Find the error in each of the following:

Question

a) ```
SceneNode node;
```
b) ```
ColourValue( 0, 0, 255 );
```
c) ```
Root *rootPtr = new Root();
rootPtr->initialize( true, "Window" );
```
d) ```
viewportPtr = sceneManagerPtr->addViewport( cameraPtr );
```

Answer 1

a) The variable node should instead be declared as a pointer to a SceneNode. All of Ogre’s SceneNode functions either take a pointer as a parameter or return a pointer.
b) The ColourValue object can accept parameters only with values between 0 and 1.
c) Ogre uses British spelling, the function is spelled initialise. Also, the render settings must be set before you call initialise.
d) addViewport is a function of the RenderWindow class, not SceneManager.
