Unity Prefabs are a powerful yet often confusing system. In this tutorial I explain everything you need to know about using them. This is the first of a new game dev lecture / classroom series. Topics covered in this video include: workflow examples, nested prefabs, unpacking prefabs, editing master and instances. […]
In this post I will demonstrate a solution to the common problem of slipping off moving platforms in Unity when using RigidBody game objects. The problem can be encountered in both 2D and 3D games, I will cover two known solutions I have come across, and explain in detail the solution I have applied in the game [...]
In this tutorial I will explain how to create a realistic looking smoke effects in Unity. It will be your typical upwards smoke, which is ideal for camp-fires, smoky car engines. Basically anything that burns. It's also an effective way to simulate steam (for both 2D and 3D games). Unity uses what is called the 'Shuriken' [...]
Recently I have been working on a 2D platformer which uses the inbuilt Unity Physics and Rigidbodies. One of the challenges I ran into was that when the player moved above a certain velocity, it would sometimes pass through colliders. This would lead to the player getting stuck inside the floor when landing a from a [...]
I've been tinkering with Unity's 2D tooling since it was officially released in v4.3. With each new version we see some improvements in the 2D tools and workflow, but alas it's far from perfect and as a result getting things to work the way you want is all about trial and error. One thing I have learnt quickly [...]
Unity's button / Input system has been the source of confusion for many newcomers. It's no suprise, after all we have GetKey, GetKeyDown, GetKeyUp, GetButton, GetButtonDown, GetButtonUp. So let's try make sense of it all. GetKey / GetKeyDown / GetKeyUp Input.GetKey(...) will be familiar to developers coming from other platforms like Flash. It accepts either a KeyCode parameter [...]
It's been a little while now since I wrapped up my last tutorial series, and I want to thank the readers who shared it around Twitter and sent me personal thanks. I love hearing how something I wrote helped somebody better their skills. We have all been there and are upgrading every day! So, to keep [...]
This is the 3rd and final installment in the mini tute series 'Creating 2D Animation States in Unity3D' . You can find previous installments here: Part1 | Part 2 In part 2 we created our Player animations, created an animation controller, organised our animations in the Animator window, and then mapped them to 'Conditions' based on [...]
This post is part 2 of Understanding and Creating 2d Animation State management in Unity3d, In this tutorial we will be continuing from Part 1 and covering the following topics: Adding the player component Adding an animation State Manager to the player Defining Animation transition rules and parameters Switching between animations at runtime Ok so lets get [...]
Inheritance is an Object Oriented Programming concept (OOP) used to access and reuse the properties or methods of one class from another. The class being inherited from is known as the 'base' class, where the one inheriting from the base class is known as the 'derived' class. Let's think of it like this: John (derived class), is [...]
