I'm just starting to adjust to darkGDK, and i'm experimenting with a semi-tile based RPG; the player runs around on typical rpg maps, interacting with objects in a typical fashion, but scattered through these maps are essentially grid-like matrixes, where an action can be performed on individual tiles. having only just started, i'm trying to weed out the basic movement and camera control.

the problem
if i leave the camera directly above the object, there is no problem with it turning to face the same direction as the player. However, when i set the camera to hang back, so the player can be seen, when the player turns, the camera turns the same way, causing it to look AWAY from the player.

question
how can i make my camera follow my player in a typical rpg fashion? (hanging back, a bit above, facing the back of the character)

this is my game loop:

+ Code Snippet

while ( LoopGDK ( ) )
	{ 
                // set camera to sit slightly behind and above player
		dbPositionCamera (dbObjectPositionX(1), dbObjectPositionY(1) + 10, dbObjectPositionZ(1) - 20);

                // set camera to rotate with player
		dbSetCameraToObjectOrientation(1);

		// move the player forwards
		if ( dbUpKey ( ) )
			dbMoveObject ( 1, 1 );

		// move the player backwards
		if ( dbDownKey ( ) )
			dbMoveObject ( 1, -1 );

		// rotation
		if(dbLeftKey ())
			dbTurnObjectLeft(1, 1);

		if(dbRightKey())
			dbTurnObjectRight(1, 1);

		dbSync ( );
	}

please and thankyou!

try this:

+ Code Snippet

// set camera to sit slightly above player
dbPositionCamera (dbObjectPositionX(1), dbObjectPositionY(1) + 10, dbObjectPositionZ(1));

// set camera to rotate with player
dbSetCameraToObjectOrientation(1);

//move camera backwards
dbMoveCamera(-20);

Thanks, but i'm still faced with the problem of the camera not continuously looking at the player object.

i tried this line:

+ Code Snippet

dbSetCameraToFollow(dbObjectPositionX(1), dbObjectPositionY(1), dbObjectPositionZ(1), 0, 10, 10, 50, 0);

with syntax:

+ Code Snippet

void dbSetCameraToFollow ( float fX, float fY, float fZ, float fAngle, float fDistance, float fHeight, float fSmooth, int iCollision )

this partially solved my problem, the player stays on screen almost all the time, which is completely acceptible. However, the camera doesn't always remain behind the player, it stops while facing side-on or even front-on.

The ideal solution to my problem would have the camera tailing along behind the character with little freedom.

Do you want the camera to always be looking at players back(camera turn and reposition behind player) or do you want the camera to generally be facing the same direction at all times (camera just reposition)?
