Casting of "Crushing Wave" spell in all directions

[Neruvatar]

I would want a tower to cast "Crushing Wave" at every 2 seconds at 0, 20, 40, 60, 80, 100, 120, 140.... 320, 340, 360 degrees... How would the trigger be?

 

[Rheiko]

It should be something like this

• YourTower
  • Events
    • Time - Every 2.00 seconds of game time
  • Conditions
  • Actions
    • -------- Your Tower Location --------
    • Set TempPoint = (Position of YourTower)
    • -------- Your point target ability location --------
    • Set TempPoint2 = (TempPoint offset by 300.00 towards TowerAngle degrees)
    • -------- Create a custom Crushing Wave ability based on Carrion Swarm --------
    • -------- Then order your tower to cast it --------
    • Unit - Order YourTower to Undead Dreadlord - Carrion Swarm TempPoint2
    • -------- Keep track of the angle which always changing every 2 seconds --------
    • Set TowerAngle = (TowerAngle + 20.00)
    • -------- Remove leaks --------
    • Custom script: call RemoveLocation(TempPoint)
    • Custom script: call RemoveLocation(TempPoint2)

Make sure to make a Crushing Wave based on Dreadlord's Carrion Swarm.

I thought he wanted the tower to cast the spell in each direction every two seconds, like below.

Spoiler: Example Triggers

I assumed this is for a pre-placed tower because I'm lazy at the moment and didn't want to go through making this MUI. We can do that later on if you need to, but you'll have to give us some more information about your spell and possibly your map. In the meantime, there's this.

The first trigger just sets up a few variables. Since you said it was a tower, I assumed that it wouldn't be able to move and so you can store it's position in a variable without having to clear the leak and create a dummy unit at that same position. I also stored the number of waves and the degrees between each wave; in this case, 18 and 20 respectively.

• Aqua Nova Setup
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Set Position = (Position of Tower 0000 <gen>)
    • Set NumberOfWaves = 18
    • Set Angle = (360 / TempIntLevels)
    • Unit - Create 1 DummySpecial for (Owner of Tower 0000 <gen>) at Position facing Default building facing degrees
    • Set DummySpecial = (Last created unit)
    • -------- No need to clear the location leak here because we will use it for the loop --------

The key thing to take from the periodic trigger is the loop; it will run though the actions once from 1 to 18 (18 = NumberOfWaves). For each time, it will set the angle, the target point and cast the wave. So at 1, 2, 3, ..., 18, the angles will be 20, 40, 60, ..., 360 (0). The offset amount isn't an issue unless it's beyond the cast range of the dummy spell. And a Rheiko stated above, it's best to use Carrion Swarm as Crushing Wave has an inherent lag associated with it that cannot be fixed (same goes for War Stomp, Thunder Clap and Shockwave).

• Aqua Nova Periodic
  • Events
    • Time - Every 2.00 seconds of game time
  • Conditions
  • Actions
    • For each (Integer TempInteger) from 1 to NumberOfWaves, do (Actions)
      • Loop - Actions
        • Set TempReal = (0.00 + (Real((Angle x TempInteger))))
        • Set Location = (Position offset by 256.00 towards TempReal degrees)
        • Unit - Order DummySpecial to Undead Dreadlord - Carrion Swarm Location
        • Custom script: call RemoveLocation( udg_Location )

 

[Rheiko]

Ah right, I probably misunderstood the OP.

 

[Neruvatar]

What's the difference between the triggers @Rheiko and @Dehua_Darbuya ?

 

[BloodSoul]

Rheiko's trigger casts one crushing wave every 2 seconds, but it also changes the angle with every cast, adding +20 to it. While Dehua_Darbuya's casts, at once, 18 crushing waves in a different angle at a tower location.

 

[Neruvatar]

WOw... OKay... Thanks! GOtta try them out in my project!

