【问题描述】:
我目前无法从另一个脚本中获取我的枚举值,这是我处理枚举的脚本
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,它更改了new waitforsecond 之后的枚举值。现在这是我的第二个脚本。
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取绿色值,如果枚举值从GREEN 更改为YELLOW,它无法获取YELLOW 值,而是仍然绿色。
我试过这样做
public TrafficLightHandler tlc = new TrafficLightHandler();
并通过这样做调用我的枚举
if(tlc.Trafficlight = TRAFFIC_LIGHT.GREEN)
但还是一样
有人可以帮我解决这个问题吗?
【问题讨论】:
-
这些脚本是否附加到同一个
gameObject? -
他们是不同的
-
那么你需要先检索那个脚本,比如
otherGameObject.GetComponent<TrafficLightHandler>() -
如果您关心代码质量,也可以使用
switch或else if -
@Johnny 谢谢。抱歉忘记这样做了
