Catch It

Part of the Unity Scripting Basics section of Coddy's Unity journey. Lesson 52 of 85.

Challenge

Medium

Catch the star and count the catches.

Add a field private int score;.
After the star moves, when Vector3.Distance(transform.position, star.position) < 1f, add 1 to score and log "Caught! Score: " + score.
In that if, move the star back to y = 6f, keeping its x and z.

Press Play and slide under the star: the Console shows Caught! Score: 1. Then Check.

Try it yourself

using UnityEngine;

public class Catcher : MonoBehaviour
{
    [SerializeField] private float speed = 6f;
    [SerializeField] private Transform star;
    [SerializeField] private float fallSpeed = 3f;

    void Update()
    {
        float x = transform.position.x;
        if (Input.GetKey(KeyCode.RightArrow))
        {
            x += speed * Time.deltaTime;
        }
        if (Input.GetKey(KeyCode.LeftArrow))
        {
            x -= speed * Time.deltaTime;
        }
        x = Mathf.Clamp(x, -4f, 4f);
        transform.position = new Vector3(x, transform.position.y, transform.position.z);

        star.position += Vector3.down * fallSpeed * Time.deltaTime;
    }
}
