Phaser API Documentation

Description:

Creates a new Render Texture Game Object and adds it to the Scene.

Note: This method will only be available if the Render Texture Game Object has been built into Phaser.

A Render Texture is a combination of Dynamic Texture and an Image Game Object, that uses the Dynamic Texture to display itself with.

A Dynamic Texture is a special texture that allows you to draw textures, frames and most kind of Game Objects directly to it.

You can take many complex objects and draw them to this one texture, which can then be used as the base texture for other Game Objects, such as Sprites. Should you then update this texture, all Game Objects using it will instantly be updated as well, reflecting the changes immediately.

It's a powerful way to generate dynamic textures at run-time that are WebGL friendly and don't invoke expensive GPU uploads on each change.
