Case Of Murder Mystery + Hidden Object Game + Android Studio

Here's a comprehensive tutorial on creating a Case Of Murder Mystery + Hidden Object Game using Android Studio.

Introduction:

Welcome to this comprehensive tutorial on creating a Case Of Murder Mystery + Hidden Object Game using Android Studio. In this tutorial, we will be building a game that combines elements of detective work and hidden object hunting. The game will allow players to solve a murder mystery by collecting clues, interviewing suspects, and hidden objects.

The game will be developed using Android Studio, a popular integrated development environment (IDE) for Android app development. By the end of this tutorial, you will have a fully functional game that can be played on Android devices.

Step 1: Setting up the Game

To start, you will need to set up a new project in Android Studio. To do this:

1. Open Android Studio and click on the "Start a new Android Studio project" button.
2. Choose the "Empty Activity" template and give your project a name (e.g., "MurderMysteryGame").
3. Set the project location and choose the project type (e.g., "Mobile" and "Android").
4. Click on the "Next" button and then click on the "Finish" button to create the project.

Step 2: Creating the Game UI

The next step is to create the game UI. We will be using Android Studio's layout editor to design the UI. To do this:

1. Open the "activity_main.xml" file in the layout editor.
2. Add a "FrameLayout" to the screen by clicking on the "Layout" tab and selecting "FrameLayout".
3. Drag and drop a "RelativeLayout" inside the FrameLayout.
4. Add a "Button" inside the RelativeLayout by clicking on the "Widget" tab and selecting "Button". Name the button "searchButton".
5. Add a "EditText" field inside the RelativeLayout by clicking on the "Widget" tab and selecting "EditText". Name the EditText "searchEditText".
6. Add a "ListView" inside the RelativeLayout by clicking on the "Widget" tab and selecting "ListView". Name the ListView "clueList".
7. Add a "Spinner" inside the RelativeLayout by clicking on the "Widget" tab and selecting "Spinner". Name the Spinner "suspectSpinner".

Step 3: Creating the Game Logic

The next step is to create the game logic. We will be using Android Studio's code editor to write the game logic.

1. Open the "MainActivity.java" file and add the following code to the "onCreate()" method:

   
   // Initialize the search EditText
   searchEditText = (EditText) findViewById(R.id.searchEditText);

// Initialize the clue ListView clueList = (ListView) findViewById(R.id.clueList);

// Initialize the suspect Spinner suspectSpinner = (Spinner) findViewById(R.id.suspectSpinner);

// Set the onItemClickListener for the clue ListView clueList.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // Get the selected clue Clue selectedClue = (Clue) parent.getItemAtPosition(position);

    // Show the clue details in a Toast
    Toast.makeText(getBaseContext(), "Clue: " + selectedClue.getDescription(), Toast.LENGTH_SHORT).show();
}

});

// Set the onItemSelectedListener for the suspect Spinner suspectSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { // Get the selected suspect Suspect selectedSuspect = (Suspect) parent.getItemAtPosition(position);

    // Show the suspect details in a Toast
    Toast.makeText(getBaseContext(), "Suspect: " + selectedSuspect.getName(), Toast.LENGTH_SHORT).show();
}

@Override
public void onNothingSelected(AdapterView<?> parent) {
    // Do nothing
}

});

This code initializes the search EditText, clue ListView, and suspect Spinner. It also sets the onItemClickListener for the clue ListView and the onItemSelectedListener for the suspect Spinner.

**Step 4: Adding the Hidden Object**

The next step is to add the hidden object. We will be using Android Studio's code editor to create a new class for the hidden object.

1. Create a new Java class by clicking on the "File" menu and selecting "New" > "Java Class". Name the class "HiddenObject".
2. Add the following code to the "HiddenObject.java" file:
```java
public class HiddenObject {
    private String description;
    private int xCoordinate;
    private int yCoordinate;

    public HiddenObject(String description, int xCoordinate, int yCoordinate) {
        this.description = description;
        this.xCoordinate = xCoordinate;
        this.yCoordinate = yCoordinate;
    }

    public String getDescription() {
        return description;
    }

    public int getXCoordinate() {
        return xCoordinate;
    }

    public int getYCoordinate() {
        return yCoordinate;
    }
}

This code creates a new class for the hidden object with properties for the description, x-coordinate, and y-coordinate.

Step 5: Adding the Hidden Object to the Game

The next step is to add the hidden object to the game. We will be using Android Studio's code editor to create a new ArrayList of hidden objects.

1. Open the "MainActivity.java" file and add the following code to the "onCreate()" method:

   
   // Create a new ArrayList of hidden objects
   List<HiddenObject> hiddenObjects = new ArrayList<>();

// Add the hidden objects to the ArrayList hiddenObjects.add(new HiddenObject("Screwdriver", 10, 10)); hiddenObjects.add(new HiddenObject("Tire Iron", 20, 20)); hiddenObjects.add(new HiddenObject("Pliers", 30, 30));

// Initialize the game state gameState = new GameState();

// Add the hidden objects to the game state gameState.addHiddenObjects(hiddenObjects);

This code creates a new ArrayList of hidden objects and adds it to the game state.

**Step 6: Creating the Game State**

The next step is to create the game state. We will be using Android Studio's code editor to create a new class for the game state.

1. Create a new Java class by clicking on the "File" menu and selecting "New" > "Java Class". Name the class "GameState".
2. Add the following code to the "GameState.java" file:
```java
public class GameState {
    private List<HiddenObject> hiddenObjects;
    private int searchedArea;

    public GameState() {
        hiddenObjects = new ArrayList<>();
        searchedArea = 0;
    }

    public void addHiddenObjects(List<HiddenObject> hiddenObjects) {
        this.hiddenObjects = hiddenObjects;
    }

    public void searchArea(int searchedArea) {
        this.searchedArea = searchedArea;
    }

    public List<HiddenObject> getHiddenObjects() {
        return hiddenObjects;
    }

    public int getSearchedArea() {
        return searchedArea;
    }
}

This code creates a new class for the game state with properties for the hidden objects and searched area.

Step 7: Updating the Game State

The next step is to update the game state. We will be using Android Studio's code editor to update the game state in the "MainActivity.java" file.

1. Open the "MainActivity.java" file and add the following code to the "onSearchButtonClicked()" method:

   
   // Update the searched area
   gameState.searchArea(searchEditText.getText().toString());

// Check if the searched area contains any hidden objects if (gameState.getHiddenObjects().size() > 0) { // Display a Toast message Toast.makeText(getBaseContext(), "Hidden object found!", Toast.LENGTH_SHORT).show(); } else { // Display a Toast message Toast.makeText(getBaseContext(), "No hidden objects found.", Toast.LENGTH_SHORT).show(); }

This code updates the searched area and checks if the searched area contains any hidden objects. If there are hidden objects, it displays a Toast message; otherwise, it displays another Toast message.

**Conclusion:**

In this comprehensive tutorial, we have learned how to create a Case Of Murder Mystery + Hidden Object Game using Android Studio. We have created the game UI, added the hidden object, and created the game state. We have also updated the game state to search for hidden objects. With this game, players can solve a murder mystery by collecting clues, interviewing suspects, and hidden objects.
