I need help for spawning enemies in unity 2d
I have problem spawning enemies in unity 2d. Enemies clones themselves too quickly and it lags. Here's my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class EnemySpawner
{
public Transform[] spawnPoints;
public GameObject enemy;
public float spawnTime = 5f;
public float spawnDelay = 3f;
// Use this for initialization
void Start () {
InvokeRepeating ("addEnemy", spawnDelay, spawnTime);
}
void addEnemy() {
int spawnPointIndex = Random.Range(0, spawnPoints.Length);
Instantiate (enemy, spawnPoints[spawnPointIndex].position,
spawnPoints[spawnPointIndex].rotation);
}
}
I didn't type MonoBehaviour because it makes errors when I post this post.
Maybe you can use a coroutine to spawn ennemies, for me it's a better way to do it.
https://docs.unity3d.com/Manual/Coroutines.html
For example i'm using it to spawn ennemyes prefabs :
IEnumerator Spawner()
{
yield return new WaitForSeconds(spawnWait);
while (!stop)
{
int randSp = Random.Range(0, transform.childCount);
//Spawn Them
Instantiate(mb[randMb], new Vector3(Random.Range(-13f,13f), 0, 175), Quaternion.identity);
yield return new WaitForSeconds(spawnWait);
}
}
If you need to instantiate multiple prefabs and then destroy it better look at object pooling, it stacks the gameobject waiting for reuse it (ex : coins into a runner game) https://learn.unity.com/tutorial/object-pooling
Hope it can help you ;)
