Match-3-Line-Drawer

Made with Unity 2018.2.18f1. The repository can be found in https://github.com/chulini/Match-3/

Software Architecture

Similar to a Model/View/Controller pattern the game architecture is splited in State/View/Logic class types. The communication between the different class types is using an event system.

(The event system was made using this tool https://github.com/chulini/unity-quick-events)

State Classes

State classes stores the current status of the game and sends events when relevant actions occurs. This classes are controlled only by Logic classes.

• GameState: Contains the state if the game like the current score, selected blocks, etc.
• BlockState: Contains the state of a block. The current colorID, if is selected, etc.
• BlockCoordinate: A struct that stores a (x,y) coordinate in discrete space

Logic Classes

Logic classes listen to the Views events and controls the State classes.

• Board: Listen to pointer events and implements the game logic updating the GameState

View Classes

View classes are in charge of listening to the game events and update the screen/audio. Some view classes sends input events.

• AudioEffects: Listen to game events and trigger audio
• Block: Updates the layout if a block listening to BlockState events
• BlockBgFallAnimation: Animates a the color of a block when falling to a new block
• BlockLineRenderer: Listen to game events and draws a line between selected blocks
• BlockPointerEvents: Sends mouse input events on a block
• UIManager: Listen to game events and updates the User Interface.
• UICanvasSwitcher: To fade between canvases.
• UIAnimatedText: To refresh a text making an animation.

Other Classes

• Game: The Main class that initializes the hole game.
• ExtensionMethods: Helper methods with math functions and shortcuts.

Scenes

As UIManager only listen to the game events and updates the UI elements. All the UI screens are made on an independent scene. When game starts Main scene loads UI scene additively.
