texmove Library Method
Short Description: Texture animation
Signature: t.texmove (s,t,p,q)
Class: transition Class
Animates the Texture that is mapped on the
object and makes it move from position (s,t) to position (p,q).
These coordinates refer to the position of HTML elements.
In order to make an HTML element's image move over the object, the
object must be smaller than the element. Then at a certain point
in time, only part of the element is shown on the object and that
part changes as the animation is playing.
An initially created transition usually exactly maps the associated
HTML element on the animated object. So the image of the element is
not bigger (but exactly matches) the object and texmove
is not really useful. However, if the object has become
smaller, e.g. using then texmove
can be used to select what part of the element's image shown.
var a=taccgl.actor("testimg"); a.clipA (a.wx0/2,a.hy0/2,a.wx0/2,a.hy0/2).texmove(a.s0,a.t0,a.s0+a.ws0,a.t0+a.ht0); a.start();
