ZScript Discussion

Code: Select all

    Array<Line> Next()
    {
        Array<Line> loop;
        
        
        
        return loop;
    }

This function makes my GZDoom silently suicide on init. (closes without error, remains in the process list)
Replacing Line with anything else still causes it.

It should print an error. You cannot return local stack variables.

[ZZYZX]

Pls add either Actor.GetArg0Str() or more universal typecast from int to Name (since arg0str is Name(-args[0]), but that's not possible due to how VM works).

[Marrub]

With the new [wiki]ScriptCall[/wiki] function, would it be possible to call a function on the activator, rather than a static function?
Or, at least, some way to identify the activator in a way that a static function could find them.

[Graf Zahl]

Calling a function on the activator is not possible because the activator has no type and you cannot extend Actor.
Passing the activator should be doable later but will be tricly to implement safely.

[Marrub]

Doesn't the ZScript VM have RTTI? If so, couldn't you just look up the type from that?

[Graf Zahl]

... which may bring us into even worse undefined situations if the function that gets called can differ, based on class, and ever require different parameters if you get two classes with the same method name but no relation to each other. Far too dangerous for my taste. A static function is always a well-defined entry point.

I wonder if it's possible to hack Visual Studio or VS Code somehow to support ZScript? Having Intellisense on ZScript files would be cool to have.

EDIT: VS Code is promising. Just by installing the C++ extension and then opening your ZScript files as C++ (I had to change the ZScript file to have a .cpp extension) works quite well. You can do let <something> and autocompletion works (I see all my custom fields!), and most methods inside your class are recognized and can be peeked at, just like in Visual Studio.

What doesn't work yet is if you do MyClass.MyMethod. Need to figure this out.

I think with a little tweaking, a ZScript extension can be made to fully recognize it.

[Nash]

let p = new("MyClass");

MyClass cannot be an Actor, otherwise the game crashes. Bug or by design?

[ZZYZX]

Actor.Spawn

[Nash]

I don't want it to be an Actor. It's just a data class.

[ZZYZX]

In which case you shouldn't try to make an Actor-derived class using new().

[Nash]

Man, I wish there was a way to only compile ZScript without actually running the game. I'm guessing the sum of the total accumulated time every time my ZScript fails to make the game start has reached hours by now, haha...

[Xaser]

Hmm, which brave soul is going to write ZSLint?

What's wrong with batch files/bash scripts and binding F10 to quit without dialogue?
