vsip
by llo_oII
vsip connects Valkyrien Skies ships with Immersive Portals, so portal frames can ride along on a moving ship and portal views stay correct.
What it does
When a portal frame is made of blocks that belong to a Valkyrien Skies ship, the frame is carried by the ship and its portal face follows the ship as it moves and rotates. Only the frame blocks that are physically transformed with the ship move this way. Plain portals that are not attached to a ship stay exactly where they were built.
The mod handles bidirectional portals between the Overworld and the Nether natively through Immersive Portals. Chunks of a ship stay loaded and tracked when a portal leads into another dimension, entities seen through portals render correctly, and a client-side guard stops ships from being removed by mistake on the client. Teleport destinations stay correct when a portal view is used.
vsip is a Forge mod for Minecraft 1.20.1 and is built with Java 17. Both Immersive Portals and Valkyrien Skies are needed alongside it, and the environment is client and server, so the server and every player need it. The mod is released under All rights reserved and is not open source.
