Welcome, fellow Unity developers! Today, we delve into the heart of Unity3D’s latest innovation – its new input system. This tutorial is designed to empower you with the skills to harness this powerful tool, transforming your gaming experiences.

Why the New Input System Matters

Unity’s new input system offers a more flexible and efficient way to handle user inputs. It simplifies complex scenarios, improves performance, and opens up new possibilities for interactive design. As Unity evangelist John Graham put it, “The new input system is a game-changer.”

Getting Started

To begin, let’s create a new project and navigate to the Input section in the Package Manager. Install the ‘Input System’ package, and you’re ready to go!

Building Your First Input Action

An input action represents a user’s interaction with the game, such as pressing a key or moving a joystick. To create an action, right-click in the Project window, select ‘Create > Input Actions,’ and name it accordingly.

Binding Input Devices

Next, we bind our input devices to the actions. In the Inspector window, you’ll find your newly created action. Click on ‘Add Binding,’ choose a device (e.g., Keyboard), and assign a key.

Creating an Input Action Map

An input action map groups multiple actions together, allowing for more complex interactions. To create one, right-click in the Project window, select ‘Create > Input Action Maps,’ name it, and add your actions.

Using the New Input System in Your Game

Now that we’ve set up our input system, let’s use it in a game. In the Update() function, we can now access our input actions through the Input class. For example, to check if the player is pressing the jump key:

csharp
if (Input.GetAction("Jump").ReadValue() > 0.5f)
{
// Jump code here!
}

Exploring Advanced Features

The new input system offers advanced features like dead zones, axis remapping, and user-defined modifiers. Experiment with these to create truly unique gaming experiences.
