All Out provides 250,000+ assets for you to use freely in your games made on the platform!
At the bottom of the editor are two windows. The Asset Catalog and the Assets view
Adding Assets From the Asset Catalog
To add textures, sound effects, and animations to your project: search for what you're looking for, then, drag the asset into the scene view or into your assets list to download it to your project.
The assets pane on the right shows all the files and folders inside of your game's res directory. You can pull these assets directly into your scene by dragging them in, or reference them in your scripts.
Adding Assets From Your Local PC
You can add textures (.png), sound effects (.wav) or Spine Animations from your local computer to the res folder to use them in your game.
