alright, i found out how to get the object to move with arrow keys with:

+ Code Snippet

if ( dbUpKey() == 1 ) {
         dbMoveObject( 1, 1 );
      }
      if ( dbDownKey() == 1 ) {
         dbMoveObject( 1, -1 );
      }
      if ( dbLeftKey() == 1 ) {
         dbMoveObjectLeft( 1, 1 );
      }
      if ( dbRightKey() == 1 ) {
         dbMoveObjectRight( 1, 1 );
      }

but how do i print the coordinates, i know its going to be in the "loop" part of the code but what is it?

Try this.

+ Code Snippet


char coords [ 256 ] = "";
		strcpy ( coords, "Coord's = " );
		strcat ( coords, dbStr ( dbObjectPositionX ( 1 ) ) );
		strcat ( coords, dbStr ( , ) );
		strcat ( coords, dbStr ( dbObjectPositionY ( 1 ) ) );
		strcat ( coords, dbStr ( , ) );
		strcat ( coords, dbStr ( dbObjectPositionZ ( 1 ) ) );
		dbText ( dbScreenWidth ( ) - 20 - dbTextWidth ( coords ), dbScreenHeight ( ) - 40, coords );

Should print something along the lines of

Coord's = 123,232,657 being x , y ,z

Stuck in the land of the confused! and loving it!

hmm...i put it in like this:

+ Code Snippet

	while ( LoopGDK ( ) )
	{
   
      if ( dbUpKey() == 1 ) {
         dbMoveObject( 1, 1 );
      }
      if ( dbDownKey() == 1 ) {
         dbMoveObject( 1, -1 );
      }
      if ( dbLeftKey() == 1 ) {
         dbMoveObjectLeft( 1, 1 );
      }
      if ( dbRightKey() == 1 ) {
         dbMoveObjectRight( 1, 1 );
      }

		//print text of object 1 coordinets
		char coords [ 256 ] = "";
		strcpy ( coords, "Coord's = " );
		strcat ( coords, dbStr ( dbObjectPositionX ( 1 ) ) );
		strcat ( coords, dbStr ( , ) );
		strcat ( coords, dbStr ( dbObjectPositionY ( 1 ) ) );
		strcat ( coords, dbStr ( , ) );
		strcat ( coords, dbStr ( dbObjectPositionZ ( 1 ) ) );
		dbText ( dbScreenWidth ( ) - 20 - dbTextWidth ( coords ), dbScreenHeight ( ) - 40, coords );
		
		// update the screen
		dbSync ( );
	}

	// return back to windows
	return;
}

but i got 8 errors that include:

Another option

dbText(10,10,dbStr(dbObjectPositionX(1));

So many ways to skin a cat - but the cat isn't happy!

(Glad you're making progress bro) Email again if you get really stumped and the forums aren't helping... but as you can see - every one here is pretty darn helpful!

+ Code Snippet

	
//print text of object 1 coordinets
		char coords [ 256 ] = "";
		strcpy ( coords, "Coord's = " );
		strcat ( coords, dbStr ( dbObjectPositionX ( 1 ) ) );
                strcat ( coords, dbStr ( dbObjectPositionY ( 1 ) ) );
	        strcat ( coords, dbStr ( dbObjectPositionZ ( 1 ) ) );
		dbText ( dbScreenWidth ( ) - 20 - dbTextWidth ( coords ), dbScreenHeight ( ) - 40, coords );

Try that, Its probally my attempt at using "," As spacers, if you can live with one long readout without spaces give that ago, Or split it up into multiple dbText Commands one for each x,y,z and just move them down or up the screen a little for each.

I think its seeing the ","'s as a normal part of the command not a string. Odd tho i figured dbStr() would counteract that..

you could always try changing it to something like a - instead of the ","'s

Eitherway I hope this gives someinsight into what todo. and a chance for me to give something back to the community ^_^

How about:

+ Code Snippet

char coords [ 256 ];

sprintf (coords, "Coords= %d, %d, %d", dbObjectPositionX ( 1 ),
    dbObjectPositionY ( 1 ), dbObjectPositionZ ( 1 ));

dbText ( dbScreenWidth ( ) - 20 - dbTextWidth ( coords ), dbScreenHeight ( ) - 40, coords );

It makes use of the C standard library string formatting to combine the multiple statements into a single statement.
