  • Code optimisation
  • Added a configurable to have the original death animation
  • Fixed the configurables
  • Create method takes a player, and a unit - sourceUnit and whichPlayer

Ouch O_O

I should see this spell if it requires so many libraries.

Edit: OK, tested.

1. My computer only handles 2-3 simultaneous before significant framerate drop. Using fewer blades couldn't hurt in case multiple users have selected that hero.

2. I know it's customizable, but the blade model could be a lot better, such Glaive Missile.

3. Blood and sound effects are good. I don't have much experience with sounds so I have no further imput on that.

4. Why are you nulling struct members?

Nothing wrong with so many requirements, they are all commonly used systems.

Actually, I could remove Damage from the list, and replace it with the Blizzard native, but I like Damage (lol) :D
I could also let go of GTrigger and use the native register.
But nah.

1. My computer only handles 2-3 simultaneous before significant framerate drop. Using fewer blades couldn't hurt in case multiple users have selected that hero.

Hm. I actually intended to have a '1 INSTANCE PER UNIT' option like my Whilrpool spell, I'll get around to that. This spell is made of 60 units per instance, all moving around... I wander if how I am applying the actions to the chainUnits good or bad, I know nothing of Linked Lists ;o


2. I know it's customizable, but the blade model could be a lot better, such Glaive Missile.

This is meant to recreate Pudge War's Blade Barrier, it was only made of Spell Breaker missiles. So yeah, you try it and tell me how it looks.

Heck:
Compare.jpg

Here it is, left = Glaive, right = Trail missiels.

3. Blood and sound effects are good. I don't have much experience with sounds so I have no further imput on that.

All compliments to Tossrock on the blade sounds.

4. Why are you nulling struct members?
Good practice to, even if they are globals and will be used again, there is no harm in doing so. Infact, you'll see a lot of people null members in structs.

I understand good practice, but with 60 missiles 300 needless function calls when the spell wraps up is excessive. (Setting to null takes the same speed as calling an empty function).

Spell is good, the whirl effect looks really sweet and I like to see what people are currently making with vJass capabilities.

You have to lock up millions of handles before there is any problem, so nulling arrays which already have a limit of 8000 is more likely a good practice to avoid. Similar to how nulling triggers and players is something better off ignored. I think most oldschool JASS coders are just in the habit of nulling every little thing, but since I never had to develop that habit I can see past the overkill.

Really? o.o, wow.

This spell is nothing compared to SANDMAN. :)

Ok. I'll just leave every global unnulled o_O

I really like it :infl_thumbs_up: The effect in the end that makes the blades fade away is well made.
I forgot to mention that :p

I really like the fade effect ! There's only one thing I ask MRFAN to change about it: please make them dispell right from the circle instead of moving back to the caseter. I think the effect would be more realistic as right now the fast-pace of the spell has a comparatively long mull before releasing the blades...

Since when is nulling the same speed as calling an empty function? =P Nulling is nearly twice as fast.

------------------------------------

Anyway, some comments on the code.

Any particular reason for these 3 variables?
JASS:
            local real ticks = 0
            local real tempDur = SPELL_DUR
            local real radius = BLADE_AOE + 20

They don't seem to be used.

For this set this.owner = GetOwningPlayer( this.caster ), you can use GetTriggerPlayer() instead since benchmarks show it is faster. =)

JASS:
            call TriggerRegisterUnitInRange( this.t, this.caster, BLADE_AOE + ( 45 - COLLISION_SIZE ), BOOLEXPR_TRUE )

You can use "null" without worry now as of patch 1.24. GroupUtils isn't really needed if you just recycle them.

JASS:
            call TriggerAddCondition( this.t, function thistype.damageCond )

Shouldn't that be Condition(function thistype.damageCond)?

You can also use this directly as so:
JASS:
 static method GroupDestroy takes nothing returns nothing
            call BladeUnitData[GetEnumUnit()].cleanup()
        endmethod

Rather than the local declaration and then the call x.cleanup().

JASS:
static method periodic takes nothing returns boolean
            local thistype this = KT_GetData()
            local integer  r
            local sound    s = null
            set tempData = this

In that method you don't use r nor s, so you can simply remove them. =)

In static method rotateBlade takes nothing returns nothing, you need to null the bladeUnit variable.

For this line:
JASS:
        method AddBlade takes nothing returns nothing
            local unit blade = CreateUnit( this.owner, DUMMY_ID ,GetUnitX(.caster),GetUnitY(.caster), 0 )

You should save the X/Y of the caster into global variables/members of the struct temporarily so that you don't need to calculate it 59 extra times.

JASS:
  IsUnitType( this.originData.caster, UNIT_TYPE_DEAD ) then

You might want to use native UnitAlive takes unit id returns boolean instead. (Declare the native wherever you want in the scope and then use it [it is a native from common.ai])

---------

Other than that, awesome job on the spell. Really nice eyecandy, and cool idea. =D

Have you people never played Pudge Wars Advanced lol? It's the same from that. But anyways, I'll need to do the 'on list' things and what Purge mentioned.

Shouldn't that be Condition(function thistype.damageCond) ?
Doesn't JassHelper do that for you?

Done to null, but I like GropuUtils as it's just two lines. NewGroup() and ReleaseGroup(), and people already use such systems :)

Ok. I'm going to try do stuff on the do list now.

Yeah, but that doesn't take away from the fact of it being an awesome spell. =P

Oh, I didn't know that. I wasn't sure, you can just leave it as it is then. =)

Well, I guess it is up to you. But just remember that group recycling (more like "reusing" rather than recycling, it is never dumped at all) is effectively done without "using" any lines (sort of, or at least not any extra lines). =D If you are interested in it, you can read this real quick (it is pretty short [if you haven't already read it]): How to use Groups without leaking
