Yay, another *cough* idiot over Newton forums. Given how even Julio replies sometimes, I think I'm not that surprised...

Just a question monster. How the heck do you bring up all these wrappers from apparently nowhere? I had a hard time setting newton working more or less OK directly. :shock: Awesome work.
Hope is the first step on the road to disappointment.

Stuff like that makes me wanna break out with a flame thrower. I sometimes wonder if they are only writing the engine to prove that they can - actually making an intuitive/friendly interface is as important as the library itself if you ask me - my time is valuable to me.

However, if Newton is usable from the PSCL then it's cool. PSCL is something to be excited about. I should hop over and give it a look. Until then, ODE time. I can't use Newton until Linux/OS X is supported anyway.

Walaber: Your walker demo looks awesome. You're the man! (I'm building an action game who's primary enemy are giant multi-legged walking machines.)

Walaber: Your walker demo looks awesome
thanks! that's an old demo, made when I was first learning Newton. with some of the new features, I think you could make much more articulated and impressive robots / walking machines if you wanted to...

Yeah, these are 4 and six legged creatures connected to cockpits via giraffe-type necks. The scale is pretty odd, the smallest are house sized with 4 legs and one head, the biggest has 6 legs, 2 heads, and is sky-scraper sized.

I'll post a screenshot as soon as it's all working, I stopped to look at PSCL, but the ODE plugin isn't there yet - I'll have to just use it directly for now.

By the way - my game is supposed to be playable by summer - I'll post here more often as that time approaches.

Dunno what I missed on the Newton boards. Sounds like there was some conflict.

Anyway, I see a new version is available as of yesterday.

Are there any wrappers that can be shared yet? I see a few people working on Newton but not sure of the relative progress.

Depends on your timeframe, IMO.

Monster, Robomanic, Walaber, et. al. wrappers all seem to have wonderful things going, however they are a bit limiting. However there is a learning curve that's subject to change at any time. And personally, I'm just a fan of community code - it's too much to expect one person to be able to (continiously) maintain support of something that was developed for their own use.

I think the ODFRocket/PSCL suggestion is the best thing to come along in years. Then you can easily use the "best" physics engine for the job at hand - without having to worry about (re)implementation. It would be to Newton's *great* advantage to support the development of the Newton ODF plugin as much as possible - it'll help alleviate the very pains that monster mentioned. Additionally, it'll (or, rather, it already) do things that these custom wrappers will (probably) never come close to.

However, the ODE plugin is what I'm waiting for :-). Off the bat, is ODFRocket cross platform?

(Note that I mean this in the most objective tone possible.)

http://sourceforge.net/projects/odepscl/
the ode openphysics bindings are a bit out of date

the next release of rocket is planned to be more, if not actually, cross-platform

Thanks Monster I will take a look. I had used ODE directly and Tokamak with Ogretok. To be honest I get the feeling that Newton is the way to go but we will see.

Thanks for the link.

I've also got monster's wrapper, for which I have added support for the vehicle joint if you need it.

I haven't released it yet because I am working on a sister library for the vehicle joint that allows XML loading of engine, transmission, wheels etc.
