Iam new to Unity.I have installed Unity Tool to build games today only with html5.
Can I build html5 apps using Unity?
If Yes How
How to begin with the sample codes etc.
I don’t think there is a way to build html 5 apps in unity. If html5 is what you want, this is a good place to start looking for an engine: http://html5gameengine.com/
Unity does not currently support HTML5 games.
If you want to make web browser games you can build for Unity WebPlayer, which is still far more powerful than HTML 5 games.
