Change Scene
To create a Unity script that transitions from one scene to another when a player collides with a specific game object, you’ll need to set up the following:
- Two scenes in your Unity project.
- A game object that will trigger the scene transition.
- A Collider component attached to the game object that triggers the transition, set as a trigger.
- The Unity Scene Management package to handle scene loading.
Here is a step-by-step guide to set this up, followed by the script:
Setup in Unity
- Create Scenes: Ensure you have at least two scenes in your Unity project. Let’s call them
Scene1
andScene2
. You can create new scenes by going toFile
>New Scene
and save them respectively. - Setup the Game Object to Trigger Scene Transition:
- Add a game object to
Scene1
that will act as the trigger. This could be a door, a portal, etc. - Add a Collider component to this object (like a
BoxCollider
orSphereCollider
) and make sure to check theIs Trigger
property on the Collider.
- Add a game object to
- Load Scene Management:
- Go to the Unity Editor, open the menu
Edit
>Project Settings
>Player
, and make sure that both scenes are included in the Scenes In Build list under theBuild Settings
.
- Go to the Unity Editor, open the menu
Now, write a C# script that performs the scene transition:
using UnityEngine;
using UnityEngine.SceneManagement;
public class SceneTransition : MonoBehaviour
{
public string targetSceneName = "Scene2"; // Name of the scene to load
void OnTriggerEnter(Collider other)
{
// Check if the collider belongs to the player
if (other.CompareTag("Player"))
{
LoadNextScene();
}
}
void LoadNextScene()
{
// Load the target scene
SceneManager.LoadScene(targetSceneName);
}
}
Attach the Script and Test
- Attach the Script:
- Attach the script to the same game object with the trigger collider.
- In the inspector, set the
Target Scene Name
to the name of the scene you want to load (e.g., “Scene2”).
- Tag the Player:
- Ensure that your player game object has the tag “Player”. You can set this by selecting the player object, going to the Inspector, and from the Tag dropdown, selecting “Player”.
- Testing:
- Enter Play mode in Unity and test by moving the player to collide with the trigger object. The scene should transition to
Scene2
when they collide.
- Enter Play mode in Unity and test by moving the player to collide with the trigger object. The scene should transition to
This script and setup should work perfectly for a basic scene transition on collision in Unity. Make sure that your scenes are properly set up and referenced, and that the player object correctly interacts with triggers.
