Camera rotation

[unclejoe]

Hi folks,
I'm trying to rotate the camera with the up-key, using the following code in my event receiver:

Code: Select all

case KEY_UP:
  cam->setRotation (cam->getRotation () + core::vector3df (0, 5, 0) );
  break;

but the camera simply won't rotate. What am I doing wrong?

as far as I see: the ICameraSceneNode class has to setRotation(). If you want to rotate your camera, you have to get a node pointing to that class and then, if the camera eg. has been created with addICameraSceneNode rotate the camera by using the setTarget(thistarget) method, where thistarget is a vector3df type that holds the absolute positions of the point the camera should look at. (so if the cam is at ->setPosition(vector3df(0,0,0)) and you say setTarget(vector3df(0,1,0)) the cam will look up.
If you want to have constant rotation you have to constantly change the target (eg in the progs main loop).

unclejoe: What he's trying to say in simpler words is that the camera's rotation is decided by its target (vector).

Code: Select all

case KEY_UP:
    cam->setTarget(cam->getTarget() + vector3df(0.f, 5.f, 0.f));
  //cam->setRotation (cam->getRotation () + core::vector3df (0, 5, 0) );
  break;

M'kay, so i should change the target the camera is looking at. i just thought i could rotate it, cause the camera class is inherited from ISceneNode, but clearly the function setRotation () doesn't do poop...

LOL, this forum automaticly changes the word sh*it into poop!!!!!
