TravellingDimension

Each portal dimension divides coordinates by sixteen on the way in and multiplies them by sixteen on the way out, and the arrival point is the nearest valid spot to the computed position. The mod adds a second overworld-like dimension called VOYAGE alongside the vanilla nether route, and the nether behaves as it does in vanilla. Ice highways and rail lines built in the travel dimension cost sixteen times less material to cover the same real distance back home, which is the main reason the dimension exists.

The portal is built from amethyst blocks in a frame whose interior is 21 wide and 21 tall, lit with an igniter by right click. Two settings, portalFreeSize for VOYAGE and netherPortalFreeSize for the nether, lower the minimum size to 1x1 and raise the maximum with portalMaxSize and netherPortalMaxSize. Only the accepted dimensions change, so the rule for scaling coordinates ignores the portal size, and the mod is set up as a client and server mod, so both the server and every player need it. Required dependencies are Fabric API and Fabric Language Kotlin, and Cloth Config API and Mod Menu are optional.
