Unity常用命令模式详解

三、配制加载器

public class RemoteLoader : MonoBehaviour
{
  public Button lastBtn;
  public Button nextBtn;

  private int index;
  private const int NUM_COMMAND = 10;
  private ICommand[] commands;
  private string[] textinfos;

  private MoveCommand movexCmd;
  private MoveCommand moveyCmd;
  private MoveCommand movezCmd;
  private RotateCommand rotxCmd;
  private RotateCommand rotyCmd;
  private RotateCommand rotzCmd;
  private ColorChangeCommand redColorCmd;
  private ColorChangeCommand greenColorCmd;
  private ColorChangeCommand blueColorCmd;
  private TextChangeCommand textCmd;

  private string[] infos = { "A","B", "C", "D", "E", "F" };
  public RemoteControl remoteCtrl;

  public GameObject cube;

  void Awake()
  {
    lastBtn.onClick.AddListener(OnLastBtnClicked);
    nextBtn.onClick.AddListener(OnNextBtnClicked);
  }

  void Start()
  {
    commands = new ICommand[NUM_COMMAND];
    textinfos = new string[NUM_COMMAND];

    textinfos[0] = "x方向移动";
    commands[0] = new MoveCommand(cube.transform, Vector3.right);
    textinfos[1] = "y方向移动";
    commands[1] = new MoveCommand(cube.transform, Vector3.up);
    textinfos[2] = "z方向移动";
    commands[2] = new MoveCommand(cube.transform, Vector3.forward);

    textinfos[3] = "x轴旋转10度";
    commands[3] = new RotateCommand(cube.transform, Vector3.right * 10);
    textinfos[4] = "y轴旋转10度";
    commands[4] = new RotateCommand(cube.transform, Vector3.up * 10);
    textinfos[5] = "z轴旋转10度";
    commands[5] = new RotateCommand(cube.transform, Vector3.forward * 10);

    textinfos[6] = "变红";
    commands[6] = new ColorChangeCommand(Color.red, cube.GetComponent<Renderer>().material);
    textinfos[7] = "变绿";
    commands[7] = new ColorChangeCommand(Color.green, cube.GetComponent<Renderer>().material);
    textinfos[8] = "变蓝";
    commands[8] = new ColorChangeCommand(Color.blue, cube.GetComponent<Renderer>().material);
    textinfos[9] = "换信息";
    commands[9] = new TextChangeCommand(cube.GetComponentInChildren<TextMesh>(), infos);
  }

  private void OnNextBtnClicked()
  {
    if (index == NUM_COMMAND || index == -1)
    {
      index = 0;
    }

    remoteCtrl.SetCommond(commands[index]);
    remoteCtrl.SetText(textinfos[index]);
    index++;
  }

  private void OnLastBtnClicked()
  {
    if (index == NUM_COMMAND || index == -1)
    {
      index = NUM_COMMAND - 1;
    }

    remoteCtrl.SetCommond(commands[index]);
    remoteCtrl.SetText(textinfos[index]);
    index--;
  }

}
