For users searching for a more in-depth explanation of the custom font or who are interested in creating their own font, skip ahead to Creating Your Own Crosshairs.
This method's advantages are that the crosshair’s color can be changed easily and it can be animated to change color upon damage (whenever you hit someone), a feature found in many of the Quake games, precursors to the TF series in several ways. The first method is to simply insert a text box into the hud and then load a custom font which contains the crosshair of your choice. There are two main methods of doing this: text crosshairs and image crosshairs. That is, something that will tell them where the center of their screen is. One technique users have been using since as early as 2009 is to place a control into their HUDs to serve as a crosshair. res files, can be edited by the user to change existing bits and pieces, which will henceforth referred to as controls, or, more interestingly, at least for our purposes, add new controls. It is controlled by text documents that determine positioning, size, visibility, color, and everything else about all of its moving bits and pieces. It displays information relevant to the user while in-game, such as health, ammo, the scoreboard, and much more. Team Fortress 2's heads up display, or HUD as it is colloquially known, is a user interface, also known as a UI. More advanced users should skip ahead to Implementation. This part of the tutorial is a basic overview of what exactly a HUD crosshair is. Credit for this Guide goes towards Komorebi. This guide has been ported over from the old HUDS.TF Guides section.
