The radar provides various indicators and displays them relative to the player's view. The player's position is at the center of the radar, with north in front of the player.
A blip is a colored circle representing a particular actor. Blips will usually appear once they enter line of sight for the first time; for monsters, they also appear once the monster has woken up from gunfire. If a blip is beyond the visible distance of the radar, it will change into a pointed arrow along the edge.
The table below describes the various colors of blips:
| Default Color | Target | Technical |
|---|---|---|
| Red | Living monsters | Has ISMONSTER and COUNTKILL flags. |
| Blue | Living allies | Has FRIENDLY and SHOOTABLE flags. |
| Yellow | Key items / interactive objects | Derived from Powerup or Key, or has USESPECIAL or BUMPSECIAL flags. |
| Green | Regular items | Derived from Inventory and has no COUNTITEM flag. |
| Magenta | Collectible items | Derived from Inventory and has COUNTITEM flag. |
| White | Objects | Has either SHOOTABLE or FRIENDLY flag (but not both). |
In multiplayer, other players will be represented by pips (player blips). These are larger circles marked with the first letter of the player's name. A pip will display in the respective player's profile color.
When a player dies, a light-red blot will appear for a few seconds in the area where he or she died.
The bright region in the radar indicates the player's current field of view. Any indicators such as blips inside this region will be in front of the player in the 3D view.
When a particular indicator (blip, pip, or blot) is above or below the player, it will display higher or lower on the radar. For blips and pips, a vertical line will indicate the relative altitude. This feature can be turned off in the settings.
The edges of the map will be displayed as an outlined red box on the radar.
When a notable amount of red blips (monsters) appear in a short period of time, an audio indicator will play. This indicator can be turned off and the volume adjusted in the settings.
This addon provides many options. The settings are located in a dedicated submenu under HUD Options>Radar Options. You can turn the radar on/off, change the appearance, and control specific features:
| Option | Description |
|---|---|
| Display position | Controls which corner of the screen to display the radar, or turn off the radar entirely. |
| Enable in deathmatch | Enables players to see the radar even in deathmatch. This is a host setting and cheats must be enabled to turn this on. |
| Draw under HUD | Whether the radar displays under or over existing HUD elements. |
| Radar scale | Global display scale of the radar and indicators. |
| Radar transparency | Radar's transparency (alpha channel) to tune its intrusiveness. |
| Radar X offset | Horizontal offset of the radar display, in screen pixels. Positive values move radar towards the center of the screen. |
| Radar Y offset | Vertical offset of the radar display, in screen pixels. Positive values move radar towards the center of the screen. |
| Blip types | Enables/disables specific radar blip types. |
| Blip colors | Allow the user to customize colors for each blip type. |
| Show blip altitude | Turn this off to hide altitude indicators. This is useful for smaller screens. |
| Show respawned items | If sv_itemrespawn is enabled, items are allowed to reappear on the radar after respawning. Turning this off will keep the item's blip hidden after being picked up the first time. This option can help clean up the radar for larger maps with lots of items. |
| Alert volume | Changes the volume of the alert sound. Set to zero to turn the feature off entirely. |
