Mission creation resources v1.0
These are some files to help you with mission creation. For a general guide on mission creation you can use this FSDeveloper wiki page.
The SimpleMission ZIP is a sample project for creating missions, like the ones you find in the SDK. This project is a good starting place for creating any mission, except for Bushtrips or LandingChallenges (for those you are better of just using BushMissionGen or BushTripInjector).
