This is a Derma version of the manually drawn Default Player Class HUD Element which is now gone. It integrates with the UIManager and FontManager and scales with the ScreenSize instead of being a fixed small size.
Players should be ignored for use commands, since it does not actually change things. Also increase the abuse cooldown to 0.5 seconds for non-blacklisted items.
This allows checking if the player is actually alive according to the current player class. Some classes are alive to the game, but not to the actual game mode, for example Spectators are alive, but not really.
This feature allows Hiders to easily tell which prop they will turn into if they press Use. As always, it can be fully configured and even turned off. By default it is enabled and set to Approximate mode.
In Approximate mode, the client is responsible for guessing the best match to the Use key, but does not have any actual influence on what they will really turn into. This will in most cases be enough, as the internal Use test relies on the forward vector, which is checked by this mode. For those requiring more accuracy, there is the Accurate mode.
In Accurate mode, the server is responsible for exactly knowing the best match to the Use key and sending this to the user. This has a server performance impact that scales with the player base and the rate at which these updates are performed can be configured. This mode is affected by lag and packet loss, so only really useful for high performance LAN servers or testing.
Even though git internally knows the difference between upper and lower case, all of it's commands rely on the file system to do so as well. This results in incorrect behavior when renaming A to a for example, as the source and destination is identical on the file system according to git. Windows does support such renames, but git seems to shit itself.
