ID Relocator is a high-performance tool that solves the most prevalent issue in Minecraft 1.7.10: the Global Entity ID limit. The default ID limit in Minecraft is 255; thus, if OreSpawn, Godzilla, and MLP is installed, the application will crash, and it will output an error message indicating that the specified entity ID is already reserved by some other entity.
The program applies ASM to tweak the Minecraft core and Forge to increase the maximum number of global entity registries from 255 to 32,767. Additionally, the program automatically assigns registered entities to free slots, which ensures that the engine does not exceed the Global Entity ID limit and that the registered entities are able to run in the engine concurrently.
Mod developers can benefit from this utility because the "No more entity indices left" error will no longer appear. By designing this utility to minimize the probability of causing issues in the Minecraft installation, players are able to run their installed mods with high performance without encountering errors.
