Particles are two-dimensional images that are rendered in three-dimensional space and are mainly used to represent smoke, fire, water droplets, and deciduous leaves in the scene 、...... and many other effects.

An important feature of unity particle systems (particle system) is that independent particle systems can be grouped by parent-child to the same root, where all particles have their own particle effects (particle Effect), but these particles in the particle system can play together, Stop, pause. Second, the new particle system and the old version of the particle system

Unity recommends using a new version of Particle System Builder (Section 9.1, 1, Mode 2) to produce a variety of particle effects. In addition, you can use the old particle system (Legacy particles) to make particle effects.

The Legacy particle system (Legacy particles) is a particle system generator provided by the previous version of Unity 3.5, which consists of a particle emitter (ellipsoid particle emitter ellipsoidparticleemitter, Mesh particle emitter meshparticleemitter), particle animator (Particleanimator, Worldparticlecollider), and particle renderer (particlerenderer) three separate parts. As shown in the following:

If you want to use it to create a static particle effect, you can use the particle emitter with the particle renderer, and the particle animator will move the particles in different directions and transform their colors, or script to control each individual particle in the particle system.

Since the Unity 5.x recommends using the new particle system generator (particle system) to make the particle effect, and the legacy particle system generator is obsolete, preserving the old version is only to keep the particles that have been used to make it compatible with the original, perhaps to which version will start no longer support, So the legacy particle system generator is no longer introduced.
