  • Input Handling: Set up input handling to capture player controls. Unity’s Input system provides a convenient way to manage input. You can use the Input.GetAxis function to get horizontal and vertical input values, or use the Input.GetKey function to detect specific key presses.
  • Movement Script: Create a new C# script to handle the player’s movement. Attach the script to the player character’s GameObject. In the script, you’ll need to access the Rigidbody2D component and modify its velocity based on the input values.
using UnityEngine;

public class PlayerMovement : MonoBehaviour
    public float moveSpeed = 5f;
    private Rigidbody2D rb;

    private void Start()
        rb = GetComponent<Rigidbody2D>();

    private void Update()
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        Vector2 movement = new Vector2(moveHorizontal, moveVertical);
        rb.velocity = movement * moveSpeed;

In this example script, the “moveSpeed” variable determines the player’s movement speed. The Update method retrieves the input values, creates a movement vector, and sets the Rigidbody2D’s velocity accordingly.

  • Apply the Script: Attach the PlayerMovement script to the player character’s GameObject in the Unity Editor. Adjust the “moveSpeed” value to your desired speed.
  • Testing: Run the game and test the player movement. The character should move in response to the arrow keys or other configured input. Make adjustments to the movement speed or input settings as needed.
  • Animation Feedback (Optional): To add visual feedback to the player’s movement, you can create animations for walking, running, or idle states.

    public float moveSpeed = 5f;
    private Animator animator;
    private Rigidbody rb;

    private void Start()
        animator = GetComponent<Animator>();
        rb = GetComponent<Rigidbody>();

    private void Update()
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        Vector3 movement = new Vector3(moveHorizontal, 0f, moveVertical) * moveSpeed;
        rb.velocity = movement;

        float speed = Mathf.Abs(moveHorizontal) + Mathf.Abs(moveVertical);
        animator.SetFloat("Speed", speed);

In this example script, the “moveSpeed” variable determines the player’s movement speed. The Update method retrieves the input values, applies movement to the Rigidbody component, and sets the “Speed” parameter in the Animator component.

  • Assign Animation Clips: Drag and drop the animation clips onto the respective animation states in the Animator window. Ensure that each animation clip corresponds to the desired movement, such as walking, running, jumping, etc.
  • Testing: Run the game and test the player movement. The character should now play animations based on the player’s movement input. Make adjustments to animation transitions, speed thresholds, or other parameters to achieve the desired visual effect.
