Experimental "solid" collision detection system for Orulex:
http://orbides.1gb.ru/orbf/collision_orulex_090128.php

ADD:
Version with tilting support.
http://orbides.1gb.ru/orbf/collision...90128-tilt.php

ADD2:
Version with UMMU support fixed and no tilting support.
http://orbides.1gb.ru/orbf/collision...90128-ummu.php

Usage:
Unpack, activate collision-core module.
Compatible with all 2008 and 2009 Orulex versions (0.9.0+).

The module is a meshland derivative made specifically for vessel-ground collision detection for Orulex.

It should provide solid collisions, stability of landed vessels at all time accelerations, state save/load support and minimal UMMU support.

It should also be stable - no jerking of the vessels, no jumping into space at warp speed, just hit&land.

If you're testing it, please write back if it is not so, under what conditions there are bugs, any suggestions you want to share, etc.

what's the UMMU support like ?
EDIT1: I have just downloaded it as soon as the Hight Map is down I will go in to orbiter to try it
EDIT2: is this like MeshLand ?
EDIT3: Its working fine

no impact on FPS but I have not landed properly yet but that's just me landing wrong

If you download the fix below (or above) - walking around the mesh with WASD keys (default ones fire RCS's which screws the motion).

It is MeshLand in essence, but instead of "one addon to rule them all" general purpose collision system it is a separateable special-case implementation of it.

I was thinking about making a sort of Universal Collisions SDK, something add-on developers can link to their DLL's to make their vessels landable Shukra-style, or collideable MeshLand centrifuge/hover carrier style.

That is the only way i found to make it work acceptably out of the Orbiter core.

I keep getting a CTD on load with the XR2 I will post my log soon let me just try again

I get it too, the crash happens with XR2 on the Moon in the XR2 vessel module, will investigate.
No crash on Mars.
What happens on your side?

**woo482** · 01-28-2009, 09:33 PM

It just CTD's with no errors

Um, planet? Scenario? Place and time? Conditions? Orulex version? Collision version?
Other sets of answers?

**woo482** · 01-28-2009, 09:40 PM

Latest Orulex on earth with the latest collision plugin from the link above.

**Artlav** · 01-28-2009, 09:45 PM

Ok, planet? Scenario? Place and time? Conditions?
Other sets of answers?
Any combination where it works?

**woo482** · 01-28-2009, 09:50 PM

I just told you all the stuff you wanted to know above and it was the 1st XR2 Scenario at the top of the folder.

More precisely, i was interested if other scenarios work or not and if there is a scenario that work. Like one on Olympus.

Anything in the Orbiter, XR2Ravenstar or Orulex logs?

**woo482** · 01-29-2009, 04:49 PM

ok tried it again and it still crashes and the Orulex and orbiter logs are not created
EDIT1:mars works but what Velocity should I land at ? I just Tried to land and I bounced up about 100 Meters

Was wondering if development on this is still continuing.

More or less. Orulex is long-obsolete and there is little interest in imperfect ground collision detection, but the system itself is still being developed along with NASSP and a few toys surface occasionally - look for Asteroids game for example.

dumbo2007 · 01-19-2010, 05:00 PM

I am trying to get an understanding of how you implemented this - for collision detection do you use bounding sphere detection....like if a body comes in a certain radius of a object you notify the body that it has collided ? Is there also a notification of the amount of reaction force to a colliding body ?
