    I present to you my...

    On Attack Template 1.30:
    a simple system that allows you do to some great things

    What does this do?

    In the absence of a better method for damage detection using GUI;

    This allows you leverage the event "a unit is attacked", and both efficiently and accurately, detect when the target takes damage, and deal effects to said unit.

    Sounds like fun no..??

    Ok then hurry up and try it out!!

    Version History:
    • 1.30 - Updated for 1.24 compatibility, removed dated CSData and CSSafety requirements, re-arranged and shorten code a bit, optimized trigger execution function, added theoretical destroytrigger() bug aversion configurable
    • 1.20b - Updated to CSData and CSSafety 15.0, added in a new demo ability to showcase usage of the On_Attack_Template_Function call, Demo 3 updated slightly, few minor readme/documentation errors updated
    • 1.2 - Ported to vJASS, slightly updated readme, removed demo 4 ability from test map
    • 1.1 - Added greater functionality
    • 1.0 - Initial Release

    could please explain in detail about this on attack system?

    i don't really get the point of having it o.o"

    So that you don't have to be like DotA and use orb effect spots that block other on-attack effects.

    normally to do a spell like this is GUI, you would go off the event a unit is attacked

    this can be played with and you cna actually pause ur unit and make it attack real fast, so as to never actually attack, but get the effects, this is an abuse

    what this allows you to do is, detect whe na unit is attack, go through ur conditions, all in GUI, and if they match up, call this with an ability to be cast

    as you can see fro mthe range char. I put into the map, it waits until the damage is done to do the effects, else the spells would be casted before even the projectile left the attacker

    how is this better even more so?

    well to stop this abuse, in DoTA, for ex., with Spirit Breakers Greater Bash

    the main triger is disabled once it fires, and not reenabled unitl after the slide is over

    so not only can there not be multiple slides at the same tiem for different spirit breakers, but it there can only be one slide ever in the game, and one that is over a new one can happen

    pretty shitty if you ask me

    i have thought of ways to further improve this and make it be able to do more things

    i will add major updates and a better readme next week when I have the time to

    until then, more comments please :)

    I don't see what's so special about this though... It's just saying if someone gets attacked and the 30% chance happened, then cast the ability...

    The 'unit is attacked' event fires on the attack initialization. AKA it allows you to spam the 'stop' button to spam a triggered spell.
    If you use a damage detection trigger w/o proper coding you can make things fire on like, spell casts. Usually not a big deal, but undesireable.

    This is a rather good system.

    basically it allows what all JASS users do for their maps, for the most part, since it is better, to be used by GUI ppl as well

    do this for me

    in the demo map, make a trigger on attack to cast an ability for the ranged hero

    and look at the difference there

    **UPDATED, now with much more functionality and a better read me

    Blimmin Brilliant!

    Although, it is sorta hard to edit because I suck at Jass, but that's my fault :p

    That frost spell is one of the coolest spells I have ever seen.

    No lag, no ugliness, just perfect. (+Rep)

    I have a question.
    What would the difference be between using a system like this compared to a system where you have a trigger A that adds all units who enters playable map area (triggering unit takes damage) to trigger B where the actual effect is?

    not sure what you mean there...I guess however that that would leak a good bit more though, and be slower

    What I mean:

    Detect Trigger:
    function Trig_addevent_Actions takes nothing returns nothing
        call TriggerRegisterUnitEvent( gg_trg_Spell_A, GetTriggerUnit(), EVENT_UNIT_DAMAGED )
        call TriggerRegisterUnitEvent( gg_trg_Spell_B, GetTriggerUnit(), EVENT_UNIT_DAMAGED )
    function InitTrig_addevent takes nothing returns nothing
        set gg_trg_addevent = CreateTrigger(  )
        call TriggerRegisterEnterRectSimple( gg_trg_addevent, GetPlayableMapRect() )
        call TriggerAddAction( gg_trg_addevent, function Trig_addevent_Actions )
    Spell A:
    function Trig_Spell_A_Conditions takes nothing returns boolean
    return GetRandomInt(1,100)>80
    function Trig_Spell_A_Actions takes nothing returns nothing
        //Spell actions
    function InitTrig_Spell_A takes nothing returns nothing
        set gg_trg_Spell_A = CreateTrigger(  )
        call TriggerAddCondition( gg_trg_Spell_A, Condition( function Trig_Spell_A_Conditions ) )
        call TriggerAddAction( gg_trg_Spell_A, function Trig_Spell_A_Actions )
    Spell B:
    function Trig_Spell_B_Conditions takes nothing returns boolean
    return GetRandomInt(1,100)>60
    function Trig_Spell_B_Actions takes nothing returns nothing
        //Spell actions
    function InitTrig_Spell_B takes nothing returns nothing
        set gg_trg_Spell_B = CreateTrigger(  )
        call TriggerAddCondition( gg_trg_Spell_B, Condition( function Trig_Spell_B_Conditions ) )
        call TriggerAddAction( gg_trg_Spell_B, function Trig_Spell_B_Actions )
    Would this be slower and leak more?

    that is theoretically that optimal way to do it

    however, try and get a GUI user to make that work, and then you have issues

    System coded in GUI or JASS ?
    Mind post the code??

    I am having slow internet speed now...(At friends house for few days)
    So i might need to avoid all uneeded download

    Any chance to make this compattible with ABC?
    Or in General, make it vJass compattible? =)
