3D: Controlling action
Using interpolateTo() gives a natural lag between the movement of the avatar and the movement of the camera
In the ElasticCamera.dir movie, take a look at the Elastic Third Person Camera script. The on stepFrame() handler
includes a command similar to the following.
sprite(1).camera.transform.interpolateTo(aRestTransform, 10.0)
Launch the movie and the following commands in the Message window. You will observe that the avatar moves
backwards and to the left, moving halfway towards the position vector(-125, 0, 250) and rotating halfway towards
the rotation vector(0, -45, 0). The camera will move smoothly after this point, using interpolateTo() several times
on successive frames, until it comes to rest giving the view shown in the screenshot above.
-- Lingo
vAvatarTransform = member("3D").group("Avatar_Parent").transform
vTargetTransform = transform()
vTargetTransform. position = vector(-125, 0, 250)
vTargetTransform. rotation = vector(0, -45, 0)
vAvatarTransform.interpolateTo(vTargetTransform, 50.0)
// Javascript
vAvatarTransform = member("3D").getPropRef("group", 2).transform
vTargetTransform = transform();
vTargetTransform. position = vector(-125, 0, 250);
vTargetTransform. rotation = vector(0, -45, 0);
vAvatarTransform.interpolateTo(vTargetTransform, 50.0);
Following a path
You don't always want to move a node along a straight path. This article explains one way to move a node along a
curved path. You can find an alternative solution at “Keyframe animations” on page 274.
To visualize the technique described here, download and launch the movie Tubing.dir.
