[Trigger] Need help: limitations of GUI & JASS damage displayer

[G-force]

hello guys,

i've been a long time visitor of hiveworkshop.com although i never actively participated in these forums myself. I'm a big fan of orpg maps and i have been toying around with the editor for a long time, but recently i have begun a more serious attempt to make an rpg map of myself.

however i've ran into a big problem: i am a total novice at JASS, and i ran into a trigger that i want to make, that cannot be done with just GUI. Since JASS seems to be a reaaaaally complex codelanguage (for a novice like me anyway) and since i already mastered GUI, i am not really eager to start learning JASS.

Is there any way i can enhance the GUI options of the trigger editor by means of an unofficial patch or mod or something of the sorts? that would be the perfect solution to me.



also, could an experienced JASS codewriter translate this into JASS(or something like this)? its not possible to make this in GUI alone (in my version of the editor anyway):

events:
a unit takes damage

conditions:

Actions:
Create floating text that reads (string((damage taken))) above (unit taking damage) with Z offset 100.00 using fontsize 10.00, color (100%(red),0%,0%) and 0.00% transparancy

change hight of (last created floating text) to 250 over 5 seconds

Change the lifespan of (last created floating text) to 5 seconds

Change the fading age of (last created floating text) to 3 seconds



any help would be greatly apprieciated

Since there is no "a unit takes damage" event in warcraft, it is achieved a bit differently.
Anyhow, this has been discussed SOOOOOO many times. Search for "damage detection" systems (spells, systems, threads, whatever).

 

[Maker]

Create another trigger that has an action

• Trigger - Add to damageDetectionTrigger <gen> the event (Unit - (yourUnit) Takes damage)

Run the trigger and then the damage detection works.

ah I catch your drift maker, I can see how that would work. But my map will hold hundreds of units, which will all need to be entered into a variable, and have their own event. wouldnt a variable array with a size of several hundred and hundreds of events cause a ton of lag?

 

[GhostWolf]

You do not need to hold them in any array (and no it won't lag at all). The bad point at this is that it leaks events - when a unit dies, the event stays.
That's why I told you to look for an on-damage system, damage-detection system, or whatever they are called.
They solve it by destroying the trigger and recreating it from time to time (the less times the better, since destroying triggers can cause bugs).

Ghostwolf, could you explain how to do this without a variable unit array? i thought Maker ment something like this (see below), but i could be wrong... i dont see how to do this without a really long variable, since my map will hold a ton of enemy units.


Trigger one: unit creation trigger

event: not important
condition: not important
Action: create unit.................
set variable (unit array #....) to last created unit


Trigger two: floating text creator

events: (unit array #1) takes damage
(unit array #2) takes damage
(unit array #3) takes damage
etc...
conditions:
etc...

I do not have warcraft and I hardly remember GUI's syntax, but it's something around this:

• AddEnter
  • Events
    • Unit - A unit enters the map
  • Conditions
    • // might want to leave unimportant units out
  • Actions
    • Add event ((Triggering Unit) takes damage) to OnDamage

• AddBegin
  • Events
    • Game - On Map Initialization
  • Conditions
  • Actions
    • Custom script: set bj_wantDestroyGroup = true
    • Pick every unit in (every unit you want) and do Actions
      • Add event ((Picked Unit) takes damage) to OnDamage

• OnDamage
  • Events
  • Conditions
  • Actions
    • // whatever actions you want

But like I said, this leaks an event every time a unit that was checked dies. You can still use it as these leaks are small, but if you're expecting huge numbers of units to die (like an ORPG for example), you'd better go with better systems which are mostly coded in Jass (in case you do not know Jass, this doesn't mean you can't use them in GUI with 1-2 custom scripts).

I'd suggest you use a prebuilt system which is well coded and has some features for ease of use, such as Intuitive Damage Detection System. However, you'll inevitably be using Jass if you do.

I have only one really stupid sollution

Modify critical strike to make 100% of original damage at 100% chance

@ ghostwolf: when you create an event: Triggering unit takes damage, then i'm pretty sure wc3 won't recognise any unit, so that would'nt work without a variable would it?

@ Purple Root: i can't make heads or tails out of that intuitive damage detection system

 

[GhostWolf]

@ ghostwolf: when you create an event: Triggering unit takes damage, then i'm pretty sure wc3 won't recognise any unit, so that would'nt work without a variable would it?

Just try it and see.
And remember, GhostWolf is always^* right.

* aside from the times he isn't right

Did you read the documentation?
