headache, help please! How to use PhsyxSdk 3.3.0 with VS2010

I’ve downloaded this : PhysX-3.3.0_PC_SDK_Core.
And I want to run a test code here:

#include <stdio.h>
#include <iostream>
#include <vector>

using namespace physx;
using namespace std;

static PxPhysics* gPhysicsSDK = NULL;

int startTime = 0, totalFrames = 0;
float fps = 0;
const int WINDOW_WIDTH = 800, WINDOW_HEIGHT = 600;

PxScene* gScene = NULL;
PxReal myTimestep = 1.0f/60.0f;

void StepPhysX()
{
	gScene->simulate(myTimestep);

	while(!gScene->fetchResults() )
	{
		// do something useful
	}
}

void InitializePhysX()
{
	PxFoundation* foundation = PxCreateFoundation(PX_PHYSICS_VERSION, gDefaultAllocatorCallback, gDefaultErrorCallback);

	gPhysicsSDK = PxCreatePhysics(PX_PHYSICS_VERSION, *foundation, PxTolerancesScale() );

	PxInitExtensions(*gPhysicsSDK);

	// Create the scene
	PxSceneDesc sceneDesc(gPhysicsSDK->getTolerancesScale());
	sceneDesc.gravity = PxVec3(0.0f, -9.8f, 0.0f);

	if(!sceneDesc.cpuDispatcher)
	{
		PxDefaultCpuDispatcher* mCpuDispatcher = PxDefaultCpuDispatcherCreate(1);
		sceneDesc.cpuDispatcher = mCpuDispatcher;
	}

	if(!sceneDesc.filterShader)
		sceneDesc.filterShader  = gDefaultFilterShader;

	gScene = gPhysicsSDK->createScene(sceneDesc);

}

void ShutdownPhysX()
{
	gScene->release();
	gPhysicsSDK->release();
}

void OnShutdown()
{
	ShutdownPhysX();
}

void OnRender()
{
	totalFrames++;
	int current = glutGet(GLUT_ELAPSED_TIME);
	if((current-startTime)>1000)
	{
		float elapsedTime = float(current-startTime);
		fps = ((totalFrames * 1000.0f)/ elapsedTime);
		startTime = current;
		totalFrames = 0;
	}

	if (gScene)
		StepPhysX();

	glClearColor(0.1, 0.1, 0.1, 1.0);
	glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);
	glLoadIdentity();

	glutSwapBuffers();

}

void OnIdle()
{
	glutPostRedisplay();
}

void main(int argc, char** argv)
{
	atexit(OnShutdown);
	glutInit(&argc, argv);

	glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH);
	glutInitWindowSize(WINDOW_WIDTH, WINDOW_HEIGHT);
	glutCreateWindow("Initialization");

	glutDisplayFunc(OnRender);
	glutIdleFunc(OnIdle);

	InitializePhysX();

	glEnable(GL_DEPTH_TEST);
	glDepthMask(GL_TRUE);
	glutMainLoop();
}

But errors show up:

And I set the directories like this:
External Media
But I make it a little difference : “win32” here is replaced by “win64”

please help me, thanks in advance！

Hi,

first, it would be incredible helpful when you translate the error message into english.
Second, when you are using PhysX 3.3, why are you using directories of PhysX 3.21 ?

Also, please try to link against the x86 libs when you try to compile a 32bit application.
Mixing 64bit libs with a 32bit compilation wont work, vice versa.

Other hint:
void StepPhysX() - there is no proper simulation step. Just dig in my profile, I wrote often
how to use a semifixed time step, and why you MUST use it if you really want to use PhysX for more than test applications.

Common hint:

Please recode your test application, your code shows that you doesnt have much skills in coding.

ak1 · January 14, 2014, 6:48am

I set every thing into “win32”, And I now can run the code normally.
It’s right I’am new in coding and everything.
Thanks for your helping and hints.

ScreenOfDeath · January 14, 2014, 9:26am

Hi,

you are welcome.
[When you are new in C++ coding, you should read tutorials, a book and something else to understand
what C++ is, how to deal corretly with pointers … .etc]

First you should read the PhysX Guide to understand how PhysX works.
Then you should look into the Snippets, after that you should look into the Sample folder.
Of course, trying to change some values / add some features in the Snippets would help to understand PhysX.

ak1 · January 14, 2014, 2:54pm

Yes,Your tips are incredible helpful!
I think following your steps to learn is not bad!

By the way, can the snippets be compiled directly?
I open ‘Snippets.sln’ in ‘vc9win32’ and compile it, but an messageBox shows up for me to choose an exe.
And I don’t know what should be chosen.

ScreenOfDeath · January 14, 2014, 6:21pm

Hi,

the snippets can be compiled directly. I dont know what messagebox you get, everything works fine on my laptop. Please explain it what the messagebox says or make a screenshot for us.

ak1 · January 15, 2014, 7:41am

sorry, I intended to make a screenshot, but it’s not English version.
The general idea of the message box is: choose an executable file for the debugging session.
hope you don’t mind：
External Media

ScreenOfDeath · January 15, 2014, 8:45am

Hi.

Woha. I cant read this language :D

I guess you try to attach the Debugger to an application.

I´m using Visual Studio 2013 and you can switch the debugger to be
“local Windows Debuggger” which is default, some other and
“Remote Windows Debugger” which could be set as your default by mistake.
(Or attach to a process)

Try to change it, maybe this is the problem.

ak1 · January 18, 2014, 5:50am

Now all seem fine.
Deeply Appreciate your help again.
