The ValueGradientDriver component changes the value of the field defined in Target
based on the items in the Points
list, and their Position
in relation to the Progress
value.
Fields
Name | Type | Description |
---|---|---|
persistent
|
Bool | Determines whether or not this item will be saved to the server. |
UpdateOrder
|
Int | Controls the order in which this component is updated. |
Enabled
|
Bool | Controls whether or not this component is enabled. |
Progress
|
Float | Controls which items from the Points list will be used to drive the value of Target
|
Target
|
IField<float> | The field that this component will drive the value of |
Interpolate
|
Bool | Controls whether or not this component will interpolate (or blend) between the nearest two Points to the current Progress value.
|
Points
|
SyncList<Point> | A list of items indicating their Position (in relation to Progress ), and a Value
|
Usage
Each point in the Points
list has a Position
field and Value
field. The Position
field is used for comparison with the component's Progress
field, while the Value
field is the value used for driving the field in Target
.
When Interpolate
is checked, the value stored in Target
is linearly interpolated between the Value
s of the two points surrounding the current Progress
. When unchecked, the output value is simply set to the Value
of the closest point before the current Progress
. The only exception to this is when no point exists before the current Progress
, in which case the first point after the current Progress
is used.
If two points have the same Position
, then the point of greatest index takes priority if the value is not interpolated or if the positions are exactly equal to the current Progress
. During interpolation, however, the point of least index takes priority.
Examples
-
General usage of the component, showing interpolation and non-interpolation between five float values.
-
An unorthodox yet valid usage of the component, as way to find the index of the maximum value in a list of floats (as the
Position
values) without the need for ProtoFlux.Progress
may be set to 0 to find the index of the minimum value as well.
