Time for action — adding a point light

We will create a point light and add it to our scene to see the effect it has on our scene:

1. Add the following code after setting the material for the plane:

   Ogre::SceneNode* node = mSceneMgr->createSceneNode("Node1");
   mSceneMgr->getRootSceneNode()->addChild(node);
   

2. Create a light with the name Light1 and tell Ogre 3D it's a point light:

   Ogre::Light* light1 = mSceneMgr->createLight("Light1");
   light1->setType(Ogre::Light::LT_POINT);
   

3. Set the light color and position:

   light1->setPosition(0,20,0);
   light1->setDiffuseColour(1.0f,1.0f,1.0f);
   

4. Create a sphere and set it at the position of the light, so we can see where the light is:

   Ogre::Entity* LightEnt = mSceneMgr->createEntity("MyEntity","sphere.mesh"); Ogre::SceneNode* ...
