FeatureCreep is an upcoming ModLoader and Modding API for Minecraft 26.1+, it will make it easier for you to make multiversion mods. We provde common apis which are less dependent on version top make it easier to support multiple versions and it has the ability to work on top of a bunch of other mod loaders allowing your mod to passively support many of the existing modloaders across many different versions. Some platforms we currently support include ModLauncher (MCForge, NeoForge, PillowMC), FabricMC (and derivatives). The Modloader and some of the APIS will also exist for other programs such as DangerZone and Live2D Cubism.

Planned Version backports:

NeoForge/PillowMC 1.20.5-1.20.6+

MCForge 1.20.6+

Vanilla 1.21.11+

FabricMC 26+

NilLoader 26+

Right Now only the 26 version is published but we will add the other soon.We will maintain a 3 major version maintinance cycle.

 

We have changed a lot since FeatureCreep 4 so mods made for FeatureCreep 4 are not all likely to work on FC6+, however we will maintain a basic compatibility layer until FeatureCreep 13.

 

DEV TUTORIALS COMING SOON!
