Status: Working
I am currently planning to move everything from ItemsAdder to CraftEngine, even though I will suffer converting all resources, It is worth it.
The reason on why I moved from ItemsAdder is there is not much features than in craftengine, as follows:
1. "Inventory" removal text for custom GUIs
2. 1.21.11 support (main reason on why I moved)
3. CraftEngine uses a different approach to render custom blocks/items and armours. They do not need any ItemsAdder NBT. They are all server-side just with the client-side resource pack.
4. Faster loading speeds async
5. CustomCrops textures DO NOT currently work on ItemsAdder (probaly 1.21.11 support to blame)
6. CraftEngine is built for heavy-servers and uses vanilla behaviours and hitboxes. CraftEngine has support for doors/slabs/trapdoors/stairs which ItemsAdder lacks.
7. More..
I might as well also convert most resources in NulledVault for a CraftEngine configuration (my mimics pack first) for the community
For t0r, please update the resource to 0.0.69 Advancements, the experimental jar is in their discord server. Many thanks if you do.
