Took a look around their dev docs and I can see Playcanvas having no issue to work on that platform.
Each Playcanvas build is a fully compliant HTML/CSS/JS application.
Now each Koji app is a “remix” of an existing app, so you can search and find a boilerplate HTML/JS app and adjust it to host the Playcanvas build. I imagine this would require some work to get it right but eventually you will get there.
It looks like it is more like CodePen rather than a place to host games. The output of the playcanvas editor kind of goes against the idea of what WithKoji is for.
Using the PlayCanvas engine only is more appropriate for use on the WithKoji platform.
I’m creating a game template for Koji to use(which is what my racing game is for). They said I can use any game engine as long as they can remix the project later on from the Koji editor.
I contacted the admin on Koji. He said that we can remix a project called webpack for what we need. Once I download the project, and upload it to the Koji editor, all the assets will show up in the editor. They can be replaced inside of the editor after this.
