I updated my servo example based on the Transaction draft, and this might actually work. I replaced External with Interface as suggested, but I also add event’s to variables that can be caught with On. Once we receive and Update event we need to do a transacion ourselves since we will update the servo entry.
What I am most happy with here is less code + that we can’t go wrong since the interface keyword will force the use of transactions. I am not sure how I will get the Assembler to keep track of what entries we actually do transactions on with arrays involved so I need to work on that. I like the idea of having events on variables and not only on objects. It makes sense in this case since we need an event on one channel to operate another.
I am reaching a point where I can only do so much without a working VM and Assembler! It basically gets harder to see the missing details or flaws in the drafts.
