示例1: onUpdateVertices

import org.andengine.entity.primitive.Gradient; //导入依赖的package包/类
@Override
public void onUpdateVertices(final Gradient pGradient) {
	final float[] bufferData = this.mBufferData;

	final float width = pGradient.getWidth(); // TODO Optimize with field access?
	final float height = pGradient.getHeight(); // TODO Optimize with field access?

	bufferData[(0 * Gradient.VERTEX_SIZE) + Gradient.VERTEX_INDEX_X] = 0;
	bufferData[(0 * Gradient.VERTEX_SIZE) + Gradient.VERTEX_INDEX_Y] = 0;

	bufferData[(1 * Gradient.VERTEX_SIZE) + Gradient.VERTEX_INDEX_X] = 0;
	bufferData[(1 * Gradient.VERTEX_SIZE) + Gradient.VERTEX_INDEX_Y] = height;

	bufferData[(2 * Gradient.VERTEX_SIZE) + Gradient.VERTEX_INDEX_X] = width;
