Adventures

This week, two important things happened on my professional life:

The Universim got released on Steam! After a final lap without monthly releases, the team hit the gas and worked non stop for 3-4 months to get the game on the best possible shape.

The release was a success, and several days after release, reviews stay in good direction!

Coincidentally, almost exactly two years after joining the Crytivo dev team, I decided it was time for me to move on. August 30th was my last day on @TheUniversim team.

Working on The Universim has been one of the greatest work experiences on more than a decade of game dev.

I feel greateful, and looking forward to the upcoming challenges and next #gamedev adventures.

Web Requests From Unity Editor

Unity3D currently offers two options for creating web requests. Both WWW (an old class soon to be deprecated), as well as the new more flexible and elaborated (although still with many issues): UnityWebRequest.

Both of this Unity API classes rely on coroutines for executing the calls, which are expected to be done asynchronously. This is the standard and more recommended way creating web calls in Unity, but introduce a serious limitation: it does not allow to use web requests from the Editor, as coroutines are not available on it.

Here I will describe a very simple way to overcome this aparent limitation, using the EditorApplication.update, a delegate exposed by the Unity API.

Now, for a very simple example let's create an editor menu, that will write to the console the result of a web request done to a Google web service.

public class WebRequestInEditor { // Lets poke Maps for the distance between two cities. static string url = "https://goo.gl/bxjBI7"; static UnityWebRequest www; static void Request() { www = UnityWebRequest.Get(url); www.Send(); } static void EditorUpdate() { if (!www.isDone) return; if (www.isError) Debug.Log(www.error); else Debug.Log(www.downloadHandler.text); EditorApplication.update -= EditorUpdate; } [MenuItem ("Tools/Poke Google Web Service")] static void UpdateFromSpreadsheet() { Request(); EditorApplication.update += EditorUpdate; } }

Special Note: If you happen to have classes already using coroutines, and thus your code uses IEnumerator methods, you can save some refactoring by moving the iterator manually (described in a previous blog post) but doing it on the EditorApplication.update callback instead of a blocking while sentence.

Hope it helps! ...Until the next one!

Got your back: CloudBackend

Another short post announcing a new tool for the suite of cloud related Unity3D assets: CloudBackend!

CloudBackend offers a simple, flexible and effective backend solution, while avoiding the need for special hosting requirements, and the uncertainties introduced by third party services.

CloudBackend connects the Unity3D project with a web service -hosted on your Google Drive account-, enabling you to store player signups, logins, game stats, game statistics, etc.

Included demo

As usual, you can find it on the Unity Asset Store. Here is the Unity forum thread.

Cloudify the Unity Console

A small post to announce a new addition to the Cloud set of tools: CloudConsole!

Get the Unity development console output right on your browser, with the added option to save a log session to your Google Drive, as a Doc.

As usual, you can find it on the Unity Asset Store.

Introducing CloudPrefs

There is a new extension in the Unity Asset Store: CloudPrefs help developers handle Unity PlayerPrefs in the cloud.

Allows to have the standard PlayerPrefs while also saving some or all keys to the Cloud, using Google Spreadsheets as key-value storage.

// Standard PlayerPrefs, saving locally. PlayerPrefs.SetInt("Key", 7); // CloudPrefs: PlayerPrefs.SetInt("Key", 7, true);

Not going to describe too much here to avoid repeting myself too much, but I invite you to visit the store page, and the Unity forum thread for the asset.

This will be the first of a series of Unity extensions using the Google Sheets for Unity principle, but elaborated and enhanced into specific use cases.

Synchronous Web Request using Unity3D API

The standard way of making web requests in Unity, is using the WWW class, which is expected to be used asynchronously. This is described in the Unity docs, and is the standard and more recommended way creating web calls.

However, there are cases when we need to make synchronous requests, and get a value that will grant (or not) further interaction. A simple login system, could be a good example.

For those cases, there is no obvious way of returning a value from a method using the WWW class: its meant to be used in coroutines, IEnumerator functions that will be asynchronous and not return the value as desired.

However if instead of using StartCoroutine(), we move through the enumerator ourselves, we will be able to have a synchronous request, that will return a value as a standard function.

Below, there is a simple snipet that shows a way to do it.

public class SynchronousWebCalls : MonoBehaviour { // Lets poke Maps for the distance between two cities. string url = "https://goo.gl/bxjBI7"; void Start() { IEnumerator e = Request(); while (e.MoveNext()) if (e.Current != null) Debug.Log(e.Current as string); } IEnumerator Request() { WWW www = new WWW(url); while (!www.isDone) yield return null; if (string.IsNullOrEmpty(www.error)) yield return www.text else yield return www.error; } }

Special Note 1: Of course, this, creating a synchronous request, will hold the execution of the app or game until any result is returned from the web. It's for very specific cases and curious minds, but the way described by Unity remains the better and safer path to work with the WWW class.

Special Note 2: In the current Unity 5.4 Beta, the UnityWebRequest class, that is supossed to supersede the WWW based API, has been promoted from "Experimental". However, multiple issues have been found still (I have found mysellf a few), so until the new class be more reliable, I don't recommend to use it for production code.

