not really, i think its quite good, they just haven't put keywords and help in it, if you know c++ you could expand on it easily (i assume)

ODE is used because of licensing simplicity in FPSC. Newton is free, great, and has so many more features.


Come see the WIP!

It's very simple, and no, TGC's implementation is not very good. Get Dark Physics when it comes out, or use Newton. Newton is a lot more difficult(IMO) than ODE, but you'll get more realistic results.

If you decide to go for ODE anyway, I've made a keywords file. See the attached.

I haven't made any help files. And in fact, there are no help files, as TGC doesn't officially support ODE in DarkBASIC Pro.

Try searching the forums for ODE back in december i believe there was lots of ODE discussion...I believe it was the january newsletter that had the ode example.I will check for you.

[edit]
My bad it was all the way back in the october issue

[reedit]
just found a sight created by kenjar that lists the undocumented commands.

Ink all over the screen...and dang it! Signature still does not show.

hey i looked at the tut in the magazine seems pretty easy, one thing though, it doesnt explain what this means, it just tells you to do it:

ode set world step 0.05
ode set world erp (0.2)*2.5
ode set world cfm (10^-5)*2.5

i looked at the site you showed seems a good tut havent read it yet though ill give it a look thanks

im quite impressed thought, i may recode my game, how do i make the matrix the ground? so that the stff wont go through it
also how do you move stuff with it, the ode force thing makes it spin as it moves how do i stop that?

unfortunately ODE does not work with either matrixes or advanced terrain...just standard objects with no limbs. Also if there is too large of a gap between 3 vertices the face will not be seen by the engine.

As a side note...your objects center of balance is determined by the origin of the object...place the origin at very bottom and object will almost always land on it's base...put it at top and object will easily fall over and may even stand on head.

not sure about spin part never noticed i made a simple bowling program like 3 days after it was out.

You can use ode because it is great.
You can't use matrix and advanced terain with it but you can use complex direct x mesh (such as cartography shop world) !
Look at the ode thread by IanM in the dll section of the forum to get the latest version.
Hope that help...

LIT made some wonderful code to convert a matrix to an object... check it here -> http://forum.thegamecreators.com/?m=forum_view&t=58829&b=6
