[Trigger] Detect Units with Locust & Stampede question

[Peacehagen]

Hello again xD

I have 2 questions.


1. I was working on a Boss mechanic where the Boss spawns fireballs (dummy units) randomly in the room which then moves towards the boss at random speed, dealing damage to players coming near. When the fireballs reach the Boss they disappear.

The problem I encountered is that I would like the fireballs to have locust, but then the triggers cant detect them when they come within 200 of the boss. When replacing locust with invulnerable, it works, but then the fireballs has health bars if players have it on.

Is there an easy way to detect units with locust or should i just stick with invulnerable instead?


2. I wanted to use the stampede spell as a Boss mechanic aswell but wanted it to be tornados (which worked) but the problem is they still splash blood when hit just like regular stampede, even though i replaced the blood model with a lightning effect. Anyone knows how this works or if it cant be changed?

Thanks in advance!

1) How about not using Dummy units at all?

Relativistic Missiles [vJASS][LUA][GUI]

Relativistic Missiles v2.8 by Chopinski Introduction First of all, Credits and thanks to BPower, Dirac, and Vexorian for their missile systems at which I based this system upon, and to AGD for the help with effect orientation methods. This is a Missile system that I put together...

Otherwise, you need to add the Locust units to a Unit Group manually and then use a Periodic trigger to compare their Distance from the Boss. You can destroy them once they come within range and then remove them from the Unit Group.

2) I believe some effects are bugged and will always use the "base" effect. This is found on the original ability or buff. Unfortunately, this means that ALL of your Stampede abilities will share the same art effects. Maybe it'd be best just to remove the art entirely. You can also trigger a custom Stampede spell and avoid this headache (the above system would actually work great for this).

Ok, that looks like a really neat system, will see if I can get it to work However I got this error when i tried to copy it over to my map. I copied all triggers except the "This Map Only".

Do you know whats wrong?

 

[Nichilus]

that is because you have imported lua script into map that is running jass. The system you imported probably has vJass version as well, so import that one into your map.
The other option is change the map's setting to use lua instead of jass. Do note if you change that, then any jass/vjass script you have in your map will stop working instead.

I imagine you don't want to use Lua, so download the Jass version and make sure you have JassHelper enabled (there's a dropdown menu in the Trigger Editor).

Alternatively:

You can store locust units in variables and have a trigger check every 1 second or whatever if the unit is close to your boss. I have some similar boss fights.
I made a short code snippet for checking unit distance (well, technically, the distance between any 2 points):

function UDistance takes real AX, real AY, real BX, real BY returns real
    local real dx = BX - AX
    local real dy = BY - AY
    return SquareRoot(dx * dx + dy * dy)
endfunction

If it's not clear:
AX is the X coordinate of the first point, and so on.

Alternatively, you can use the goblin mine abilities and check in a trigger if the ability has been triggered / or the unit has died. I also have a few scripted abilities that do that successfully. I don't remember if it works with locust or not.

I tried the vJass version and got 2 errors this time xD
Jasshelper is active, I have other vJass systems that work fine

@emperor_d3st ty for your reply but i am really bad with coding, all i can do myself is gui xD even as simple as your suggestion seem i dont know how to edit/use it to fit my need.

Try copying the system folder that I have in this map, I don't think you should get any errors. I believe I removed the "extras" since Chopinski sort of threw all of his systems into one folder.

 

[emperor_d3st]

I think you might have this:
World Editor has a bug: Sometimes it copies libraries to the core of the map (or whatever it is called officially, I forgot, you know, the very top of the trigger editor).

So your library will exist twice. Just remove the one in the core of the map.

It worked to copy the folder from the arcane missiles

Seems to work very well for my Boss ability so thats great just one thing if any of you know, is it possible to delay the missiles movements?

Preferably I would like the missiles to spawn, then wait 2 seconds before they start moving towards their point so players has time to react and see where there are free space? I looked at the Pause spell from the missile system map but it seems to paus all missiles in a specific area? so if a hero uses the missile system for one of their abilities it would potentially paus its missiles aswell or do I misunderstand how it works?

If its too complicated to do I will just reduce the number of missiles that is created to make it easier to dodge.

There's most likely a proper way of doing this, but I'm not a complete expert at the system yet. What I would try to do is set the missile Speed to 0 and then after 2 seconds increase it to the proper amount. I imagine you could do this by taking advantage of the On Periodic trigger and MissileData.

So give it a default speed of 0.00 and tell it run the following trigger every interval (I assume the missiles use a 0.03 or 0.0325 second interval):

• // Define your Missile settings...
• Set Variable MissileSpeed = 0.00
• Set Variable Missile_onPeriod = BossMissilePeriodic

This trigger will run every interval:

• BossMissilePeriodic
  • Events
  • Conditions
  • Actions
    • Set Variable MissileData = (MissileData + 1)
    • If MissileData Equal to 65 then Set Variable MissileSpeed = 900.00

I can't promise this will work because MissileData and MissileSpeed may not get updated properly.

@chopinski
Sorry to bother you but perhaps you'd be so kind as to share a solution to this delayed missile effect?

 

[Peacehagen]

@Uncle unfortunately it did not work but I think you are on to something.

I found in the pause triggers that you could pick missiles of types (defined by number of choice). However, when using this method only like half of the missiles started moving.

• R13 Fire onPeriod
  • Events
  • Conditions
  • Actions
    • Set VariableSet Counter[Missile] = (Counter[Missile] + 1)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • Counter[Missile] Equal to 65
      • Then - Actions
        • Set VariableSet MissileGroupType = 1
        • Set VariableSet MissileGroupCounted = 20
        • Trigger - Run MissilesOfTypeCounted <gen> (ignoring conditions)
        • For each (Integer MissileAt) from 0 to (MissileGroupSize - 1), do (Actions)
          • Loop - Actions
            • Trigger - Run PickedMissile <gen> (ignoring conditions)
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
              • Then - Actions
                • Set VariableSet MissileSpeed = (Random real number between 250.00 and 500.00)
              • Else - Actions
      • Else - Actions

Maybe you would need knowledge of the system to know why only some of them moved.

 

[Uncle]

Hmm, not sure. An easier solution may be to just create the Dummy missiles, then after 2 seconds Remove them and fire a Missile System missile from their position.

 

[Peacehagen]

True, that is an easier way to do it. Thanks alot for the help!
