I started playing around with webOS development, so I have no real experience with it.
I created a basic web app from template and included pixi.js library to display a simple sprite on screen.
On both simulator 6 and 22 the app works just fine, but when I install it on TV, the sprite doesn’t appear.
The webOS TV uses different web engines depending on the webOS version. See Web Engine.
So please check the scope of support for the web API that you want to use based on the web engine information first. Thank you.
I have almost no experience with webOS or even web development, but I thought that the whole point of the simulator was to be able to develop your app locally and then everything should work fine on TV itself.
