AS3 problem with unrealScript

[Matt Doyle]

ActionScriptVoid() must be called from a class that extends GFxMoviePlayer. This class must have a SWF associated with it via MovieInfo. That is the SWF it will look for the function in.

If you want a return value, use one of the other function calls:

ActionScriptInt()
ActionScriptString()
ActionScriptArray()
ActionScriptObject()

etc...

So, you would do something like:

UnrealScript

function GetRetValueOfASFunction()
{
    local string retVal;	
    retVal = CallASFunction("someString", 38);
	
    `log("retVal: " @ retVal);
}

function string CallASFunction(string param1, int param2)
{
    // AS2 Version
    return GetVariableObject("_root").ActionScriptString("MyASFunction");

    // AS3 version
    return GetVariableObject("root").ActionScriptString("MyASFunction");
}

ActionScript

function MyASFunction(param1:String, param2:int):String
{
    var someString:String = "This is a test.";

    return someString;
}

Of course GFxMoviePlayer only has one main GFxValue right?

I didn't see those methods in the docs earlier but it certainly makes sense to have a full set, looks great.

I'd still like to know how you avoid an invoke, even with complex objects you need an invoke.

[Matt Doyle]

I'm not really sure what you're asking about GFxValue. As for avoiding the use of invoke, I rarely use it. You'll have to provide an example of where you think you have to use it.

[Matt Doyle]

Here's another working group of functions to get a return value from an ActionScript Function:

function GetRetValueOfASFunction()
{
    local array<GFxObject> retVal;	
    retVal = CallASFunction();
	
    `log("Array Element 0 Return Value: " @ retVal[0].GetString("Name") @ " | " @ retVal[0].GetString("Type"));
    `log("Array Element 1 Return Value: " @ retVal[1].GetString("Name") @ " | " @ retVal[1].GetString("Type"));
}

function array<GFxObject> CallASFunction()
{
    return RootMC.ActionScriptArray("MyASFunction");
}

ActionScript

function MyASFunction():Array
{
    var retVal:Array = []
    retVal = [{Name: "Testing", Type: "String"},
	      {Name: "Testing 2", Type: " Float"}];
    return retVal;
}

Sorry, I meant that the GFxMoviePlayer class only has one movie.

As for avoiding invoke, surely the scaleform code behind the unrealscript wrapper has to call an invoke at some point deeper down in the code

[Matt Doyle]

Ah yes - there is only one movie, but that movie can load sub movies. I couldn't tell you what's going on in the guts of Scaleform or Unreal though. That's beyond my knowledge.
