6. The dialog panel will have four
<panel>
elements inside it. At the top and bot-
tom, we should add two thin panels with black background to give it a cinematic
feel.
7. The upper part of the two central panels will contain the
characterControl
we just created:
<control name="characterControl" id="character"/>
8. The lower one will have a listbox that contains the player's dialog options:
<control id="dialogOptions" name="listBox"
vertical="off" horizontal="off" displayItems="3"
selection="Single"/>
9. If we also want support for the options menu, it should go in a separate layer to
make it show on top of the rest of the GUI.
The controller code for it can be created by performing the following 12 steps:
1. Begin by defining a new class called
DialogScreenController
that ex-
tends
NiftyController
or implements
ScreenController
if an abstract
Controller
class is not available.
2. Next, we add two fields: one for the current
DialogNode
,
dialogNode
, and a
reference to
ListBox
in the XML called
dialogOptions
.
3. The
onStartScreen()
method should be overridden; here, it should set
dialogOptions
by calling
screen.findNiftyControl
:
dialogOptions =
screen.findNiftyControl("dialogOptions",
ListBox.class);
4. Finally,
onStartScreen
should also call
onDialogNodeChanged()
if
dialogNode
is set.
5. Now, we need to define the method called
onDialogNodeChanged
that will
apply the dialog information to the layout.
