Spell Frozen Orb

[Flare]

My latest creation, a spell based on Diablo 2's Frozen Orb ability (it launches an orb of ice which launches shards of ice at rapid rate, dealing damage to anything that gets in its way)

I intended on submitting this for the Ice spell contest, but it didn't follow the rules (was originally created before the spell contest, even though it wasn't working properly)

Frozen Orb
Launches a large orb of frost, which fires chilling shards of ice around it, destroying everything in its path.



This spell is fully MUI, up to 100 instances (maximum number of instances possible with the way the spell is currently made is about 300 since there is 27 bolts fired per cast, and 8192 (max array size, isnt it?) divided by 27 will give roughly 300)

Spell is made in GUI, with small amount of JASS for leak removal

There are no leaks that I can see

There is a small bit of lag, but considering about 7 or 8+ units are being periodically moved at a time, it isn't bad (BEWARE: SPAMMING THIS SPELL 5+ TIMES BEFORE THE OTHER ORBS HAVE BEEN DESTROYED IS A VERY BAD IDEA)

Implementing:
 -Copy the 5 triggers within the Frozen Orb category
 -Copy ALL the custom units (Hidden Dummy, Bolt Dummy, Orb Dummy).
 -Copy the hero ability Frozen Orb
 -Change any necessary configurable properties (they have comments above them)
 -Add the Frozen Orb ability to your hero.

Screenshots (they are pretty damn large ^^):

Please leave feedback, bug reports and suggestions.

If you are going to use this spell in your map, please give me credit

Officially approved as of 3rd Jan 2008 ^^ (my second approved spell, and my final GUI spell)

HUGE UPDATE!
I've reworked the damage triggers, so that potential bug about ownership of damaging unit will NOT occur. I've also removed all instances of (Custom Value of (Picked Unit)) and replaced it with tempint.

The spell should now be safe when repeatedly cast.

 

[Hatebreeder]

Screenies please.
Other than that, your Coding is fairly well made...

 

[Flare]

Sorry for the delay with screenshots, ImageShack was taking unusually long time.

 

[cr4xzZz]

But where's the map?

 

[Flare]

Hmmm... uploading the map wouldv'e been the smart thing to do

 

[waaaks!]

ok this is usefull for GUI users
now i found 3 spells with this kind of category
2 are jass and 1 is gui

good job

 

[Flare]

good job

thanks ^^ waaaks, you got a link to those JASS version of frozen orb, i tried searching but cant find either

still waiting on a few more comments :S

 

[denmax]

I forgot about Diablo II now but I just gotta ask something,

Does Frozen Orb work this way? Creates shards of frost that is constant in its direction of fire? (look, it starts at the back part ALWAYS(?))

 

[0zaru]

Wow i never played diablo 2, and i was going to do a spell like this for the spell contest

 

[Flare]

I haven't played Diablo 2 in a LONG time (without mods that is), and I'm 99% sure that the firing pattern is random but two things:

A) I never said it was exactly like the Diablo 2 ability, I just said that it was based on it

B) I personally prefer a... regular (if that's the correct word for it) launching angle for the bolts

lol 0zaru, poke out your eyes now before you see the code, or someone is gonna call it 'help' ^^

 

[0zaru]

Nah, i have most of the code made, but now i have to add some things more to make it different from other spells ... . Anyway mine is in JASS so the judges will know that i made it by myselft =P

 

[Doom-Angel]

wow realy nice job though i didn't check but if i remember right it shoots in all directions randomlly but not totally like it shoots in a certain precent to everywhere but it's balanced to all sides in the game (i think)
anyway good job (+Rep)

 

[mc117]

For some reason your map isn't working for me, it just launched a icicle towards the point i target and thats it.

For some reason your map isn't working for me, it just launched a icicle towards the point i target and thats it.

The first trigger is disabled. Open using WE and enable then test it. (Why is it disabled anyway?). Cool spell. Complicated triggering .

BEWARE: SPAMMING THIS SPELL 5+ TIMES BEFORE THE OTHER ORBS HAVE BEEN DESTROYED IS A VERY BAD IDEA

I tried it . The floating text seems very confusing if there are a lot of units. Instead of having the floating text, why not create some icy SFX on the affected unit? (Not sure its a good idea though, and not sure whether it lags or not that way).

i thought about it too but how would he detect when the unit comes within the icicle?

 

[vypur85]

>i thought about it too but how would he detect when the unit comes within the icicle?

Not sure. But he could create floating above the affected unit, so maybe its possible to create SFX at that particular point. I've not read the triggers (too complicated, or maybe too much things to look at) so im really unsure whether the SFX can be done or not. (But i still think it is possible ).

 

[Flare]

thx for the pointing out the disabled trigger ^^ i forgot to re-enable it after getting a custom script wrong (said OrbCV instead of udg_OrbCV when destroying casters location )

as regards creating an sfx, what sfx could i use? frost nova would cause lag in the current situation (mass peasants bundled on each other ^^), freezing breath wud be a big ugly, and i dnt kno if there is any small sfx suitable for it

OK, I fixed the disabled trigger and its now uploaded.

i thought about it too but how would he detect when the unit comes within the icicle?

what exactly do you mean by that?

Complicated triggering

its not THAT complicated, its just the fact that everything bar the icicle spawn is dealt with in that trigger :S. if i moved the damage from FO movement to Orb damage or Bolt damage, it wouldve taken a significant chunk out of the FO movement trigger, but wouldve been too much trouble, since i would have to detect which bolt came within range of the unit. and, in the end, the movement trigger is just 2 very similar unit group loops ^^

 

[Doom-Angel]

what exactly do you mean by that?

i mean if you try doing that with an SFX like getting a dummy to cast something that will throw the icicle but that wouldn't work unless the target of the dummy is a unit since you cannot detect like that if they came across each other (the target and the effect)

 

[vypur85]

as regards creating an sfx, what sfx could i use?

Just a suggestion. What about the 'Unit Missile - Frost Wyrm....' SFX? Seems cool enough . Not sure it will lag or not but, if it does then you could try out with other icy missile SFX and see if its nice or not. Or else, just stick with your current one will do . (But i still feel that the floating text is kinda useless because if there are too many units then there is no point of looking at the values anymore).

 

[Flare]

hmmm, i might add frost nova SFX to units hit by the orb, and the icy SFX thats left on units who are Slowed (its a snowflake kinda thing from wat i remember)
