BCLib Mod for Minecraft 1.19.3, 1.19.2, 1.19.1 and 1.19, is a necessary and essential add-on for running a wide variety of Minecraft mods. That is to say, in the case of not having this famous complement installed, certain mods will not be able to work at all.
As it is logical, in the case of installing BCLib alone, it would not be of any use, since it will require at least one other mod to be functional. Basically, it is a complement needed to make use of certain features, so it is required by some mod developers.
In addition, the installation is really fast and easy, since you only need to place BCLib and Fabric API in the “mods” folder, inside the famous game location, the well-known “.minecraft”. However, this location may vary depending on the executable chosen for the installation.
It is essential to use BCLib to run certain Minecraft mods, so if you do not have it installed, some mods will not be able to run.
