+--- Thread: [SUGGESTION] In game physics (/showthread.php?tid=862)
In game physics - poVoq - 08-22-2010
What ever happened to the ODE implementation that was already done for Nexuiz as a test? Would be definitely cool to have
Otherwise... have you though about implementing the ragdoll hack found in Cube2 (not full physics), or had a look at the Bullet physics implementation found in the Quake2 derived Ya3Dag ( http://www.ya3dag.de/ ).
Not sure how easy it is to port something from Quake2 to Quake1/Darkplaces. I am assuming though that it is easier than a full reimplementation from scratch.

If ragdoll physics are implemented (as a part of ODE?) we could use those instead of death animations, which would make a smoother experience (and less effort for modelers).
RE: In game physics - DiaboliK - 08-22-2010
ODE is simply too slow as far as I know.
As for ragdoll animations, they are theoretically possible with csqc players with bone control in code.
RE: In game physics - poVoq - 08-23-2010
If you think ODE is slow, I guess you will not like a csqc implementation either since it is a interpreted language (10-20 slower than native C). Besides the quakec code doing this I have seen some time ago was horribly glitchy.
I think Bullet is a bit faster then ODE though, so that might be an good alternative.
RE: In game physics - divVerent - 08-23-2010
The problem of ODE is not being generally slow, but being slow in some "evil" cases (e.g. an object wedged between two other objects). Even when using ODE for gibs, these situations happen a lot.
RE: In game physics - poVoq - 08-23-2010
The way the gibs fly currently is already quite neat, so no real need for change there
But why not limit the number of things ODE is used for? If for example only ragdolls and hmm maybe vehicle physics are done by it, it should probably eliminate most of the "evil" cases.
But IMHO a full physics integration is not really needed for a game like Xonotic anyways, so maybe having a look at the Cube2 ragdoll hack would be the better option?
Btw OT: Is the animation blending implemented in DP now?
RE: In game physics - rainerzufalldererste - 08-23-2010
I like the idea to have ragdoll-physics in xonotic!
But only in the kills without gibs! (uzi, shotgun, rifle, nex/xon, laser, crylink, HLAC)
RE: In game physics - Hypnosekröte - 08-24-2010
Is there no way to improve the performence ?
ode would be so amazing 8D
RE: In game physics - Mr. Bougo - 08-24-2010
Not really, it's a huge jump forward in terms of calculations, to have something that doesn't look bad.

it's in QuakeC and tested in DP. Still not fully featured, but if ported to client side QC it could be used for cool effects.

Twig is slower than ODE afaik, and the project is idle now.

Necromancing
Now that client-side QC animations blending at bone level is implemented and working, it might be worth looking into that TWIG lib again for ragdoll death-animation support

It's still slow as hell though.
RE: In game physics - poVoq - 04-04-2013
If it was just used for Ragdolls it would probably be not so bad... besides it could be an option in the menu for faster PCs
P.S.: here is a working download link to the lib:

RE: In game physics - Mr. Bougo - 04-04-2013
Honestly, I don't know. As soon as you put constraints on the limbs, everything becomes complicated to compute.
