Class VJointMoveControl

java.lang.Object
  hmi.animation.VJointMoveControl

All Implemented Interfaces:

ClockListener

public class VJointMoveControl
extends Object
implements ClockListener

This class uses keyboard input to move an object around. The keyboard input is taken from a keystate determined by a certain Component. Keys: A and D move left and right, W and S move back and forth, Left and right "arrow" keys rotate, Up and down "arrow" keys move back and forth. PageUp and PageDown move up and down. This object is initialized with the VJoint it is supposed to move around. Also, at init time you say whether the keys should be inverted -- this makes the VJointMoveControl usable as a navigationcontrol (moving the scene in inverted way means moving the person view in normal way...) One can pass required keymodifiers KeyEvent.VK_CONTROL/VK_ALT/VK_SHIFT at construction time The control should be connected to a clock -- every clock tick, the controlled VJoint is updated

protected void applyLimits()

correctModifiers

private boolean correctModifiers(KeyState keyState)

Returns true if the keystate contains exactly those modifiers with which this control was initialized

initTime

public void initTime(double time)

Description copied from interface: ClockListener

initTime() is called before the Clock starts running, and sends some initial time value. This will often equal the time send for the first regular time() call. This is done on the same clock Thread that is going to send the regular time() calls.

Specified by:

initTime in interface ClockListener

time

public void time(double currentTime)

Every clock tick, - check the new movements from the keystate, depending on the pressed keys - update the position and orientation of the controlled object

Specified by:

time in interface ClockListener
