![]() ![]() The Input System provides the following types of controls out of the box: Control TypeĪ button expressed as a floating-point value. Most concrete implementations are based on InputControl. Control typesĪll controls are based on the InputControl base class. To access the flattened hierarchy of all Controls on a Device, use InputDevice.allControls. You can access the parent of a Control using InputControl.parent, and its children using InputControl.children. The setup of hierarchies is exclusively controlled through layouts. The root of a Control hierarchy is always a Device. Control hierarchiesĬontrols can form hierarchies. ![]() For example, the short display name for the left mouse button is "LMB". You can access the aliases for a specific Control through its InputControl.aliases property.įinally, a Control might also have a short display name which can be accessed through the InputControl.shortDisplayName property. For example, the right-hand face button closest to the touchpad on a PlayStation DualShock 4 controller has the control name "buttonWest" and the display name "Square".Īdditionally, a Control might have one or more aliases which provide alternative names for the Control. Output and configuration items on Input Devices are not represented as Controls.Įach Control is identified by a name ( InputControl.name) and can optionally have a display name ( InputControl.displayName) that differs from the Control name. The only requirement is that the type is blittable. These values can be of any structured or primitive type. If you’ve been working with Unity before, you probably already know how to use the old input system.An Input Control represents a source of values. I’m not going to repeat what you can read in the documentation, but rather highlight the main difference. The old versus the new Unity input systemīefore we start building our player controller, let’s briefly talk about the difference between the new and the old Unity input system. Speaking of design patterns, apart from the state pattern we’ll use also another one, in game development very common, if not the most common: the observer pattern. However, I will assume you have a basic understanding of C# and OOP concepts like inheritance and abstract classes.īy the end of this post, you’ll be able to easily extend our controller with your own states and you’ll have under your belt a design pattern you’ll find useful in many different contexts. In case you’ve never heard about state machines or the state design pattern before, fear not, I’ll explain everything step-by-step. We’re going to implement the core of the controller as a state machine with a focus on clean architecture and extendability. On top of that, you’ll see how to set up idle, run, jump, and fall animations and how to smoothly transition among them. Our third-person controller will handle inputs from a keyboard and mouse and a standard gamepad, and because the new input system in Unity is quite smart, as you’ll soon see, adding support for another input device wouldn’t require any extra code. ![]() In this post, I’ll show you how to build a third-person controller in Unity with the new Input System package together with a follow camera driven by Cinemachine, another powerful package by Unity Technologies. If you randomly pick a few games, each would probably have a different art style and mechanics, a different story, or even no story at all, but there’s one thing they’d all have in common: all games need to read and handle inputs from devices like keyboard, mouse, gamepad, joystick, VR controllers, and so on. Building a third-person controller in Unity with the new input system I work full-time as a programmer in Bohemia Interactive studio, in my spare time I write blog posts, occasionally create a game on a game jam, and constantly learn to be a better developer. Today, I'm fluent in C#, C++, and JavaScript, and I love making games. Marian Pekár Follow I'm a programmer by heart and soul. ![]()
