Class MaterialDebugAppState

java.lang.Object

com.jme3.app.state.AbstractAppState

com.jme3.util.MaterialDebugAppState

All Implemented Interfaces:

AppState

public class MaterialDebugAppState
extends AbstractAppState

This appState is for debug purpose only, and was made to provide an easy way to test shaders, with a live update capability. This class provides and easy way to reload a material and catches compilation errors when needed and displays the error in the console. If no error occur on compilation, the material is reloaded in the scene. You can either trigger the reload when pressing a key (or whatever input is supported by Triggers you can attach to the input manager), or trigger it when a specific file (the shader source) has been changed on the hard drive. Usage : MaterialDebugAppState matDebug = new MaterialDebugAppState(); stateManager.attach(matDebug); matDebug.registerBinding(new KeyTrigger(KeyInput.KEY_R), whateverGeometry); this will reload the material of whateverGeometry when pressing the R key. matDebug.registerBinding("Shaders/distort.frag", whateverGeometry); this will reload the material of whateverGeometry when the given file is changed on the hard drive. you can also register bindings to the appState with a post process Filter

Method Detail

initialize

public void initialize(AppStateManager stateManager,
                       Application app)

Description copied from interface: AppState

Called by AppStateManager when transitioning this AppState from initializing to running.
This will happen on the next iteration through the update loop after AppStateManager.attach(com.jme3.app.state.AppState) was called.

AppStateManager will call this only from the update loop inside the rendering thread. This means is it safe to modify the scene graph from this method.

Specified by:

initialize in interface AppState

Overrides:

initialize in class AbstractAppState

Parameters:

stateManager - The state manager

app - The application

registerBinding

public void registerBinding(Trigger trigger,
                            Spatial spat)

Will reload the spatial's materials whenever the trigger is fired

Parameters:

trigger - the trigger

spat - the spatial to reload

registerBinding

public void registerBinding(Trigger trigger,
                            Filter filter)

Will reload the filter's materials whenever the trigger is fired.

Parameters:

trigger - the trigger

filter - the filter to reload

registerBinding

public void registerBinding(java.lang.String shaderName,
                            Filter filter)

Will reload the filter's materials whenever the shader file is changed on the hard drive

Parameters:

shaderName - the shader name (relative path to the asset folder or to a registered asset path)

filter - the filter to reload

registerBinding

public void registerBinding(java.lang.String shaderName,
                            Spatial spat)

Will reload the spatial's materials whenever the shader file is changed on the hard drive

Parameters:

shaderName - the shader name (relative path to the asset folder or to a registered asset path)

spat - the spatial to reload

reloadMaterial

public Material reloadMaterial(Material mat)

update

public void update(float tpf)

Description copied from interface: AppState

Called to update the AppState. This method will be called every render pass if the AppState is both attached and enabled.

Specified by:

update in interface AppState

Overrides:

update in class AbstractAppState

Parameters:

tpf - Time since the last call to update(), in seconds.
