My understanding is that Coop is blocked by Laminar Research.
- Laminar changed how avionics are rendered.
- Laminar updated the default aircraft to use their new avionics.
- We as developers are waiting on the SDK and tools to be expanded in many ways to allow us access to all XP12 can do.
I've attached a Screenshot from the XP-Developer Slack chat where Ben Supnik explains some of the logic behind current choices.
Further in the thread Ben S. explains that Laminar is looking to expand the "click" processing to better suit things like; real touch screens, VR, VR Gloves, and boring old mouse clicks.
The obvious solution seems to be to provide patched versions of the default aircraft files that can hook the the mouse clicks but I don't think it's possible at this time with the way XP12 has changed.
The thread that screenshot is from was quite long and several other developers(including Laminar for their own mobile titles) are wanting better functionality for these items so hopefully it's high on Laminars priority list.
