如何从一个链接

Question

• 我有我已经宣布在画布

• 到该图像，我需要从一个链接加载图像（“图像的场景HTTP负载在Unity的图像/资产/屏幕保护程序“）

其实我也做了一些加载图像：

urllll = "http://192.168.137.129/ooredoo/client_api/" + ConfirmPath; 
WWW imgLink1 = new WWW (urllll); 
img1 = imgLink1.texture; 

• 但这种负荷的形象，整个场面完全
• 我需要装载我在画布上已经宣布在图像上的图像

Answer 1

你正在下载纹理并将其存储在img1变量中，该变量是Texture2D的一种类型。随后在OnGUI函数中使用GUILayout.Label显示Texture2D图像。问题是重新调整图像...

就像我在您的other发表的帖子中提到的那样，不是使用OnGUI函数。做不是使用任何Unity API，需要OnGUI函数除非你正在编辑插件。

在你的函数，

void OnGUI() 
{ 
    foreach (UnityEngine.Touch touch in Input.touches) 
    { 
     guitextureindi = false; 
    } 

    if (guitextureindi) 
    { 
     GUILayout.Label (img1); 
    } 
} 

传递的width和length要的GUILayout.Label功能。

例如：

public float textureWidth = 400; 
public float textureHeight = 400; 

public Texture2D img1; 
void OnGUI() 
{ 
    GUILayout.Label(img1, GUILayout.Width(textureWidth), GUILayout.Height(textureHeight)); 
} 

在Unity显示图像的正确/正确的方法：

随着Image组件：

public float textureWidth = 400; 
public float textureHeight = 400; 

public Texture2D img1; 
public Image textureDisplayer; 

void SomeFunction() 
{ 
    textureDisplayer.sprite = Sprite.Create(img1, new Rect(0, 0, textureWidth, textureHeight), new Vector2()); 
} 

随着RawImage组件：

public int textureWidth = 400; 
public int textureHeight = 400; 

public Texture2D img1; 
public RawImage textureDisplayer; 

void SomeFunction() 
{ 
    img1.Resize(textureWidth, textureHeight); 
    textureDisplayer.texture = img1; 
} 

您也可以调整Image或RawImage在屏幕上：

textureDisplayer.GetComponent<RectTransform>().sizeDelta = new Vector2(textureWidth, textureHeight); 

简单的下载，调整大小和显示图像样本：

public int textureWidth = 400; 
public int textureHeight = 400; 

public RawImage textureDisplayer; 

void Start() 
{ 
    string imageUrl = "http://images.earthcam.com/ec_metros/ourcams/fridays.jpg"; 
    StartCoroutine(LoadImg(imageUrl)); 
} 

void displayImage(Texture2D imgToDisp) 
{ 
    //Resize Image 
    textureDisplayer.GetComponent<RectTransform>().sizeDelta = new Vector2(textureWidth, textureHeight); 
    textureDisplayer.texture = imgToDisp; 
} 


IEnumerator LoadImg(string url) 
{ 
    yield return null; 
    WWW www = new WWW(url); 
    yield return www; 

    displayImage(www.texture); 
}
