Circle of Blades

[Renendaru]

I have no idea how to code this one... But was wondering if someone else did.

I need a circle of blades to fly to a target hitting any units in the way. Which spin in a circle along the way.

You will need some kind of blade/sword model that you can use for the spinning.
Then I guess you can make a trigger which orders the model to spin by facing different directions, and move it forward at the same time. (Better yet would be if the model has some spinning animation to begin with.)

If i were u, i would use Shadow Hunter's normal attack as for the spinning blades, and add a normal fire to each and one of them, to get them spinning im not rly sure how to >.<

Shadow Hunter's blades automatically spin, but in my opinion they would be too big, imagine 3 or 4 of them in a circle, it would be massive, unless you scaled them, then they dont look as good, I reccomend using Glaive (Maybe too big) or Spell Binder's missile.

You mean Spell Breaker, right?

That would be the perfect model for those blades:thup:

Well, it was pretty easy to code it actually.

Sliding Wispwheel.
Made in vJass.
Requires: NewGen and HAIL (HAIL can be found in the demo map.)

How to implement:
Copy the SlidingWispwheel trigger to your map with the dummy, change the raw codes to yours.
If you don't have HAIL in your map simply copy that too. You don't have to change anything at all inside of it.

Code:

scope SlidingWispwheel initializer Lightning
//! runtextmacro HAIL_CreateProperty ("Data", "integer", "private")
globals
private constant integer dummyID = 'u000'  //Dummy unit raw code.
private constant integer raw     = 'A000' //Ability raw code.
private constant integer damage  = 25    //The damage dealt to each unit.
private constant integer aoe  = 200   //The area of effect of the damage.
private constant real speed = 0.05 //How often the sliding runs.
private constant integer distance = 700 //How far the "projectile" goes.
private constant integer offset = 100 //Distance from the center to the dummy units.
private constant integer dummyamount = 16//How many dummy units that will circle

group Az
unit WispwheelCaster  = null
endglobals
private struct TestStruct
real RotateAngle
real angle
unit array dummy [dummyamount]
integer delay
integer FirstTime
real tx
real ty
timer Timer
unit caster
integer distance
endstruct

Not sure how to do it MUI in GUI. But I think one way is to move an invisible dummy in a straight line. And then let another visible dummy to circle around the invisible dummy. There could be some maths formula for this though so that the invisible dummy is not needed. But I don't know what is it. My maths is a bit rusty .

Edit:
=.="

 

[Kazuga]

You don't have to use an invisible dummy, use the point of which you would have moved the invisible dummy. Making it MUI in GUI would be a real pain though...

 

[vypur85]

> Making it MUI in GUI would be a real pain though...

Yeah... Tried it, and failed . Thought of playing with some sin graph and all but also failed . Using JASS should be much much simpler. I can't learn it though.

 

[Kazuga]

>I can't learn it though.
Why? It's a lot easier than many thinks. Though I have to admit that some things are so complicated that even I don't fully know what they do even if I know how to use them.

 

[vypur85]

I've learnt a bit actually. Played around with Kattana's handle var. But I can't test map =.=. I'm using Kaspersky and my WC3 is copied from my friend's. Tried a lot of things and failed, finally gave up. And so, that's the whole story... I'll just stick with GUI......

Spoiler

Yes, yes... Fine... Laugh all you can...

 

[Renendaru]

I'll test your spell, Kazuga, when I can. Right now I'm on my laptop w/o Wc3.

 

[Tastyfish]

you need something like this?:

I followed that and it wasn't a big deal to turn it MUI or something like that .
But the orbiting stuff dont stay fixed and might clump together, atleast in my trigger.

 

[Renendaru]

Kazuga's works fine....

Thanks Kazuga.
