FadeTo Action

The FadeTo Action Node.

The FadeTo Action Node Attributes.
Attribute | Type | Description |
---|---|---|
Duration (sec) | Float | The total time of the Action, if none is received in the Duration Input Socket. |
To | Float | The desired Opacity value at the end of the Action, if none is received in the To Input Socket. |
Interpolation | Drop-down | The Interpolation method to use for calculating the intermediate values of the Opacity . It can be Linear, Sine Ease In, Sine Ease In Out, or Sine Ease Out. |
Input | Type | Description |
---|---|---|
Instance ID | InstanceID | The assigned Instance ID of the Action. If nothing is received, it automatically assigns 0 as the Instance ID. |
(►) Start | Pulse | A standard Input Pulse, to trigger the execution of the Node. |
Object ID | ObjectID | The ID of the target Object. |
Duration | Float | The total time (in seconds). |
To | Float | The desired Opacity value at the end of the Action. |
Output | Type | Description |
---|---|---|
Instance ID | InstanceID | |
OnStart (►) | Pulse | Flows to the next Node following FadeTo Action when the Action starts. |
OnEnd (►) | Pulse | Flows to the next Node following FadeTo Action when the Action stops. |
This section shows a simple example of how to use the FadeTo Action Node and the effect it has on an Object. We start by configuring the Scene, then build the Logic, and finally show the result.
We consider a Scene with two Objects: a white arc over a black background, both of which can be easily created in the Scene Outliner. Then, we set the
Size
Attribute of the arc to . See this configuration in the following image:

Scene configuration.
We use the FadeTo Action Node with the following Attributes:
Duration (sec)
:To
:Interpolation
:Linear
And we connect to it the Object Node of the arc and a Pulse to the
Start
Input Socket. Thus, having the following Logic configuration:
Logic configuration.
Finally, the effect of the ScaleTo Action Node when triggered is the following:

Final result.
