In the previous section, we created a realistic explosion by simply adding three lines of code. We can customize many parameters of a particle system. For instance, we could modify how much we would like our particle system to expand by modifying the life property.

We could also modify how big or how small we would want our particle system to be at the beginning and the size that we want it to have at the end, by setting the values to the startSize property and the endSize property. For example, if we would like to simulate the turbine of a rocket, then we could configure the emitter to start with a small size and to end with a big size.

We can adjust the angle to which the particle is going to move by modifying the angle property. You can assign random angles to your particle systems, so that it will look more realistic.

The particle systems can have two modes, radius and gravity. The most common particle systems use the gravity mode, on which we can parameterize...
