I just can't find the problem here. No errors, it just not do what it's supposed to do D:

+ Code Snippet

	if ( dbUpKey ( ) )
	{
		if ( dbCameraAngleY() == 0 )
			dbPositionCamera ( dbCameraPositionX(), dbCameraPositionY(), dbCameraPositionZ() + 1 );

		if ( dbCameraAngleY() == 90 )
			dbPositionCamera ( dbCameraPositionX() + 1, dbCameraPositionY(), dbCameraPositionZ()  );

		if ( dbCameraAngleY() < 90 && dbCameraAngleY() > 0 )
		{
			100 - dbCameraAngleX() == ninegraderY;
			100 - ninegraderY == ninegraderX;
			dbPositionCamera ( dbCameraPositionX() - ninegraderX, dbCameraPositionY(), dbCameraPositionZ() + ninegraderY );
		}
	}

Thanks

Are these supposed to be as you've written them?

+ Code Snippet

			100 - dbCameraAngleX() == ninegraderY;
			100 - ninegraderY == ninegraderX;

Shouldn't they be like this?

+ Code Snippet

			ninegraderY = 100 - dbCameraAngleX();
			ninegraderX = 100 - ninegraderY;

I'm not sure what that will do to your code, or what you were aiming for - you didn't tell us.

Ya, using '==' symobolizes testing for truth in the statement. You use them mainly in 'if' statements, 'while' loops, etc. You use '=' to assign values.

Using:

+ Code Snippet

			100 - dbCameraAngleX() == ninegraderY;
			100 - ninegraderY == ninegraderX;

...doesn't really make much sense, unless there's something you're not telling us about your code.

Here is the full code:

#include "DarkGDK.h"

int ninegraderY;
int ninegraderX;

void Game();
void Gravity();
void Movement();

void DarkGDK ( void )
{
	dbSyncOn   ( );
	dbSyncRate ( 100 );

dbMakeObjectBox ( 1, 100, 0, 100 );
	dbPositionObject ( 1, 0, -21, 0 );
	dbColorObject ( 1, dbRgb ( 0, 50, 0 ) );

dbMakeObjectCube ( 2, 10 );
	dbPositionObject ( 2, 0, -15, 10 );
	dbColorObject ( 2, dbRgb ( 255, 255, 255 ) );

dbPositionCamera ( 0, 10, - 10 );

while ( LoopGDK ( ) )
	{
		Game();

dbSync ( );
	}
	return;
}

void Game( void )
{

Gravity();
	Movement();

}

void Gravity( void )
{

if ( dbCameraPositionY() > - 10 )
		dbPositionCamera ( dbCameraPositionX(), dbCameraPositionY() - 1 , dbCameraPositionZ() );

if ( dbCameraPositionY() < - 10 )
		dbPositionCamera ( dbCameraPositionX(), dbCameraPositionY() + 1, dbCameraPositionZ() );

}

void Movement( void )
{

if ( dbLeftKey ( ) )	
		dbYRotateCamera ( dbCameraAngleY() - 2);

if ( dbRightKey ( ) )	
		dbYRotateCamera ( dbCameraAngleY() + 2);

if ( dbUpKey ( ) )
	{
		if ( dbCameraAngleY() == 0 )
			dbPositionCamera ( dbCameraPositionX(), dbCameraPositionY(), dbCameraPositionZ() + 1 );

if ( dbCameraAngleY() == 90 )
			dbPositionCamera ( dbCameraPositionX() + 1, dbCameraPositionY(), dbCameraPositionZ()  );

if ( dbCameraAngleY() < 90 & dbCameraAngleY() > 0 )
		{
			ninegraderY = 10 - ( dbCameraAngleX() / 10 );
			ninegraderX = 10 - ninegraderY;
			dbPositionCamera ( dbCameraPositionX() - ninegraderX, dbCameraPositionY(), dbCameraPositionZ() + ninegraderY );
		}
	}

}

+ Code Snippet

#include "DarkGDK.h"

int ninegraderY;
int ninegraderX;

void Game();
void Gravity();
void Movement();

void DarkGDK ( void )
{
	dbSyncOn   ( );
	dbSyncRate ( 100 );

	dbMakeObjectBox ( 1, 100, 0, 100 );
	dbPositionObject ( 1, 0, -21, 0 );

	dbColorObject ( 2, dbRgb ( 255, 255, 255 ) );

	dbPositionCamera ( 0, 10, - 10 );

	while ( LoopGDK ( ) )
	{
		Game();

		dbSync ( );
	}
	return;
}

void Game( void )
{

	Gravity();
	Movement();

}

void Gravity( void )
{

	if ( dbCameraPositionY() > - 10 )
		dbPositionCamera ( dbCameraPositionX(), dbCameraPositionY() - 1 , dbCameraPositionZ() );

	if ( dbCameraPositionY() < - 10 )
		dbPositionCamera ( dbCameraPositionX(), dbCameraPositionY() + 1, dbCameraPositionZ() );

}

void Movement( void )
{

	if ( dbLeftKey ( ) )	
		dbYRotateCamera ( dbCameraAngleY() - 2);

	if ( dbRightKey ( ) )	
		dbYRotateCamera ( dbCameraAngleY() + 2);

	if ( dbUpKey ( ) )
	{
		if ( dbCameraAngleY() == 0 )
			dbPositionCamera ( dbCameraPositionX(), dbCameraPositionY(), dbCameraPositionZ() + 1 );

		if ( dbCameraAngleY() == 90 )
			dbPositionCamera ( dbCameraPositionX() + 1, dbCameraPositionY(), dbCameraPositionZ()  );

		if ( dbCameraAngleY() < 90 & dbCameraAngleY() > 0 )
		{
			ninegraderY = 10 - ( dbCameraAngleX() / 10 );
			ninegraderX = 10 - ninegraderY;
			dbPositionCamera ( dbCameraPositionX() - ninegraderX, dbCameraPositionY(), dbCameraPositionZ() + ninegraderY );
		}
	}

}

What I want to do with the funktion:

+ Code Snippet

	if ( dbUpKey ( ) )
	{
		if ( dbCameraAngleY() == 0 )
			dbPositionCamera ( dbCameraPositionX(), dbCameraPositionY(), dbCameraPositionZ() + 1 );

		if ( dbCameraAngleY() == 90 )
			dbPositionCamera ( dbCameraPositionX() + 1, dbCameraPositionY(), dbCameraPositionZ()  );

		if ( dbCameraAngleY() < 90 && dbCameraAngleY() > 0 )
		{
			100 - dbCameraAngleX() == ninegraderY;
			100 - ninegraderY == ninegraderX;
			dbPositionCamera ( dbCameraPositionX() - ninegraderX, dbCameraPositionY(), dbCameraPositionZ() + ninegraderY );
		}
	}

Is just a other way, than just using dbMoveCamera ( laggy ). I wanted the camera only to move at the X- and Z-Position.

Sorry for my bad english.

But thanks for the help anyway
