Ageia PhysX problem

needforhint · Post by **needforhint** » Sun Mar 09, 2008 7:17 pm

hello,
I have a problem integrating PhysX to irrlicht, but the heart of the probelm is in PhysX not irrlicht. When I call NxActor::setGlobalPose() function with a correct matrix parameter and then afterwards call NxActor::getGlobalPose() function I don't receive the matrix I was setting with setGlobalPose(). So how to set actor's matricies?

Would say that's not a problem for the Irrlicht forum. But just to let you know, I'm planning on using PhysX in my project, and Praetor is working on creating a new Wrapper for Irrlicht.

there are no forums about Ageia PhysX you see

Yeah. That is partly the right forum, but the wrong section. It is a good forum to ask on though because numerous people on here have worked with PhysX programming.

One thing you could do so that people can help you with your problem easier, is to post your code. I am almost certain that those setters and getters aren't the problem, but it is instead the code around it.

when you call setGlobalPose() it only tells the simulation where to move the actor, it doesn't actually change the matrix. you won't get the matrix back until after you've called simulate and GetPhysicsResults()(maybe).

you might get weird results if you change the pose of a dynamic actor so you might want to use a kinematic actor(actor->raiseBodyFlag(NX_BF_KINEMATIC)) and use moveGlobalPose()

btw there is a forum on the ageia developer website, but its not very active...

Yeah, I'm working on a wrapper for irrlicht and PhysX, I'll post in the project announcement section when I have a version ready (not quite sure when, I'm gonna be busy over the next while, but I hope to make a good amount of progress this weekend). It'll be released under the same license as irrlicht (zlib).

Regarding the globalPose stuff my guess would be the same as gheft's, I think Ageia has to update before the getGlobalPose() function will return the correct value.

Huh? Good or bad karma?

Good, of course. And while we're on the subject...

Praetor.Karma++();

Ah, okay. Disregard my message to you then, I interpreted it wrong. Sorry.
