This simple scene shows how to handle a particle system to create smoke. There are two modules being used
SmokeSourcedefines a place from where smoke puffs spawn and an interval. To instance smoke puffs, it either uses idle entities from an object pool or creates new ones if they don't exist yet.
Smokeupdates the position of the existing smoke puffs so that they rise and slowly move in a direction set by their
SmokeVelocitycomponent. When a smoke puff is too far from the source, it's removed from the scene.
