OnMouseOver在Unity中

Question

快速問題我在這裏得到了這個腳本來顯示你收集的物品的名稱。這些名稱是公開的，所以我可以在項目列表中更改它們。我想要做的是走進一個項目並將鼠標懸停在項目上，以便它可以在屏幕中間顯示項目的名稱。我不知道我是否應該使用觸發器，或者GUILayout或其他。請幫助和謝謝。下面是腳本：修訂

public class RayCasting : MonoBehaviour 
{ 
public float pickupDistance; 
public List<Item> items; 
//public List<Keybutton> buttons; 

#region Unity 
void Start() 
{ 
    Screen.lockCursor = false; 

    for (int i = 0; i < items.Count; i++) { 
     Item temp = items[i]; 
     int randomIndex = Random.Range(i, items.Count); 
     items[i] = items[randomIndex]; 
     items[randomIndex] = temp; 
    } 
} 
void Update() 
{ 
      RaycastHit hit; 
      Ray ray = new Ray (transform.position, transform.forward); 
      if (Physics.Raycast (ray, out hit, pickupDistance)) { 
        foreach (Item item in items) { 

          if (Input.GetMouseButtonDown (0)) { 
            if (item.gameObject.Equals (hit.collider.gameObject)) { 
              numItemsCollected++; 
              item.Collect(); 
              break; 
            } 

          } 
        } 
      } 
    } 

void OnGUI() 
{ 

    GUI.backgroundColor = Color.blue; 
    GUI.Box(new Rect(120,390,170,250),"Text Message"); 
    GUILayout.BeginArea(new Rect(132,432,100,170)); 
    { 
     GUILayout.BeginVertical(); 
     { 
    if (numItemsCollected < items.Count) 
    { 
     foreach (Item item in items) 

        GUILayout.Label(string.Format("[{0}] {1}", item.Collected ? "" + item.password: " ", item.name)); 

    } 
    else 
    { 
    foreach (Item item in items) 

        GUILayout.Label(string.Format("[{0}] {1}", item.Collected ? "" + item.password: " ", item.name));   
       //GUILayout.Label("Take code to KeyPad"); 
    } 
     } 
     GUILayout.EndVertical(); 
} 
    GUILayout.EndArea(); 

    //Enter Code to unlock doors. 

        if (GUI.Button (new Rect (250, 830, 100, 50), "Enter Code")) 
        if (numItemsCollected > items.Count) {    
          Debug.Log ("Entering Code"); 
       } 
} 

#endregion 

#region Private 
private int numItemsCollected; 
#endregion 
}

public class Item 
{ 
public string name; 
//public GUIText textObject; 
public GameObject gameObject; 
public float guiDelay = 0.1f; 

private float lastHoverTime = -99.0f; 
public int password; 

public bool Collected { get; private set; } 



public void Collect()

    Collected = true; 
    //gameObject.SetActive(false); 
} 

public void passwordNumber() 
{ 
    password = 0; 
    Collected = true; 
    gameObject.SetActive(false);

void OnMouseEnter()

    lastHoverTime = Time.timeSinceLevelLoad; 
} 

void OnGUI(){ 
      if (lastHoverTime + guiDelay > Time.timeSinceLevelLoad) { 
        GUI.Box (new Rect (300, 300, 170, 250), name); 
      } 
    } 
}

安裝下面的腳本到每個項目。鼠標懸停該項目時，它將顯示QUI.Box。只需更改QUI.Box的大小並將message設置爲合適的值即可。

using UnityEngine; 
using System.Collections; 

public class HoverGUI : MonoBehaviour { 

    public string message = "Foo Bar"; 
    public float guiDelay = 0.1f; 

    private float lastHoverTime = -99.0f; 
    void OnMouseOver() { 
     lastHoverTime = Time.timeSinceLevelLoad; 
    } 

    void OnGUI(){ 
     if(lastHoverTime + guiDelay > Time.timeSinceLevelLoad){ 
      GUI.Box(new Rect(0,0,170,250),message); 
     } 
    } 
}
