I am trying to access the Kongregate shared content API but this is only available to Flash AS3. So would it be possible to host the game elsewhere alongside a tiny flash window (1x1px) and then have them communicate via server side Javascript (I have only used Unityscript before). Does anyone think this would be possible without too much trouble? Thanks in advance, Will.
Well, i don't know anything about Kongregate but it should be possible, like you mentioned: run a small flash window and communicate via "client side javascript". You never have javascript or flash serversided. Flash is only executed on the client inside the browser (you will need the flashplayer like you need the Unity webplayer for Unity.
In Flash AS3 use the "ExternalInterface" to call a javascript function inside your webpage and offer the webpage a "channel" back into flash. The Unity docs have an great article about Unity webplayer and brownser communication.
That should be all you need.
So communication will be like:
Flash–>webpage–>unity
and
unity–>webpage–>flash
