IrrPhysx 0.2 - Nvidia Physx 2.8.1 wrapper

Make sure you are running msvc 2008 or recompile IrrPhysX with your compiler.

The heightfield example won't run for me. Does that mean it probably won't in my game? Though you did seem to fix the cloth example crashing.

That's weird modelerman... but similar to the apparent problem with the game example for a lot of people... when the heightmap was removed it worked fine.. there must be something wrong with the heightmap code on certain systems... can't think what though... :s

I also got linker errors trying to set up IrrPhysx. Do I need to set up the NVidia PhysX SDK?

Of course, you need to download 2.8.1 and also install the Physx system software. This is all explained in the first post with handy links provided!

Is their a way to create a box collision object from an Irrlicht scene node?
Create box object doesn't seem to let you pass a scene node.

uh.... just pass in the dimensions of the scenenode's bounding box.

Come on 3dmodman... look at the examples, it's all shown for you there, i thought you had learned this by now!

Whoops

. I've never used a physics engine that actually worked before. I looked throught the API and kinda got the way it worked mixed up, I'll loo at the examples for everything I can.

I can't find anything like an addForce function in the docs for IrrPhysx.
Is their a way to do this?

I did look at putting in an addForce function but wasn't happy with the results of it..

Something you may be able to use is setLinearVelocity which will make the object move in the specified direction.

You can always cast an IPhysXObject to a CPhysXObject and gain access to the PhysX actor, thus using the physics API to manipulate the object, instead of relying on the wrapper to do it. However, before you do that, I'd suggest you keep the PhysX API doc in hand and take a look at the internals of the wrapper to make sure you don't step on its toes.

What I want to do is make my character jump with an add force command. But I think the solution Dark_Kilauea had is somewhat complicated for me.

JP · Post by JP » Mon Feb 02, 2009 8:39 am

Dark's suggestion isn't particularly hard... you'll just probably need to add some extra Physx includes and such to your code so that it'll compile and then you'll have to look at the Physx documentation for how to apply forces to Physx Actors.

Incidentally I'm working on getting a Irrlicht 1.5 compatible IrrPhysx released... getting some weird crashes in the CRT with nvoglnt.dll in a lot of cases though which is rather weird... might need to fiddle my drivers a bit...

The IrrPhys was really wonderful as to me.

But when downloading the IrrPhys SDK, I failed.

The package always lost some files.

Can someone who would like to share the SDK with me?

whugang@gmail.com Thanks.

ummm

ohhh

Box object

....

force?

how though?

I could not even compiled
