source for built-in plugins?

the plugin tutorial was helpful, but i still have alot of questions. is it possible to view source for phys/keybrd/bones(any or all) ? it would be very helpful.

There are currently three plugins on the CVS which you can find here.

We're planning on adding more, but frankly a lot of the plugins right now are a mess, and it would be counterintuitive to put their sources up. A lot of things do things not as best as they could so they're not an ideal sourcecode to learn anything from...

In other words, they need to be re-written?

They need to be transferred to the new SDK format. Most of them use the old style, which whilst working fine, is rather a mess (as it evolved).

thank you

ok, well, rather than starting another thread for this, is it possible to create behaviors that have dependencies on other behaviors? for instance, could I make a plugin that requires the object to also have platform behavior applied and uses actions and accesses properties from the platform behavior as it applies to that object?

Yes, but you would need to modify both. If you want to add functionality to the platform behavior, you should suggest your changes or offer to directly modify the platform behavior. There is no need to fragment functionality across behaviors.
