# Flipbook Player Menu Path : **FlipBook > Flipbook Player** The **Flipbook Player** Block creates animated particles using flipbook textures. To do this, it increments each particle's **Tex Index** attribute over time. Flipbook textures are texture sheets that consist of multiple smaller sub-images. To produce an animation, Unity steps through the sub-images in a particular order. ![](Images/Block-FlipbookPlayerExampleLHS.png)![img](Images/Block-FlipbookPlayerExampleRHS.gif) To generate a Flipbook, use external digital content creation tools. To set an output to use flipbooks, change its **UV Mode** to **Flipbook**, **Flipbook Blend**, or **Flipbook Motion Blend**. For more information on the different UV Modes, see the documentation for the various output Contexts. ## Block compatibility This Block is compatible with the following Contexts: - [Update](Context-Update.md) ## Block settings | **Setting** | **Type** | **Description** | | ----------- | -------- | ------------------------------------------------------------ | | **Mode** | Enum | Specifies how to define the frame rate for the flipbook, in frames per second. The options are:
• **Constant**: Uses a constant frame rate.
• **Curve**: Uses a curve to control the frame rate. The curve defines the frame rate over the lifetime of the particle. | ## Block properties | **Input** | **Type** | **Description** | | -------------- | -------- | ------------------------------------------------------------ | | **Frame Rate** | Float | Sets the flipbook rate in image frames per second. This property only appears if you set **Mode** to **Constant.** | | **Frame Rate** | Curve | Sets the flipbook rate, in image frames per second, over the particle lifetime via a curve. The curve value at time 0 is the frame rate when a particle is born, and the value at time 1 is the frame rate when the particle reaches its lifetime.
