ScaleBy Action

The ScaleBy Action Node continuously scales an Object, thus creating an Animation. The final values of the Scale
Attribute are determined by multiplying the initial ones with the values specified by the user in either the Attribute or Input Socket By
of the Node. Find an example of how to use this Node and its effect over an Object at the end of this page.
The following table shows several examples of how the Scale
values of an Object change for different By
values:

Final Scale

Attribute.
Scope: Scene, Function, Prefab.

This section shows a simple example of how to use the ScaleBy 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 then need to configure the Logic. This is done in the Logic Editor.
We use the ScaleBy Action Node with the following Attributes:
Interpolation
: Linear
And we connect to it the Object Node of the red ellipse and a Pulse to the Start
Input Socket. Thus, having the following Logic configuration:
Finally, the effect of the ScaleBy Action Node when triggered is the following:

We consider a Scene with two Objects: a red ellipse over a black background, both of which can be easily created in the Scene Outliner. Then, we set the Size
Attribute of the ellipse to and its Scale
Attribute to . See this configuration in the following image:
