## How to play
|
|
|
|
Tap the unique color block as fast as possible.
|
|
|
|
## Features
|
|
|
|
1. Each round when user taps the unique color block, score will be increased by one.
|
|
2. Timer: 30 seconds countdown.
|
|
3. Color difference will be stepwise reduced when user reached a higher score.
|
|
4. If it is difficult to distinguish the unique color block, user can "SHAKE" the device to shift to another theme color, while the position of the unique color block still keep the same.
|
|
5. Provide a restart button at the end, user can infinitely play again without relaunching the app.
|
|
6. After each replay, game board's theme color will be different from the previous play.
|
|
7. Give user a grade based on the final score:
|
|
|
|
| score range | grade |
|
|
|-------------|-------|
|
|
| 0 - 9 | Fail |
|
|
| 10 - 19 | D |
|
|
| 20 - 29 | C |
|
|
| 30 - 34 | B |
|
|
| 35 - 39 | B+ |
|
|
| 40 - 44 | A |
|
|
| 45 or above | A+ |
|
|
|
|
## Graphics
|
|
|
|
1. I created all graphics used on the app by using Photoshop.
|
|
2. Flutter is great and now I'm able to demonstrate my artwork on the app into practice.
|
|
|
|
## Techniques used
|
|
|
|
1. Use stateful widget to run the timer countdown animation.
|
|
2. Since only 5kb is allowed, the grade is calculated by using math, instead of writing if-else statement.
|
|
3. Use redux to store the game states:
|
|
|
|
| state | description | data type |
|
|
|-------|----------------------------------------------------------|-------------------|
|
|
| score | Store the player score | int |
|
|
| board | Locate the position of unique color block | [[int],[int],...] |
|
|
| count | Count the no. of replay, for switching the theme color | int |
|
|
| page | Current page / game status | int |
|
|
|
|
| page | description |
|
|
|------|----------------------------------------------------------------|
|
|
| -1 | First launch the app, show the welcome screen with instruction |
|
|

|
