For anyone else that comes across this looking for ways to extend arcade with their own special features / controls / simulators, a lot can be done in the same way as this one using the simmessages – this is where the makecode project says to listen for the messages / how to handle them:

> <https://github.com/eanders-MS/arcade-webcam/blob/e9fb61f120fb1d251ed445f7e55cdeb10299a9c8/main.ts#L30>

and this is where the outer website sends the messages to the frame:

> <https://github.com/eanders-MS/arcade-webcam/blob/e9fb61f120fb1d251ed445f7e55cdeb10299a9c8/assets/js/custom.js#L105>

and here’s where all the stuff related to this is defined in common packages:

> <https://github.com/microsoft/pxt-common-packages/blob/master/libs/base/sim/controlmessage.ts#L3>

Again, worth noting this is simulator only, and only works when hosted from your own website – but it’s fairly easy to make your own site if you want to play around with this thanks to the github integration creating a github pages page like Eric’s automatically 🙂 ~
