Ogre 3D 1.7

Time for action — creating a spotlight

We will use the code we created before and modify it a bit to see how a spotlight works:

1. Delete the code where we created the light and insert the following code to create a new scene node. Be careful not to delete the part of the code we used to create LigthEnt and then add the following code:

   Ogre::SceneNode* node2 = node->createChildSceneNode("node2");
   node2->setPosition(0,100,0);
   

2. Again, create a light, but now set the type to spotlight:

   Ogre::Light* light = mSceneMgr->createLight("Light1");
   light->setType(Ogre::Light::LT_SPOTLIGHT);
   

3. Now set some parameters; we will discuss their meanings later:

   light->setDirection(Ogre::Vector3(1,-1,0)); light->setSpotlightInnerAngle(Ogre::Degree(5.0f)); light->setSpotlightOuterAngle(Ogre::Degree(45.0f)); ...
