Looking for auto-splitting behavior or trigger. As performance friendly as possible.

There is no trigger to make units split but it is not very hard to create one.

The easiest way would be to add all the units to a unit group and do something like this:

void autosplit(unitgroup g) {

    fixed countdown;
    fixed delay;

    countdown = 10;
    delay = 0.5;

    while(countdown > 0) {
        diverge(g);
        wait(delay);
        countdown -= delay;
    }

}

void diverge(unitgroup g) {

    unit u;
    unitgroup others;
    point p;
    point avoid;
    point destination;
    int i;
    
    for(i = 1; i < sizeofunitgroup(g); i += 1) {
        u = UnitGroupUnit(g, i);
        others = g;
        removeunitfromunitgroup(others, u);
        p = positionofunit(u);
        avoid = positionofunit(closestunittoposition(others, p));
        if(distancebetweenpoints(p, avoid) < 2) {
            destination = pointoffsetbypoint(p,-2,avoid);
            issueunitorder(u,move,destination);
        }
    }

}

That code would run for 10 seconds and make all the units run away from eachother for ten seconds to a maximum distance of 2. So they would spread out without scattering.

There are better ways you could do it but that's probably the easiest

Thank you, how do I convert this code to trigger?

Nevermind, made my own and it works just as i need.

That's great! I didn't know the exact function names or syntax off the top of my head but I'm glad you were able to follow it and implement your own.

If you can, upload a clip to youtube. I love watching that kind of stuff where units make a descission individually and yet it results in group organization.

EDIT: you said it works, but i realized a small mistake i made. instead of "others = g" i meant to put others = copyofunitgroup(g). theres some function which makes a copy of a group whereas i think "=" just passes a reference to the same group

No i made totally mine from scratch. Can't upload, too long but i can give you the trigger:

There is not too much to look at, units move chaoticly but it does the job of making space they take bigger.

you have to use the "markup type" button and put your code inside these tags
