Scenes

• We can refer to them as levels
• Add The scenes in Build Settings
  • Ctrl + Shift + B > Add Open Scenes
    • We can see the indexes of the scenes
• SceneManager (class in Unity)
  • https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.html

• When we hit an abstacle, we can “respawn” back to the starting by stopping the scene and loading the current scene again.

void NextScene(){
	// levelling up until the last scene (then we repeat)
	int nextLevelIndex = SceneManager.GetActiveScene().buildIndex + 1;
	int indexToLoad;
 
	if (nextLevelIndex == SceneManager.sceneCountInBuildSettings)
	{
		indexToLoad = 0;
	} 
	else {
		indexToLoad = nextLevelIndex;
	}
	SceneManager.LoadScene(indexToLoad);
}
 
void ReloadScene(){
	// Calling this function when we hit an obstacle 
	int currentIndex = SceneManager.GetActiveScene().buildIndex;
	SceneManager.LoadScene(currentIndex);
}

void NextSceneSequence() 
{
	// because this is set to true, even though OnCollisionEnter is 
	// called again it will just return
	isTransitioning = true;
	audioSource.Stop();
 
	// effects
	audioSource.PlayOneShot(success);
	successParticle.Play();
 
	GetComponent<Movement>().enabled = false;
	Invoke("LoadNextScene", delaySeconds);
}
void CrashSequence() 
{
	isTransitioning = true;
	audioSource.Stop();
 
	// effects
	audioSource.PlayOneShot(collision);
	crashParticle.Play();
 
	// "Movement" is a script I made for the Rocket
	GetComponent<Movement>().enabled = false;
	Invoke("ReloadScene", delaySeconds);
 
	// GetComponent<Movement>().enabled = true;
	// No need to include this line because the ReloadScene overwrites this
}
