[worldKit-dev] Controlling annotation visibility based on zoomlevel

[Mikel Maron]

That's excellent. I've wanted to get worldKit compiled with MTASC, and integrated with the whole osflash toolset. There's nothing stopping this from going forward, someone just needs to put it together, and I haven't had a chance to get dirty with it.

Thanks, Mikel.

The first approach would probably be a good start for me. I may have some time in the next couple weeks to work on this.

As a first step, I'd like to get setup to build the source. Is MTASC an option?