Until the next one!

Upgrade

So, the upcoming Unity 5.3 will include some features that affect Google Sheets For Unity.

Specifically, a new API for http requests, and an integrated JSON serializer: this is good news for us!

The new http api will help us have more flexibility when connecting to the Google Spreadsheets, resulting on improved and safer connections, making the asset more appropriate for released products, finally becoming a serious option for beyond development time. The awesome new json serializer, free us from external dependencies (GSFU uses LitJson), which means less maintenance, a seamless integration, and very cool Unity oriented features. On late december, I will be releasing an upgraded version of GSFU, which makes use of this new features, along with a new and more complex example: a complete CRUD implementation (for those not in the jargon, crud refers to the basic functions of a persistent storage: create, read, update and delete).

In the meantime, don't be alarmed: GSFU will still work fine with Unity 5.3, even before the mentioned upgrade.

So fingers crossed day job doesn't gets too messy so the new version gets released soon.

As always, you can get updates through the facebook page this blog, and you can follow me on twitter.

I'll keep you posted!

Back On

After many months of blog inactibity, Im here again. I became father for second time, and time for blogging, twitting, and so far, was not really abundant. However I do have some comments to keep you updated about whats going on at the CyberianSoftware trenches:

A new GSFU  package is now on the Unity Asset Store. Unity 5 users, required a one time API updater operation when importing the extension. Now Google Sheets for Unity version 1.5 is up, and works out of the box with Unity5!

Some clarification for a question that has been asked: WebGL/HTML5 builds of GSFU have the same limitations than WebPlayer builds. Different approach, but a similar security approach, prevents access from web builds to Google Spreadsheets. More details can be read in the Unity docs here. 

Also, some guys have brought to my attention a small issue but can be a headache if not discovered on time: when you copy links from the GSFU pdf manual, for some reason the links are not correctly copied. Have that in mind when installing or setting up the extension. I will use another PDF writer for the the manual on the next update.

Once again, thanks to the Unity Asset Store team for a super fast submission aproval!

Before saying bye: I will have very cool news very soon! Stay tunned for announcements ;)

Piracy

I'll post just for the sake of letting others know that there is people who don't buy the "piracy" tale. Meaning, piracy is not a problem that needs a solution. For start, there is still pending to see the data which proves or suggest that publishers of content of any kind (music, movies, games, books, etc) are losing money due to unauthorized copies. [1] What is known is: publishers used to be the only way of getting to people with our content. This meant for them tons of money, but also an outstanding power. Now they are losing that power, and are trying to convince the world that they are losing money, to justify mechanisms pointing to restore them the power. Go figure, tha data shows they are making money like never in history. [2][3] And then, of course there are lots of people convinced this is true. People who, under the effect of years of a huge propaganda machine, think "unauthorized copy" == "lost sale". The ramifications of this lie are huge, and we end up having to fight sopa/pipa/acta/etc. Because this laws are the result of years of brain washing about "piracy" and "security", vs "rights". Truth is, as indies we have nothing in common with the people who push this lie. Actually, there are many indies who express a different stance, starting quietly to demystify the whole thing. [4][5][6] Time will show what always does: in the verge of a new technology, people adapt, and markets do the same. Some industries come down altogether because of this thing called "technology advance". Nobody ever cared for the guys who used to sell ice door to door, with the invention of the refrigerator. They simply adapted to new times, never asked for laws to prevent people to access ice by themselves. Publishers, in time, will perish. We? We shall adapt, find new ways of making people get our content, and still make a living of it. We shall simply be creative.

PS: This is pretty much the same comment I wrote at the GarageGames forums years go, in June 2012, in a thread regarding pros and cons of copy protection in games. I think my comment from then still holds for representing my perspective on the matter.

Madness

Google Sheets for Unity, an extension asset for Unity3D that I have developed and published on the Unity Asset Store, has been since a few days, part of one of the most important sales that the store offers: the "Madness Sale".

The whole thing of developing the extension having third party, annonymous developers in mind (as opposed to users, or players), and publishing on the UAS has been a very interesting experience, that may be worth describing, so: material for a future post.

GSFU has been on the store since about 6 months now, and this is its first time on sale. The current Madness Sale lasts for 12 days (is on the 4th day at the time of this post), and offers me the oportunity to experiment with ideas to generate more traffic, and thus improve the exposure of the extension, and see how this affect sales.

Is challeging, as Im not particulary fond for spam or practices tending to consider people on the internet, a faceless crowd whose only purpose is to buy things.

So I have been following experiences from people with more mileage on this, reporting Facebbok as an important router of traffic for this sales, and created an fb page for promoting GSFU, and other potential future assets:

If you're into #gameDev, give it a like, I promise not to bombard with too much marketing, but I like the idea that if you feel too invaded, you can simply unlike :)

Expanded

Finally solved the blog for the site. Was using internal Google Sites  systems that are not really for this purpose, and felt so clunky that I never used it.

Tumblr looks and feels slick and was really simple to tweak. Is not aesthetically finished -or at least not to the point I'd like- but with time, I will complete the transition.

For now, I feel happy to finally have this space functional!
