How can I add a new camera and use that view and make it small and fix it in one of the corner of the screen.

I want to do that to have a top view of the environment but that one will be separetly of the original one.


Thanks in advance for your help

You can also find it in the Windows start menu, if Dark GDK managed to install correctly: start menu, programs, The GameCreators, Dark GDK, Documentation, Information.

When it comes to positioning the camera in the screen how can figure it out the coordenates positions or is it gonna be a trial and error method??


void dbSetCameraView ( int iCamera, float fLeft, float fTop, float fRight, float fBottom )

Cuz if there is an actual information about different positions in the screen it will be good to know.

Thanks in advance

Trial and Error or Inferences based on nearby Objects. Thats what I normally do, at least.

LOL

Thanks in advance

The parameters of dbSetCameraView are pixels.
Top left corner of the screen is pixel 0,0.
Default resolution of the Dark GDK window is 640 x 480 unless you change it in your program.
Just give some pixel parameters to that function to size and position the camera view.

P.S. The dbSetCameraView influences only how the view is displayed on the screen, not what the camera shows. To get a top-down view, you need to use dbPositionCamera and dbRotateCamera, just as you would position the default camera as well, only the camera ID number is different. And yes, that is mostly trial and error but you can get a good idea based on the coordinates of other objects on the scene.

To give you an example as well: to position the camera view in the bottom right corner and set it 200 pixels wide, you can use:

The primary camera background is blue, the camera number one background is green. You can change the background colour with dbColorBackdrop or even turn it completely off with dbBackdropOff, but in that case you have to take care of clearing the screen background in each loop.
