Unity Wont Start “Sorry, this link is no longer valid”

Unity Wont Start “Sorry, this link is no longer valid”

How frustrating Unity isn’t starting and telling you “Sorry, this link is no longer valid”? Not a helpful error either! This confused me the other day as Unity had been working flawlessly previously.  To make matters worse restarting the computer appeared to fix it, but just once and then it started again. So what is going on here? Well I had just installed Unity 2018 beta, and thought, oh well is must be a beta issue, but then Unity 2017 started doing it as well. The only thing that had changed as far as I was aware is that I wasn’t at home, and link no longer valid didn’t make much sense yet alluded to a issue with the internet. A quick peek at my firewall settings revealed that the Unity program is blocked when on a public network But I’m not on a public network, ah Windows! So to sort this out we are going to have to change the network type. There is more than one way to do this, but here’s how I went about it. Click on the start button and click the settings button   Next Select Network and Internet After that you’ll need to select […]

The Unity Prefab Waterfall

The Unity Prefab Waterfall

A place for everything, everything in its place. Benjamin Franklin That’s why we care about this technique, because otherwise without it we duplicate things in Unity – a lot. Then… We lose track of our project. Bugs appear everywhere. Builds swell to device-breaking sizes. We go a little crazy. … and then die! OK, I may be exaggerating just a little here, but in my experience creating some of the world’s biggest and best online courses on Unity I get to see what my 100s of thousands of students do right – and wrong. The Premise NOT premises, like a  building. And when a cloud provider offers you an “on-premise” solution then they’re dumb, they mean “on premises”. Man, who can use a dictionary these days! Anyway, I digress. When you sit at a computer typing, or using your mouse, think about how much value it’s even possible to create. If you type continually at am ambitious 80 words per minute, then you’re only creating about half a kilobyte per minute! You may create real value a little faster with the mouse, but I doubt it! So if you’re not recording video or audio, your project file shouldn’t be growing faster […]

What’s Your Procrastination Pattern And Why Do You Do It?

What’s Your Procrastination Pattern And Why Do You Do It?

Why do we sometimes procrastinate? You know, those times that we avoid getting things done. Why is it that at times we just cant ignore our distractions? The short-term excitement becomes more powerful than our long-term goals. In fact, why don’t we just go ahead and answer this question right now by seeing if there are any new episodes on Netflix… Oh, wait a minute, I didn’t mean to say that out loud. Ignore that last bit. Must.. stay… focused. Quick, we need a heading with some bold font… The Three Reasons That You Procrastinate Avoiding your work comes down to one (or all) of these three things: You don’t know WHAT to do. That is, you aren’t clear on your next task, you don’t have a To Do list, you haven’t mapped out your priorities. You don’t know HOW to do it. Some tasks are tough and you aren’t sure the best way to approach it, perhaps you’ve never done it before, perhaps you’ve done it previously but it hasn’t been very successful. You don’t WANT to do it. There’s nothing worst than sitting down to start work on something you hate, or something you “should” be doing but […]

How To Come Up With New Game Design Ideas For Your Game

How To Come Up With New Game Design Ideas For Your Game

Want to be a better game designer? Want to create more interesting games? If so, then lets discuss the Single-Attribute-Exploration-And-Expansion Technique… or, worded slightly less crappily, “Edgecraft” (as coined by marketing guru Seth Godin). What is Edgecraft? Edgecraft is the process identifying one attribute or quality of a thing (eg. your game) and exaggerating that quality until it is something new / fresh / amazing / WTF-ish. The idea is to push beyond “sensible” and find something that really stands out. Let’s apply that to your game. First, lets consider Exhibit A, a screenshot from the Unity RPG Course that Ben Tristem and I have been working on.   The game has the core building blocks of most RPGs – a Player Character that you control, enemies, combat, User Interface, hit points, storyline, and so on. The magic of using Edgecraft is to take each aspect, one at a time, and ask yourself, “how could I make this different, or unusual, or crazy?”. You can do this systematically by picking one aspect, then brainstorming on that topic. For example, consider Exhibit B… Arrow #1 is pointing at the player. Let’s dig into the player a bit. Step 1 – Brainstorming attributes […]

