Beat the Clock

Part of the Physics and Gameplay section of Coddy's Unity journey. Lesson 31 of 63.

Challenge

Medium

Add the clock. Keep everything from the earlier steps, and add to Ball:

public float timeLimit = 60f; (the Inspector sets 30) and public float timeLeft;. Being public, timeLeft shows in the Inspector, where you can watch it count down.
When the game starts, timeLeft is timeLimit. Every frame while it is above 0, it goes down by the frame's time.
When it reaches 0, it stays at exactly 0, and the ball logs Time's up! Score: 5 once, with its score.
Once the time is up, the arrows no longer push the ball.

Press Play and see what you score in 30 seconds, then Check.

Try it yourself

using UnityEngine;

public class Ball : MonoBehaviour
{
    public float force = 10f;
    public int score;
    private Rigidbody rb;

    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    void FixedUpdate()
    {
        float x = Input.GetAxis("Horizontal");
        float z = Input.GetAxis("Vertical");
        rb.AddForce(new Vector3(x, 0f, z) * force);
    }

    public void AddScore(int points)
    {
        score += points;
        Debug.Log("Score: " + score);
    }
}
