName(u)+" with ID "+I2S(GetUnitId(u))+" left the map.")
endfunction //So does using GetUnitId() during Deindexed events.
function Init takes nothing returns nothing
call OnUnitIndexed(UnitEntersMap)
call OnUnitDeindexed(UnitLeavesMap)
endfunction
*/
// If you call OnUnitIndexed during map initialization, every existing
// unit will be considered as entering the map. This saves you from the need
// to manually enumerate preplaced units (or units created by initialization
// code that ran before OnUnitIndexed was called).
//
// OnUnitDeindexed runs while a unit still exists, which means you can
// still do things such as destroy special effects attached to the unit.
// The unit will cease to exist immediately after the event is over.
//
//===========================================================================
// AutoIndex API:
//================
//
// GetUnitId(unit) -> integer
// This function returns a unique ID in the range of 1-8190 for the
// specified unit. Returns 0 if a null unit was passed. This function
// inlines directly to GetUnitUserData or LoadInteger if debug mode
// is disabled. If debug mode is enabled, this function will print
// an error message when passed a decayed or filtered unit.
//
// IsUnitIndexed(unit) -> boolean
// This function returns a boolean indicating whether the specified
// unit has been indexed. The only time this will return false is
// for units you have filtered using the UnitFilter function, or
// for xe dummy units. You can use this function to easily detect
// dummy units and avoid performing certain actions on them.
//
// OnUnitIndexed(IndexFunc)
// This function accepts an IndexFunc, which must take a unit and
// return nothing. The IndexFunc will be fired instantly whenever
// a unit enters the map. You may use GetUnitId on the unit. When
// you call this function during map initialization, every existing
// unit will be considered as entering the map.
//
// OnUnitDeindexed(IndexFunc)
// Same as above, but runs whenever a unit is leaving the map. When
// this event runs, the unit still exists, but it will cease to exist
// as soon as the event ends. You may use GetUnitId on the unit.
//
//===========================================================================
// How to use AutoData:
//======================
//
// The AutoData module allows you to associate one or more instances
// of the implementing struct with units, as well as iterate through all
// of the instances associated with each unit.
//
// This association is accomplished through the "me" instance member,
// which the module will place in the implementing struct. Whichever unit
// you assign to "me" becomes the owner of that instance. You may change
// ownership by reassigning "me" to another unit at any time, or you may
// make the instance unowned by assigning "me" to null.
//
// AutoData implements the static method operator [] in your struct
// to allow you to access instances from their owning units. For example,
// you may type: local StructName s = StructName[u]. If u has been set
// to own an instance of StructName, s will be set to that instance.
//
// So, what happens if you assign the same owning unit to multiple
// instances? You may use 2D array syntax to access instances assigned to
// the same unit: local StructName s = StructName[u][n], where u is the
// owning unit, and n is the index beginning with 0 for each unit. You
// can access the size of a unit's instance list (i.e. the number of
// instances belonging to the unit) by using the .size instance member.
/*
struct Example
implement AutoData
static method create takes unit u returns Example
local Example this = allocate()
set me = u //Assigning the "me" member from AutoData.
return this
endmethod
endstruct
function Test takes nothing returns nothing
local unit u = CreateUnit(Player(0), 'hpea', 0., 0., 0.)
local Example e1 = Example.create(u)
local Example e2 = Example.create(u)
local Example e3 = Example.create(u)
local Example e
call BJDebugMsg(I2S(Example[u].size)) //Prints 3 because u owns e1, e2, and e3.
set e = Example[u][GetRandomInt(0, Example[u].size - 1)] //Random instance belonging to u.
set e = Example[u] //This is the fastest way to iterate the instances belonging
loop //to a specific unit, starting with the first instance.
exitwhen e == 0 //e will be assigned to 0 when no instances remain.
call BJDebugMsg(I2S(e)) //Prints the values of e1, e2, e3.
set e = e[e.index + 1] //"e.index" refers to the e's position in u's instance list.
endloop //Thus, index + 1 is next, and index - 1 is previous.
endfunction //This trick allows you to avoid a local counter.
*/
// AutoData restrictions:
// -You may not implement AutoData in any struct which has already
// declared static or non-static method operator [].
// -AutoData will conflict with anything named "me", "size", or
// "index" in the implementing struct.
// -AutoData may not be implemented in structs that extend array.
// -You may not declare your own destroy method. (This restriction
// can be dropped as soon as JassHelper supports module onDestroy).
//
// AutoData information:
// -You do not need to null the "me" member when destroying an
// instance. That is done for you automatically during destroy().
// (But if you use deallocate(), you must null "me" manually.)
// -StructName[u] and StructName[u][0] refer to the same instance,
// which is the first instance that was associated with unit u.
// -StructName[u][StructName[u].size - 1] refers to the instance that
// was most recently associated with unit u.
// -Instances keep their relative order in the list when one is removed.
//
//===========================================================================
// How to use AutoCreate:
//=======================
//
// The AutoCreate module allows you to automatically create instances
// of the implementing struct for units as they enter the game. AutoCreate
// automatically implements AutoData into your struct. Any time an instance
// is automatically created for a unit, that instance's "me" member will be
// assigned to the entering unit.
//
// AutoCreate restrictions:
// -All of the same restrictions as AutoData.
// -If your struct's allocate() method takes parameters (i.e. the parent
// type's create method takes parameters), you must declare a create
// method and pass those extra parameters to allocate yourself.
//
// AutoCreate information:
// -You may optionally declare the createFilter method, which specifies
// which units should recieve an instance as they enter the game. If
// you do not declare it, all entering units will recieve an instance.
// -You may optionally declare the onCreate method, which will run when
// AutoCreate automatically creates an instance. (This is just a stand-
// in until JassHelper supports the onCreate method.)
// -You may declare your own create method, but it must take a single
// unit parameter (the entering unit) if you do so.
/*
struct Example
private static method createFilter takes unit u returns boolean
return GetUnitTypeId(u) == 'hfoo' //Created only for Footmen.
endmethod
private method onCreate takes nothing returns nothing
call BJDebugMsg(GetUnitName(me)+" entered the game!")
endmethod
implement AutoCreate
endstruct
*/
//===========================================================================
// How to use AutoDestroy:
//=========================
//
// The AutoDestroy module allows you to automatically destroy instances
// of the implementing struct when their "me" unit leaves the game. AutoDestroy
// automatically implements AutoData into your struct. You must assign a unit
// to the "me" member of an instance for this module to have any effect.
//
// AutoDestroy restrictions:
// -All of the same restrictions as AutoData.
//
// AutoDestroy information:
// -If you also implement AutoCreate in the same struct, remember that it
// assigns the "me" unit automatically. That means you can have fully
// automatic creation and destruction.
/*
struct Example
static method create takes unit u returns Example
local Example this = allocate()
set me = u //You should assign a unit to "me",
return this //otherwise AutoDestroy does nothing.
endmethod //Not necessary if using AutoCreate.
private method onDestroy takes nothing returns nothing
call BJDebugMsg(GetUnitName(me)+" left the game!")
endmethod

// Configuration:
//================

//This is set to true by default so that GetUnitId() will ALWAYS work.
//If if this is set to false, GetUnitId() may fail to work in a very
//rare circumstance: creating a unit that has a default-on autocast

private constant boolean AutoDataFastMode = true
