| ==== A More Advanced Roaming Ralph ==== | |
| |
| - Get the **advancedralph.py** running and explore the controls, making sure you understand how to control both Ralph himself and the camera (rotating and tilting by approaching the edge of the screen with your mouse; zooming with the mouse wheel). | |
| | ==== Roaming Ralph with some HUDs ==== |
| | |
| | In this exercise you'll start with a fully working 3rd person world with Ralph as your avatar. You'll then add a couple of classic HUD features, namely the **health bar** and the **overhead map**. |
| | |
| | - Get the **advancedralph.py** running and explore the controls, making sure you understand how to control both Ralph himself and the camera (rotating and tilting by approaching the edge of the screen with your mouse; zooming with the mouse wheel). Have the application run in **Fullscreen** mode, simply by changing False to True in the call to **setFullscreen** near the bottom of the code. It is easier to control the camera with the mouse in this mode, but the windowed mode might be better while debugging. |
| - The following code is a **HealthBar** object that can be attached to a scene graph. A health bar can display some fractional property in a graphical manner, such as the health or power of a character. Attach this bar to the Avatar so that the bar appears to be floating over the Avatars head. Make sure you can see it (but it may disappear when you start moving around - see below)<code python> | - The following code is a **HealthBar** object that can be attached to a scene graph.

| - Now add some landmarks to your world and have them show up on your map as little red squares. You can use the **Models/box.egg** object. Initialize a few of these boxes by storing a list if (x,y) tuples and then iterate through the list to place them in the world. You should also be able to send the list directly into the map's **addLandmarks** method and have the locations of the boxes light up. You'll need to fill in the rest of that method. Test to see if this is all working. | - Now add some landmarks to your world and have them show up on your map as little red squares. You can use the **Models/box.egg** object.

| | - If you feel adventurous, change this application into a game where the health bar starts to drop as time passes and the only way to regain full health is to touch a box, which then disappears. You win the game if you reach all the boxes. By randomizing the initial box locations, you'll really need the map to help you play this game. |
