Rarely do particles alone handle the job of a special effect. In most cases, you will need to combine particles, lights, sounds, and other elements to achieve your goal. This example shows how a Blueprint can be created in order to combine a Particle System with a light and sound effect. The effect is a simple Blueprint Class deriving from Actor. It contains the following Components:
The P_spark_burst Particle System.
A Sound Component that plays the sparks sound effect.
A Light Component to supply a dynamic flash of light.
The graph for the Blueprint defines a very simple behavior:
First, we calculate a random delay factor.
Once that random delay finishes, we fire the Particle System and then the sound effect.
We use a Timeline node to animate the brightness of the Light Component to cause the visible illumination of the flash.
Since the Particle System is set up to only fire a single burst, we get a nice single "pop" of particles that coincides beautifully with the light and sound.
