how do i make the enemies spawn more freqent over time

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class enemySpawner : MonoBehaviour
6. {
7.     [SerializeField]
8.     private float spawnRadius = 7, time = 1.5f;
9.     public GameObject[] enemies;
10.     void Update()
11.     {
12.  
13.     }
14.     void Start()
15.     {
16.         StartCoroutine(SpawnAnEnemy());
17.     }
18.     IEnumerator SpawnAnEnemy()
19.     {
20.         Vector2 spawnPos = GameObject.Find("Player").transform.position;
21.         spawnPos += Random.insideUnitCircle.normalized * spawnRadius;
22.         Instantiate(enemies[Random.Range(0, enemies.Length)], spawnPos, Quaternion.identity);
23.         yield return new WaitForSeconds(time);
24.         StartCoroutine(SpawnAnEnemy());
25.     }
26. }
27.  

 

You could slowly start reducing the amount of time to wait to spawn the next enemy:

Code (CSharp):

1.     IEnumerator SpawnAnEnemy()
2.     {
3.         Vector2 spawnPos = GameObject.Find("Player").transform.position;
4.         spawnPos += Random.insideUnitCircle.normalized * spawnRadius;
5.         Instantiate(enemies[Random.Range(0, enemies.Length)], spawnPos, Quaternion.identity);
6.         Debug.Log($"Waiting {time} seconds before spawning the next enemy");
7.         yield return new WaitForSeconds(time);
8.         time *= .9f;
9.         StartCoroutine(SpawnAnEnemy());
10.     }

Adjust as desired.

 

thank you that really helped
