AndEngine 分析之八------Texture

Texture:
A Texture is a 'image' in the memory of the graphics chip. On Android the width and height of a Texture has to be a power of 2. Therefore AndEngine assembles a Texture from a couple of ITextureSources, so the space can be used better.

 

一个Texture是一个'图片'在内存中的图形片段。在操作系统一个质地的宽度和高度有是2的度。因此andengine集成一个Texture从一对itexturesources，所以空间可以被使用更好。

 

当继承自BaseGameActivity的类覆写onLoadResources（）时

 

	public void onLoadResources() {
		this.mFontTexture = new Texture(256, 256, TextureOptions.BILINEAR_PREMULTIPLYALPHA);

		this.mFont = new Font(this.mFontTexture, Typeface.create(Typeface.DEFAULT, Typeface.BOLD), 32, true, Color.BLACK);

		this.mEngine.getTextureManager().loadTexture(this.mFontTexture);
		this.mEngine.getFontManager().loadFont(this.mFont);
	}

 

 

1.构造方法：

 

	/**
	 * @param pWidth must be a power of 2 (i.e. 32, 64, 128, 256, 512, 1024).
	 * @param pHeight must be a power of 2 (i.e. 32, 64, 128, 256, 512, 1024).
	 */
	public Texture(final int pWidth, final int pHeight) {
		this(pWidth, pHeight, TextureOptions.DEFAULT, null);
	}

 

2.engine加载Texture

 

this.mEngine.getTextureManager().loadTexture(this.mFontTexture);
