| - **Compile and Run the Lab7Main Example** You should now be able to compile and run the provided Lab7Main example application, and you should see a simple object fall down and land on the ground plane. The interaction between the object and the ground is not particularly interesting, so in order to see something a bit more exciting, you should try using the ''TestLevel_b0.mesh'' as the groundEntity instead of the simple plane. Try that (you can accomplish that by commenting out three lines and un-comment one line ;)). | - **Compile and Run the Lab7Main Example** You should now be able to compile and run the provided Lab7Main example application, and you should see a simple object fall down and land on the ground plane.

| | - **Create a Prop Class for Multiple Stars** Take a look at the code that creates a single star object. It's between the comment "Star!" and the comment "Ground!". Replace this code with the instancing of a generic prop class. The constructor of the prop class should take the following arguments and completely create the new object in the scene:<code cpp> |
| | Prop(SceneManager* sceneMgr, const Ogre::String& mesh, Vector3 pos, Vector3 scale, btScalar mass) |
| | </code>And then to create one star in ''createScene'' you would simply do:<code cpp> |
| | Prop* mystar = new Prop(mSceneMgr, "Star.mesh", Vector3(0,10,0), Vector3(1,1,1), 5); |
| | </code>When you implement this class, be aware that Ogre allows you to omit providing an entity name and a scene node name when you create those. Ogre will then simply provide unique names of its own (useful when you want to create multiple instances of this object). Make sure that your class also implements a destructor that deletes the object properly (in the example, you see how the object is deleted in the BtOgreTestApplication destructor). When you have implemented the **Prop** class, test it by creating two instances of the star. |
| | - **Create New Stars with the Mouse** Finally, add a check for a left mouse button **down** state in the ''frameStarted'' method of the ''BtOgreTestFrameListener'' and respond to that state by creating a new instance of the star. You should now be able to easily fill the world with bouncing stars! |
