# RotateBy Action

## Overview

![The RotateBy Action Node.](/files/rtApXMiJ43RZehUQjCFV)

The **RotateBy Action Node** continuously rotates an [**Object**](/incari-studio/2022.2/objects-and-types/scene-objects.md) by the *Euler angles* values specified in `Offset` 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/2022.2/toolbox/actions.md) page for a general introduction to these **Nodes**, and [**Rotation**](/incari-studio/2022.2/objects-and-types/attributes/common-attributes/transformation.md#rotation) for more detail about the `Rotation` **Attribute**.

[**Scope**](/incari-studio/2022.2/toolbox/overview.md#scopes): **Scene**, **Function**, **Prefab**.

## Example

This section shows a simple example of how to use the **RotateBy 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/2022.2/objects-and-types/project-objects/scene.md) with two [**Objects**](/incari-studio/2022.2/objects-and-types/scene-objects.md): a red [**Torus**](/incari-studio/2022.2/objects-and-types/scene-objects/primitives.md#torus) and a [**Directional Light**](/incari-studio/2022.2/objects-and-types/scene-objects/lights.md), both of which can be easily created in the [**Scene Outliner**](/incari-studio/2022.2/modules/scene-outliner.md). Then, we set the `Scale` **Attribute** of the **Torus** to $$(2, 2, 2)$$, its `Rotation` to $$(30, 30, 0)$$, and the `Position` of the **Light** to $$(0, 200, 0)$$. See this configuration in the following image:

![Scene configuration.](/files/zRv3Hlj6kpuNvUKUxI9a)

### Logic

We then need to configure the **Logic**. This is done in the [**Logic Editor**](/incari-studio/2022.2/modules/logic-editor.md).

We use first a [**Get Rotation** **Node**](/incari-studio/2022.2/toolbox/incari/object/get-rotation.md), which allows us to obtain an **Object's** current `Rotation` values, and then the **RotateFromTo Action** **Node**, to which we will feed the value previously obtained and configure it for it to *rotate* the **Object** from there to a fixed value of our choosing.

We use the **RotateBy Action** **Node** with the following **Attributes**:

* `Offset`: $$(60, 60, 0)$$
* `Duration (sec)`: $$3$$
* `Interpolation`: `Linear`

And we connect to it the [**Object Node**](/incari-studio/2022.2/objects-and-types/scene-objects.md#objects-in-the-logic) of the red **Torus** and a **Pulse** to the `Start` **Input Socket**. Thus, having the following **Logic** configuration:

### Final result

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