use of com.esotericsoftware.spine.utils.TwoColorPolygonBatch in project talos by rockbite.

the class BVBSkeletonRenderer method draw.

/**
 * Renders the specified skeleton. If the batch is a PolygonSpriteBatch, {@link #draw(SpriteBatchParticleRenderer, PolygonSpriteBatch, SkeletonContainer, Skeleton)} is
 * called. If the batch is a TwoColorPolygonBatch, {@link #draw(SpriteBatchParticleRenderer, TwoColorPolygonBatch, SkeletonContainer, Skeleton)} is called. Otherwise the
 * skeleton is rendered without two color tinting and any mesh attachments will throw an exception.
 * <p>
 * This method may change the batch's {@link Batch#setBlendFunctionSeparate(int, int, int, int) blending function}. The
 * previous blend function is not restored, since that could result in unnecessary flushes, depending on what is rendered
 * next.
