Learn to spawn a prefab instance at runtime with Instantiate.
Creating Prefabs with Instantiate
The Instantiate method creates a copy of an object at runtime. By passing a Prefab reference to Instantiate, you can add a new GameObject to the scene. This method is commonly used to spawn enemies, projectiles, rewards, or effects.
Instantiate(objectPrefab);Setting Position and Rotation
Overloaded versions of Instantiate allow you to specify the position and rotation of the object being created. You can use a Vector3 for the position and Quaternion.identity for the default rotation. This creates the object at the coordinates you choose.
Instantiate(objectPrefab, spawnPosition, Quaternion.identity);Practice Spawn an Object at Runtime
Check the objectPrefab asset assigned through the Inspector in the Start method. If the asset exists, create a new instance at spawnPosition with the default rotation and print a message to the console.
Starter code
using UnityEngine;
public class RuntimeSpawner : MonoBehaviour
{
public GameObject objectPrefab;
public Vector3 spawnPosition;
void Start()
{
}
}Sample solution
using UnityEngine;
public class RuntimeSpawner : MonoBehaviour
{
public GameObject objectPrefab;
public Vector3 spawnPosition;
void Start()
{
if (objectPrefab != null)
{
GameObject spawnedObject = Instantiate(objectPrefab, spawnPosition, Quaternion.identity);
Debug.Log("Yeni nesne üretildi: " + spawnedObject.name);
}
}
}Expected output
Yeni nesne üretildi: Crate
