Camera system

[capture]

I have a request i would love to see put into Ogre. It would be really cool if there was a way to attach a camera to an node or entity. And have Ogre take care of making sure the camera stays in the correct place for use in a FPS or something or for being a third person camera.

Code: Select all

SceneNode::attachObject(yourCamera);

yeah there is that, but i was thinking something that will cause it to follow a character and look at the correct place as the character rotates or whatever.

I think there is an auto-tracking functionality that does this. But frankly, for any decent game camera system that is likely way to simple. Good camera movement, however, depends strongly on the game and the surroundings, so I don't think that Ogre is suited to provide that.

That logic is too application-specific as to be treated by Ogre itself. There could be additional layers to provide certain functionality, but in my honest opinion, that layer doesn't belong to Ogre.

I couldn't agree more to that request

[stoneCold]

I can just add to the previous speakers opinions, this is just way too application specific, and ogre shouldn't be responsible for that task.

You get a very! flexible camera API when using ogre and the wiki also got loads of articles about camera management.
Now go, use it/read them

You could add your camera to a child node of the object you want to track and use setAutoTracking to fix the camera to the object.

Code: Select all

Ogre::Entity* robot( mSceneMgr->createEntity( "robot", "robot.mesh" ) );
Ogre::SceneNode* robotnode( mSceneMgr->getRootSceneNode()->createChildSceneNode( "robotnode" ) );
robotnode->attachObject( robot );
robotnode->setPosition( 0, 500, 0 );

Ogre::SceneNode* cameranode = robotnode->createChildSceneNode( "camerayawnode" );
cameranode->setPosition( Ogre::Vector3( 0, 100, 250 ) );
cameranode->setAutoTracking( true, robotnode );
cameranode = cameranode->createChildSceneNode( "camerapitchnode" );
cameranode->attachObject( mCamera );
