TetraMaster with SwiftUI

About the project:

I chose Final Fantasy IX's Tetra Master to look into SwiftUI the new method to build UI for apple devices (somewhat replacing/supplementing storyboards). To get the original feel of the in-game version I used many original resources. According to https://www.jp.square-enix.com/caution.html Square Enix seems to be very restrictive about copyright infringements, so I stripped the code of all resources including images and sound that are from the original game.

Basic facts about the game:

• Matchmaking and battles were inspired by the original (paper) Card Game
• The player can choose 5 out of 9 random cards and can reshuffle the given cards if needed
• The computer gets 5 random cards
• The beginner of every match is set randomly
• The player can flip the computers cards to get an advantage
• The player can rematch after a game or reset to the starting screen

Key Lessons learned:

• SwiftUI in general
• Structs and Views
• Publishing to GitHub directly from Xcode
• The quirks of and how to use the geometry reader in multiple layers of views

Open Points:

The game is in a playable state but of course I could add endless features to it. Here are some I thought about:

Game:

• Give the computer more brainpower especially at start and according to the values of the card
• Add random blocked fields like in the original game
• Upgrade the battle animation between cards
• Find higher resolution cards to play with
• Build a higscore list to track previous games
• Find a more suitable background than just black color
• Find a better solution for triangles and placing on cards

Technical/Coding side:

• Some basic refactoring
• Sort out optionals and remove left force unwrappings
• Find a logic for multiple device sizing with Geometry Reader
• Find a better/modified solution for timing than „DispatchQueue.main.asyncAfter“
