PolygonSpriteBatch (gdx 1.11.0 API)

java.lang.Object
- com.badlogic.gdx.graphics.g2d.PolygonSpriteBatch

All Implemented Interfaces:

Batch, PolygonBatch, Disposable
```
public class PolygonSpriteBatch
extends java.lang.Object
implements PolygonBatch
```
A PolygonSpriteBatch is used to draw 2D polygons that reference a texture (region). The class will batch the drawing commands and optimize them for processing by the GPU.
To draw something with a PolygonSpriteBatch one has to first call the begin() method which will setup appropriate render states. When you are done with drawing you have to call end() which will actually draw the things you specified.
All drawing commands of the PolygonSpriteBatch operate in screen coordinates. The screen coordinate system has an x-axis pointing to the right, an y-axis pointing upwards and the origin is in the lower left corner of the screen. You can also provide your own transformation and projection matrices if you so wish.
A PolygonSpriteBatch is managed. In case the OpenGL context is lost all OpenGL resources a PolygonSpriteBatch uses internally get invalidated. A context is lost when a user switches to another application or receives an incoming call on Android. A SpritPolygonSpriteBatcheBatch will be automatically reloaded after the OpenGL context is restored.
A PolygonSpriteBatch is a pretty heavy object so you should only ever have one in your program.
A PolygonSpriteBatch works with OpenGL ES 1.x and 2.0. In the case of a 2.0 context it will use its own custom shader to draw all provided sprites. You can set your own custom shader via setShader(ShaderProgram).
A PolygonSpriteBatch has to be disposed if it is no longer used.

    Description copied from interface: Batch
    
    Draws a rectangle with the texture coordinates rotated 90 degrees. The bottom left corner at x,y and stretching the region to cover the given width and height. The rectangle is offset by originX, originY relative to the origin. Scale specifies the scaling factor by which the rectangle should be scaled around originX, originY. Rotation specifies the angle of counter clockwise rotation of the rectangle around originX, originY.
    
    Specified by:
    
    draw in interface Batch
    
    clockwise - If true, the texture coordinates are rotated 90 degrees clockwise. If false, they are rotated 90 degrees counter clockwise.

  - setShader
```
public void setShader(ShaderProgram shader)
```
    Description copied from interface: Batch
    
    Sets the shader to be used in a GLES 2.0 environment. Vertex position attribute is called "a_position", the texture coordinates attribute is called "a_texCoord0", the color attribute is called "a_color". See ShaderProgram.POSITION_ATTRIBUTE, ShaderProgram.COLOR_ATTRIBUTE and ShaderProgram.TEXCOORD_ATTRIBUTE which gets "0" appended to indicate the use of the first texture unit. The combined transform and projection matrx is uploaded via a mat4 uniform called "u_projTrans". The texture sampler is passed via a uniform called "u_texture".
    Call this method with a null argument to use the default shader.
    This method will flush the batch before setting the new shader, you can call it in between Batch.begin() and Batch.end().
    
    Specified by:
    
    setShader in interface Batch
    
    Parameters:
    
    shader - the ShaderProgram or null to use the default shader.
  - getShader
```
public ShaderProgram getShader()
```
    Specified by:
    
    getShader in interface Batch
    
    Returns:
    
    the current ShaderProgram set by Batch.setShader(ShaderProgram) or the defaultShader
  - isBlendingEnabled
```
public boolean isBlendingEnabled()
```
    Specified by:
    
    isBlendingEnabled in interface Batch
    
    Returns:
    
    true if blending for sprites is enabled
  - isDrawing
```
public boolean isDrawing()
```
    Specified by:
    
    isDrawing in interface Batch
    
    Returns:
