Kindly help me with this player movement with left-right buttons

Finding a solution (not only in Unity) requires describing the problem. What do you see in the example?

  • Player left-right input set the game object into half circle movement.

Divide and conquer the problem, what do I need?

  • How to capture player left-right input?
  • How to translate player input into movement on a circle?
  • How to limit player input to move only half circle?

Now you know what you need. You can review your school mathematic knowledge a bit about sin and cos to do it yourself with full understanding or just by using proper questions to get answers right away from the Internet.

using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    public float moveSpeed = 5.0f; // Speed of movement
    public float rotationRadius = 2.0f; // Radius of the semicircle
    public bool limitToHalfCircle = true; // Flag to limit movement to half circle

    private float angle = 0.0f; // Current angle on the semicircle
    private Vector2 centerPoint; // Center point of the semicircle

    private void Start()
    {
        // Set the initial center point of the semicircle to the player's position
        centerPoint = transform.position;
    }

    private void Update()
    {
        // Get input from the player
        float horizontalInput = Input.GetAxis("Horizontal");

        // Update the angle on the semicircle based on player input
        angle += horizontalInput * moveSpeed * Time.deltaTime;

        // Check if we want to limit the movement to half circle
        if (limitToHalfCircle)
        {
            // Limit the angle to the range of -PI/2 to PI/2
            angle = Mathf.Clamp(angle, -Mathf.PI / 2.0f, Mathf.PI / 2.0f);
        }

        // Calculate the player's position on the semicircle
        Vector2 newPosition = new Vector2(
            centerPoint.x + Mathf.Cos(angle) * rotationRadius,
            centerPoint.y + Mathf.Sin(angle) * rotationRadius
        );

        // Move the player object to the new position
        transform.position = newPosition;
    }
}

Above code works and is limited for movement of the right side of a circle. So you need to find a solution how to get the other 3 half-circle limits.

Thank you so much. it’s working
