Build a Rocket Launcher! - Unity 4 Game Development - page 388

Objective complete - mini debriefing
In this section, we created the RocketUI script to show the number of bullets left on the
screen. The script will automatically update the number of bullets we have left when we
click on fire or reload .
Next, we created the RocketLauncher object and script to fire the rocket, which will show
the Smoke particle when we click on fire by getting the playbackTime value from the
current animation using AnimationStateInfo . We get the time left for the current an-
imation to finish by using currentState.normalizedTime % 1 to calculate the
remaining time and pass it to BroadcastMessage ("Fire", playbackTime) to
trigger the Fire event.
