How would you print things like the players position on the screen

I tried to use dbText but i soon found that you could not convert from int to char

How do you do it?

it was once said that a million monkeys at a million keyboards could re-produce the works of shakespear...
Now thanks to the internet we know that that is not true

You can use one of the following commands:

+ Code Snippet

char* dbStr (float fValue);
char* dbStr (int iValue);

Or you can try:

+ Code Snippet

dbText (10,10, dbStr(your_integer_goes_here));

Something i use to show me a variable i need to track is the function below. I guess you could show more than one if you get the variables you want into a char* to your string.
Iguess this is only for temporary use but ....

As long as you have a window it will show in top left of window bar.

:- Example showing width of bitmap I.D 2

dbSetWindowTitle(dbStr( dbBitmapWidth( 2 ) ));

Hope this is useful i have found that very useful.

Quote: "dbSetWindowTitle(dbStr( dbBitmapWidth( 2 ) ));"

This creates a memory leak. You have to deallocate memory of the string returned by dbStr using delete[] after you have finished using it. This goes for all DarkGDK returned strings.

Thanks for the info there, am i right in saying as long as the memory for that string is dellocated its ok to use that means of viewing variables ??

By creating the string
deallocating that string and
creating another etc etc ....

Sorry for seeming to be a bit of a dunce here !~@#$
but it would be nice info to know, as its a nice way for me to view variables easily.

Many thanks for that :- Regards Steve

Yes, the below code example shows how to use dbStr:

+ Code Snippet

// Dark GDK - The Game Creators - www.thegamecreators.com

// the wizard has created a very simple project that uses Dark GDK
// it contains the basic code for a GDK application

// whenever using Dark GDK you must ensure you include the header file
#include <DarkGDK.h>

// the main entry point for the application is this function
void DarkGDK ( void )
{
	int Integer = 5;

	char * String = dbStr(Integer);
	dbPrint(String);
	delete[] String;
	dbWaitKey();
	
	// return back to windows
	return;
}

If you are interested, here is a typical chunk of code doing what you require.
You should be able to adapt it to your needs.

void DisplayDebugInfo( void )
{
	// update DEBUG info to the screen
		char TempStr [ 128 ];
		sprintf_s( TempStr, 128, "FPS: %d", dbScreenFPS( ) );									dbText( 0,0,TempStr );
		sprintf_s( TempStr, 128, "World X Location: %f",Aircraft[iThisMachinePlayerID].fPosX );	dbText( 0,10,TempStr );
		sprintf_s( TempStr, 128, "World Z Location: %f",Aircraft[iThisMachinePlayerID].fPosZ );	dbText( 0,20,TempStr );
		sprintf_s( TempStr, 128, "Terrain height: %f", fCurrentTerrainHight );					dbText( 0,30,TempStr );
		sprintf_s( TempStr, 128, "Hight above Ground: %f", fCurrentAircraftGroundHeight );		dbText( 0,40,TempStr );
		sprintf_s( TempStr, 128, "Elevator: %d", Aircraft[iThisMachinePlayerID].iElevator );	dbText( 0,50,TempStr );
		sprintf_s( TempStr, 128, "Aileron: %d", Aircraft[iThisMachinePlayerID].iAileron );		dbText( 0,60,TempStr );
		sprintf_s( TempStr, 128, "Rudder: %d", Aircraft[iThisMachinePlayerID].iRudder );		dbText( 0,70,TempStr );
		sprintf_s( TempStr, 128, "Throttle: %d", Aircraft[iThisMachinePlayerID].iThrottle );	dbText( 0,80,TempStr );
		sprintf_s( TempStr, 128, "Guns: %d", Aircraft[iThisMachinePlayerID].iTriggerA );		dbText( 0,90,TempStr );
		sprintf_s( TempStr, 128, "Bullet Count: %d", iNextRealBullet );							dbText( 0,100,TempStr );
		sprintf_s( TempStr, 128, "cat: %d", cat );												dbText( 0,110,TempStr );
		sprintf_s( TempStr, 128, "Bullet X Location: %f",RealBullet[0].fPosX );					dbText( 0,120,TempStr );
		sprintf_s( TempStr, 128, "RotationY: %f", Aircraft[iThisMachinePlayerID].fRotY );		dbText( 0,140,TempStr );
}

+ Code Snippet

void DisplayDebugInfo( void )
{
	// update DEBUG info to the screen
		char TempStr [ 128 ];
		sprintf_s( TempStr, 128, "FPS: %d", dbScreenFPS( ) );									dbText( 0,0,TempStr );
		sprintf_s( TempStr, 128, "World X Location: %f",Aircraft[iThisMachinePlayerID].fPosX );	dbText( 0,10,TempStr );
		sprintf_s( TempStr, 128, "World Z Location: %f",Aircraft[iThisMachinePlayerID].fPosZ );	dbText( 0,20,TempStr );
		sprintf_s( TempStr, 128, "Terrain height: %f", fCurrentTerrainHight );					dbText( 0,30,TempStr );
		sprintf_s( TempStr, 128, "Hight above Ground: %f", fCurrentAircraftGroundHeight );		dbText( 0,40,TempStr );
		sprintf_s( TempStr, 128, "Elevator: %d", Aircraft[iThisMachinePlayerID].iElevator );	dbText( 0,50,TempStr );
		sprintf_s( TempStr, 128, "Aileron: %d", Aircraft[iThisMachinePlayerID].iAileron );		dbText( 0,60,TempStr );
		sprintf_s( TempStr, 128, "Rudder: %d", Aircraft[iThisMachinePlayerID].iRudder );		dbText( 0,70,TempStr );
		sprintf_s( TempStr, 128, "Throttle: %d", Aircraft[iThisMachinePlayerID].iThrottle );	dbText( 0,80,TempStr );
		sprintf_s( TempStr, 128, "Guns: %d", Aircraft[iThisMachinePlayerID].iTriggerA );		dbText( 0,90,TempStr );
		sprintf_s( TempStr, 128, "Bullet Count: %d", iNextRealBullet );							dbText( 0,100,TempStr );
		sprintf_s( TempStr, 128, "cat: %d", cat );												dbText( 0,110,TempStr );
		sprintf_s( TempStr, 128, "Bullet X Location: %f",RealBullet[0].fPosX );					dbText( 0,120,TempStr );
		sprintf_s( TempStr, 128, "RotationY: %f", Aircraft[iThisMachinePlayerID].fRotY );		dbText( 0,140,TempStr );
}

EDIT: you will have to do a copy and paste back into your VisualC++ IDE to get the correct formatting of the code back. It looks like this code windows can not handle code that long on a line.
