[Spell] LoL Kalista Rend: Stacking local variables on a unit per Attack

[Lysho]

So I want to make a hero ability similar to one that League of Legend's Kalista has.

Her ability is called Rend and has a passive effect as well as an activate effect. The passive effect is that her auto attacks store "spears" in the enemies that she strikes, with no limit on how many spears she can stack in them. If she does not attack the target again within several seconds, all the spears in them disappear. This passive does no inherent damage.

However, the active effect is that all enemies with at least 1 "spear" in them consume all the "spear" stacks they have to deal damage (increasing based on how many spears they have) as well as slowing them.

I want to make an ability similar to this, but my WC3 hero has a "passive" ability at level 1 that lets them start stacking these "spears" (in this case called "sins"). I want the hero to stack "Sins" in enemy units struck on each basic attack, stacking infinitely and stacking separately for each unit struck. And if a unit is not attacked within 5 seconds, they lose all the "Sins" stacked on them.

That's the trigger I'm stuck with right now because I have no idea where to begin in doing this. I tried making a boolean variable check true if the unit was attacked, and then after a 5 second wait, set the boolean to false. And then have a separate periodic event trigger (every 0.5 seconds) check all units that might have the boolean = false and to set their number of Sins to 0. But I don't know how to give each unit an individual counter for Sins. I am already using the trigger function Custom Value for something else and I'd rather not use that.

But I feel like my periodic trigger is very bad and will lag the crap out of the game and I don't even think it will work since i dont know how to make the boolean indepedent for each unit.

Please help??

You need a custom buff system.
My Effect Over Time (may be the only one that) works with normal buffs, but is quite heavy to work with it.
In any case, in that one, you can create your own buff and give it some parameters like "source", "duration" and even custom variables for example "sins"/"stacks".

You will have to catch the onDamage event for basic attacks (for which a damage detection system will do for now) and then apply the buff on the target with a 5 seconds duration... if the target didnt have the buff already.
If it does have the buff already, then you can increase the "sins"/"stacks" by 1.

In any case, whatever you are using "custom value of <unit>" for... remove it.
Download a unit indexer (which uses the custom values) and create an integer array.
The array will now contain the values of your data for your unit.
So:
"set MyIntegerArray[Custom value of Unit1] = 1"
"set MyIntegerArray[Custom value of Unit2] = 2"
"set MyIntegerArray[Custom value of Unit3] = 3"
You can not only have integers but any variables for each unit.

Ok I'll try your system to see if it works. It might take me some time to figure out but it seems really cool. Thanks!

You create 1 "instance" per unit struck. Each instance has a counter or timer which is set to expire in 5 seconds. Each instance also has a stack count starting at 1. Instances are mapped to units either with hashtable or custom value. If a unit is hit and has no instance then one is created for it. Each time a unit is hit and it already has an instance you then reset its timer to 5 seconds and increment stack count by 1. The buff graphics can be synchronized using the timer since it can be set to last forever and remove it after 5 seconds or if you refresh it constantly you can set it to last 7 odd seconds so that it flashes like all buffs that will expire shortly.

The stacks dont expire separately.
It is one buff with infinite stacks and when a stack is added, the timer resets.

Ah I knew this was going to be complicated for me... I made the variables and I tried basing it off the example of Magic Shield from your system since it seemed to resemble what I'm aiming for best... But this is what I got and I can't even enable the trigger without getting error messages and I just have no idea what I am doing. If I try to just copy paste something without understanding it I don't know how to fix error messages or make tweaks so that it fits the spell I'm trying to make so I need to understand your system first and I tried reading about it for a while now and I'm just having too hard of a time, sorry.

• Magic Shield

    • -------- make sure that there are no unwanted variables --------

        • Set EOT_Param_Type = TempInteger
        • Set EOT_Param_Positive = True
        • Trigger - Run EOT_Trigger_Create_EOT (ignoring conditions)

What am I supposed to do here? I don't know what variables I'm missing or what variables I don't need or what I'm totally lost trying your system. I copy pasted your triggers from your file and the variables and everything I had to make one by one it took forever but I did it.

Well... as stated in the first comment in that trigger, the event should be made with a damage detection system.
To find out how that works, you should just try one.

But for the actual buff.
There is a part in the documentation about how to use it which might help you out.
I guess you will understand most of it when you read through that.

The more complex parts will then come up and I can tell you how they work, but for now try to figure most stuff out by the documentation.
(A big ass piece of green text in the trigger.)
