如何从另一个脚本获得枚举值(统一)

Question

我现在很难从另一个脚本中获得枚举的值--这是我的处理枚举的脚本

TrafficLightHandler.cs

public enum TRAFFIC_LIGHT
{
    GREEN,
    YELLOW,
    RED
};


public class TrafficLightHandler : MonoBehaviour {

    public TRAFFIC_LIGHT Trafficlight;


public IEnumerator TrafficLight(){

    while (true) {

        #region Traffic light is green
        //traffic light 1 = green
        Trafficlight = TRAFFIC_LIGHT.GREEN;

        if(Trafficlight == TRAFFIC_LIGHT.GREEN){
            TrafficLightGreenToRed ();
            traffic_light_signal[0].GetComponent<Renderer>().material = materials [0];
            traffic_light_signal[1].GetComponent<Renderer>().material = materials[2];
            //Debug.Log(Trafficlight.ToString());
        }
        #endregion

        yield return new WaitForSeconds (10);

        #region Traffic light is yellow
        Trafficlight = TRAFFIC_LIGHT.YELLOW;

        if(Trafficlight == TRAFFIC_LIGHT.YELLOW){
            TrafficLightYellowTrafficLight1 ();
            traffic_light_signal[0].GetComponent<Renderer>().material = materials[1];
            //Debug.Log(Trafficlight.ToString());
        }
        #endregion

        yield return new WaitForSeconds(3);

        #region Traffic light is red
        Trafficlight = TRAFFIC_LIGHT.RED;
        if(Trafficlight == TRAFFIC_LIGHT.RED){
            TrafficLightRedToGreen ();
            traffic_light_signal[0].GetComponent<Renderer>().material = materials [2];
            traffic_light_signal[1].GetComponent<Renderer>().material = materials[0];
            //Debug.Log(Trafficlight.ToString());
        }
        #endregion

        yield return new WaitForSeconds (10);

        //SWITCH TO SECOND TRAFFIC LIGHT
        #region Traffic light is yellow
        Trafficlight = TRAFFIC_LIGHT.YELLOW;
        if(Trafficlight == TRAFFIC_LIGHT.YELLOW){
            TrafficLightYellowTrafficLight2();
            traffic_light_signal [1].GetComponent<Renderer> ().material = materials [1];
            //Debug.Log(Trafficlight.ToString());
        }
        #endregion

        yield return new WaitForSeconds (3);
    }
  }
}

在上面的脚本中，它在new waitforsecond之后更改枚举值。这是我的第二个剧本。

StopAndGoHandler.cs

TRAFFIC_LIGHT tlh;
private void TrafficLightSignal(){
    Debug.Log (tlh.ToString());
    if(tlh == TRAFFIC_LIGHT.GREEN){
        Debug.Log ("You can go");
    }
    if(tlh == TRAFFIC_LIGHT.RED){
        Debug.Log ("You need to stop");
    }
    if(tlh == TRAFFIC_LIGHT.YELLOW){
        Debug.Log ("Preparation to stop");
    }
}

这个脚本的问题是它只获得绿色的值，如果枚举值从GREEN变为YELLOW，它无法得到YELLOW值，而是仍然是绿色的。

我试过这么做

 public TrafficLightHandler tlc = new TrafficLightHandler();

通过这样做来呼唤我的爱

 if(tlc.Trafficlight = TRAFFIC_LIGHT.GREEN)

但还是一样

有人能帮我解决这个问题吗。

为了能够使用其他脚本，您需要使用GetComponent<TCompoenent>()作为任何其他组件来检索它。

如果两个脚本都附加到同一个gameObject，那么只需使用当前的gameObject

var tlh = gameObject.GetComponent<TrafficLightHandler>();
...
tlh.Trafficlight

否则，如果脚本附加到不同的对象，那么您需要引用该脚本的持有者来进行实际的检索。

public GameObject otherScriptHolder;
var tlh = otherScriptHolder.GetComponent<TrafficLightHandler>();
...
tlh.Trafficlight
