riocrokite Posted October 6, 2016 Share Posted October 6, 2016 on the unity / physx news front I caught this: unity 5.5 release target: nov 2016 - physx 3.3.3 now physx 3.3.3 might fix some of the inherent issues of wheels: Vehicles Fixed: Sticky tire friction was unreliable with more than one substep but is now fixed. This defect led to vehicles sliding down slopes where the sticky friction should have held firm. An error in the jounce speed calculation that led to lift force at high forward speeds has been fixed. This defect led to instabilities at high speed. Improved documentation for PxVehicleSuspsensionData::mSprungMass. We have to hope that in future ksp will upgrade to unity 5.5 and physx 3.3.3 source: https://unity3d.com/unity/roadmap http://physxinfo.com/files_new/PhysX_3-3-3_release_notes.html Link to comment Share on other sites More sharing options...

What makes you say that? All you know is that several employees left, probably when their contract allowed them to. Some of them were short-term contracters brought in for this release. In addition, the total development staff is still larger now than it was at the beginning of the year. Link to comment Share on other sites More sharing options...

It just doesn't behave the same as in the Unity editor... ARGH Hmm... that is a bit disheartening. Well, the semi- good news is that the force-based setup did work mostly. Could probably clean up most of its problems with a bit of careful coding / heuristics. The 'auto-strut' feature introduced with KSP 1.2 might also help -- IIRC it was added to 1.1 as a solution to jittering in the stock wheels/code, so may be exactly what we are looking for. Would still need to come up with a solution for bump-stop and sticky friction though; as I've not been able to find a solution to those from a force-based physics perspective. Will try and take some time this week/weekend to re-examine the force-based setup. You are also free to poke around with it if you want -- it is the master branch of the repository. Should already contain a compiled .dll and a ModuleManager patch to convert all of the stock wheels to the custom plugin (in the GameData directory in the repo; should be able to drop that in your KSP folder and be good to go). Testing might be as simple as that -- drop it into the 1.2 game, turn on the advanced-tweakables auto-strut, build and launch a craft, and play with the spring/damper sliders and see if/how it wigs out.

Defaulting to heaviest is fine, just don't lock them. I've been trying to figure out how to build complex suspension nonsense since 1.1, and I can't do that with the autostruts all locked to heaviest. Additionally, I've been thinking about a fully active suspension controller using a PID loop. The idea is that you have an electromagnet applying force as dictated by the computer. I imagine this should work in real life, but would it work ingame? The discrete timesteps tend to screw with things like this, as you're well aware, but maybe this option would be exempt.

A lot of potential. Just massive changes. I only hope we don't loose a lot of great talent to the horrer that is "Updating" And I wholeheartedly agree. All of you guys are very much appreciated.

riocrokite Posted October 13, 2016 Share Posted October 13, 2016 (edited) @lo-fi changing a topic for a moment, do you still have that particle setup from your bulldozer part? I was thinking of using it in my mobile screener unit animation (just for fun) where screened rocks are thrown outside via the conveyor belt Edited October 13, 2016 by riocrokite Link to comment Share on other sites More sharing options...
lo-fi Posted October 13, 2016 Author Share Posted October 13, 2016 Here you go: https://github.com/KerbalFoundries/KF_plugin/blob/Dev/KF_plugin/DozerBlade.cs Whether it works in later Unity is anyone's guess!

Shadowmage Posted October 15, 2016 Share Posted October 15, 2016 Recompiled the KSPWheel master branch against the KSP 1.2 libraries. Everything appears to be working about as it did before using the physics based suspension setup; which means it mostly does work. Patch is included for the stock wheels for testing purposes. For some reason though I can't find the auto-strut/advanced tweakables in my dev install, so have been unable to test if the auto-strut fixes the jittering. Hopefully will have a bit more time later today to work on that a bit/do more testing. Link to comment Share on other sites More sharing options...

I looked through your latest on Github and I *think* I grok where you're at... Though I'm not sure what this "bump stop/sticky friction" is... Jargon? Thanks for the offer Those are both terms that Lo-fi and I settled on so we knew what we were both talking about; you might not find them anywhere else. For us -- Bump Stop = anti-punchthrough, overcompression-prevention, basically keep the wheel above the ground even when it is overloaded or heading towards the surface at ludicrous speeds. Sticky friction = The ability for an object experiencing friction to 'stop' on an incline surface. Commonly referred to as 'static' friction (where dynamic friction is that of moving objects) in physics. On a bright note -- the testing of the physics based suspension went about as well as expected. It worked. Still had jitters at close-to-critical-damping. Largely usable though as soon as the bump-stop gets figured out. Sticky friction may be as simple as force re-positioning the transforms/part whenever undesired movement is detected. Jitters may be fixed through some careful code (examine if damper is rapidly going pos, neg, pos, neg, and apply some corrective / limiting measures / reduce damp or spring force when oscillating). Nearly finished with the 1.2 update push for my mod (few more things to fix, 6 or so more models to make), and then I should be able to dedicate quite a bit more time to finishing / fixing up the custom wheel solution. I really would like to see KF return for my next career playthrough Link to comment Share on other sites More sharing options...

Sadly it is more the latter than the former. Likely about a month of work left on my own mods stuff, plus need to finish the wheel implementation -and- get KF updated to use it.

Madrias Posted October 17, 2016 Share Posted October 17, 2016 Still, it's cool seeing some progress getting made, even if it's minimal. What matters most for Kerbal Foundries is having working wheel code. Anything after that is icing on the cake. Believe me, even I'm sitting here patiently waiting for the return of useful wheels, tracks, and other funny business. Sure, there's ideas I've scattered about in here, but one, they rely on having the wheel code working, and two, they're ideas without implementations, and without expectations on them. I'm comfortable hearing "Sorry, but that can't be done." It's why I throw ideas around, because I can't do them myself. Sure, I often config-bash stuff together and make a mess of things, but that's far from actual modding (though I will admit to feeling pretty-damn-smug when I took a wheel that used KSP 1.0.5's wheel colliders and forced it to use KF instead. Only took me three hours), and I can't do 3D stuff. But, thank you for continuing to work on this. I know many people in other modding communities who would give up if their mod got broken this badly by a game update. Link to comment Share on other sites More sharing options...

Keep in mind the guys are trying to get the physics to work with them at the moment; we'd be lucky to see a stock conversion by 1.2. Additionally, if you want these items to be present in the game, learn how to model and create one yourself! Grab yourself Blender or something and fab up a couple of models. The documentation is easy to find, and all the tools are free of cost. Additionally, some of your suggestions are outside the scope of Kerbal Foundries (by my interpretation). Prebuilt tank hulls and a specific tank are the realm of your own mod, based upon the groundwork of Kerbal Foundries. Just suggestions. i do agree that prebuilt things would need a different mod, but more types of tank suspension, such as treads you can wrap around parts, would be nice.
