Atlas Editor
Using texture maps is practically a requirement in any professional game made with Phaser. In all previous version of Phaser Editor 2D we included the tools to create texture maps. However, a texture packer is not ready yet for this version of the IDE.
You can use third-party tools to create the texture maps:
Texture Packer is maybe the most popular tool in the Phaser community. It has an option to export to Phaser.
Download Phaser Editor v2 and use its Texture Packer Editor. It is a huge download.
