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
Navigate to your Assets folder.
Right-click and select Create > C# Script.
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
Create an empty GameObject in the hierarchy and name it
GameManager
.Attach the
GameManager
script to this GameObject.
Serialized Variables:
boardHeight
andboardWidth
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
Right-click in the Hierarchy and select UI > Legacy > Button.
Unity will automatically add a Canvas and EventSystem to your scene.
Adjust the Canvas to fit your desired UI layout.
Place the button in the lower-right corner (or wherever you prefer).
Change the button’s text to “SPIN”.
Wiring the Button to the Spin Method
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!
