Play/Pause/Restart, run/pause/restart
Playback Speed, playback rate
Particle , the number of existing particles

main module

Start Color, the initial color of the particles
Start Speed, the initial speed of the particles (m/s)
Start Size, the initial size of the particles ( m)

Duration, period, the working duration of the particle system
Looping, loop, the particle system only works once/cycles
Prewarm, preheating, material Whether the system should be preheated internally for a cycle first
Start Lifetime, the life time (existence time) of the particles, the default is 5 seconds

Max Particles, the upper limit of the number of particles, default 1000

submodule

Emission, frequency of emission

Launch at a constant speed

1 Rate over Time
Every 1 second, N particles are emitted
2 Rate over Distance
Every time it advances 1 meter, N particles are emitted. For moving objects.

Bursts

Time, the time when the explosion occurred
Count, how many particles were exploded
Cycles / Interval, the number and interval of explosions
Probability, the possible probability of explosion. O means it will not explode (dud bomb)

Explosion other settings
Looping = No, the particle generator only works once
Start Lifetime = 0.2, the particle existence time is extremely short
Start Speed = 30, particles fly extremely fast

Particle number calculation

Consider:
Rate over time = 10
Start Lifetime = 5
Note that particles are reborn and die.
Max Particles, the upper limit of the number of particles, default 1000

Shape, the shape of the particle generator
