Hi, episode 8 of mobile game tutorial is available now. In this episode I will show you how to spawn our collectible objects created in previous episodes:

CODE:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ObjectSpawner : MonoBehaviour
{
    public GameObject[] objectsToSpawn;
    public int dstBetweenObjects;
    int lastObjectSpawnedPosition;
    public Transform rocketPosition;
    // Start is called before the first frame update
    void Start()
    {
        lastObjectSpawnedPosition = 0;
    }

    // Update is called once per frame
    void Update()
    {
        if (lastObjectSpawnedPosition <= rocketPosition.position.y)
        {
            SpawnObject();
        }
    }

    public void SpawnObject()
    {
        Vector2 spawnPos = new Vector2(RandomPosX(), lastObjectSpawnedPosition + dstBetweenObjects);
        lastObjectSpawnedPosition = (int)spawnPos.y;
        Instantiate(objectsToSpawn[RandomObject()], spawnPos, transform.rotation);
    }

    public int RandomPosX()
    {
        int x = 0;
        x = Random.Range(-2, 3);
        return x;
    }
    public int RandomObject()
    {
        
        int minRndRange = 0;
        int maxRndRange = objectsToSpawn.Length; // 0 - 3
        int rndValue = Random.Range(minRndRange, maxRndRange);
        return rndValue;

    }
}
