How do you extract a Sprite back out of a ByteArray?
I should probably post this into some AS forums (and will do so later), but I had to get this out there quickly and it’s bugging the hell out of me:
In short, how do you extract a Sprite from a ByteArray? (or any kind of display object for that matter).
I can write the object just fine, and read it back into a variable, but I’ll be blown if I can then convert that back into what it was originally.
Here are my attempts so far:
var test:Sprite = new Sprite();
//addChild(test); // to test, works fine
var b:ByteArray = new ByteArray();
trace(b.length); // 0 bytes
trace(b.length); // 754 bytes, so our Sprite is definitely in there
// Reset the pointer
b.position = 0;
trace(b.position); // 0 as I’d expect
//newTest = b.readObject() as Sprite; // Ends up being null
//newTest = Sprite(b.readObject()); // Type Coercion failed error
//addChild(newTest); // and kaboom, constant “Parameter child must be non-null.” errors 🙁
var take2:Object = b.readObject();
trace(take2); // ok take2 contains an object, but how can I get the Sprite out of it?
trace(b.position); // 754, so it has definitely read it all
Ummm someone, please help? 🙂
