Line 202 should be changed from
[java]
matBullet.setColor("m_GlowColor", ColorRGBA.Green);
[/java]
to
[java]
matBullet.setColor("GlowColor", ColorRGBA.Green);
[/java]
Also, the particle emitter setup code uses deprecated methods, it does not result in a runtime exception though, line 220,221 should be:
[java]
effect.getParticleInfluencer().setInitialVelocity(new Vector3f(0, 7, 0));
effect.getParticleInfluencer().setVelocityVariation(1f);
[/java]
