Camera won't rotate [solved]

[Apoptyzm]

Hi,
I have weird thing...
I want my camera to follow a sphere for example, but it points one point all the time and it wont change ;x

Code: Select all

//I initialized Camera
Camera = irrScene->addCameraSceneNode(0,vector3df(0,0,0),vector3df(0,0,0),-1);

//later I've set it up

camerapos= vector3df(0,1.5,-5);
Camera->setParent(BodyNode);
Camera->setPosition( camerapos );
Camera->setRotation(vector3df(0,0,0) );

//and it points global(0,0,0) all the time not relatively to parent sphere.

//so on every frame I tried to point the camera to look at the point where the sphere looks

camerapos = conv::btV2irrV( trans.getBasis()[2]*57.2957795);
Camera->setRotation(camerapos);//camerapos is good and it differs at every frame (from circa -50 to 50)
vector3df v = Camera->getRotation();
//but "v" is messed up.. i get smtg like 1.000e+008 etc

any clue

Regular cameras don't respond to rotations. They look at a target.

Instead use:

Camera->setTarget(objectToLookAt->getAbsolutePosition());

The objectToLookAt might simply be an empty node child of the sphere.

If fact, objectToLookAt might even be child of the camera, so that when you rotate the camera, the target moves.

thanx for reply.

I thought that normal camera's dont have setTarget, but i've found that my pointer was an IsceneNode, not CameraNode ... doh

still I wonder why i cant rotate it with setRotation..
