Module
Description
Rotation over Lifetime module
Designate the angular velocity of the particles over
their lifetime with a constant or a curve. Also has
options for randomization between two constants or
two curves.
Rotation by Speed module
Same options as Rotation over Lifetime, though you
must designate the range of speeds since it is not
predetermined by the Duration property as in the
previous module.
External Forces module
This module is specifically designed for designating
the extent to which the particles are affected by wind
zones.
Collision module
First select whether the particles will recognize
collisions with every game object or be limited to
planes. Using planes whenever possible is the most
efficient for game performance.
Visualization of the planes lets you choose between
using wireframe-like or solid grids. The remaining
parameters affect particle behavior similarly to
Rigidbody and Physic Materials.
Send Collision Messages calls the
OnParticleCollision()
function when checked.
Sub Emitters module
Particles can be designated to convert to another
Particle System either on collision or at the beginning
or end of its lifetime. Using the Collision option
requires enabling of the Collision Module. You can
find an excellent example of sub emitters at work with
the fireworks in the Particle Sandbox scene of the
Sample Assets particle system demo.
