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.
Like with states, allows reuse and prevents missing elements and uses the Lua engine to do the lookup instead of the Lua parser. Slightly faster, but may not be directly obvious in use.
The original game mode had a Scoreboard and now Prop Hunt Extended also has one. As usual, it has separation by team (Spectator, Hider, Seeker) and has the game mode logo in the top left. This score board is kept very simple and is non-interactive.

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.
Garry's Mod registers lua files in the order they appear, and will immediately run cl_init.lua once it is registered. This occasionally caused includes to error.
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.
The meta object is extended by some commonly used functionality that Garry's Mod does not expose directly. Some of these are Server only and will produce wrong results on the Client, also due to Garry's Mod not exposing things properly.
