OPAL is a nice, high level physics layer on various physics libraries (currently only ODE, however its abstraction is very clean)
anyone whos used commercial libraries like Havok will really like this one.
ODE isnt the best physics library (try stacking alot of boxes!), but its BSD based so its totally free to anyone to use it.
ill add these (and my others) to AUR when i get the time
Note:
the library for tinyxml is currently made in the OPAL pkgbuild.. which is very bad.. but tiny doesnt have its own make files to generate a static library, only a test binary..
so for now itll have to do
here are the pkgbuilds

I get that ld-error on a number of packages for the i586 port. I still have no idea why tho.
A bus station is where a bus stops.
A train station is where a train stops.
On my desk I have a workstation.

the $startdir/src/opal-0.3.0-/src/SConscript file has a block of code like this
# Add in XML source if desired
if env['XML']:
if env['debug'] == True:
env.Append(LIBS = ['tinyxmld'])
else:
env.Append(LIBS = ['tinyxml'])
if i comment it out, opal compiles, atleast i think it does.. it was pretty quick.. heh.. so i _hope_ its right
now i just have to get my head around `sed' so i can put it in the pkgbuild.. eugh..

for deleting several lines like that, there is a nice way to do it with vim in the pkgbuild, Check out the rox pkgbuild, i think thats where i saw it. unless its easier with sed..

well, it 's easy to sed /14,25d/ , but, out of curiosity, what comes to mind
(in sed syntax) when asking for:
- find a match
- delete specified number of subsequent lines
i don't find an easy sed command for that.

thanks for the suggestion guys, it made me go and search for a sed tute and i found one that was _reasonably_ well explained..
ive updated the packages above
