Can I use one script to toggle between scenes?
I have this script that I used to toggle the player between one scene and another scene. The script works by calling a function when a certain button is pressed (this function switches the scenes). Take a look:
public class ToggleScript : MonoBehaviour
{
public Transform normalPlayer;
// Update is called once per frame
void Update()
{
if (Input.GetKeyDown(KeyCode.Q))
{
ReloadScene();
}
}
public void ReloadScene()
{
SceneManager.LoadScene("AltScene");
if (Input.GetKeyDown(KeyCode.E))
{
LoadOrigional();
}
}
public void LoadOrigional()
{
SceneManager.LoadScene("NormalScene");
}
}
When I run this script, I start in "NormalScene" (as that's where the game starts). When I press Q, the game takes me to "AltScene" by calling the ReloadScene() function, but when I press E to take me back to "NormalScene" nothing happens. Can someone explain to me why this happens? On a side note, is there any way for me to make sure the player stays in the same positon (so if my player was at X-Coordinate 70 when I switch the scenes I want it to stay at X-Coordinate 70 when the scene is put on again. This issue is not the priority). Thank you so much for your help :)
you are reading for get key down for E in a one frame function, which means you need to press E and Q frame perfect simultaneous to make it work, which is very very difficult if not generally impossible...instead you should to do something like this
public class ToggleScript : MonoBehaviour
{
public Transform normalPlayer;
// Update is called once per frame
void Update()
{
if (Input.GetKeyDown(KeyCode.Q))
{
ReloadScene("Altscene");
}
else if(Input.GetKeyDown(KeyCode.E)
{
ReloadScene("NormalScene");
}
}
public void ReloadScene(string s)
{
SceneManager.LoadScene(s);
}
id also recommend you look into things like build indexes and GetActiveScene() which will make this a piece of cake...for example
void Update()
{
if(Input.GetKeyDown(KeyCode.Q) || Input.GetKeyDown(KeyCode.E))
{
LoadOther();
}
}
public void LoadOther()
{
Debug.Log("loading");
int i = SceneManager.GetActiveScene().buildIndex;
int n = 0;
if(i = 0)
{
n = 1;
}
SceneManager.LoadScene(n);
}
then you can assign the scenes in the build settings and you're good to go, the advantage with using build indexes is that it makes it really easy to build a system to work with any number of scenes for example levels in a game
You need to put the
if (Input.GetKeyDown(KeyCode.E))
{
LoadOriginal();
}
in the update method because once you call the reload scene then it checks for the key E once and then ends the function.
Side Note: I assume that this script is affected by DontDestroyOnLoad() function so you can get a reference to the player transform at awake and before you call the load functions, store the player's x in a variable and set the x to that variable's value with a new Vector3 once you travel to the new scene.
