求一个RMVX的时间系统？ - Project1

# rmvx时钟 by 沉影不器
#------------------------------------------------------------------------------
# 功能描述: 显示一个带指针的时钟
# 素材准备: 时钟指针分别命名为 hour_hand、minute_hand、second_hand
# 时钟背景命名为 clock_bg,另需要一个盖住指针的圆扣命名为 top_button
# 使用方法: Main之前插入脚本,在需要时钟的场景中调用:
# Sprite_Clock.new(x坐标, y坐标, 不透明度)
# (参考范例Scene_Map添加时钟)
# 脚本第18行设定控制时钟显示的变量号
