Faster and Faster

Part of the Unity Scripting Basics section of Coddy's Unity journey. Lesson 54 of 85.

Challenge

Medium

Make every catch speed up the stars.

Add [SerializeField] private float speedUp = 0.5f;.
In the catch's if, next to score++;, add fallSpeed += speedUp;. Not in ResetStar(): misses call it too.

Press Play and catch a few: each star falls faster. 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;
    private int score;

    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;

        if (Vector3.Distance(transform.position, star.position) < 1f)
        {
            score++;
            Debug.Log("Caught! Score: " + score);
            ResetStar();
        }
        else if (star.position.y < 0f)
        {
            ResetStar();
        }
    }

    void ResetStar()
    {
        star.position = new Vector3(Random.Range(-4f, 4f), 6f, 0f);
    }
}
