Many of the numeric properties of particles or even the whole Particle SystemA component that simulates fluid entities such as liquids, clouds and flames by generating and animating large numbers of small 2D images in the scene. More info
See in Glossary can vary over time. Unity provides several different methods of specifying how this variation happens:
When you set a property to Curve or Random Between Two Curves, the Particle System Curves editor appears at the bottom of the InspectorA Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info
See in Glossary:
To edit a curve, click and drag an end point or key to reshape the curve:
Particle System curves are similar to Animation curvesAllows you to add data to an imported clip so you can animate the timings of other items based on the state of an animator. For example, for a game set in icy conditions, you could use an extra animation curve to control the emission rate of a particle system to show the player’s condensing breath in the cold air. More info
See in Glossary. For information on using curves, see the documentation on Editing Curves.
The Particle System Curves editor has the following buttons:
To edit the way in which the Particle System plays curves, click the cog next to a selected key and choose one of the following options:
The Start Color property in the main module has the following options:
Other color properties, such as Color over Lifetime, can use the Gradient or Random Between Two Gradients modes.
To calculate the final particle color result, the Particle System multiplies color properties in various modules together per channel.
When you set the Gradient color for particles, the Gradient Editor appears:
Color properties in various modules are multiplied together per channel to calculate the final particle color result.
