Method Details

begin
void 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 viasetProjectionMatrix(Matrix4)
andsetTransformMatrix(Matrix4)
. -
end

getShader
ExtShaderProgram getShader()- Returns:
- the current
ExtShaderProgram
set bysetShader(ExtShaderProgram)
or the defaultShader
-
setShader
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". SeeExtShaderProgram.POSITION_ATTRIBUTE
,ExtShaderProgram.COLOR_ATTRIBUTE
andExtShaderProgram.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()
andend()
.- Parameters:
shader
- theExtShaderProgram
or null to use the default shader.
-
isBlendingEnabled
boolean isBlendingEnabled()- Returns:
- true if blending for sprites is enabled
-
isDrawing
boolean isDrawing()- Returns:
- true if currently between begin and end.
