Shockwave Knockback

[Gost]

The spell I want to make: Hero targets point, shock wave travels that direction for 500/600/700/800) units when the shock wave comes in contact with units it pushs them to the sides.

Now how I imagine I would do this is to upon casting create a dummy unit with the shockwave model and knock'back' it towards the target point. But I am unsure how to leaklessly & lagfreely knockback the units it comes in contact with.

I would think that I could have a trigger that every .4 seconds picks every unit matching unit-type equal to that of the dummy unit, then pick every unit around that and knock it back. But the problem with that is a unit could get knocked back twice.

So I was wondering if I could get some suggestions on how to make this work.

you can just clean up your leaks with

set bj_wantDestroyGroup = true

I'm not sure what would solve, my problem with my proposed solution is that a unit would get picked, be knockbacked, but get picked agian and get knockbacked again (twice) by the same shockwave.

EDIT: Unless you were just giving me advice on how to remove leaks from gui because I asked for a leakless solution. I already knew how to do that but thanks anyways

well it wouldnt be bad if the shockwave knocked back units more than once, then it gives you a more of a tactical use of the ability, so that more advanced players would try to hit a unit head on so it gets knocked back the distance of the shockwave.


else, you can give the unit a buff when the shockwave unit is near, then if the unit has the buff, knock back as necessary, then remove the buff.

True, *working on it*

Or just add them on a group named knockedback
dont knock them if they are in knockedback
and clear that group in the end

If you are doing it that way, be sure to use Breath of Frost as a base spell, since it's a cone/line ability that gives a buff without triggers.

Breath of Frost gives no buff, its a bug, it should, but it doesnt.

I've been busy and just got around to it, and realized that as redscores said BOF gives no buff, I'm going to try BOFire quick I'll edit this post with my results.

 

[Just_Spectating]

breath of fire has buffs.

 

[StaberFire]

I wouldn't suggest Breath of Fire, since it is a different area effect than shockwave.

I would use the dummy, as you had said, and give it an aura. Then check units that have the aura's buff in the knockback trigger, as Just_Spectationg suggested.

i would create a dummy with shockwave model and move him with offset in a line and pick every unit within 200 of its position checking if it is an enemy and if it isnt in knockbacked units group... then ill knockback them and add them to knockbacked unit group...


I think thats the best way


Greetings

PS: i think need_02 sayd that xD

EDIT: Oh! btw i dont think the aura thingy will work the same because auras have a little delay to affect units... am i correct? and might not have the same result as "pick every unit within position..."

 

[StaberFire]

That's true, I forgot about the part where he doesn't want them to get knocked back twice. XD

Anyways, darkrider's solution seems to fit best with this problem. Well done, sir. Oo

You should remove/clean all of your variable as soon as you think/know that you don't need them anymore,and you should find a way to optimize all those HUGE triggers into smaller ones (I have no intention in looking at 20+ triggers today ...)
