rate
The temporal falloff / attenuation rate.
Declaration
var rate: DoubleDiscussion
An exponent that determines how the effect’s strength diminishes over time. Use a non-negative rate.
When the rate is 0, no falloff occurs.
When the rate is greater than 0 and less than 1.0, falloff occurs slower and is sublinear.
When the rate is 1.0, falloff is linear.
When the rate is greater than 1, falloff occurs faster and is nonlinear.
