minSpeed

Syntax

    member(whichCastmember).modelResource(whichModelResource).emitter.minSpeed

Description

3D property; when used with a model resource whose type is `#particle`, allows you to get and set the minimum speed at which particles are emitted. Each particle's initial velocity is randomly selected between the emitter's `minSpeed` and `maxSpeed` properties.

The value is a floating-point number and must be greater than 0.0.

Example

In this example, ThermoSystem is a model resource of the type `#particle`. This statement sets the `minSpeed` property of ThermoSystem to 5, which causes the slowest particles of ThermoSystem to move somewhat slowly. Within a given particle system, the slower a particle moves, the shorter the distance it will travel.

    member("Fires").modelResource("ThermoSystem").emitter.minSpeed = 5
