[Trigger] Help with a "water wall" spell

Marsunpaisti · Jul 5, 2009

So, I would like to create a "water wall" type spell, which makes the hero shoot a "wall of water" from behind him to in front of him. I have created a dummy unit with a shockwave based skill where its projeticle has been changed to waterfall but I have no idea how to calculate the positions for the dummies so that they are in a line behind the hero.

Get the facing of your hero which will be a real value the represent angle then add 180 degree and when creating the dummy unit, create it at the caster position offset by r and the new angle which will be the hero facing angle + 180 then let that dummy unit cast the spell towards the hero facing angle.

I don't know why it doesn't work but it seems logical to me that what I have said is right. Well try making the variable of the point not of array type; I know it wouldn't make difference but just try.

ok here you are but its vauge and I used the same spell for the caster and the dummy also the caster is the dummy which will result in chain cast, you take the idea and change the spell as you see fit. here is the triggers.

Untitled Trigger 001
- Events
  - Unit - A unit Starts the effect of an ability
- Conditions
- Actions
  - Set castpoint = (Target point of ability being cast)
  - Set dummypoint = ((Position of (Triggering unit)) offset by 256.00 towards ((Angle from (Position of (Triggering unit)) to castpoint) + 180.00) degrees)
  - Unit - Create 1 Tauren Chieftain for Player 1 (Red) at dummypoint facing Default building facing degrees
  - Hero - Learn skill for (Last created unit): Orc Tauren Chieftain - Shockwave
  - Unit - Order (Last created unit) to Orc Tauren Chieftain - Shockwave castpoint
  - Trigger - Turn off (This trigger)
  - -------- remove Turn off, I just added it so the trigger stops creating anymore unit --------

Also note that there are two versions of shock wave when matching the conditions.

Yes but that trigger just creates one unit behind the hero, when i need many units in a straight line behind the hero.

What do you mean by: 'i need many units in a straight line behind the hero' ?

He needs a WALL. You know Diablo 2, fire wall? So, he needs that one unit and then many units in front of it. So it makes a WALL.

OK that explains much, if that what he really needs. I thought he want the wall come from the caster bach toward forward and damaging any enemy it encounter, like Beast Master - stampede ability.

Yes, kind of like that but only one big wave of the shockwaves coming and all of them come at the same time.

Have you tried changing the field of the Shockwave ability for the dummy unit, make a bigger area of effect so that it matches the size of the missile.

Just_Spectating · Jul 6, 2009

It wouldn't look like a wall Starquizer.

He just wants the Positions of the Dummy units.

Smiddle has the right idea.

Marsunpaisti · Jul 6, 2009

In my opinion, it would look really ugly.

By the way, would it be possible to do it so. That first i would create an unit behind the hero, then make it face the hero and then create units with polar offset in a line based on the unit?

Just_Spectating · Jul 6, 2009

thats the gist of it.

You set the offset by about like 250? behind the unit (so like, Facing degrees of triggering unit + 180) or something, (facing triggering unit degrees), then after that action, (Facing of Last Created unit + 90) with offsets of like 250, 500, 750, Then you go the other way (Facing of Last Created unit -90) and add your integers by 750 so that it can reset to the middle and go left, (1000, 1250, 1500)

Yes, that's it.

It will be easier to make it if you want an odd number of dummies.

I made the spell for you; maybe not exactly the way you want to, but it might be really close:

Ok solved, but now I got another problem. How can I make the waterfall effect show up when the dummy casts. Now when the dummy casts the skill only a ripple will show on the ground (when shockwave casts it creates a small ripple).

I think its unsolvable because Shockwave always creates a ripple in the ground even if you set the effects to null.

I don't think he said anything about removing the ripple (which you can use Carrion Swarm for btw), he just said that no effect showed up.

Which one were you trying to use? Crushing Wave missile?

Marsunpaisti · Jul 7, 2009

I tried to use the doodad waterfall

Marsunpaisti · Jul 7, 2009

By the way, the spell you made, made the water effects all move into same point, when i would like them to go forward from behind the hero like a wall.
