Programmed as a supported mod, the PTRLib will not provide any effect when installed independently in Minecraft, sometimes these mods only provide a few small items. Most mod developers have programmed many mods using this programming method. Thanks to the existence of these Core Mods, updating, fixing and modifying multiple mods is much more simple. Core mod is a trend with maximum resource savings and can support multiple mods at once. PTRLib Mod 1.12.2 for Minecraft is a core mod of Razzleberryfox, ProfMobius and taelnia, used to run other mods, so it usually appears in the “required” section when installed.
