Class GLProfiler

java.lang.Object

com.badlogic.gdx.graphics.profiling.GLProfiler

Direct Known Subclasses:

GL20Profiler, GL30Profiler

public abstract class GLProfiler
extends java.lang.Object

When enabled, collects statistics about GL calls and checks for GL errors. Enabling will wrap Gdx.gl* instances with delegate classes which provide described functionality and route GL calls to the actual GL instances.

Field Summary

Fields

Modifier and Type	Field and Description
static int	calls All calls to any GL function since the last reset.
static int	drawCalls The amount of draw calls that happened since the last reset.
static GLErrorListener	listener This listener will be called when GLProfiler is enabled and any GL call sets an error number (retrievable by glGetError call).
static int	shaderSwitches The amount of times a shader was switched since the last reset.
static int	textureBindings The amount of times a texture binding has happened since the last reset.
static FloatCounter	vertexCount The amount rendered vertices since the last reset.

static void	enable() Enables profiling by replacing the GL20 and GL30 instances with profiling ones.
static boolean	isEnabled()
static void	reset() Will reset the statistical information which has been collected so far.

Field Detail

calls

public static int calls

All calls to any GL function since the last reset.

textureBindings

public static int textureBindings

The amount of times a texture binding has happened since the last reset.

drawCalls

public static int drawCalls

The amount of draw calls that happened since the last reset.

shaderSwitches

public static int shaderSwitches

The amount of times a shader was switched since the last reset.

vertexCount

public static final FloatCounter vertexCount

The amount rendered vertices since the last reset.

listener

public static GLErrorListener listener

This listener will be called when GLProfiler is enabled and any GL call sets an error number (retrievable by glGetError call). Default is GLErrorListener.LOGGING_LISTENER.

Constructor Detail

GLProfiler

public GLProfiler()

Method Detail

resolveErrorNumber

public static java.lang.String resolveErrorNumber(int error)

enable

public static void enable()

Enables profiling by replacing the GL20 and GL30 instances with profiling ones.

disable

public static void disable()

Disables profiling by resetting the GL20 and GL30 instances with the original ones.

isEnabled

public static boolean isEnabled()

Returns:

Whether profiling is currently enabled

reset

public static void reset()

Will reset the statistical information which has been collected so far. This should be called after every frame. Error listener is kept as it is.
