[vJASS] Atomic Bomb v3.1.0.1

The documentation explains everything you need to know.

JASS:
/*************************************
*
*   AtomicBomb
*   v3.1.0.1
*   By Magtheridon96
*
*   - Creates a bombing plane behind the caster
*     that will drop an atomic bomb dealing damage
*     to enemy units in an area of effect. Deals
*     bonus damage to closer units.
*
*   Requires:
*   ---------
*
*       - CTL by Nestharus
*           - hiveworkshop.com/forums/jass-resources-412/snippet-constant-timer-loop-32-a-201381/
*       - SpellEffectEvent by Bribe
*           - hiveworkshop.com/forums/jass-resources-412/snippet-spelleffectevent-187193/
*       - Particle by Nestharus
*           - hiveworkshop.com/forums/submissions-414/snippet-needs-work-particle-206279/
*
*       Optional:
*       ---------
*
*           - TimerUtils by Vexorian (This also caters to my version of TimerUtils in the Hive Jass section Graveyard)
*               - wc3c.net/showthread.php?t=101322
*
*   Importing:
*   ----------
*
*       - Copy this code to a new trigger.
*       - Make sure you have all the requirements implemented too.
*       - Go the object editor and copy/paste the objects to your map (1 ability, 2 dummy units).
*       - There is also an object called Particle that you need which is part of the Particle library.
*       - Import the special effect and dummy.mdl to your map.
*       - Configure the data in the globals to your liking.
*       - Done!

Finally, after more than a year, I've updated this spell and it works perfectly :)
It used to be in GUI, but I finally had the time to rewrite and fix it.

Oh, and the testmap is a must-see ;)
I made it so that it's like a demonstration :D
Just type 'start', then sit back and watch the show 8)

6 April 2012 Bribe: This is a very good example of well-written, readable code, and since it works flawlessly from what I can tell from my tests, I will go for approving this.
Why are you creating a local rect and removing it right after? There is the SetRect native to avoid this very thing, so you could technically use a global rect here.

I thought you had a trick that did this all in one line?:

JASS:
        private static method isTree takes destructable d returns boolean
            local boolean result = false
            call PauseUnit(treeDetector, false)
            set result = IssueTargetOrder(treeDetector, "harvest", d)
            call PauseUnit(treeDetector, true)
            return result
        endmethod
 
Yeah, I know, but it wasn't working, and I was debugging this for 3 days in a row, so I decided to upload it as is.

I'll optimize it right now :p

edit
I found a bunch of other errors too. I just fixed them.
I'm going to review it one more time before I update it.

By the way, did you like the test-map? :D
A pretty cool way of presenting a spell, right? ^_^

edit
Updated.
Optimized and made the Demo slightly better.

But it would be a minor improvement nonetheless. I've also found that the the ability hotkey for usage in the testmap is displayed as Q but the learn hotkey is set as R. Also:

WANTED: EXPLOSION
DEAD OR ALIVE


No explosions in the testmap :( You set the constant integer PARTICLE_ID as 'h000' instead of as 'n000'. I was thinking why the spell looked different from what was shown on the image and why no explosion was evident.
 
Oh Magtheridon, you silly willy man, why are you using bj_lastCreatedGroup?

--- To save handles dude...

But have you ever considered the worst-case scenario?

--- What?

What if a unit dies due to damage from this spell, and there's a function registered to a death event using group enumeration with bj_lastCreatedGroup. It would totally bug the entire thing!

--- Oh my... I feel so stupid... I'm going to update this spell and all the others.
Thank you Magtheridon you awesome man <3

No problem bro <3
 
1) Why are you destroying timers and using TU instead of just creating 1 timer for all and just loop it?

I am doing that, but the thing is, the effects are not synced with the spell loop, so I'm creating a timer to expire after 1 second (configurable) so I can remove the "Particle", which is like an effect with Z (A dummy unit, pretty much)

The reason I've added the Timer destroying is because I'm TimerUtils an optional requirement :D
If you don't have it, the spell destroys timers, else, it recycles them.
 
why make a snippet for it if the system is already existent and you can just import it? the thing here is that we don't like redoing things that are already done...

as for the suggestion, I'd like to see that too...

This >>>...coz IMO, the used library requirement is overkill for a single spell, Particle library for example requires at least 4 additional add-ons...

EDIT:
I may also add a suggestion to use TimerTools which will replace CTL and TimerUtils...take note that this is just my own opinion and maybe ignored :)...
