Scale affector scales the particle size based on its lifetime and parameters.
ScalingType : enumeration |
Defines the scaling type of the affector.
常量 | 描述 |
---|---|
ScaleAffector3D.Linear
|
The scale is calculated using the easing curve to interpolate between minimum and maximum scale size between duration milliseconds and then continues from the minimum size. |
ScaleAffector3D.SewSaw
|
The scale is calculated using the easing curve to interpolate between minimum and maximum scale size between duration milliseconds on a rising edge then continues from maximum to minimum on a falling edge. |
ScaleAffector3D.SineWave
|
The scale follows the sine wave. Easing curve is not used. |
ScaleAffector3D.AbsSineWave
|
The scale follows the sine wave except negative values are inverted. Easing curve is not used. |
ScaleAffector3D.Step
|
The scale stays at minimum size until half of the duration milliseconds have passed then steps directly to the maximum size. Easing curve is not used. |
ScaleAffector3D.SmoothStep
|
The scale smootly transitions from minimum to maximum size. Easing curve is not used. |
duration : int |
This property holds the duration of scaling cycle in milliseconds. The default is 1000.
easingCurve : EasingCurve |
此特性保持
easing curve
providing more fine tuned control on how the scaling occurs. The easing curve is used with
Linear
and
SewSaw
scaling types. The default easing curve provides linear value between [0, 1].
maxSize : real |
This property holds the maximum size the affector can scale the particle. The default is 1.0.
minSize : real |
This property holds the minimum size the affector can scale the particle. The default is 1.0.
type : ScalingType |
This property holds the scaling type of the affector. The default value is
Linear
.
