Parameters 参数

screenRect	Rectangle on the screen to use for the texture. In pixel coordinates with (0,0) in the upper-left corner.
texture	Texture to draw.
sourceRect	Region of the texture to use. In normalized coordinates with (0,0) in the bottom-left corner.
leftBorder	Number of pixels from the left that are not affected by scale.
rightBorder	Number of pixels from the right that are not affected by scale.
topBorder	Number of pixels from the top that are not affected by scale.
bottomBorder	Number of pixels from the bottom that are not affected by scale.
color	Color that modulates the output. The neutral value is (0.5, 0.5, 0.5, 0.5). Set as vertex color for the shader.
mat	Custom Material that can be used to draw the texture. If null is passed, a default material with the Internal-GUITexture.shader is used.

Description 描述

Draw a texture in screen coordinates.

在屏幕坐标上绘制一个纹理。

If you want to draw a texture from inside of OnGUI code, you should only do that from EventType.Repaint events. It's probably better to use GUI.DrawTexture for GUI code.

如果你想从OnGUI代码里面绘制纹理，你仅需要从EventType.Repaint事件绘制。它可能比使用GUI.DrawTexture更好。

JavaScript:

	// Draws a texture on the screen at 10, 10 with 100 width, 100 height.
 
	var aTexture : Texture;
 
	function OnGUI() {
		if(Event.current.type.Equals(EventType.Repaint))
			Graphics.DrawTexture(Rect(10, 10, 100, 100), aTexture);
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public Texture aTexture;
    void OnGUI() {
        if (Event.current.type.Equals(EventType.Repaint))
            Graphics.DrawTexture(new Rect(10, 10, 100, 100), aTexture);
 
    }
}
