检测到触发时添加UI文本

Question

如何在检测到触发时添加UI文本？ 我有这段代码来检测玩家是否在触发器中，但是如果玩家进出触发器，我希望在画布上出现一个消息“Map on”/“Map off”。谢谢！

public class MapDetect : MonoBehaviour { 

private bool isTriggered; 

void OnTriggerEnter(Collider other) 
{ 
    if (other.gameObject.CompareTag("Player")) 
     isTriggered = true; 
} 

void OnTriggerExit(Collider other) 
{ 
    if (other.gameObject.CompareTag("Player")) 
     isTriggered = false; 
} 

void Update(){ 
    if(Input.GetKey(KeyCode.Space)){ 
     Debug.Log(isTriggered); 
    } 
} 
} 

更新代码：

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine; 
using UnityEngine.UI; 

public class DetectarMapa : MonoBehaviour { 

public GameObject T1; 
public GameObject T2; 

public float time = 3; 

void Start() 
{ 
    T1.SetActive (true); 
    StartCoroutine(Message1()); 
} 

void OnTriggerEnter(Collider other) 
{ 
    if (other.gameObject.CompareTag("Player")) 
     T2.SetActive (true); 
     StartCoroutine(Message2()); 
} 

void OnTriggerExit(Collider other) 
{ 
    if (other.gameObject.CompareTag("Player")) 
     T1.SetActive (true); 
     StartCoroutine(Message1()); 
} 

IEnumerator Message1() 
{ 
    yield return new WaitForSeconds(time); 
    T1.SetActive (false); 
} 

IEnumerator Message2() 
{ 
    yield return new WaitForSeconds(time); 
    T2.SetActive (false); 
} 
}

只是一个引用添加到您的Text组件并在需要时设置text属性：

public class MapDetect : MonoBehaviour { 

    public Text Text; 

    void Start() 
    { 
     Text.text = "Map out"; 
    } 

    void OnTriggerEnter(Collider other) 
    { 
     if (other.gameObject.CompareTag("Player")) 
      Text.text = "Map on"; 
    } 

    void OnTriggerExit(Collider other) 
    { 
     if (other.gameObject.CompareTag("Player")) 
      Text.text = "Map out"; 
    } 
} 

在Unity

然后简单的引用添加到文本组件。
