Design and Code Your Own C# Slot Machine Game

Coding the Core of Your C# Slot Machine Game

Now it’s time to dive into the heart of your project: the code. We'll create a single C# script named GameManager to manage our game logic.

Creating the GameManager Script

1. Navigate to your Assets folder.

2. Right-click and select Create > C# Script.

3. Name the script GameManager.

• Bonus tip: A script named GameManager gets a special icon in Unity, making it easier to identify.

Setting Up the GameManager GameObject

1. Create an empty GameObject in the hierarchy and name it GameManager.

2. Attach the GameManager script to this GameObject.

• Serialized Variables:

• boardHeight and boardWidth represent the size of the game board.

• gamePieces is an array of the icons that can spawn on the board.

• The [SerializeField] tag allows private variables to be set in the Unity Inspector without exposing them publicly.

• Private Variables:

• _board holds the GameBoard object from the scene.

• _gameBoard is a 2D array representing the spawned icons.

• _offset adjusts the Z-position of spawned objects to ensure proper layering.

• Instantiate:

• Spawns a random game piece from gamePieces.

• Uses slot.transform.position + _offset to ensure the icon appears in front of the slot.

• Naming Convention:

• Slots are named based on their array position, e.g., "0 0" for the first slot.

Adding a Spin Button

1. Right-click in the Hierarchy and select UI > Legacy > Button.

• Unity will automatically add a Canvas and EventSystem to your scene.

2. Adjust the Canvas to fit your desired UI layout.

3. Place the button in the lower-right corner (or wherever you prefer).

4. Change the button’s text to “SPIN”.

Wiring the Button to the Spin Method

1. In the On Click section of the button's Inspector:

• Press the + button.

• Drag your GameManager GameObject to the empty field.

• Select the Spin method from the dropdown.

Testing Your Game

When you press the Spin button, it should generate a new set of icons each time. Ensure the icons spawn in their correct positions and are layered properly.

With these steps, your basic slot machine game logic is complete. You can now expand on this foundation with animations, sound effects, or additional gameplay mechanics!