 

[BloodSoul]

One thing that I forgot to say is, the Angle variable that Dehua_Darbuya created is diving 360 by a variable (TempIntLevels) that has not value set before.

• Set Angle = (360 / TempIntLevels)

So, it should probably be something like this:

• Set Angle = (360 / NumberOfWaves)

And this:

• Set TempReal = (0.00 + (Real((Angle x TempInteger))))

should be:

• Set TempReal = (Real((Angle x TempInteger)))

I would want a tower to cast "Crushing Wave" at every 2 seconds at 0, 20, 40, 60, 80, 100, 120, 140.... 320, 340, 360 degrees... How would the trigger be?

To change Crushing wave cooldown or angle step go to USE ABILITY trigger.

 

[Neruvatar]

Will this be OK as well?

• Baellarum Might
• Events
• Unit - A unit starts the effect of an ability
• Conditions
• (Ability being cast) Equal to Heat Wave Roar
• Actions
• For each (Integer A) from 1 to 20, do (Actions)
• Loop - Actions
• Set baellarum1 = (Position of (Casting Unit))
• Set baellarum2 = (baellarum1 offset by 500.00 towards (18 x (Real((Integer A)))) degrees)
• Unit - Create 1 Dummy for (Owner of (Casting Unit)) at baellarum1 facing (Angle from baellarum1 to baellarum2) degrees
• Unit - Add Heat Wave Dummy to (Last Created Unit)
• Unit - Add a 1.00 second Generic expiration timer to (Last Created Unit)
• Unit - Order (Last Created Unit) to Undead Dreadlord - Carrion Swarm baellarum2
• Custom script: call RemoveLocation(udg_baellarum1)
• Custom script: call RemoveLocation(udg_baellarum2)

No. It will immediatly launch all waves. Try the template i attached above.

 

[Neruvatar]

*I'm not with my laptop now... this Saturday perhaps*

So, yours is releasing a wave at each specified angle after each passing second right?
So if I want to launch all waves in different angles at the SAME TIME, that trigger also helps? Does it leak?

If you want at the same time when use trigger you linked above,
My one (where you can choose timer between waves and angle) doesn't leak

 

[Neruvatar]

So basically both of our triggers don't leakk...... right?

 

[Fruit Forest]

in your trigger I've found one problem.
1.baelarum1 point must be outside the loop (and remove loc baelarum1 also must stay after the loop)
2. Loop triggers are very unfriendly to locations variables. You need to create array (baelarumM[x] for example and then
set baelarumM[Integer A] = blah blah
then remove location. These two actions must be inside the loop.

 

[Dehua_Darbuya]

To add to what @Fruit Forest said, you should also move your dummy unit outside the loop instead of creating a new dummy every angle. And you don't need a location array like he said because you set and destroy the location each time, one after the other. Here's the trigger by the way.

• Baellarum Might
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Heat Wave Roar
  • Actions
    • Set Baellarum1 = (Position of (Triggering unit))
    • Unit - Create 1 Dummy for (Owner of (Triggering unit)) at Baellarum1 facing Default building facing degrees
    • Set DummyUnit = (Last created unit)
    • Unit - Add Heat Wave Dummy to DummyUnit
    • Unit - Add a 1.00 second Generic expiration timer to DummyUnit
    • For each (Integer TempInteger) from 1 to 20, do (Actions)
      • Loop - Actions
        • Set Baellarum2 = (Baellarum1 offset by 256.00 towards (Real((18 x TempInteger))) degrees)
        • Unit - Order DummyUnit to Undead Dreadlord - Carrion Swarm Baellarum2
        • Custom script: call RemoveLocation(udg_Baellarum2)
    • Custom script: call RemoveLocation(udg_Baellarum1)

The problem is will the dummy unit can cast 20 times at the instant moment? Ithink the part about create 20 dummies was right.

As long as the dummy has 0 cast point/backswing and 0 movement speed (in fact, not having to turn in order to cast a spell), yes.

Good to know.
