Class JoystickCompatibilityMappings

java.lang.Object

com.jme3.input.JoystickCompatibilityMappings

public class JoystickCompatibilityMappings
extends java.lang.Object

Provides compatibility mapping to different joysticks that both report their name in a unique way and require remapping to achieve a proper default layout.

All mappings MUST be defined before the joystick support has been initialized in the InputManager.

Method Detail

getMappings

                                                                              boolean create)

getButtonMappings

                                                                                    boolean create)

Obtains mappings specific to the joystick buttons

Parameters:

joystickName - - The name of the joystick type to obtain mappings for.

create - - If there are no mappings present and this parameter is true, then a new entry for this joystick is created.

Returns:

The various button remappings for the requested joystick, or null of there are none.

remapAxisRange

public static float remapAxisRange(JoystickAxis axis,

This method will take a "raw" axis value from the system and rescale it based on what the remapper has specified. For example, if the remapper specified an axis to be scaled to [0.0,1.0], then a raw value of -0.5 would be converted to 0.25.

Parameters:

axis - - The axis to remap.

currentValue - - The raw value the system is outputting, on a scale of -1.0 to 1.0.

Returns:

The new value that will be provided to listeners, on a scale specified by the remappings file.

remapAxis

Parameters:

joystickName - - The joystick type the axis comes from.

componentId - - The system-provided name for the axis.

Returns:

The new name for the axis, or just componentId if no remapping was provided.

remapButton

Takes the original name of an button, specifically, and returns the new name it will function under.

Parameters:

joystickName - - The joystick type the axis comes from.

componentId - - The system-provided name for the button.
