파라미터

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.
pass If -1 (default), draws all passes in the material. Otherwise, draws given pass only.

설명

Draw a texture in screen coordinates.

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.

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); } }
