I have made a code for gravity and jumping physics. It isn't done, but i got a lot of errors that I don't know how to solve...

the code

#include "DarkGDK.h"
#include "SC_Collision.h"
#include "KeyID's.h"

void DarkGDK ( void )
{

dbSyncOn   ( );
	dbSyncRate ( 60 );
	SC_Start ();

//Load the map
	dbLoadObject ( "TunnelMap.x", 1 );
	SC_SetupObject ( 1, 1, 0 );

//Load You
	dbLoadObject ( "shotgun.x", 2 );
	SC_SetupObject ( 2, 2, 0 );
	dbPositionObject ( 2, 0.0f, 1.0f, 5.0f );

//Setup all the gravity and jumping things

int IJump=1;
	bool BJump = false;
	
	int IGravityPull=1;
	bool BGravity = false;

int IUpForce=1;
	bool BGround = false;

void Gravity();
	void WhileLoops();
	void Input();

while ( LoopGDK ( ) )
	{
		//Position You and Lock the Gun
		dbLockObjectOn ( 2 );
		
		//Gravity and Jumping
		Gravity();

dbSync ( );
	}
}
void Gravity()
{
	if (BGround == false )
	{
		BGravity = true;
	}
	if (BGround == true )
	{
		BGravity = false;
	}
	if (BJump == true )
	{
		BGravity = false;
	}
}

void Input()
{
	if (KeyState (SpaceKey == 1 )
	{
		if (BGravity == false )
		{
			BJump = true;
		}
	}
}

void WhileLoops()
{
	while ( BJump == true)
	{
		dbMoveCameraUp (0, IJump );
		IJump = IJump+1;
		if ( IJump == 10 ){
			BJump = false;
			BGravity = true;
			IJump = 1;
		}
	}
	while ( BGravity == true )
	{
		dbMoveCameraDown (0, IGravityPull );
		if ( BGround == true )
		{
			BGraviy = false;
		}
	}
}

I know how to solve some of the errors like the syntax ones, but the one where it says

c:\users\byron\documents\visual studio 2008\projects\global warfare\global warfare\main.cpp(80) : error C2065: 'BJump' : undeclared identifier

I don't know how to solve... Also the one that says

c:\users\byron\documents\visual studio 2008\projects\global warfare\global warfare\main.cpp(80) : warning C4805: '==' : unsafe mix of type ''unknown-type'' and type 'bool' in operation

Thanks.

Your functions cannot see variables you've declared outside of its scope that aren't in the global scope, i.e. every variable you get an error about, to fix this place 'bool BJump = false;' 'bool BGravity = false;' and all the others it complains about before your entry point function, in the global scope. These variables will now be visible anywhere in that file after its declaration.

So I put it before the void DarkGDK (void); ?

That would make sense..... Thanks.

Yep. And bear in mind that if you declare a variable with the same identifier inside another scope (function or block, for example) it will use that variable while executing in that scope instead, without affecting the one with global scope.

ok, I got it now. My problem is this- It won't load!!!! Nohing is wrong with it, the problem is that it is too much to procces. Is there a ways of shrincking the load time?

The code

#include "DarkGDK.h"
#include "SC_Collision.h"
#include "KeyID's.h"

//Setup all the gravity and jumping things

int IJump=1;
bool BJump = false;

int IGravityPull=1;
bool BGravity = false;

int IUpForce=1;
bool BGround = false;

void Gravity();
void WhileLoops();
void Input();
void Collision();
void OldPosition();

int Ox = dbCameraPositionX (0);
int Oy = dbCameraPositionY (0)+1;
int Oz = dbCameraPositionZ (0);

void DarkGDK ( void )
{

dbSyncOn   ( );
	dbSyncRate ( 60 );
	SC_Start ();

//Load the map
	dbLoadObject ( "TunnelMap.x", 1 );
	SC_SetupObject ( 1, 1, 0 );
	dbScaleObject ( 1, 100.0f, 100.0f, 100.0f );

//Load You
	dbLoadObject ( "shotgun.x", 2 );
	SC_SetupObject ( 2, 2, 0 );
	dbPositionObject ( 2, 0.0f, 1.0f, 0.5f );

while ( LoopGDK ( ) )
	{
		//Position You and Lock the Gun
		dbLockObjectOn ( 2 );

dbControlCameraUsingArrowKeys (0, 1.0f, 1.0f );
		
		//Gravity and Jumping
		Gravity();
		Input();
		WhileLoops();
		Collision();

dbSync ( );
	}
}
void Gravity()
{
}

void Input()
{
	if (dbKeyState (SpaceKey == 1) )
	{
		if (BGravity == false )
		{
			BJump = true;
		}
	}
}

void WhileLoops()
{
	while ( BJump == true)
	{
		dbMoveCameraUp (0, IJump );
		IJump = IJump+1;
		if ( IJump == 10 ){
			BJump = false;
			BGravity = true;
			IJump = 1;
		}
	}
	while ( BGravity == true )
	{
		dbMoveCameraDown (0, IGravityPull );
		if ( BGround == true )
		{
			BGravity = false;
		}
	}
	while ( BGround == true )
	{
		dbPositionCamera ( Ox, Oy, Oz );
		BGravity = false;
	}
}
void Collision()
{
	if (SC_GroupCollision ( 2, 1 ))
	{
		BGround = true;
	}
	SC_UpdateObject ( 2 );
}
