| VMK 19a Health Pack Class | 
|
 VMK 18
|
 |
| The health pack pickup object class is created in this VMK and the 3D model of the health pack is loaded into the game. The VMK file format has been recently updated to v1.1 so I also show the changes that need to be made to be able to load this new format. |

|
| VMK 20b Arrows Pickup and Respawn | 
|
| VMK 20a
|
| |
| Using the class created in the previous VMK I add the animated arrow pickup object to the game. Updates are made to the Player class and to the Scene class to make this happen. |

| VMK 21b Energy Pickup and Respawn | 
|
| VMK 21a
|

| VMK 22 General Math Update | 
|
|
| A number of small updates are made to the GeneralMath class.
The random number generator function is updated, the swap function is added, and the constant values that use the value of PI are also updated.
For more information about random numbers check out Intro to C++ VMK 16 (coming soon). |

|
| VMK 23 Random Position | 
|
| VMK 22
|
| |
| New functions are created in the Scene class that allow you to randomly place items in the map. Care is taken to make sure that the item will always land on an empty square (not in a wall) and that there is nothing else already in the same spot.
This is used to randomly scatter all the pickup objects in the level and also to randomly place the player when the game starts. |

| VMK 24 Remove Vertex Classes | 
|
| VMK 23
|
| |
| Three classes (Vertex2, Vertex2i and Vertex3) are removed from the game engine in this VMK. These classes are not needed so they are replaced with our Vector classes. |

| VMK 25a Radar Display | 
|
| VMK 24
|
| |
| I start work on the radar map unit by adding the graphic image to the resource files. This video focuses on making the radar map display in the top right hand corner of the screen and also animating it open and close based on the battery power. |

| VMK 25c Radar Sweep Arm | 
|
| VMK 25b2
|
| |
| The arm that sweeps around in a circle in the radar unit is created in this VMK. A new function is also added to the GeneralMath class that will make things easier for us a little later on. |
|

|
| VMK 25d GUI Fade Dots |

|
| VMK 25c
|
| |
| In this last VMK in the Radar Unit section, I show how to make the dots appear when the arm sweeps by them, and slowly fade out of view when the arm moves away from the dot. New functions are added to the Vector2 and Math classes. |
|
|
|
|
| VMK 26 Static UserSettings Class | 
|
|
| In this VMK, I update the UserSettings class and make a static get() function to allow us to retrieve a pointer to this class anywhere in the code without having to explicitly pass a pointer around.

|
| |
| I have supplied the ghost.vmk 3D model with this video to be used to render a ghost on the screen. A Ghost class is created in this video to manage the ghost object in the game. The radar unit is also updated to show a red dot where the ghost is positioned in the map. |
|

|
| VMK 28b Duplication | 
|
| VMK 28a
