position | 要在其中绘制纹理的屏幕矩形。 |
image | 要显示的 Texture。 |
texCoords | 当图像的宽高比不适合要绘制的宽高比时,如何缩放图像。 |
alphaBlend | 是否将图像 Alpha 混合到显示屏上(默认值)。如果为 false,则将图片绘制到显示屏上。 |
使用给定的纹理坐标在矩形内绘制纹理。
使用该函数在给定矩形内裁剪或平铺图像。第二个 Rect texCoords
描述如何调整纹理以适应位置 Rect。第一个矩形的大小以像素为单位;第二个矩形的范围为 0.0 到 1.0。\

using UnityEngine;
// Use DrawTextureWithTexCoords() to draw a texture. The texture is draw on the window // inside a given pixel rectangle. The size of the drawn texture is based on the value // of hor. This ranges from 0.5 to 1.25 so the bottom left half of the texture to a // greater than normal value.
