CM:ME Additions
CM:ME Additions is a Forge addon for GregTech CEu Modern that adds Material Flags to the GregTech material system.
What it does
Material Flags are attached to materials in GregTech through code, and this addon extends the set of flags that can be applied. Items for the new flags must be added with KubeJS, so installing the mod on its own adds nothing to the game. Material flags are read with KubeJS using CMMEMaterialFlags, and many kinds of items still lack tags, so scripts may need to cover them. The mod was created mainly for the CM:ME modpack and is especially useful for modpack creators.
Key features
Extra material flags
The addon adds more Material Flags to GregTech materials, extending what a material can carry.
KubeJS item setup
New items for the added flags are defined through KubeJS scripts rather than in the mod itself.
Flag access from scripts
Material flags can be read from KubeJS using the CMMEMaterialFlags class.
