How can objects be copied in bulk in Unity?

In Unity, you can use code to duplicate objects in bulk. Below is an example script that can copy an object multiple times.

using UnityEngine;

public class ObjectDuplicator : MonoBehaviour
{
    public GameObject objectToDuplicate; // 需要复制的物体
    public int numberOfDuplicates; // 复制的数量
  
    private void Start()
    {
        for (int i = 0; i < numberOfDuplicates; i++)
        {
            GameObject newObject = Instantiate(objectToDuplicate);
            newObject.transform.position = new Vector3(i * 2, 0, 0); // 每个物体的位置偏移
        }
    }
}

In the example above, we first create a variable called objectToDuplicate, which is a reference to the object we need to duplicate. Then, we create a variable called numberOfDuplicates, which determines the quantity of copies needed.

In the Start method, we use the Instantiate function to duplicate objects in the scene. We can then use newObject.transform.position to set the position of each duplicate object so they are correctly arranged in the scene.

Attach the above script to an empty game object, and set the objects to be duplicated and the quantity of copies needed in the script’s public variables. When you run the game, you will see multiple replicated objects in the scene.
