A simple sudoku game made with ReactJS.

🚀 deploy

🚀 demo video

Getting Started (Before class)

1. Go to Github.com

2. Press "New Repository" to create a new repository

3. Set the project to Private and name it as 109-1-Web-Hackathon02. DO NOT select a template

4. Make sure the repository is empty:

5. Clone the empty repository into your computer

   • Open your terminal, run git clone https://github.com/<Your Username>/109-1-Web-Hackathon02.git

6. Download package.json, and put it into your directory you just cloned (109-1-Web-Hackathon02/package.json)

7. Install dependencies

   • Open your terminal, run cd 109-1-Web-Hackathon02
   • Run npm install

8. Remove the package.json and package-lock.json files

9. Go to "Settings" > "Manage access" > "Invite collaborators"

10. Add ntuee-webprogramming as a collaborator

This step is REALLY IMPORTANT. It is the only way we can grade your work

Getting Started (In Class)

11. Import code from template:

12. Import Template from https://github.com/ntuee-webprogramming/109-1-Web-Hackathon02

    

13. Open terminal, run cd 109-1-Web-Hackathon02/

14. Run git pull

15. Run npm start

16. That's it! happy hacking! 😃

Files Structure of the project

• The file structure is as follw:

  

• We store the grid values in a 2D array: where the "0"s representing empty grids

Requirements

1. Implement Grid_1x1.js using either react component or react hook (50% in total)

   • First, make sure you could load the game correctly (30%)

     • This File Grid_1x1.js is empty now and you will get errors if you try to load the game
     • You could decide to implement this file with either react component or react hook
     • Hint. Make sure you have the following code in your Grid_1x1.js if you are using react component:

     const gridStyle = {
         color: (this.props.selectedGrid.row_index === this.props.row_index && this.props.selectedGrid.col_index === this.props.col_index) || this.props.conflicted ? "#FFF" : this.props.fixed ? "#666" : "#6CC",
         backgroundColor: this.props.selectedGrid.row_index === this.props.row_index && this.props.selectedGrid.col_index === this.props.col_index ? "#333" : this.props.conflicted ? "#E77" : "#FFF",
     };
     return (
         <div className="grid_1x1" id={`grid-${this.props.row_index}*${this.props.col_index}`} tabindex="1" style={gridStyle} onClick={() => this.props.handle_grid_1x1_click(this.props.row_index, this.props.col_index)}>
             { this.props.value === "0" ? "" : this.props.value}
         </div>
     );
     

     or this if you are using react hook:

     const gridStyle = {
         color: (props.selectedGrid.row_index === props.row_index && props.selectedGrid.col_index === props.col_index) || props.conflicted ? "#FFF" : props.fixed ? "#666" : "#6CC",
         backgroundColor: props.selectedGrid.row_index === props.row_index && props.selectedGrid.col_index === props.col_index ? "#333" : props.conflicted ? "#E77" : "#FFF",
     };
     return (
         <div className="grid_1x1" id={`grid-${props.row_index}*${props.col_index}`} tabindex="1" style={gridStyle} onClick={() => props.handle_grid_1x1_click(props.row_index, props.col_index)}>
             { props.value === "0" ? "" : props.value}
         </div>
     );
     

     Some properties given to the div are really important, make sure you don't miss any of them

     • To see the following figure: If the Grid_1x1.js works, you should be able to load the values of the game by selecting the menu (Select test01.json to check)

   • Further, You should apply proper style on different Grid_1x1s depending on their positions (10%)

     • The borders of each Grid_1x1 are different:

     • Hint. The position is given by the props.row_index and props.col_index

     • You could refer to Grid_9x9.js for some information

   • Finally, make the empty grid selectable (10%)

     • When a grid_1x1 get clicked, its style should contain

     backgroundColor: "#333", color: "#FFF"
     

     

     • Hint. You should completed the function "handle_grid_1x1_click" in Sudoku.js, which should set the state properly:

     selectedGrid: { row_index: -1, col_index: -1}
     

2. Implement input functions (30% in total)

   • Firstly, complete the key board inupt function (20%)
     • When user press the key (0~9), the currently selected grid should be update.
     • Hint. You should complete hadleKeyDownEvent function in Sudoku.js. (Given keyboard event, update gridValues in state correspondingly)
     • Notice. There are different keyCodes for number 0-9 (48-57 and 96-105). Make sure you handle them all.
   • Secondarily, complete the screen keyboard input function (10%)
     • Hint. You should complete hadleScreenKeyboardInput function in Sudoku.js. (Given input number (0~9, Integer), update gridValues in state correspondingly)

3. Check If the input is valid (20% in total)

   • When user input a number (with keyboard or screen keyboard), you should avoid the input if the input is not valid (20%) see 數獨規則 for more information

Bonus

1. Highlight conflicts grids (5%)

   • When an invalid input is given, you should highlight the other conflicts grids for one secend
   • Hint. You should set the conflicts in state properly

2. Add error effect to the game board boarder (3%)

   • When an invalid input is given, you should make the border style of the gameboard (id="game-board") to "8px solid #E77" for 1 second
   • Hint. You may use the following code:

     this.setState({ gameBoardBorderStyle: "8px solid #E77" });
     setTimeout(() => { this.setState({ gameBordBoarderStyle: "8px solid #333" }); }, 1000);
     

3. Set off Firework effect when the user win (2%)

   • Hint. You may use the following code:

     this.setState({ completeFlag: true });
     setTimeout(() => { this.setState({ completeFlag: false }); }, 2500);
     

Challenge

1. Implement the AUTOCOMPLETE function
2. Implement RESET GAME function

Running Tests

1. In your terminal, run npm start and make sure you are running your app using localhost:3000
2. Open another terminal, run npm run test
3. If error like npx command not found come out, please runnpm install -g npx first
4. If everything goes well, you will see the following output:

Push your code to Github

1. Run git add .
2. Run git commit -m "test"
3. Run git push
