How to do it...
So now that we have a scene prepared with some waypoints we can get to work with im-
plementing the cutscene itself by performing the following steps:
1. We start by loading a scene where the
Cinematic
will be played out. The scene
reference will be used in several places, so it is a good idea to store it in a field.
2. We'll also create a
Spatial
field called Jaime, the main actor and either load or
extract him from the scene (depending on the setup).
3. Now, we can create a
MotionPath
instance called
jaimePath
for Jaime. Since
we created
Nodes
for each waypoint in
SceneComposer
, we can get their loca-
tion from the scene by using:
jaimePath.addWayPoint(scene.getChild("WayPoint1").getWorldTranslation());
4. We go on and create a
MotionEvent
called
jaimeMotionEvent
using
jaimePath
and
initialDuration
of 25 seconds:
jaimeMotionEvent = new MotionEvent(jaime, jaimePath,
25f);
5. It's also preferable if Jaime faces in the direction of the path he travels along, so we
also set
directionType
to
MotionEvent.Direction.Path
.
Before we get too far, we want to check out that the path Jaime follows is alright. There-
fore, we should go ahead and create a
Cinematic
instance at this point. To do this, per-
form the following steps:
1. Doing this is as simple as supplying it with a scene, which will affect
rootNode
together with the total duration of the cinematic:
cinematic = new Cinematic(scene, 60f);
2. After that, we add
MotionEvent
with the following line; 0 being the time it
should start at:
cinematic.addCinematicEvent(0, jaimeMotionEvent);
3. We also need to add cinematic to the
stateManager
of the application with
stateManager.attach(cinematic)
.
