《消亡的海》游戏开发日志02-移动

一切都是摸着石头过河，因为只有一个人在开发，且也不想事先策划。
计划先写一些简单的，后面再添加。

今天先完成：

①建个城市;
②生成个角色;
③角色在城市里移动

城市 类

public class City {

    public string cityName;
    public int cityId;
    public int width; // 城市格子数
    public int height;

    // Npc列表 城内的NPC们
    public List<Npc> npcList;

    // Room列表 城内有哪些房间
    public List<Room> roomList;
}

public class Pos {

    public int xPos;
    public int yPos;
}

角色 类

public class Role {

    public string uname;
    public Pos pos; // 角色在城内的坐标
    public float xStep; // 在格子内的像素位置
    public float yStep;

    // 状态
    public bool isAllowMove;
    public string faceTo;

    // 交互的NPC
    public Npc talkNpc;

    public Role(string _uname, Pos _pos) {

        uname = _uname;

        pos = _pos;

        xStep = 0;

        yStep = 0;

        // 状态
        isAllowMove = true;

        faceTo = "down";

        // 交互
        talkNpc = null;

    }

    public void Move(string _dir, City _city) {

        if (_dir == "up") {

            // 超过一格
            if (yStep + 1 >= RoleConfig.gridStep) {

                // 超出城市上界
                if (pos.yPos + 1 < _city.height) {

                    yStep = 0;

                    pos.yPos += 1;

                }

            // 未超一格
            } else {

                yStep += 1;

            }

            faceTo = "up";

        } else if (_dir == "down") {

            // 超过一格
            if (yStep - 1 < 0) {

                // 超出城市下界
                if (pos.yPos - 1 >= 0) {

                    yStep = RoleConfig.gridStep;

                    pos.yPos -= 1;

                }

            // 未超一格
            } else {

                yStep -= 1;

            }

            faceTo = "down";

        } else if (_dir == "left") {

            if (xStep - 1 < 0) {

                // 超出城市左界
                if (pos.xPos - 1 >= 0) {

                    xStep = RoleConfig.gridStep;

                    pos.xPos -= 1;

                }

            } else {

                xStep -= 1;

            }

            faceTo = "left";

        } else if (_dir == "right") {

            if (xStep + 1 >= RoleConfig.gridStep) {

                // 超出城市右界
                if (pos.xPos + 1 < _city.width) {

                    xStep = 0;

                    pos.xPos += 1;

                }

            } else {

                xStep += 1;

            }

            faceTo = "right";

        }
    }
}

游戏数据 类

public class GameData {

    static GameData instance;
    public static GameData Instance {

        get {

            if (instance == null) {

                instance = new GameData();

            }

            return instance;

        }
    }
    public City city;
    public Role role;

    public void CreateGame() {

        city = new City("出生城", 0, 10, 10);

        role = new Role("白沙", new Pos(2, 3));

    }
}

Unity的操作控制类

public class ControlManager : MonoBehaviour {

    public static ControlManager Instance;

    void Awake() {

        if (Instance == null) Instance = this;

    }

    void Update() {

        Move();

    }

    void Move() {

        Role role = App.Instance.role;

        if (role == null) return;

        if (role.isAllowMove == false) return;

        bool _up = Input.GetKey(KeyCode.W);

        bool _down = Input.GetKey(KeyCode.S);

        bool _left = Input.GetKey(KeyCode.A);

        bool _right = Input.GetKey(KeyCode.D);

        if(_up) {

            role.Move("up", App.Instance.city);

        }

        if (_down) {

            role.Move("down", App.Instance.city);

        }

        if (_left) {

            role.Move("left", App.Instance.city);

        }

        if (_right) {

            role.Move("right", App.Instance.city);

        }

    }
}

数据测试 类

public class TestManager : MonoBehaviour {

    public static TestManager Instance;

    public Text roleText;
    public Text cityText;
    public Text npcText;

    void Awake() {

        if (Instance == null) Instance = this;

    }

    void Start() {

    }

    void Update() {

        ShowText();

    }

    void ShowText() {

        ShowRole();

        ShowCity();

    }

    void ShowRole() {

        Role role = App.Instance.role;

        if (role == null) return;

        roleText.text = 
            "角色名：" + role.uname +
            "\n步标：" + role.xStep.ToString() + "," + role.yStep.ToString() +
            "\n坐标：" + role.pos.xPos.ToString() + "," + role.pos.yPos.ToString();

        if (role.talkNpc == null) return;

        roleText.text += 
            "\n当前互动NPC：" + role.talkNpc.nname;

    }

    void ShowCity() {

        City city = App.Instance.city;

        if (city == null) return;

        cityText.text = 
            "城市名：" + city.cityName +
            "\n城市宽高：" + city.width.ToString() + "," + city.height.ToString();

        npcText.text = "";

        foreach (Npc _npc in city.npcList) {

            npcText.text += 
                "\n \nNPC名：" + _npc.nname +
                "\n坐标：" + _npc.pos.xPos.ToString() + "," + _npc.pos.yPos.ToString();
        }

    }
}

现在看看角色移动效果

按WSAD走走看，嗯，角色动起来了。（动图太大就只放一小段）
