can someone help me alter my camera code?

[CameroKid]

Here the code for my 3rd person camera:

Code: Select all

	core::vector3df p = node->getPosition();
 	 core::vector3df r = node->getRotation();

	camx = r.Y + (MOUSE_X - PREV_MOUSE.X) ;
	camy = camy + (MOUSE_Y - PREV_MOUSE.Y) ;

	         camera->setTarget( core::vector3df( node->getPosition() ) );
         camera->setPosition(
            core::vector3df(
               (  cZoom * sin( camx * 3.14/180 ) * cos( camy * 3.14/180 )) + p.X,
               (  cZoom * sin( camy * 3.14/180 )) + p.Y,
               (  cZoom * cos( camx * 3.14/180 ) * cos( camy * 3.14/180 ))  + p.Z
            ));


	node->setRotation( core::vector3df( 0 , camx, 0         )         );

It works just fine (on my comp anyway). My problem is this code treats the y axis as the floor to ceiling axis. I need the z axis to be the floor to ceiling axis. The code and my modeler program don't agree. Can someone help me out?

Hi.

Try rearranging the calculations for your vector values. I'm thinking...

Code: Select all

camera->setPosition( 
            core::vector3df( 
               (  cZoom * sin( camx * 3.14/180 ) * cos( camy * 3.14/180 )) + p.X,
               (  cZoom * sin( camy * 3.14/180 )) + p.Z, 
               (  cZoom * cos( camx * 3.14/180 ) * cos( camy * 3.14/180 ))  + p.Y
            ));

might work.

If not try something else along those lines.

I use Blender, which (opposite of every other 3d app and API I have ever used) uses the Z coordinate for up/down instead of the Y coord.
I think most people just rotate everything 90 degrees on the X axis before exporting.

I fixed it. Thanks

What did you do to fix it then?
