ScaleTo Action

Overview

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

Attribute Type Description

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.

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

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.

Instance ID

InstanceID

The assigned Instance ID of the Action. If nothing is received, it automatically assigns 0 as the Instance ID.

(►) Start

Pulse

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

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.

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 $(1000, 1000, 0)$ and its Scale Attribute to $(0.1, 0.1, 0)$ . 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 ScaleTo Action Node with the following Attributes:

To: $(0.4, 0.4, 0)$
Duration (sec): $4$
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:
