[Trigger] What is MUI?

[Hemske]

Well, i know what MUI is. But how can you know if a trigger is MUI? What in the trigger is it that makes a spell MUI? Can someone explain this to me or link me to a tut or something (couldnt find one myself). Beacuse it would be really annoying to post every spell of mine in a thread here just so ppl could tell me if its MUI.

It usually uses an increasing Integer per cast, e.g. MUI = MUI + 1 and uses a custom IntegerA type variable, e.g. For each (MUI_Int) from 1 to (MUI), (do Actions).

Is that it?

You can test it yourself. Try to use two units and cast your spell at the same time and see if it bugs.

There are plenty of tutorials. Here are some tutorials, note, they are all different methods.

Also there's one with indexing, but I couldn't find it.

MUI stands for Multi-Instancible, this is how you make your spell can be cast at any time with any player, also try this; it might help you Click Here

MUI means Multi Units Instanceable. It means that a spell can work for many units at the same time. All Blizzrd spells are mui and it's a problem only for coded spells.

There is another MPI - thats Multi Players Instanceable - the spell works once per player - it's useful in Aos and arena maps.

For MUI spells you must:
a )avoid waits (not trouble if you do the next thing)
b )use arrays with many values and reset them when they reach the top
c )use locals (big time trouble, need jass)

To test MUI have 2 units cast the spell at the same time.

What about if i have a passive spell, that has some percentage chance to trigger, that will be hard to test by using them at the same time, right? well i can show, and you can take a look and say if its MUI, i think i have got a pretty good idea of how it works, but just for sure .

• Rune of inscribed Lighting
  • Events
    • Unit - A unit Is attacked
  • Conditions
  • Actions
    • Set InscribedLightning = (Random integer number between 1 and 100)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • InscribedLightning Less than or equal to 8
        • (Level of Rune of inscribed Lighting for (Attacked unit)) Equal to 1
      • Then - Actions
        • Unit - Create 1 Inscribed Lightning Dummy for (Owner of (Attacked unit)) at (Position of (Attacked unit)) facing Default building facing degrees
        • Unit - Order (Last created unit) to Neutral Naga Sea Witch - Forked Lightning (Attacking unit)
      • Else - Actions
        • Do nothing

Does this work at the same time? The most of the spells i am doing atm is like this one, so would be good if i know how to make them work

 

[Reaper2008]

It is MUI cause it has no Waits.

 

[Hemske]

Hmm, i see, And if i do for example target spells thingys, i should just think of avoid waits and use arrays and itll be all good? hopefully

 

[Reaper2008]

Yup.
