drag

Syntax

    member(whichCastmember).modelResource(whichModelResource).drag

Description

3D `#particle` model resource property; indicates the percentage of each particle's velocity that is lost in each simulation step. This property has a range of 0 (no velocity lost) to 100 (all velocity lost and the particle stops moving). The default value is 0.

Example

In this example, ThermoSystem is a model resource whose type is `#particle`. This statement sets the `drag` property of ThermoSystem to 5, applying a large resistance to the motion of the particles of ThermoSystem and preventing them from traveling very far.

    member("Fires").modelResource("ThermoSystem").drag = 5
