PhysX (v2.7.3) & Irrlicht (v1.4)

[night_hawk]

Mine didn't work either? Mine is bound to work with the latest version (2.8.1).

[frostysnowman]

Your irrlicht & physX examples give me exceptions on startup as well

Unhandled exception at 0x004012fa in project.exe: 0xC0000005: Access violation reading location 0x00000000.

(from first example)

So do both of the precompiled examples crash on startup.

[night_hawk]

Oh, it's obvious then. You don't have the system software installed (or you have an older version of it...)

[frostysnowman]

Well, that sort of explains it

I had been able to run physX examples from the control panel, and run the precompiled example from here, so my mind never went to consider that it was a problem with the software runtime! However, I still cannot justify my stupidity.

I downloaded the new version and it seems that everything works now.

Thanks night_hawk, Problem solved.

Nvm.... Someone beat me to the punch.

Nice examples.

Could you please let me know if there are any documentation(guide, tutorials) about physX(not counting the samples that come with the SDK) cause I can´t find any theory about it, and I would like to study it.

Thanks very much

At

C:\Program Files\NVIDIA Corporation\NVIDIA PhysX SDK\v2.8.1\SDKs\Docs

there is a lot of documentation that is very helpful. Your filepath may be a little different depending on how you chose to install the sdk.

Thanks, those are a little introduction and the API.

I´ve found here: http://developer.nvidia.com/forums/inde ... topic=1640

that there were learning lessons, and they are remaking them, they were distibuted since 2.72, so u can get them here:
http://developer.nvidia.com/object/physx_downloads.html

If you want to check out the topics, check here:

Hope that it helps the ones in the same situation. Happy learning

hi,

I was able to successfully compile the code but when I click any mouse buttons the program crashes to desktop in the following line:
>> actor->addForce(forceVec);

I am using irrlicht 1.4 and Physx 2.81 with the latest system software drivers installed (8.04.25).

Any help would be appreciated.

Regards

I was going to make a post on this bug earlier....

There are two problems I am having.

1.) after a number of boxes are stacked on top of each other, certain boxes start to flicker and disappear. Some disappear completely and re-appear when struck by another box/sphere.

2.) The same error m506 says. I investigated into this, and with the doc example of a NxUserOutputStream implementation, it brought up this:



This was the code for the NxUserOutputStream implementation:

Code: Select all

class MyOutputStream : public NxUserOutputStream
{
        void reportError (NxErrorCode code, const char *message, const char* file, int line)
        {
            //this should be routed to the application
            //specific error handling. If this gets hit
            //then you are in most cases using the SDK
            //wrong and you need to debug your code!
            //however, code may  just be a warning or
            //information.
        
            if (code < NXE_DB_INFO)
            {
                MessageBox(NULL, message, "SDK Error", MB_OK)/*,
                exit(1)*/;
            }
        }
                
        NxAssertResponse reportAssertViolation (const char *message, const char *file,int line)
        {
            //this should not get hit by
            // a properly debugged SDK!
            assert(0);
            return NX_AR_CONTINUE;
        }
                
        void print (const char *message)
        {
            printf("SDK says: %s\n", message);
        }

} myOutputStream;

then when you call NxCreatePhysicsSDK...

Code: Select all

	MyOutputStream* ptr = &myOutputStream;
	gPhysicsSDK = NxCreatePhysicsSDK(NX_PHYSICS_SDK_VERSION, 0, ptr);

Any expert around on PhysX?

[monkeycracks]

I get random crashes, generally when I spawn things too quickly. Not sure if it's fixable at all but I figured I'd just let you know. Also, it seems to be mostly the cubes that make it crash.

[frostysnowman]

bump for importance

[acropole]

Physix is now the property of NVidia

[PhilippT]

And after spawn 100 or up spheres i got a crash with similar results >> actor->addForce(forceVec)

looks like the actors are out of predefined memory.

Has some fixes for a stable implementation?

the bug is caused when creating device with openGL try to change EDT_OPENGL into EDT_DIRECT3D9.
