Question

我是团结的新手。我在脚本中看过GUITexture，并且不知道如何使用它。我想知道如何使用GUITexture以及如何在屏幕上显示GUITexture。请帮帮我。

Answer 1

GUI（图形用户界面）纹理，是可以在屏幕上显示的图像，就像在相机上添加图层一样。我的意思是，如果你在屏幕上放置一个GUI纹理，无论玩家去哪里，它总是出现在相对于玩家相机的相同位置。使用GUI纹理的一个很好的例子是，如果你想创建一个始终显示在玩家视角的健康栏。

如何使用GUI纹理：

public class TestGUI {
     //declare a texture, you can do this multiple ways
     public Texture textureType1;
     //this type is usually more blurry because it is being rendered as a texture rather than a plain image
     public 2DTexture textureTyple2;
     //this type is less blurry than Texture, and is used for 2D elements
     public GUITexture textureType3;
     //this type is the clearest and is meant solely for GUI

     public void OnGUI()
     {
          GUI.DrawTexture(new Rect(xOffset, yOffset, width, height), textureType3);
          //This texture is drawn but will not necessarily fill the rectangle you declared
          GUI.DrawTexture(new Rect(xOffset, yOffset, width, height), textureType3, ScaleMode.ScaleToFit, true, 1.0f);
          //this texture is drawn and will be scaled to fill the dimensions of the rectangle you declared with a fill aspect ratio of 1.
          //this is good for things like health bars since it doesnt matter if the image is stretched since it will most likely only be a color
     }
}
