用c#与数据库做一个文字小游戏（一）

计划

人物系统（人物表）
{
人物升级，人物属性
}
怪物系统（怪物表）
{
怪物名字，属性，掉落的东西
}
背包系统
{
物品名，物品数量。
}

装备系统
{
装备属性
}

宠物系统

第一个系统，人物系统准备。

人物必然需要升级与攻击力，用数据库后触发器，当经验值满足一定条件时，等级与攻击力增加

//修改后的

ALTER  TRIGGER [dbo].[trigger_update] 
on   [dbo].[PERSON]
after update
as 
declare  @a int ;
declare  @b int ;

 set @a = (select  empirical from [dbo].[PERSON] )
 set @b=  (select  Grade from [dbo].[PERSON] ) 
if  (@a > = (@b*10))
begin 
update [dbo].[PERSON]
set  Grade=Grade+1,Empirical=0
WHERE  Grade=(SELECT Grade FROM deleted)and Empirical=(SELECT Empirical FROM deleted)
END

ALTER  TRIGGER [dbo].[trigger_update1] 
on   [dbo].[PERSON]
after update
as 
if  update (grade)
begin 
update [dbo].[PERSON]
set  wuli=wuli+1
WHERE  wuli=(SELECT wuli FROM deleted)
END

为了方便对战等操作把人物与怪物的函数分别写入person monster类中

PERSON类
