tweenMode

Syntax

    member(whichCastmember).modelResource(whichModelResource).
    tweenMode
    modelResourceObjectReference.tweenMode

Description

3D particle property; allows you to get or set whether the color of a particle varies according to it's speed or age. The `tweenMode` property can have the following values:

| `#velocity` alters the color of the particle between `colorRange.start` and `colorRange.end` based on the velocity of the particle.
| `#age` alters the color of the particle by linearly interpolating the color between `colorRange.start` and `colorRange.end` over the lifetime of the particle. This is the default setting for this property.

Example

In this example, ThermoSystem is a model resource of the type #particle. This statement sets the ThermoSystem's tweenMode to #velocity, so its slower particles will not reach the color specified by colorRange.end, while its faster particles will.

    member(8,2).modelResource("thermoSystem").tweenMode = #velocitytype (light)
