public SpriteBatch(int size, ShaderProgram defaultShader)

Constructs a new SpriteBatch. Sets the projection matrix to an orthographic projection with y-axis point upwards, x-axis point to the right and the origin being in the bottom left corner of the screen. The projection will be pixel perfect with respect to the current screen resolution.

The defaultShader specifies the shader to use. Note that the names for uniforms for this default shader are different than the ones expect for shaders set with setShader(ShaderProgram). See createDefaultShader().

Parameters
size:int

The max number of sprites in a single batch. Max of 8191.

defaultShader:ShaderProgram

The default shader to use. This is not owned by the SpriteBatch and must be disposed separately.

public void begin()

Implements com.badlogic.gdx.graphics.g2d.Batch.begin.

Sets up the Batch for drawing. This will disable depth buffer writing. It enables blending and texturing. If you have more texture units enabled than the first one you have to disable them before calling this. Uses a screen coordinate system by default where everything is given in pixels. You can specify your own projection and modelview matrices via setProjectionMatrix(Matrix4) and setTransformMatrix(Matrix4).

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 begin() and end().
