# ScaleTo Action

## Overview

![The ScaleTo Node.](/files/nBNhPaoTTNq5immjbIpi)

The **ScaleTo Action Node** continuously scales an [**Object**](/incari-studio/2024.1/objects-and-types/scene-objects.md) to the `Scale` values specified in `To` for a given period of time, thus creating an **Animation**. Find an [example](#example) of how to use this **Node** and its effect over an **Object** at the end of this page.

Furthermore, visit the [**Actions Nodes**](/incari-studio/2024.1/toolbox/actions.md) page for a general introduction to these **Nodes**, and [**Scale**](/incari-studio/2024.1/objects-and-types/attributes/common-attributes/transformation.md#scale) for more detail about the `Scale` **Attribute**.

[**Scope**](/incari-studio/2024.1/toolbox/overview.md#scopes): **Scene**, **Function**, **Prefab**.

## 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**](#scene-configuration), then [build the **Logic**](#logic), and finally show the [result](#final-result).

### Scene Configuration

We consider a [**Scene**](/incari-studio/2024.1/objects-and-types/project-objects/scene.md) with two [**Objects**](/incari-studio/2024.1/objects-and-types/scene-objects.md): a red ellipse over a black background, both of which can be easily created in the [**Scene Outliner**](/incari-studio/2024.1/modules/scene-outliner.md). 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:

![Scene configuration.](/files/yLaqzEcJcWhXzQs8Xaq2)

### Logic

We then need to configure the **Logic**. This is done in the [**Logic Editor**](/incari-studio/2024.1/modules/logic-editor.md).

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**](/incari-studio/2024.1/objects-and-types/scene-objects.md#objects-in-the-logic) of the red ellipse and a **Pulse** to the `Start` **Input Socket**. Thus, having the following **Logic** configuration:

![Logic configuration.](/files/pW6Nr03rppRP1ufJRGwN)

### Final result

Finally, the effect of the **ScaleTo Action** **Node** when triggered is the following:
