Biarkan Balok Jatuh

Termasuk bagian Dasar-Dasar Scripting Unity dalam perjalanan Unity di Coddy. Pelajaran 77 dari 85.

Tantangan

Sedang

Buat setiap block dalam list jatuh. Pertahankan semua yang sudah dibuat pada langkah sebelumnya.

Tambahkan [SerializeField] private float fallSpeed = 5f;.
Di akhir Update(), lakukan perulangan dengan foreach (GameObject block in blocks).
Di dalamnya, tambahkan Vector3.down * fallSpeed * Time.deltaTime ke block.transform.position.

Tekan tombol “Main”: block berjatuhan melewati pelari. Lalu tekan tombol “Periksa”.

Coba sendiri

using System.Collections.Generic;
using UnityEngine;

public class Runner : MonoBehaviour
{
    [SerializeField] private float speed = 6f;
    [SerializeField] private float laneEdge = 4f;
    [SerializeField] private GameObject blockPrefab;
    [SerializeField] private float spawnEvery = 1f;

    private List<GameObject> blocks = new List<GameObject>();
    private float timer;

    void Update()
    {
        Vector3 p = transform.position;
        p.x += Input.GetAxisRaw("Horizontal") * speed * Time.deltaTime;
        p.x = Mathf.Clamp(p.x, -laneEdge, laneEdge);
        transform.position = p;

        timer += Time.deltaTime;
        if (timer >= spawnEvery)
        {
            timer -= spawnEvery;
            Vector3 spot = new Vector3(Random.Range(-laneEdge, laneEdge), 10f, 0f);
            blocks.Add(Instantiate(blockPrefab, spot, Quaternion.identity));
        }
    }
}
