[Prototype Spell] Water Blast

Daffa · Oct 13, 2013

Well, I have made an old spell back a few months ago, but haven't really gotten around it to do some tweaking and making it better.

I also attached the map, feel free to leave a feedback for me to improve it before I upload it to Spell Section.

Planned Modifications :
Use X/Y Reals instead of Locations
~~Find a better way for enumeration check to stop trigger execution if no unit in group~~
Add New Features and stuff

Updates :
15 October 2013 : Major Trigger Tweaking & Rebalance Damage - Update Test Map
14 October 2013 : Minor Trigger Tweaking - Update Test Map

Unit - Move (Picked unit) instantly to WB_KnockLoc2
-> Unit - Move WB_TempUnit instantly to WB_KnockLoc2

the others are good, well done

Daffa · Oct 14, 2013

Nice catch Rheiko!
Updated!

pOke · Oct 14, 2013

Hm, if I remember correctly the creategroup native doesnt work in vanilla, you might want to double check because I'm sure it works in jngp but if you upload as gui the thought is the spell works in regular WE.

chobibo · Oct 14, 2013

I think you could use a single tree detector unit for this.

Actions
- Custom script: set udg_WB_DestKiller = CreateUnit(Player(15), 'hpea', 0, 0, 0)
- Unit - Hide WB_DestKiller

Events
- Map Init
Actions
- Custom script: set udg_WB_DestKiller = CreateUnit(Player(15), 'hpea', 0, 0, 0)
- Unit - Hide WB_DestKiller

Daffa · Oct 14, 2013

What do you mean? I only use one Tree Detector unit.

Maker · Oct 14, 2013

-Locust the harvester
-udg_WB_Knocked is automatically created at map init
-Too many loc variables, use the same in both triggers
-Do number of units check only after removing a unit from the group
-Follow through time

chobibo · Oct 14, 2013

Ah, fuck, sorry. I never saw the on map init event lol.

Thanks, will do them once I can, I'm not at laptop at the moment.

TriggerHappy · Oct 14, 2013

The triggers look okay to me.

:thumbs_up:

Daffa · Oct 14, 2013

Thanks!

pOke · Oct 15, 2013

In the Loop trigger, only pick every destructible if the WB_DestroyTrees is true, don't check for each destructible.

Could reduce the lag by not creating a special effect on the trees, but might take away from the spell...idk

P.S. I was wrong about CreateGroup() not working in regular WE.

I shall consider that

pOke said:

That's why it's configurable, I might add the same to unit as well, it's a user preference.

It's not a VJASS native, so we can use it in normal WE

PurgeandFire · Oct 15, 2013

It should deal a little less damage so I can actually see the knockback applied. They all die.

Or give the hero only the lvl 1 spell in the test map (but allow him to skill-it-up).

No such thing exists (vJASS native)

You can use all the natives that you see in (v)JASS scripts, vJASS only extends the language with syntax elements, but it doesn't (cannot) implement new natives, or anything similar.

Okay, will tone it down

Thanks for correcting me!

You can implement natives in JASS like the native UnitAlive takes unit u returns boolean by typing it in your code in vJASS.
But I don't know if you can do this in GUI too ^^'

I wouldn't really call them 'custom', or at for me 'custom' means something that cannot be found in the game's files

But good point.

Malhorne · Oct 16, 2013

Yes they aren't really custom since they are in the ai.j ^^
But anyway it is good that we can use those because some of it are awesome

I've been using UnitAlive over all those tricks ever since I learned of it

Malhorne · Oct 16, 2013

Yes I'm doing it too :3

chobibo · Oct 16, 2013

Can you use that without JNGP?

Malhorne · Oct 16, 2013

Nope

TriggerHappy · Oct 16, 2013

chobibo said:

You can't declare it in the map, but AFAIK you can manually via game files.

JassHelper moves it to the appropriate place.

Also, you can't just declare natives. They have to exist somewhere else (UnitAlive is in common.ai).

chobibo · Oct 16, 2013

Where do you declare it? on the war3map.j?

TriggerHappy · Oct 16, 2013

JassHelper Manual said:
Warcraft III supports declaration of natives in the map script, but it requires the natives to be declared just after the script's globals section.

http://www.wc3c.net/vexorian/jasshelpermanual.html#ndf

chobibo · Oct 16, 2013

Thanks. So it's possible to use that native if you export and re-import he map script.

Daffa · Oct 16, 2013

Okay guys, lets stop the unrelated posts :cgrin:

Back to main topic, is it acceptable at this rate? If so, I will upload this to the spell section (I only forget 1 thing : adding Invul to dummy unit).
