統一的透明3d

Question

我希望我的問題不重複; 我有一個統一的問題。 我寫了一個透明的類（淡入/淡出循環）的對象。這是正確的。 我在場景中放了兩個按鈕，他們在畫布的地方。 運行後，儘管我已經爲畫布中的透明對象寫了一個命令，但裏面的所有內容都變爲透明（淡入和淡出循環）。 我不知道。 請幫忙。

MyClass的

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

public class Transparent : MonoBehaviour { 

private float duration = .7f; 
    public float waitTime; 
    IEnumerator co2; 
    // Update is called once per frame void 
    public void start_tranparecncy() 
    { 
     this.co2=this.blink(); 
     this.StartCoroutine (this.co2); 
    } 
    IEnumerator blink() { 

     //Color textureColor = this.transform.GetComponent<SpriteRenderer>().material.color; 
     Color textureColor = this.transform.GetComponent<Image>().material.color; 

     //textureColor.a = Mathf.PingPong(Time.time, duration)/duration; 
     //this.GetComponent<SpriteRenderer>().material.color = textureColor; 
     while (true) { // this could also be a condition indicating "alive or dead" 
      // we scale all axis, so they will have the same value, 
      // so we can work with a float instead of comparing vectors 
      textureColor.a=Mathf.PingPong (Time.time, duration)/duration; 
      this.transform.transform.GetComponent<Image>().material.color = textureColor; 

      // reset the timer 

      yield return new WaitForSeconds (waitTime); 



     } 
     //end of if(this.transform.childCount =0) 

    } 

    void stop_Transparency() 
    { 

     this.StopCoroutine (this.co2); 

    } 
}

好吧，我發現你的問題是主要的

this.transform.transform.GetComponent<Image>(); 

因爲雙變換，我t達到一個上層的父母，這是你的畫布本身。所以你畫布上的所有東西都會失去alpha值。

還編輯了一下你的代碼。而不是使用材質顏色，直接更改了圖像組件的Alpha顏色值。

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

public class Transparent : MonoBehaviour 
{ 
    private float duration = .7f; 
    public float waitTime; 
    IEnumerator co2; 

    public void start_tranparecncy() 
    { 
     this.co2 = this.blink(); 
     this.StartCoroutine(this.co2); 
    } 

    IEnumerator blink() 
    { 
     //Color textureColor = this.transform.GetComponent<SpriteRenderer>().material.color; 
     Color textureColor = this.transform.GetComponent<Image>().color; 

     //textureColor.a = Mathf.PingPong(Time.time, duration)/duration; 
     //this.GetComponent<SpriteRenderer>().material.color = textureColor; 

     while (true) 
     { // this could also be a condition indicating "alive or dead" 
      // we scale all axis, so they will have the same value, 
      // so we can work with a float instead of comparing vectors 
      textureColor.a = Mathf.PingPong(Time.time, duration)/duration; 
      this.transform.GetComponent<Image>().color = textureColor; 

      // reset the timer 

      yield return new WaitForSeconds(waitTime); 
     } 
     //end of if(this.transform.childCount =0) 

    } 

    void stop_Transparency() 
    { 
     this.StopCoroutine(this.co2); 
    } 
} 

我已將此腳本附加到畫布中的按鈕。還可以在同一按鈕的On Click()中運行start_tranparecncy()功能。

按下按鈕後，只有按鈕的alpha值正在改變。

如果您願意，您可以更改On Click()並添加另一個按鈕。
