[SOLVED] Strange behavior of vector in recursion

[r.nikonov]

Hello

 

Short example:

class T {
    string a;
    T(string value) { a = value; }
};

class My {
    int _flag = 0;
    int _test[0];
    T _test2 = new T("old");

    void test() {
        log.message("before:\t" + string(_test.size()) + "\t" + _test2.a + "\n");
        int local[] = (1);
        T local2 = new T("temp");
        log.message("after:\t" + string(_test.size()) + "\t" + _test2.a + "\n");

        local.append(10);
        _test = local;

        local2 = new T("new");
        _test2 = local2;

        if (_flag == 0) {
            _flag = 1;
            test();
        }
    }
}

Expected:

before: 0 old
after:  0 old
before: 2 new
after:  2 new

Real result:

before: 0 old
after:  0 old
before: 2 new
after:  1 new

I found almost answer in same tagged thread: https://developer.unigine.com/forum/topic/3042-solved-vectors-maps-and-recursion/

This: "That's because local variables in UnigineScript aren't actually local. They're global with local function scope."

Hi Roman,

 

Yes, this is expected result, sorry (all variables are "static" by default in UnigineScript).
