Simple Filter Sytem v1.01

**************************************************************************************
*************************Simple Filter System v1.01***********************************
**********************************************************************************
******************************By: Matrix****************************************
Pros:
1) Allow to create filters
2) Consists of 68 lines
3) Can be confugured up to 4 options
Cons:
1) Mb smb find it not very user friendly
====================================================================================
PURPOUSE OF SFS:
====================================================================================
* Simply create filters

* Currently supported alliance, visibility, unittype and aliveness

* These are the only 4 handle types I found that are in need
If you have the need for some other handle types please let me know
====================================================================================
Changelog v1.01
====================================================================================
1) Less size
2) Changed the way of setting filter
3) More Cleaner&Leakless code
====================================================================================
How to implant:
====================================================================================
The system is very easy. The only things you'll have to do to implement the system is to
copy the trigger "SFS" into your map
====================================================================================
Quick function index:
====================================================================================
__________________________________________________________________________________________|
Set Functions - these functions makes ur boolexpr
----------------------------------------------------------------------
function SetSFS takes player p, integer Enemy, integer Visibility, unittype u, integer OnlyThatUnit, integer Alive returns nothing

player p - the player (owner of caster); use null if not needed

integer Enemy - if you want group filter enemies of the player use True; Ally - use False;
if You don't want use this option use Null

integer Visibilty - If you wants group filter only visible units for player p use True; Only Non-Visible use False;
All - use Null

unittype u - the unittype u only (not) allowed to be in group

integer OnlyThatUnit - if You want filter group with only that unit-type use True; Except that unittype use False;
if You don't want use this option use Null

integer Alive - if You want to filter only alive units use True; only dead use False;
All - use Null

__________________________________________________________________________________|
Clear Function
----------------------------------------------------------------------
ClearFilter() // Use only after using filter
__________________________________________________________________________________________|
====================================================================================
How to use:
====================================================================================
* Lets assume you want to create some spell filter
You would do the following:

Example
1. call SetSFS(GetOwningPlayer(GetTriggerUnit()),True,True,null,Null,True)
2. call GroupEnumUnitsInRange(group,x,y,range,SFS)
3. call ClearFilter()
====================================================================================
SPECIAL THANKS TO:
====================================================================================
* PandaMine - AFS from which I did this sys
HOW TO IMPORT:
* Just create a trigger named SFS
* convert it to text and replace the whole trigger text with this one

==============================================================================
Hopefully this system will help you!

this is just a remix of Panda's AFS

Haven't tested this but looks pretty good!

This doesn't really matter, but for presentation's sake, shouldn't the description part be in

 tags, since you have it it JASS format?

I dont proud of this sys by the time coz it's not very user friendly and it's just a remix of Panda's Advanced Filter System.

Although I was thinking hard how to do it really SFS but it's a pitty boolean can't be null (only true or false0 otherwise this sys was much simpliest and faster.

I want change it a lot coz I was wondering about filters// they really annoys jassers&spellmakers

Ok np
