嗯.. SVN上上传PlayerState.cbp
该工程实现 State 设计模式
具体如下...
1 //forward decl
2 class PlayerState;
3
4 class Player
5 {
6 public:
7 Player(PlayerState* initState);
8
9 void walk();
10 void stand();
11 void jump();
12
13 void setState(PlayerState* state);
14 protected:
15 PlayerState* mState;
16
17 //decl uncopyable
18 Player(const Player& player);
19 Player& operator=(const Player& rhs);
20 };
21
玩家的行为转由状态对象处理
//forward decl
class Player;
class PlayerState
{
public:
virtual void walk(Player* player) = 0;
virtual void stand(Player* player) = 0;
virtual void jump(Player* player) = 0;
};
class Walking : public PlayerState
{
public:
void walk(Player* player);
void stand(Player* player);
void jump(Player* player);
static Walking* getInstancePtr();
protected:
//singleton
Walking();
static Walking* mInstance;
};
class Standing : public PlayerState
{
public:
void walk(Player* player);
void stand(Player* player);
void jump(Player* player);
static Standing* getInstancePtr();
protected:
Standing();
static Standing* mInstance;
};
class Jumping : public PlayerState
{
public:
void walk(Player* player);
void stand(Player* player);
void jump(Player* player);
static Jumping* getInstancePtr();
protected:
Jumping();
static Jumping* mInstance;
};
相对比较简单... 可以当一个非常无聊的文字MUD来玩..
