How to do it...
Now, we can begin creating the muzzle flash emitter:
1. Navigate to the
Emitters
folder in the project and select
New.../Empty jme3
Scene
. We should now have a fresh scene.
2. Right-click on the main node in the
SceneExplorer
window and select
Add Spa-
tial/Particle Emitter
.
3. Select the emitter instance and open the
Properties
window.
4. Make sure the
Shadow Mode
option is
Off
and
Queue Bucket
is
Transparent
.
5. Then, select the muzzle flash material we created in the
Geometry/Material
sec-
tion.
6. Make the
Emitter
shape really small, for example, something like
[Sphere,
0.0, 0.0, 0.0, 0.05]
.
7.
Num Particles
should be
1
, and
Particles Per Sec
should be
0.0
.
8. Set
Start Color
to something like
[1.0, 1.0, 0.4, 1.0]
and
End Color
to
[1.0, 0.6, 0.2, 0.7]
.
9. Both
Start Size
and

should be
1.0
.
10.
High Life
and
Low Life
should be
0.15
.
11.
Gravity
and
Face Normal
should be
[0.0, 0.0, 0.0]
.
12. Check the
Facing Velocity
box and set the
Initial Velocity
to
[0.0, 0.0,
1.0]
.
13.
Images X
and

should reflect the number of frames in the texture we cre-
ated.
14. We can now test the emitter by clicking on the
