            This is a really cool tutorial.  It has the basics you need for creating an RTS game!

!!Using CEGUI and OIS for terrain selection
I had to make the following changes to my code to get this working with OIS.

1) Set the window width and height for MouseState, eg:

~pp~     const OIS::MouseState &ms = mMouse->getMouseState();
     ms.width = width;
     ms.height = height;
~/pp~
If you're using the practical application tutorial (((Practical Application - Let's Get Started))), you can achieve this simply by calling eg.     handler->setWindowExtents(1024,768);  after creating the InputHandler.

2) The following:

~pp~          Ray mouseRay = mCamera->getCameraToViewportRay( e->getX(), e->getY() );
~/pp~
becomes:

~pp~         Ogre::Real normX = Ogre::Real(evt.state.X.abs)/evt.state.width;
         Ogre::Real normY = Ogre::Real(evt.state.Y.abs)/evt.state.height; 
     Ogre::Ray mouseRay = camera->getCameraToViewportRay( normX, normY );
~/pp~
3) This had me scratching my head for a while.  You need to initialize the CEGUI mouse cursor at the origin:

~pp~     CEGUI::MouseCursor::getSingleton().setPosition(CEGUI::Point(CEGUI::Vector2(0,0))); 
~/pp~
[http://www.wreckedgames.com/forum/index.php/topic,353.0.html|This post] on the OIS forum was essential in getting it to work.  Maybe someone with more confidence in their understanding can add this information to the tutorial?

!!__Adding Mouse Look__
Find the __TutorialFrameListener__::mouseMoved function and add the following code just before the return statement:

should be:

Just added this pach to the tutorial. : ((User:Tautrimas|Tautrimas)) 19:03, 1 March 2008 (GMT)

!!Terrain Selection
''Ogre provides us with Camera::__getCameraToViewpointRay__; a nice function that[...]''

should be

''Ogre provides us with Camera::__getCameraToViewportRay__; a nice function that[...]''
