With Custom Crosshair, the player enables to edit the color, size, and shape of the crosshair. Because of that reason, mod programmed by Mojang allows the players to create what they think it is a lack in the game. This point is a significant shortcoming from game developer Minecraft Mojang.
However, a first view game has no option function, cannot freely change color, size or crosshair shape. And absolutely, Minecraft interface also has a basic Crosshair. In detail, the first view is a default view. In Minecraft, the player can use three types of vision: First view, second view, and third view. In this mod, the center of the rear sight is a vision of the player, which allows the player to aim a gun at a target more accurate. If you had a chance to experience game FPS where the player attacks the enemy by fast and accurate response ability within many guns from rudimentary to modern, obviously you would be familiar with Crosshair. It just plays a decoration role and does not change a lot available mechanism in Minecraft Vanilla including basic mechanisms and contents such as blocks, tools, weapons, armor,… And Custom Crosshair is such a small mod that you can use it in Minecraft server without any problems about the compatibility or unbalance in PvP mode.
Custom Crosshair Mod 1.16.5/1.15.2 for Minecraft is a Cosmetic Mod.
