Re: Question about bgt handles
Are handles supported for strings in BGT? It's kinda weird about handles for things like vectors.
Not sure here, I just used it to clarify things, didn't test it though and creating copies of strings doesn't take too long usually, don't use it anywhere as far as I remember.
BGT doesn't let @ work on ints, floats, etc, which I believe is how it works in Java, too? But if you declare a function or method that takes "int &out" instead of just "int", that's effectively the same as sending a reference rather than a copy. ... But you don't do anything different when modifying the variable, because that would make sense -_-
Thats not all that needs to be said here. AngelScript knows three different ways of handling function parameters:
&in: only used for input references. Modifying the variable given with that parameter will either raise a compilation error or simply do nothing (don't know right now). I guess using that one isn't very useful, at least I never did that (it probably doesn't matter if you pass the handle or the variable here, since we're talking about primitive data types like int and float).
&out: only used to return a value to the outer world, the variable passed into the function won't be initialized and you can't read from it.
&inout (or simply &) does both and thus is a full call by reference call, you can read and also write to this variable.
You're probably wondering why it's "@a = b", and not "@a = @b", and I have no idea.
Its again AngelScript (BGT) that takes your hand here. @a = @b works as well, but AngelScript knows that @a can only be set to another handle and thus creates the handle of b automatically to assign it to @a.
Best Regards.
