In Listing 9-10 we can see that
Flare
extends
ImageView
and shows the
Image
flareImage
. The
init
function sets the effect to a
ColorAdjust
with a random value; the value
deltaRotation
is also set to a random
value as well as the starting rotation. When the
Timeline
anim
from the class
DiscoStar
calls the function
update
, this class behaves much like some of the other particles we have looked at. First we check to see
whether the particle is done living as tracked by the value of
currentStep
. If the particle is still alive, it is
rotated a little bit, and it becomes more transparent. Figure 9-5 shows what one
Flare
looks like.
