Class GLProfiler

java.lang.Object

com.badlogic.gdx.graphics.profiling.GLProfiler

public class GLProfiler
extends 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.

Constructor Detail

GLProfiler

public GLProfiler(Graphics graphics)

Create a new instance of GLProfiler to monitor a Graphics instance's gl calls

Parameters:

graphics - instance to monitor with this instance, With Lwjgl 2.x you can pass in Gdx.graphics, with Lwjgl3 use Lwjgl3Window.getGraphics()

Method Detail

enable

public void enable()

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

disable

public void disable()

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

setListener

public void setListener(GLErrorListener errorListener)

Set the current listener for the GLProfiler to errorListener

getListener

public GLErrorListener getListener()

Returns:

the current GLErrorListener

isEnabled

public boolean isEnabled()

Returns:

true if the GLProfiler is currently profiling

getCalls

public int getCalls()

Returns:

the total gl calls made since the last reset

getTextureBindings

public int getTextureBindings()

Returns:

the total amount of texture bindings made since the last reset

getDrawCalls

public int getDrawCalls()

Returns:

the total amount of draw calls made since the last reset

getShaderSwitches

public int getShaderSwitches()

Returns:

the total amount of shader switches made since the last reset

getVertexCount

public FloatCounter getVertexCount()

Returns:

FloatCounter containing information about rendered vertices since the last reset

reset

public 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.
