The Garry's Mod VPhysics Replacement Project

[Grayman]

Woo, fixed the vehicles restarting their sounds.

Turns out there was an issue with the physics KeyParser::ParseCustom dealing with the fact that I was recursing before calling ParseKeyValue.
I hope this is the last fix dealing with the keyparser for now!

[Grayman]

Looks like pimpedupride is going to come in an even more pimped up version in vphysics!

P.S: I've updated all of the old videos in the OP with newer high quality ones.

[Skyfire12]

Hey Grayman, wish I'd have more time to test the physics out. 3 weeks of school left for me!

It's looking good though :D

[HarryTheNarwhal]

Hey Grayman, is the body portion of it fixed? On servers, the vphysics cause crashes and I want to know if this is useful for Gmod MP servers yet? I noticed it says it doesn't require clientside.

I'm guessing you're referring to the infamous ragdoll crash in valve's vphysics.
Mine doesn't crash, but ragdolls aren't solidly implemented (they act really weird). You can spawn some ragdolls and see how they behave in my vphysics.

Also, I should mention: many maps weren't built to handle the overly rigid constraints that my vphysics has, so that might be a HUGE source of lag because they'll start spazzing out.

[HarryTheNarwhal]

Is this usable on game servers to assist with the crashes or would it not help at all? I run TTT and hope this might help.

Expand upon this further please.

Why would a map have constraints?

Why would said constraints start spazzing out?

Don't the rigid constraints mean it won't spaz out?

Some maps have objects constrained to static objects (for example the physics puzzles in HL2).
They spaz out because the level designers placed the objects in a way where they penetrate with the world. In IVP this wasn't a problem because constraints are sort of weak and can tolerate invalid states, but bullet's constraints are pretty solid.
So, every frame the constraint tries to move the objects into a valid position (which happens to be in the world), and the contact constraints will try to separate the objects.

See the reply right above your post.

[HarryTheNarwhal]

Sorry, I'm alittle stupid, anyway, Darn it, sad to hear that. Really needing a fix for that stupid crash issue.

[Grayman]

I figure an update would be good: I've fixed the positions of the ragdoll constraints so the bones rotate around the correct points, but the 6 dof constraint internally uses Euler angles to solve error on all axes.
The fun part about that last fact is if the y-axis is the only free axis and the offset on it is +/-90 degrees, the whole constraint freaks out. I'm gonna have fun fixing this one (and this fix may benefit other people that use bullet as well).

Euler angles: The worst of them all.

[thelastpenguin]

I'm wondering if there is any news as to how stable is this at the moment. Particularly I'm interested as to it's potential for use in, perhaps not build servers yet, but physics based minigames to allow them to support higher prop counts / player limits (I think...) ?

Like I said, it's pretty stable at the moment (almost no crashes).

Whoops, just committed a fix for that. I don't regularly build for linux so that slipped past me.

[BomBom]

I managed to get the linux version compiling but there were errors.
Also haven't managed to get it loading at all, seems to stop the server from booting.

Is there a reason for gmod to have 2 vphysics files?
There is vphysics.so and vphysics_srv.so...

Other source games like TF2, DODS, L4D, L4D2, Portal, Portal2, CSS, CSGO only seem to have vphysics.so, any ideas?[/QUOTE]

It's most likely because server owners were asking for Garry to compile with old glibc so it wouldn't break on old operating systems. the vphysics.so is compiled with newer glibc (maybe newer gcc too) and can be removed or replaced with vphysics_srv.so (at least theoretically). It might be that the non _srv versions are meant for gmod client but accidentally slipped to srcds downloads too.

Managed to compile and it doesn't crash at least immediately: [url]http://g3.metastruct.org:20080/vphysics_srv.so[/url]

Haha, a single combine ball was too much for it. 5 fps.

Tried both your compile and mine, still not managed to get this working on my ubuntu or debian servers.

Huh, weird. VPhysics has OK performance for me on linux (I haven't ran any benchmarks but it certainly isn't that slow).

Sorry, I don't know what's wrong. I'm not too terribly good at using linux.
