1.功能描述
几乎所有的RPG游戏在进入游戏时都会让用户自己来创建自己喜欢的角色。本次上机要求编写一个简化的创建游戏角色的程序。
2.游戏角色应有的属性
本题目要求的游戏角色应有以下属性:名字、性别、种族、职业、力量、敏捷、体力、智力、智慧、生命值和魔法值。
名字:不超过50个字符。
性别:可以选择男性和女性。
种族:一共可选五个种族,人类、精灵、兽人、矮人和元素。
职业:可选六种职业,狂战士、圣骑士、刺客、猎手、祭司和巫师。
其余属性均为整数。
本题目要求首先用户输入角色姓名,然后由用户选择角色性别,然后由用户选择种族,然后选择职业,然后自动分配力量、敏捷、体力、智力和智慧属性,并计算生命值和魔法值。
生命值=体力*20。
魔法值=(智力+智慧)*10。
3.职业限制
很多职业会限制某些种族选择,例如兽人不能就职圣骑士等等,种族和职业的限制表如下:
种族/职业 |
狂战士 |
圣骑士 |
刺客 |
猎手 |
祭司 |
巫师 |
人类 |

所以在要求用户选择职业时,输出信息里面只能有用户所选择种族可以就职的职业。
4.初始属性
本题目要求力量、敏捷、体力、智力和智慧要求是随机值(利用随机数函数来取得随机数),但是五项属性的总和应该是100,并且应该和职业相关。例如狂战士的体力和力量就要比较高,而巫师需要较高的智力,而祭司则需要较高的智慧。各职业初始属性的大致比例应遵从下表:
职业/属性 |
力量 |
敏捷 |
体力 |
智力 |
智慧 |
狂战士 |
40 |
20 |
30 |
5 |
5 |
圣骑士 |
25 |
15 |
30 |
20 |
10 |
刺客 |
20 |
35 |
20 |
15 |
10 |
猎手 |
15 |
40 |
15 |
10 |
20 |
祭司 |
15 |
20 |
15 |
35 |
15 |
巫师 |
10 |
20 |
10 |
20 |
40 |
例如,前面示意图中的祭司的初始属性,大致满足该比例,但是应该是随机的。
然后利用属性值计算生命值和魔法值。
5.显示信息
最后向用户显示该角色的所有信息,然后询问用户是否满意,如用户不满意则重新创建,若用户满意则程序结束,并将用户创建角色的相关信息写入文件保存。
6.主要代码:
