2. Then, create a PlayEffect instance for each of ParticleEmitters and set
the effect accordingly with emitAllParticles set to true .
3. Create a new Timer instance called explosionTimer .
4. Add a new TimerEvent at time 0 where it triggers the flash , spark ,
smoke , debris , and shockwave effects, by calling trigger() on each of
the PlayEffects , as shown in the following code:
explosionTimer.addTimerEvent(0, new
Timer.TimerEvent() {
public Object[] call() {
flashEffect.trigger();
sparkEffect.trigger();
...
return null;
}
});
5. Then, add another TimerEvent at time 0.05f , which triggers the flame and
roundSpark effects.
6. The last TimerEvent should happen at time 5f and should call stop() on all
of the effects.
7. Finally, we create a ScriptAppState instance to which we add explo-
sionTimer and then add it to stateManager using the following code:
ScriptAppStateappState = new ScriptAppState();
stateManager.attach(appState);
appState.addScriptObject(explosionTimer);
8. Now, we can trigger explosionTimer . It should perform the explosion in the
same way as TestExplosion does.
