在场景Unity中未检测到输入。 从该场景开始游戏时有效； 否则不起作用

Question

I'm currently working on a game where the start screen is level 0, the actual playable levels are levels 1-4, and the lose screen is level 5. My issue is with the lose screen. Here's my code:

void Update () {

    if(Input.GetKeyDown(KeyCode.Return) && (CurrentLevel == 0)){
        CurrentLevel = 1;
        Application.LoadLevel (CurrentLevel);
    }

    if (CharacterMovement.Score == 10) {
        CurrentLevel = 2;
        CharacterMovement.Score = 11;
        Application.LoadLevel (CurrentLevel);

    }

    if (CharacterMovement.Lives == 0) {
        isLost = true;
        Debug.Log ("is now true");
        CurrentLevel = 5;
        Debug.Log ("current level is set to 5");
        Application.LoadLevel (CurrentLevel);
    }

    if (CurrentLevel == 5) {
        Debug.Log ("this is level 5");
        if (Input.GetKeyDown(KeyCode.Tab)) {
            Debug.Log ("tab is pressed");

        }
    }
}

When I lose all of my lives I'm properly sent to the lose screen, and I receive the following logs from Debug.Log : "is now true", "current level is set to 5", and "this is level 5." However, when I press tab on the lose screen, I never receive the log "Tab is pressed". This is important because I want to be able to reset the game to the start screen when the key is pressed.

The weird thing is that if I press play from the lose screen in the Unity editor and hit tab, it works perfectly. But if I play through again and lose all my lives and try to hit tab, it doesn't work again.

What's going on here?

When you lose the game and load scene 5, Your Lives still are zero, so CharacterMovement.Lives == 0 will be true and you just load scene 5 repeatedly. If you look at your console I guess there is a lot of this is level 5 in that. You have to handle this situation.

You can do something like this:

void Update () {

    if(Input.GetKeyDown(KeyCode.Return) && (CurrentLevel == 0)){
        CurrentLevel = 1;
        Application.LoadLevel (CurrentLevel);
    }

    if (CharacterMovement.Score == 10) {
        CurrentLevel = 2;
        CharacterMovement.Score = 11;
        Application.LoadLevel (CurrentLevel);

    }

    if ((CurrentLevel != 5) && (CharacterMovement.Lives == 0)) { // Change this
        isLost = true;
        Debug.Log ("is now true");
        CurrentLevel = 5;
        Debug.Log ("current level is set to 5");
        Application.LoadLevel (CurrentLevel);
    }

    if (CurrentLevel == 5) {
        Debug.Log ("this is level 5");
        if (Input.GetKeyDown(KeyCode.Tab)) {
            Debug.Log ("tab is pressed");

        }
    }
}
