How to get return values from ActionScript calls
Overview
Just a short and simple tutorial on how to get a return value when calling an ActionScript function from UnrealScript.
Simple variables
First, our calling function:
function GetRetValueOfASFunction() { local string retVal; retVal = CallASFunction(); `log("MyASFunction() Return Value: " @ retVal); }
function string CallASFunction() { return ActionScriptString("MyASFunction"); }
function MyASFunction():String { var retVal:String = "This text is being returned from a Flash function called by UnrealScript."; return retVal; }
Arrays and Objects
For retrieving the return value of something more complex, like an array, something like this would work:
function GetRetValueOfASFunction() { local array<GFxObject> retVal; retVal = CallASFunction(); `log("MyASFunction() Array Element 0 Return Value: " @ retVal[0].GetString("Name") @ " | " @ retVal[0].GetString("Type")); `log("MyASFunction() Array Element 1 Return Value: " @ retVal[1].GetString("Name") @ " | " @ retVal[1].GetString("Type")); } function array<GFxObject> CallASFunction() { return RootMC.ActionScriptArray("MyASFunction"); }
function MyASFunction():Array { var retVal:Array = [{Name: "Testing", Type: "String"}, {Name: "Testing 2", Type: "Float"}]; return retVal; }
