Trying to make a a script that spawns that spawns a prefab object-CodePudding

I have been trying to make a script that would drop prefabs at a random time in a random place in the y position so if anyone would be able to help me with this or tweak my code it would be greatly apprenticed

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

public class RainSpawn : MonoBehaviour
{
      public GameObject myPrefab;
    
     public float timeBetweenSpawn;

   void update(){
     timeBetweenSpawn = 1 - Time.deltaTime; 
     Instantiate(myPrefab, transform.position   Random.insideUnitSphere * 5, Quaternion.identity);
   }

}

CodePudding user response：

Hmm, wow there is a lot of explaining here. Welcome to Unity... er, welcome to programming!

You need to have Update be capitalized for it to be recognized as the Unity update loop.
Also, you want to subtract Time.deltaTime from time between.. not from 1.
Also, you want to make sure timeBetween is initialized to non-zero, perhaps using Random.Range().
not sure what u mean by random place in the y position.. as you are using random position in a sphere,

Try this:

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

public class RainSpawn : MonoBehaviour
{
      public GameObject myPrefab;
    
      public float minTime = 1f;
      public float maxTime = 5f;
      public float timeBetweenSpawn = 1f;

      void Start(){
        timeBetweenSpawn = Random.Range(minTime,maxTime);
      }

   void Update(){
     timeBetweenSpawn -= Time.deltaTime; 

     if(timeBetweenSpawn<0){
        Instantiate(myPrefab, transform.position   
             Random.insideUnitSphere * 5, Quaternion.identity);
         timeBetweenSpawn = Random.Range(minTime,maxTime);
     }
   }

}
