Is there any way to have an optional argument?

public void func(float some[3], float more[3], int args[4], char[] some-optional-arg) {
//stuff
}

yes

PHP Code:

public DoSomething(bool:something = false)
{
    if (something) //do stuff
}

DoSomething(true); // something will be true
DoSomething(); // something will be false

I knew you could do it with a bool, but how about with a string.

You can't have default values on public function parameters.

You know this is a great time to ask why overloads aren't a thing

That is a surprisingly complicated question.

Pawn doesn't have types, it has tags - which are intentionally weaker than normal typing (SourcePawn is slowly changing this and promoting tags to real types).

Rather than overloading, upstream Pawn has a feature called tagsets, which allows you to specify a list of potential tags for a function argument. You can then switch on the tag type to implement overloading inside the function (rather than dispatching to one of multiple functions). SourcePawn removed tagsets because they're really silly and require lots of extra syntax to work.

However, Publics can never support overloading for the same reason C doesn't: the mangled name doesn't include typing information (and related to why they do not support default arguments).

Information that I never knew I needed to know, for some reason i'm not surprised that there's some complex reason behind overloads not being a thing
Thanks for clarifying on that

Through StrEqual(some-opt-arg, <needed string>, <case sensitivity>) or StrContains(some-opt-arg, <string you're looking for>, <case sensitivity>) != -1 if that's the one else == -1 if that's what you're avoiding.

This is exactly the way I ended up doing it.
