Player No Longer Moving

Coding the scene transitions has caused the player to stop moving. I also get this error when running: Cannot load scene: Invalid scene name (empty string) and invalid build index -1 UnityEngine.SceneManagement.SceneManager:LoadScene (string) SceneTransition:OnTriggerEnter2D (UnityEngine.Collider2D) (at Assets/SceneTransition.cs:32)

What do I need to upload to get help?

Please upload your SceneTransition script, specifically the part where you define the transitionTo variable, and any relevant settings in the Unity Editor related to scene management.

    {
        PlayerController.Instance.transform.position = startPoint.position;

        StartCoroutine(PlayerController.Instance.WalkIntoNewScene(exitDirection, exitTime));
    }

{
    if(_other.CompareTag("Player"))
    {
        GameManager.Instance.transitionedFromScene = SceneManager.GetActiveScene().name;

        PlayerController.Instance.pState.cutscene = true;

        SceneManager.LoadScene(transitionTo);
    }
}

}

Thank you for sharing your SceneTransition script. The error message you’re seeing indicates that the transitionTo string is either empty or not properly set when you attempt to load the scene. Here are a few things to check and some suggestions to help you debug the issue:

1. Check Scene Name in Inspector: Make sure that you have assigned a valid scene name to the transitionTo variable in the Unity Inspector for the object that has this SceneTransition script attached. If it’s empty, you’ll receive the “Invalid scene name” error.

2. Build Settings: Ensure that the scene you are trying to load is included in the build settings. Go to File -> Build Settings and check if the scene is listed there. If not, add it to the list.

3. Debug Log: Add a debug log statement before the SceneManager.LoadScene(transitionTo); line to see what value transitionTo holds when the trigger is entered:

   Debug.Log("Transitioning to scene: " + transitionTo);

4. Check GameManager: Ensure that the GameManager.Instance.transitionedFromScene is correctly set and that it doesn’t interfere with the logic in the Start() method. If it’s affecting the scene transition logic, it might be worth checking how and when it’s being set.

5. Player Movement: If the player is stopping after the transition, ensure that the player’s state is being managed properly. The line PlayerController.Instance.pState.cutscene = true; might be causing the player to stop moving if your player controller logic pauses movement during a cutscene.

6. Scene Names: Double-check for any typos in the scene name you are trying to transition to, both in the script and in the Unity Editor.

Once you go through these steps, you should be able to identify the issue. If you still encounter problems, please provide any additional error messages or behavior you’re observing.

None of it is working still. I no longer want to include scene transitions to the game. I’m happy with a singular scene the player has to fight and work through. Will that affect death and respawn in the future

If you decide to have a single scene for your game, it won’t inherently affect the death and respawn mechanics as long as you implement those systems correctly within that scene. Here are a few considerations to keep in mind:

1. Player Death Handling: You can implement a player death system where, upon dying, the player’s health is reset, or they are moved back to a specific spawn point within the same scene.

2. Respawn Point: You can define a respawn point in your scene. When the player dies, you can reset their position to this respawn point instead of loading a new scene.

3. Game Over Screen: You might want to consider implementing a game over screen or a similar mechanic that allows the player to restart the game or return to a checkpoint.

4. State Management: Ensure you manage the player’s state effectively. For example, when the player dies, set their state to “dead” and disable controls until they respawn.

5. Persistent Data: If you plan on having levels or progress that need to be saved, consider how you can manage that data within a single scene.

If you need help with implementing a respawn system or any specific mechanics in your game, feel free to ask!

Is there any other reason my player still won’t move when playing? I’ve fully delete all of the scene transition material and I still can’t get movement

There could be several reasons why your player is still not moving. Here are some things to check:

1. PlayerController Script: Ensure that the PlayerController script is correctly attached to your player GameObject and that there are no errors in the script that would prevent it from executing.

2. Input Settings: Verify that your input settings in Unity are correctly configured. Check if the “Horizontal” axis is set up in the Input Manager.

3. Rigidbody2D Settings: Make sure that the Rigidbody2D component on your player is not set to “Kinematic” and that its constraints are not preventing movement.

4. Animator State: If you are using an Animator, ensure that the animations are set up correctly and that the “Walking” parameter is being set properly in the PlayerController script.

5. Ground Check: If your movement relies on the Grounded() method, ensure that the ground check logic is functioning correctly and that the player is detected as grounded.

6. Debugging: Add debug logs in your Update() method to check if the GetInputs() and Move() methods are being called and if the xAxis variable is being updated.

If you’ve checked all of these and the player still won’t move, could you provide more details about your player GameObject setup and any relevant components attached to it?
