GeckoLib Mod for Minecraft 1.20.4, 1.20.1, 1.19.4 and 1.19.2, is an indispensable animation engine for running certain animations from other mods. Basically, creators can make use of this add-on to facilitate their creations, and subsequent updates.
In this case, GeckoLib supports complex animations, based on 3D frames, which will make the gaming experience much more user-friendly. Developers will have a lot of mechanics at their disposal that they can modify to make the game much more customisable.
Its fantastic support for simultaneous animations, keyframes with sounds or particles, as well as events or other “vanilla” features, make it one of the most popular Minecraft add-ons. It is also available for a large number of versions, and is constantly being updated.
As with other add-ons, GeckoLib is of no use on its own, as it is only needed by mod makers. However, there are some mods that require its use to run, so if it is not located in the “mods” folder, the game may not start.
Currently, GeckoLib has almost half a hundred million downloads, making it one of the top resources for Minecraft players and creators. In short, its usefulness is simple, to modify the animations of some entities or elements that can be customised by mod developers.
