python开发五子棋8 #

  1. UI右侧信息显示
  2. 人机大战的主函数整体实现

收获 #

了解五子棋人机交战背后的python原理，通过PyGame实践学会独立建立和更新项目，完成五子棋游戏开发

UI右侧信息显示 #

本小节为设定界面UI右侧信息显示的方法，包括目前交战双方执手，以及战况.

########################################在main主函数前，添加下列函数#################################################
# 设定界面UI右侧信息显示
def _draw_left_info(screen, font, cur_runner, black_win_count, white_win_count):
    _draw_chessman_pos(screen, (SCREEN_HEIGHT + Stone_Radius2, Start_X + Stone_Radius2), BLACK_CHESSMAN.Color)
    _draw_chessman_pos(screen, (SCREEN_HEIGHT + Stone_Radius2, Start_X + Stone_Radius2 * 4), WHITE_CHESSMAN.Color)

    print_text(screen, font, RIGHT_INFO_POS_X, Start_X + 3, '玩家', BLUE_COLOR)
    print_text(screen, font, RIGHT_INFO_POS_X, Start_X + Stone_Radius2 * 3 + 3, '电脑', BLUE_COLOR)

    print_text(screen, font, SCREEN_HEIGHT, SCREEN_HEIGHT - Stone_Radius2 * 8, '战况：', BLUE_COLOR)
    _draw_chessman_pos(screen, (SCREEN_HEIGHT + Stone_Radius2, SCREEN_HEIGHT - int(Stone_Radius2 * 4.5)), BLACK_CHESSMAN.Color)

    print_text(screen, font, RIGHT_INFO_POS_X, SCREEN_HEIGHT - Stone_Radius2 * 3 + 3, f'{white_win_count} 胜', BLUE_COLOR)

    pygame.gfxdraw.filled_circle(screen, pos[0], pos[1], Stone_Radius2, stone_color)

人机大战的主函数整体实现 #

本小节为五子棋主函数的整体实现方法，可参考第四节中五子棋人人大战的主函数的实现方法，不同点在于使用AI类替换了原有对手的部分.

##################################将已有的五子棋人人大战的主函数替换为下列函数###################################
