Hi Gibbonuk, About your mail: we didn't find your previous email or web form question -_-. Can you tell us the date when you send your original message? We want to review deeper what could it happen. Did you email us to email@example.com. About your questions: - we have in the to-do list to develop a paragliding example, but we didn't make it yet, so we cannot tell yet properly. We can make a very very basic example for your testing purposes only. For the moment we suspect that additional code for simulate the non-rigidbody nature of the ropes and some additional code will be required to an complete example, but we do not know yet. Also, probably will be better to add more than one element for make a curved wing. - the lift is performed by the fluid simulation. Maybe you mean to simulate a ascendant current: you may only add upwards component to the wind speed vector. You can also simulate complex wind fields and patterns implementing a class that implements an interface included in the project and registering your class as the wind manager. About more advanced wind issues, we have also in the to-do list to make an glider example. - about the crash detection, it is done by high acceleration changes, so I guess that is perfect compatible with your case. If you land with a airplane on a rocky terrain a collision will trigger a crash if, for example, a gear crashes with a rock. It is in the to-do list to make things like that triggers a gear break apart. When that is done, if you land a 737 not too gently, the gear will be damaged or even break apart. - about when could be available a complete paraglider implementation, we do not know yet: we are still improving the avionics-autopilot controllers yet (we already included guns and rockets, and after that avionics-autopilot is the more requested feature, a lock for missiles and for complex AI, and also will enable to include more casual controls). Probably you are interested too in some of those enhancements. Aren't? If you can, please contact us directly by emailing us to firstname.lastname@example.org so we can talk about the basic paraglider example. Thanks!!! Kind Regards, Gargore.
