It should work if you add static or public before const.

Strange, but this actually works, except in the case of charArray. Why can't you just use the const modifier? Why would I hide a constant using static or make it visible to other plugins using public?

const only works with scalars, very old quirk.On Mar 26, 2024 10:34 AM, Andrey Barkovskiy ***@***.***> wrote: It's strange, but it really works. Again, not the case with charArray.

Yea, I see...

static const char test[] = "Candy";

public void OnPluginStart() {
    MakeSandy(test);
    PrintToServer("[DEBUG] test = '%s'", test);
}

void MakeSandy(const char[] str) {
    str[0] = 'S';
}
