Hi,

not sure if i'm completly off here, but I am pretty sure it's doable.

I wanted to do it the other way around (make certain skills AOE). In the example I used Manifest Virtue.

As we know, gs has some nice and easily editable base skill classes for every skill. I noticed the ::StateAttack() though and wondered if it could be responsible for targeting... and I think it is. I quit this a few months ago though, and never got to any solution. Below is what I have commented and (thought) to have figured out correctly. Specially, I can't figure out what the hell ::SetRatio() does (a method of GNET:layerwrapper).

Did anybody ever look into this?

I'll move this to developments for you all to possibly develop something from it. If you don't like it there please let me know and I can always re-relocate it

GS skill stuff has always been very interesting but sadly nobody has ever managed to get anywhere with it. (though i did once manage to make players soulforce for psy skills be read from some other unknown part of their data, however sadly this crashed the map after a few goes as this data could have been anything)

I believe all skill and stat properties are stored inside "ext" files that get compiled into the GS but sadly we cant edit these bits with the current technology (IDA is pretty top atm). Each skill does however have code to do with it, as swoosh pointed out, but as far as i can tell this only allows us to change things such as mana cost and cooldown(?) etc.

call GNET_GetSkillVictim9 looks very very hopeful, if there is a pattern/differences between skills that are AoE or self cast or friendly cast then perhaps we are in business.

It is possible of course. I can do that or edit any other skills as you want but it's not free.
