How to write a backgammon game using uni-app? The following article will share with you a backgammon game written using uni-app. I hope it will be helpful to you!
1. Game renderings
##2. Game Description
Layout: players, board, rules, buttons
- Game: Players place, the computer moves according to the player or itself chess pieces to cut or shape
- Design: The computer uses
- weight to determine which point has the highest score
The game is written using uniapp uview, with some styles , some are global ones defined by myself, and some are built-in in uview, which can be solved by yourself
3. Game code
