Field Detail

keycode

public TypedIOPort keycode

An output port that contains the keycode for a key pressed on the viewscreen. The default type is int.

_userInputNode

protected javax.media.j3d.BranchGroup _userInputNode

The BranchGroup to which is listened for key presses.

_hasData

protected boolean _hasData

True if this actor has data.

Constructor Detail

KeyInput3D

public KeyInput3D(CompositeEntity container,
                  java.lang.String name)
           throws IllegalActionException,
                  NameDuplicationException

Construct an actor with the given container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.

Method Detail

fire

public void fire()
          throws IllegalActionException

If a key has been pressed, send the keycode to the keycode port. If no key has been pressed, then no data is sent.

Specified by:

fire in interface Executable

Overrides:

fire in class GRActor

Throws:

IllegalActionException - If thrown while sending the data to the output port.

initialize

public void initialize()
                throws IllegalActionException

Set up this actor to listen to key presses.

Specified by:

initialize in interface Initializable

Overrides:

initialize in class GRActor

Throws:

IllegalActionException - If thrown by the parent class.

_getNodeObject

protected javax.media.j3d.Node _getNodeObject()

Get the user input BranchGroup node.

Specified by:

_getNodeObject in class GRActor3D

Returns:

The user input BranchGroup node for this actor.

_makeSceneGraphConnection

protected void _makeSceneGraphConnection()
                                  throws IllegalActionException

Add this node to the viewscreen.

Specified by:

_makeSceneGraphConnection in class GRActor

Throws:

IllegalActionException - If throw while adding this node to the viewscreen.
