Tornado Suck-in trigger

[Spartipilo]

Hi!

I'm working on a TD where there's a Wind Elemental that has a random chance to create a tornado that sucks units in 350 AoE into it. To make it more realistic: near units are more attracted than far units.

The thing is, I don't want to interrupt unit orders so I have to do it with X/Y coords and i'm not that good on math.

It's not like Dota's Dark Seer Vaccum which sends them all to the center, but rather increase the "sucking power" nearer the units are from the base of the tornado.

I would really appreciate any help!

Offtopic

I also have an Earth elemental, but I don't know what AoE effect give to it. Any ideas?

 

[Chaosy]

cant you save issed order into a variable and order unit to do that after the vortex?

 

[Spartipilo]

Sure I can... the only order is "Attack"... but, as far as I know, working with real coords is faster than doing with locations..

Anyway, can you help me doing it either way?

BDW: Sorry If i said something wrong. English is not my native language.

something like this i belive it should look like for my sulution

• Untitled Trigger 001
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Animate Dead
  • Actions
    • Set point = (Position of (Target unit of ability being cast))
    • Unit Group - Pick every unit in (Units within vortex_area of point) and do (Actions)
      • Loop - Actions
        • Set Order = (Current order of (Picked unit))

That's the easy part xD How to "suck" units in?

When I said I wasn't good at math I meant to say "I have no Idea how to do this".

 

[Chaosy]

i can make the spell for you tomarrow since im tired now if thats ok.

 

[Spartipilo]

Yeah, sure. Maybe i'll try to do something about it later, but I doubt i'll get something

350 AOE is very insignificant small circle, and it would not affect the Sucking Power of a unit, I mean there is a small difference of Sucking Power if you include a small area to to cover compared to 1000 AOE, where you can see 500 distance unit are more attracted to 900 distance unit

If you are to use a 350-AOE, the difference is too small

 

[Spartipilo]

But the roads where creeps goes by have about 350-400 width and they go right through the center, so, for 3 seconds, it will suck units and get them all together for other towers deal the AoE damage.

I want it to suck like an espiral... Like a big inverse toilet I think it will be noticeable... Anyway, if it's not enough I can just change the radius later, but the system would be the same... right?

 

[defskull]

Do you want a realistic suction power ?
You will be sucked in a spiral shape, not directly moves towards the tornado

Which one do you want ?
Realistic suction or directly suction ?

 

[Spartipilo]

Realistic. In spiral shape towards to the right (The direction tornados spin in Wc3)... I don't care if it's hard to do, I'm willing to put all my effort into it.

- Spiral shape towards right
- Increase the suction power the nearer the unit is to the tornado base
- If possible, better using X/Y instead of Loc.

I'm just thinking that maybe it could have around 500 AoE, but the units will move 350 distance towards the tornado in spiral shape, so, units in a distance lower or equal to 350 will end in the center of the tornado, while the other units will reach (500-350) distance towards the tornado, so, they would end up at 150 distance from the tornado... (Just an idea).

There is no pathing detection, you need to add that.

The suction power will be 0 at max distance and full when distance is 0. You can ofcurse modify it by editing
Set r2 = (1.00 - (r1 / MAX_PULL_DIST)) . That will determine the pull power.

OMG! It's so awesome! How can I make the unit move towards the tornado in the same cliff level? If I set the condition in the movement part it won't even move, so... ¿?

 

[Maker]

How can I make the unit move towards the tornado in the same cliff level?

• (Terrain cliff level at point) Equal to (Terrain cliff level at point2)

The last call RemoveLocation is in a wrong place and is causing a leak.

Ok... i got this

The creeps just stop moving if they're in the same cliff level, I'd like them to move towards the tornado in the same level without going over cliffs and other unpathable terrains, like going in the border of the pathable way.

You can do pathing checks with using some system like Nestharus' pathing library, using the item method or testing walkability at p2.
