Thunderstorm

[lavar3]

Hey Guys!
I am working on my map and i am trying to make a spell similar to Thunderstorm from world of warcraft - http://www.wowhead.com/spell=51490/thunderstorm but i cant make it at all Please i need somebody to make this spell for me in GUI version I just want the spell to be AOE, to damage enemies on the selected area and to knock them back from the center of selected area in some distance

I'll give credits +rep!

There are Knockback systems (GUI) you can use in the Spell section, the damage can be dealt easility with "Unit - damage unit" or "Unit - Damage Area" and the effect can be created with "Special Effect".

 

[lavar3]

Spartipilo, bro i am not so noobish as you think I actually didn't make the damage to be dealt in Area cuz then it gonna damage friendly units too, right? I used the "pick unit group" in "target area ability beign cast" and "if/then/else". I did the special effects too, but i can't make the knockback properly

 

[Blazing_Legion]

Use the angle between tartet point and picked unit. Point with polar offset position of picked unit offset by(xxx) towards above angle. Put this in the loop trigger and i guess u could use this with your damage group or make a separate one if u want. That should work then off course just remove leeks.

 

[lavar3]

I made the spell + knockback, but it pulls back just one enemy unit .. not all units ;o and i used the Unit Group - Pick every unit. Here is the spell - just check out that it works on one troll, but on the multiple group of trolls it pulls just one and does only damage to the others. Please, fix it for me cuz i dunno exactly how.
Also I used as base some other triggers but ofc i am gonna give them credits
Please guys, help me

 

[Spartipilo]

You can trigger AoE damage and filter units with "Matching = Enemy, and Matching = Alive" You can also add "Matching = Ground Unit", or Hero, or Flying, or Ethereal, or whatever.

There's a tutorial to do GUI Knockback in tutorial section I would love to do it, show you, and everything else... but can't do it right now

---

EDIT
You're kockbacking only 1 unit because you're setting the unit into a variable, in a different loop. The "Thunderstorm Knockback" pushes back the last unit that was added into the Knockback Unit variable in the "Pick Every Unit" loop. The best way to do this is using Hashtables.


This is an example of Hashtables, MUI, and Knockback. Adapt it to what you want, shouldn't be that hard =).


Btw, i love the lightning effect of your skill

 

[lavar3]

I still can't make it ;s Please, could you make it for me. Thats cuz i still don't understand hashtables so good and its a bit harder ...

 

[Spartipilo]

Dude... I can do it... but the Tutorial already includes a Knockback example... I would do the same, and I'm not The tutorial includes also a Map example!

 

[lavar3]

Man, it includes knockback that is single targetable, i don't need single targetable knockback, but multiple AOE knockback that knockbacks the units from targeted area. I can't make it at all, cuz i dunno how to use the triggers from the tutorial map, that u gave to me, so and I need a little help .. :|

 

[Spartipilo]

There, I edited the Knockback in the Hashtable MUI tutorial to make it AoE. Didn't used the editor... but I guess it should work.

It could be improved, but I don't have the time now. It may bug if a unit goes through unpathable terrain (like getting blocked inside trees, or water)

 

[lavar3]

Man its very confusing I cant get it All these triggers that i have to put in my spell and set them .. argh didnt make it :| ... Could you do it ... Just fix the Thunderstorm to knockback all units and upload it so i can directly import it into my map, please

 

[Spartipilo]

Sadly, no. You'll have to learn .

I'm editing the post with the trigger to help you creating and setting the variables.

Just do the trigger lines one by one... You'll get it in no time.

It gives me error message for the custom scripts and disables the trigger ...

 

[Spartipilo]

Custom scripts are case sensitive. You have to type them "exactly" as they are.

Also, the things inside // --- \\ are not part of the custom script.

What error is it giving?

 

[lavar3]

Spartipilo, i added the both triggers on another map and the good thing is that, it doesn't give me the script error anymore. But it still doesnt knockback the units .. :/ despite of the fact that I made the things just like yours.

 

[Spartipilo]

Actually, you didnt.

• Set Enemy_Group = (Units within 300.00 of Point1 matching ((((Matching unit) is A structure) Equal to False) and ((((Matching unit) is alive) Equal to True) and ((((Owner of (Matching unit)) is an enemy of (Owner of (Casting unit))) Equal to True) and ((((Matching unit) is A H

Declaring the Group into a variable with a set bj_wantDestroyGroup = true doesn't work.

Lol, you won't believer this xD You forgot to create the hashtable! You created the variable to handle the Hashtable data, but never created the hash!

I already got it working. I'm trying to "smoth" the bash.

Didn't found the way to make it "Smooth", but works. This is not the more efficient system... but "works". I'm not sure if I changed somethimg, so I'll post it all.

You still have to set the Collision Size to 0 at the beginning of the stun, and then restore it at the ending... And prevent units from going unwanted places.

 

[lavar3]

Bro, u are awesome xD It worked! Thank you so f*cking much that u wasted your time writing me all these things, I actually learned how to use hastables too ! +one big rep for u, bud. I just have one little question more - why do I even need to change their collision, if they actually dont "climb" on hills, cuz i tested the knockback infront of cliff and they didnt go up

And i think it gonna bug if i set in Map Initialization knockbackTable to be the last created hashtable cuz it gonna mess with other spells that use hastables too, right?

 

[Spartipilo]

Thanks.

About the hashtable on map init, no, you don't have to worry about that. As long as you create a Variable to handle that hashtable, since it's handled with variables.

Create a Hashtable
Set Hash1 - Last created Hashtable
Create a Hashtable
Set Hash2 - Last created Hashtable

See? You manage the first using Hash1, and Manage the second using Hash2.

If you stand in front of the unit you're bashing, it will knock against you (or any other unit/structure that's just standing there) over and over, without moving. I think that, if set the collision size to 0, the unit will go through trees and stuff, but not over cliffs. Doesn't matter that much anyway, it's just cosmetic.

Also, I think the formula should be divided (if it's equal or greater than 1) by "Remaining Time", since having a 200 x 0.04 would go through 400 distance, not 200... But if the time is lower than 0, it should be multiplied, otherwise it would go even higher.
