FadeFromTo Action
Overview
The FadeFromTo Action Node continuously modifies the Opacity
of an Object over a specified period of time, thus creating an Animation. Both the initial and final values of the Opacity
are chosen 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 FadeFromTo 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
Logic
We then need to configure the Logic. This is done in the Logic Editor.
We use first a Get Opacity Node, which allows us to obtain an Object's current Opacity
value, and then the FadeFromTo Action Node, to which we will feed the value previously obtained and configure it for it to change it from there to a fixed value of our choosing.
For this purpose, we set the Attributes of the FadeFromTo Action Node in the following way:
Interpolation
:Linear
We just leave the From
Attribute as it is, since this value will be obtained through the corresponding Input Socket.
Then, we connect the Object ID from the white arc Object Node to the Object ID
Input Socket of both Nodes, the Opacity
Output from the Get Opacity Node to the From
Input Socket in the FadeFromTo Node, and a Pulse through the Get Opacity Node and to the Start
Input in FadeFromTo. Thus, having the following Logic configuration:
Final result
Finally, the effect of the FadeFromTo Action Node when triggered is the following:
