Unity Serializer v0.965 – RELEASE CANDIDATE 1

I am releasing the first release candidate of Unity Serializer. Thank you so much for all the help in testing.

[Fix] Removed more warnings concerning ScriptableObject instantiation
[Fix] Problems saving colliders in certain circumstances
[Fix] DoNotSerialize can target events
[New] IControlSerialization interface to allow components to specify that they should not be saved
[Fix] Joints were not storing motor and spring properties
[Fix] Rigidbodies weren’t always saving correctly in certain circumstances
[New] Getting started guide included in install
[New] iTween and PlayMaker packages included in AddOns folder
[Fix] Improved object activation
[Fix] Errors created by having duplicate prefabs (AddPrefabPath + normal)
[Fix] Problem with properties not always having a GetMethod (explicit interfaces?)
[Fix] Can now store terrain (so that it can be moved)

Unity Serializer PlayMaker extension now has custom actions

I’ve added custom actions to the PlayMaker serializer to enable saving and resuming from checkpoints and also saving and loading games. There is an example scene in the download that shows using these actions to make a simple save game menu 100% in PlayMaker.

The download is available here.

New Unity Serializer Getting Started Guide

I’ve added a longer Getting Started guide for Unity Serializer that you can access here.  I have also split out the API reference which is available on this page.

There will be an FAQ coming soon.

Unity Serializer v0.951

Version 0.951 contains a series of fixes from inbound bug reports. No new features are expected

[Fix] Rigidbody no longer reports warning when kinematic
[Fix] Multiple similar components allowed on the same game object (broken in 0.941)
[Fix] Activation status of sub components could be overwritten
[Fix] Creation of scriptable objects caused a warning
[Fix] Wrapped UnityEditor using directive for builds

Unity, Vuforia & ZXing – Barcode scanning in AR games

I’ve been struggling with finding a good barcode scanner/QR code reader that works with Unity and doesn’t kill the framerate.  Given that I also have an AR application I thought that I would try to incorporate Vuforia with ZXing to get the best of both worlds and the good news is that it works pretty well and is very fast.  I’m attaching a download here of the package that contains a Unity friendly version of the C# port of ZXing together with my mulithreading manager Loom class.  Then here is an example of a script that will scan barcodes and/or QR codes and fire an event and send a message to a target object when something is decoded.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System;
using System.Linq;
using com.google.zxing.qrcode;
using com.google.zxing.multi;
using com.google.zxing.common;
using com.google.zxing;
using com.google.zxing.client.result;

[AddComponentMenu("System/VuforiaScanner")]
public class VuforiaScanner : MonoBehaviour
{
	public QCARBehaviour vuforia;
	public bool barcode;
	public GameObject target;

	public static event Action<ParsedResult, string> Scanned = delegate {};
	public static event Action<string> ScannedQRCode = delegate {};
	public static event Action<string> ScannedBarCode = delegate {};

	bool decoding;
	bool initGray;
	MultiFormatReader mfReader = new MultiFormatReader();
	QRCodeReader qrReader = new QRCodeReader();

	void Update()
	{
		if(vuforia == null)
			return;
		if(vuforia.enabled && !initGray)
		{
                     //Wait 1/4 seconds for the device to initialize (otherwise it seems to crash sometimes)
		     initGray = true;
		     Loom.QueueOnMainThread(()=>{
	                      initGray = CameraDevice.Instance.SetFrameFormat(Image.PIXEL_FORMAT.GRAYSCALE, true);
		     }, 0.25f);
		}
		if (vuforia.enabled && CameraDevice.Instance != null && !decoding)
		{
			var image = CameraDevice.Instance.GetCameraImage(Image.PIXEL_FORMAT.GRAYSCALE);
			if (image != null)
			{
				decoding = true;

				Loom.RunAsync(() =>
				{
					try
					{
						var bitmap = new BinaryBitmap(new HybridBinarizer(new RGBLuminanceSource(image.Pixels, image.BufferWidth, image.BufferHeight, true)));
						Result data;
						if (barcode)
						{
							var reader = new MultiFormatReader();
							data = reader.decode(bitmap);
						}
						else
						{
							var reader = new QRCodeReader();
							data = reader.decode(bitmap);
						}
						if (data != null)
						{
							Loom.QueueOnMainThread(() => {
								if (data.BarcodeFormat == BarcodeFormat.QR_CODE)
								{
									ScannedQRCode(data.Text);
									if(target != null)
									{
										target.SendMessage("ScannedQRCode", data.Text, SendMessageOptions.DontRequireReceiver);
									}
								}
								if (data.BarcodeFormat != BarcodeFormat.QR_CODE)
								{
									ScannedBarCode(data.Text);
									if(target != null)
									{
										target.SendMessage("ScannedBarCode", data.Text, SendMessageOptions.DontRequireReceiver);
									}

								}
								var parsedResult = ResultParser.parseResult(data);
								if(target != null)
								{
									target.SendMessage("Scanned", parsedResult, SendMessageOptions.DontRequireReceiver);
								}
								Scanned(parsedResult, data.Text);
								decoding = false;
							});
						}
					}
					catch (Exception e)
					{
						decoding = false;
					}
				});

			}

		}
	}
