Public Methods

Method Description
CreateBatchItem ( ) : SpriteBatchItem

Create an instance of SpriteBatchItem if there is none available in the free item queue. Otherwise, a previously allocated SpriteBatchItem is reused.

DrawBatch ( SpriteSortMode sortMode, Effect effect ) : void

Sorts the batch items and then groups batch drawing into maximal allowed batch sets that do not overflow the 16 bit array indices for vertices.

SpriteBatcher ( GraphicsDevice device ) : System.Collections.Generic

Private Methods

Method Description
CompareDepth ( SpriteBatchItem a, SpriteBatchItem b ) : int

Compares the Depth of a against b returning -1 if a is less than b, 0 if equal, and 1 if a is greater than b. The test uses float.CompareTo(float)

CompareReverseDepth ( SpriteBatchItem a, SpriteBatchItem b ) : int

Implements the opposite of CompareDepth, where b is compared against a.

CompareTexture ( SpriteBatchItem a, SpriteBatchItem b ) : int

Comparison of the underlying Texture objects for each given SpriteBatchitem.

EnsureArrayCapacity ( int numBatchItems ) : void

Resize and recreate the missing indices for the index and vertex position color buffers.

FlushVertexArray ( int start, int end, Effect effect, Texture texture ) : void

Sends the triangle list to the graphics device. Here is where the actual drawing starts.
