ScaleTo Action

Overview

The ScaleTo Node.
The ScaleTo Action Node continuously scales an Object to the Scale values specified in To for a given period of time, thus creating an Animation. 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, and Scale for more detail about the Scale Attribute.
Scope: Scene, Function, Prefab.

Attributes

The ScaleTo Node Attributes.
Attribute
Type
Description
To
Vector3
The desired final Scale values along the X, Y, Z axes, if none are given in the To Input Socket.
Duration (sec)
Float
The total time of the Action, if none is given in the Duration Input Socket.
Interpolation
Drop-down
The Interpolation method to use for calculating the intermediate values of the Scale. It can be Linear, Sine Ease In, Sine Ease In Out, or Sine Ease Out.

Inputs

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
Vector3
The desired final Scale values along the X, Y, Z axes.

Outputs

Output
Type
Description
Instance ID
InstanceID
The assigned Instance ID of the Action.
OnStart (►)
Pulse
Flows to the next Node following ScaleTo Action when the Action starts.
OnEnd (►)
Pulse
Flows to the next Node following ScaleTo Action when the Action stops.

Example

This section shows a simple example of how to use the ScaleTo 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 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
(1000,1000,0)(1000, 1000, 0)
and its Scale Attribute to
(0.1,0.1,0)(0.1, 0.1, 0)
. See this configuration in the following image:
Scene configuration.

Logic

We then need to configure the Logic. This is done in the Logic Editor.
We use the ScaleTo Action Node with the following Attributes:
  • To:
    (0.4,0.4,0)(0.4, 0.4, 0)
  • Duration (sec):
    44
  • 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:
Logic configuration.

Final result

Finally, the effect of the ScaleTo Action Node when triggered is the following:
Final result.
