Controller/gamepad support in Unity - Mini Project: Build & Apply

Controller/Gamepad Support in Unity

📖 Scenario: You are making a simple Unity game where the player can move a character using a gamepad or controller. You want to read the controller's joystick input to move the character smoothly.

🎯 Goal: Build a Unity script that reads the horizontal and vertical axes from a gamepad's joystick and moves a character accordingly.

📋 What You'll Learn

Create a Vector2 variable to store joystick input

Create a float variable for movement speed

Use Unity's Input.GetAxis method to read 'Horizontal' and 'Vertical' axes

Move the character's position based on joystick input and speed

Print the current joystick input values to the console

💡 Why This Matters

🌍 Real World

Many games use controllers for player input. Reading joystick axes lets players move characters naturally.

💼 Career

Game developers often implement controller support to make games playable on consoles and with gamepads.

1

Create a Vector2 variable for joystick input

Create a Vector2 variable called joystickInput and set it to Vector2.zero.

Unity

using UnityEngine;

public class PlayerController : MonoBehaviour
{
    // Your code here
}

Need a hint?

Use Vector2 joystickInput = Vector2.zero; to create a variable that starts with no input.

2

Add a float variable for movement speed

Add a float variable called moveSpeed and set it to 5f.

Unity

using UnityEngine;

public class PlayerController : MonoBehaviour
{
    Vector2 joystickInput = Vector2.zero;
    // Your code here
}

Need a hint?

Use float moveSpeed = 5f; to set how fast the character moves.

3

Read joystick input in Update method

Add an Update() method. Inside it, set joystickInput.x to Input.GetAxis("Horizontal") and joystickInput.y to Input.GetAxis("Vertical").

Unity

using UnityEngine;

public class PlayerController : MonoBehaviour
{
    Vector2 joystickInput = Vector2.zero;
    float moveSpeed = 5f;

    // Your code here
}

Need a hint?

Use Input.GetAxis("Horizontal") and Input.GetAxis("Vertical") to read joystick movement.

4

Move the character and print joystick input

Inside Update(), move the character by adding transform.Translate(joystickInput * moveSpeed * Time.deltaTime). Then print the joystick input using Debug.Log(joystickInput).

Unity

using UnityEngine;

public class PlayerController : MonoBehaviour
{
    Vector2 joystickInput = Vector2.zero;
    float moveSpeed = 5f;

    void Update()
    {
        joystickInput.x = Input.GetAxis("Horizontal");
        joystickInput.y = Input.GetAxis("Vertical");
        // Your code here
    }
}

Need a hint?

Use transform.Translate() to move the character and Debug.Log() to print the joystick values.
