Create an Endless Scroller Game With Unity WebGL and Play in Desktop Browser

Depending on your project size and platform, it can be challenging to update all your assets smoothly! echo3D has made it easy to do this by simply using an API key. Assets are stored on the echo3D cloud and called at runtime so your experience runs smoothly and faster, every time and everywhere. In this tutorial, you will add the background during gameplay through the echo3D cloud to show you a very simple example of how you can do this across all platforms, including Simmer.io.
