FadeTo Action
Overview
The FadeTo Action Node continuously modifies the Opacity
of an Object over a specified period of time, thus creating an Animation. The final value of the Opacity
is set by the user. Find an example of how to use this Node and its effect over an Object at the end of this page.
Furthermore, visit the Actions Nodes page for a general introduction to these Nodes.
Scope: Scene, Function, Prefab.

Example
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.
Scene Configuration
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:
Logic
We then need to configure the Logic. This is done in the Logic Editor.
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:
Final result
Finally, the effect of the ScaleTo Action Node when triggered is the following:
