Hello Everybody. I have some problem. When I'm using the dbLoadDLL and dbCallDLL function in the code, the compiler was returned to me an error.

Code:

+ Code Snippet

	dbLoadDLL((DWORD) "darkphysics.dll",1);
	dbCallDLL(1,(DWORD) "start");

Output from vc++:

Can You help me?

The major problem is that you called "dbLoadDLL" and "dbCallDLL" with a wrong parameter type!

For example the function "dbLoadDLL" needs two parameters: one is a string <char*> and the other is an <int>, like this:

void dbLoadDLL( char* Dll_File, int Dll_ID );

The mistake is that you called it with an <unsigned long> which is defined as <DWORD> and an <int>, ...and the only problem is that you must to make the call without (DWORD)...

like here:

dbLoadDLL( "darkphysics.dll", 1 );
dbCallDLL( 1, "start" );

I hope this was helpful, I think!
Cheers!

First say to yourself what you would be; and then do what you have to do.

Why are you even trying to load DarkPhysics that way?

If you have the headers - you just:

+ Code Snippet

//----------------------------------------------------------------------------
JGC_DARKPHYSICS::JGC_DARKPHYSICS(int p_HeartBeatInMilliSec){
//----------------------------------------------------------------------------
  // 0=Software, 0 = RigidBody Scene, 1=allow Multithreading.
  #ifdef USE_DARKPHYSICS
    dbPhyStart(dbPhysX(),0,1);// Start Physics engine
    //dbPhyUpdate(0);
    dbPhySetAutoFixedTiming();//Not Sure I should have this with a heart beat thingy
  #endif
  this->HeartBeatTimer = new JGC_TIMER();
  this->HeartBeatTimer->Set(
    this->pvt_iHeartBeat=p_HeartBeatInMilliSec,
    JGC::Clock->Time_New
  );
};
//----------------------------------------------------------------------------
