If a piece can take an enemy piece, then a blue square will appear over the enemy piece. When the player selects a chess piece, the valid moves for that piece will be displayed as blue squares on the chessboard. If a player's timer goes to zero, they automatically lose. When each player makes a move, their timer will stop and the other player's timer will begin counting down again. If there is a timer, the timer for player 1 (white pieces) will immediately begin. There will also be a status message in the middle of the screen describing whose turn it is. For two-player games, each player's name, profile picture, and the time left is displayed on either side of the screen. In one-player mode, there will be a status message that is displayed that will either display 'Your Turn' if it is the player's turn to go, or 'AI Is Thinking.', which is displayed while the AI is trying to make its move. Clicking this button will bring up the chessboard view. Once all players have been selected, the 'Start' button on the main menu will become enabled. Keep in mind that if you delete a player, all saved games the player is associated with will also be deleted. The reset and delete actions will bring up a warning action to make sure the user is certain about their action.

The user must add a name and can optionally add a profile picture from their phone. If you plan on playing two-player games, two user profiles must be created. When the app initially starts, there will be no player profiles yet, so the user will need to add at least one if you plan on playing with an AI. The available options for time limits are Unlimited, 30min, 60min, 90min, 120min, and 150min.īy clicking on the 'Select Player' button for each player, users will be brought to a player selection screen with all available player profiles.

This option allows you to set the time limit for the game. If you select the two-player game mode, one additional game option will appear. The second option lets you choose which side you want to play on (Black or White). The first allows you to change the difficulty of the AI that you play with (Easy, Normal, or Hard). If you select one player, two other options will appear. Here you can select how many players you want to play with. When the app first starts, you will be shown the main menu. This app was developed mainly using the iPhone SE 2nd Gen simulator, but should also work for other iPhone models. Simply load the project into Xcode and build it normally. This app does not require any external dependencies to work. Despite having little actual chess skill, I still felt that this would be a fun project to attempt. I decided to create a chess app after being inspired by the Netflix show The Queen's Gambit. We were tasked with created an app of our choosing to develop over a 5-week period. I created this app as my final project for my application development class at Penn State (CMPSC 475). Timed games (For two-player games only).castling while in check) and has been fixed in En Passant.Ĭheckmate is a chess app programmed using SwiftUI, Core Data, and SpriteKit. Please note that Checkmate's chess engine is slightly incorrect (e.g. The recreation is called En Passant, and is available on both Google Play and the Apple App Store. UPDATE: I have recreated Checkmate using Flutter.