Why A-Star Pathfinding Sucks

Why A-Star Pathfinding Sucks

Looking to get a game character from A to B? Want it to work-out its own route around obstacles? This is called pathfinding, and everyone keep harping on about A* (said A star). This is an awesome technique, but it can also suck for beginners! Why? Because it’s much more complex and, in many simple cases, unnecessary. The table below shows how it stacks up against other pathfinding algorithms… As you can see, A* doesn’t win on all counts. Do you need movement cost – the ability to have areas where the character moves faster or slower like roads or swamps? Do you need blistering speed, or would 50% slower than A* be just fine? If the answer to these questions is no, and you’re just starting-out, why would you put yourself through the pain of learning A*? Apart from the added complexity of understanding and programming A*, there are some other ways in which it sucks. If you want to find a path from a start point to multiple possible end points, or from multiple start points to one end point (thing Defence Grid 2 or other RealTime Strategies), then A* sucks as it’s designed for point-to-point pathfinding. The […]

Farewell VR Course!

Those of you keen enough to notice may have seen the disappearance of the VR course from our Udemy portfolio. I’m sorry I didn’t write this post earlier to explain why. As long time students will know, we are constantly working to improve the quality of our teaching. While this is great because new courses keep getting better, it also means we have old courses that are not as good. VR was becoming one of these courses. So a few months back we made the decision to start retiring the course from the marketplace. We no longer feel this course offers students the best teaching and the fast evolving pace of the VR landscape has made much of its content outdated. Obviously we would love to spend the required time to update the course and completely rework its learning journey. However, we currently have other important projects we need to focus on such as the Complete Unity Developer 2.0 and the RPG course. I apologise for those of you who might have been planning to purchase the course in the near future. I hope you will understand our reasons and hold out for the time we revisit the subject.

Start Designing Your Game!

Start Designing Your Game!

In the Unity RPG Core Combat Creator course lecture, “Start Designing Your RPG”, our instructor Rick Davidson teaches us how to fill out a Game Design Document and shows us examples of different types of  game designs! In this blog I’m taking my inspiration from Rick’s lecture and my experiences with playing video games, and I’m going to share some thought provoking discussions about the game design process. A lot of this is based on my opinions, and there are so many game design techniques that I can’t cover them all in this. Study game design and learn all that you can, and please refer to Ben and Rick’s course, the Unity RPG Core Combat Creator, for more information about designing and programming an RPG (Role Playing Game).  Ben Tristem and Rick Davidson are awesome instructors! Instead of thinking about a Game Design Document as something that you have to fill out quickly, so that you can get something done, please think of it like this: Think of it as a manual or a map, which will help you focus on certain tasks and, in turn, help you develop your game. This framework and your experiences will help you decide […]

What Happens When Flappy Birds Eat Too Many Brussel Sprouts at Christmas…

What Happens When Flappy Birds Eat Too Many Brussel Sprouts at Christmas…

Game ideas can come from the strangest of places! Here, Unity student Pontus, shares his game dev journey to finally finishing a game… What’s your background? I work for ILM (Industrial Light & Magic) as a VFX artist, an exciting job which has allowed me to work on some great films. So why would I make something as silly as Flappy Fart? Well, I remember picking up a software around the age of 10 I believe, called The Games Factory, where you could put together very simple 2D games. The idea that I could make something that others could then play was a thrilling thought! I started making games like a mad person, I had so many projects going on I lost count, I loved it! And I finished zero projects… And as the years went by I started forgetting about the video game making dreams and decided to pursue a career in film instead, I had some basic understanding of editing and 3D softwares, it seemed like the right thing to do. Besides, the idea of programming in games was always daunting. It was only one day at work, years later, when a friend of mine mentioned an online […]

Unity Student Takes Block Breaker To Hiragana Level

Unity Student Takes Block Breaker To Hiragana Level

It’s awesome to see our students taking what they’ve learnt on our courses and using it to help other people learn. In this post we’re sharing John Gale’s story of how he came to create ‘Hiragana Breaker’ – a block-breaking game that helps you learn basic Japanese characters. What’s your background? My major in university was for audio recording with a minor in music. I have a Master’s degree in Japanese, a Japanese Language Proficiency Test (JLPT) Level 1 certification, and lived in Japan as an English teacher for almost four year. All of that was because of Japanese video games like Final Fantasy and Mega Man on the original NES. So yes, I have been into video games since I was a child. But growing up in the 80’s and 90’s before the Internet and YouTube were everywhere, I never made the connection that computer programming or designing games was something I could learn to do. It seemed so distant and disconnected from anything I was studying or pursuing as a career. Looking back now though, it’s something I could have done, been good at and had a successful career with. But thanks to the course I realize it’s […]
