Mui

[Nugamentum]

"Spells must be fully multiinstanceable, and done so competently (IE no "indexing systems" which just populate a massive array and count upwards until they hit a maximum, then restarting from the first possible value regardless of whether the position is taken)."

Is there a way to do MUI spells without indexing in GUI? Or do I need Jass to do that?

I heard that hashtables in Jass don't require that indexing. As for the GUI, know that it is such a restricted language, that it requires higher "pain" to get results considered as "piece of cake" for Jass. So, no, GUI requires Indexing to be converted into MUI enchanced.

You can make instant spells, they are (almost) always mui. But ofc only instant spells is quite boring.

The popular indexing systems for GUI refresh either after each cast or as soon as there's a moment in which no unit casts the spell (happens quite often).

All in all, this rule seems to be no new addition at all since usual indexing systems for GUI are allowed.
