Code:
obj
    Battle
        density = TRUE
        icon = 'Techs_Ki_Blasts.dmi'
        var
            delay = 1
            length = 15
            damage_divider = 100
            damage = 100
            dominant = 0
            splash_radius = 0
            splash_damage = 0
            daze = 0
            mob
                owner
        Blast
            New(location, mob/shooter)
                if(!ismob(shooter)) return
                src.damage = round(shooter.kipower * src.damage_divider)
                src.dir = shooter.dir
                if(!src.loc) src.loc = shooter.loc
                src.owner = shooter
                spawn(1300) del(src)        

            Energy_Blast
                icon_state = "Energy Blast"
                delay = 1
                splash_radius = 0
                daze = 0
                length  = 8
                damage_divider = 300

mob
    proc
        EnergyBlast()
            for(var/obj/Battle/Blast/Energy_Blast/c)
                c.damage_divider=1000


Problem description:

I am trying to edit damage divider for energy blast once usr click on an icon in tech tree the proc EnergyBlast() activate. But it wont edit it and can please someone can help me out with it.

Use the object's Click() proc (At least that's what is sounds like you're trying to accomplish?..)

obj/Test_OBJ
    Click(mob/M)
        M.EnergyBlast()

mob/proc
    EnergyBlast()
        ..()

No i want to change damage divider once proc is activated. But somehow damage_divider is still 300

Where is the /obj/Battle/Blast/Energy_Blast? I assume you only want to change the Energy_Blast's damage_divider for the player who "researched" it in the tech tree. Do you store each player's techniques in a list somewhere?

If you put some debug output (such as world<<"Triggered damage_divider change!") in that for() loop, is it getting triggered?

Yea thats what I wanted to to. Once player learns tehnique he have it in stats in src.techniques

Sry for dubble post. I also tried to do
for(var/obj/Technique/Ki_Attacks/Energy_Blast/T in src.techniques)

but still aint working + undefined var since only obj is defined

Oh, okay. I think I understand now.

/obj/Battle/Blast/Energy_Blast is a projectile that you create when the player uses their "Energy Blast" technique. You can research an improved version in the tech tree to increase the damage [multiplier] of each Energy_Blast projectile you fire.

However, you can't change the initial value of a type's variable itself--you have to change the value of an existing instance of that type. If you want the damage_divider to be dependent on the mob firing it, you'll need a variable on the mob that controls that. Then you can reference it in your projectile's New() just like you do with shooter.kipower.

Ok so how am i suppose to change length of this projectile since value cannot be changed ?

You have to add some sort of logic to your New() process to alter the values. You can't change the variable's initial (aka default) value at runtime.

I'm trying to think of a general-purpose approach for handling something like this, but I'm not sure how to explain it. Basically, what I'm thinking is you could give each player a list of "modifiers" (which would be datums). Each modifier would reference a type path, a variable name, and the new value for that variable. Then in the New() process of any type you want to be modifiable, you would run a process to check if the player has any modifiers for the current type, and apply them if so.

Maybe I'll throw together a library for it..

And what if im just using verbs for it :
var/damage = src.owner.kipower*2 + rand(550,850) - A:defense + src.owner.kiboost // kiboost changed from damage_divider

src.owner is shooter
and i do same for length. But the problem is if im going to have like 10 attacks that means 20 verbs just for attacks.

That will work, but like you noted, it can get out of hand quickly. (I assume you mean "vars" instead of "verbs"?)

Stay away from the colon.
