Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

{{FGCquote
|1= HLA is really intended to operate at a much higher level of granularity and pass objects around a distributed simulation. The use-case I'm working on at the moment passes an AI instance as an object (with position, velocity, accelerations, model to be displayed). How a HLA Federate maps that data internally is an implementation decision. There shouldn't be any race conditions because no assumptions are made about how the data is used or mapped. At present, I'm not thinking that HLA will be used as a mechanism to provide a shared property tree across multiple Federates. I think that's the wrong way to use HLA. Instead you make explicit decisions about the data models you will communicate. The other reason HLA isn't a good choice is to do with simulation clocking. I'm still getting my head around this properly, but the overall model is one where the simulation clock is advanced, and the instance the updates and publishes changes to the RTI that will be picked up by other instances at the next clock advance.
