    Short Distance Teleportation - Interstellar Rift Development update 159

    Happy new year to all of you! We’re happy to start the new year with an experimental update. In this patch we add the new local teleporter, improved rifting effects, and multi threaded star systems.

    First up, the local teleporter is a new interior device that currently takes up one tile. (More versions with position offsets will be available before the patch goes live.)
    You will need at least two of this device, as local teleporters need to be linked up to each other. Linked teleporters will automatically teleport you between them, once you step on the teleport pad.
    When the device is turned off it will display a screen with available local teleporters on your ship.

    Anyone can use the teleporters if they are on, but the permission system prevents you from turning them on and off if you lack the proper authorization.

    As a part of our rifting updates we have improved the way models load in after a rift, so you no longer see the ship slowly coming back together again once you come out of a rift. We’ve also added visual indicators that the ship is rifting.

    The biggest change in this update is that different systems are now being run on different cpu threads. This will hopefully increase the performance of servers as it frees up more processing power for each system. This is a major change in how systems run on the backend and we will be keeping a close eye on any issues that are encountered during the experimental run.

    This might have unforeseen consequences so we made it an option that can be toggled in the server settings, and currently the default value is false.

    Look for "MultithreadedSystemUpdate" in your server.json file to activate multi threading.

    This file can be found in the following folder:

    For all the changes and bug fixes please see the patch notes.

    Thank you all for playing, and see you star-side!

    - The Split Polygon Team.

Interstellar Rift is a First Person Starship Simulator with an emphasis on open world exploration and multi-player interaction. Players will need to survive in a hostile galaxy with their own custom designed and constructed starship. Space is vast but you wont have to face it alone, other players will be able to join you aboard your ship to help you man your vessel’s more complex devices and equipment.

Customize your ship

Our ship design tool will allow players to quickly create or modify existing ships to suit any possible situation. By mining and gathering resources from across the galaxy you’ll be able to construct more powerful and efficient components so you and your ship can face any challenge. Equip drone bays, to have a fleet of autonomous helpers, or build the enormous strip miner, to extract resources from rare large asteroids. From a small shuttle to a large warship, every ship can be what you want it to be.

Explore the galaxy

Help out factions to gain their trust and spread their influence throughout the universe. Build new stations, defend them from invading alien forces, or destroy them to lower a faction's influence. Build a rift generator to travel to other solar systems, and repel the alien forces to prevent them from taking over sectors. Whether you're flying a large cargo hauler, a capitol battleship, or a mining barge, there will always be missions available that match with your ship. Venture out to find rare resources to build special equipment, or buy special items that can be sold for profit. Interstellar Rift is build to suit any play style.

Advanced ship simulations

Building your ship is only the beginning as it will require plenty of work to keep running. You will have to manage your fuel and power levels, keep systems from being infected by alien parasites, make sure devices stay in working order, and much more. Players who are in a crew can rely on each other to maintain the ship, and for solo players there are automation options such as the ACTR (automated cargo transfer relay), to help out with the heavy lifting.

A threat beyond measure

Throughout the galaxy, mysterious rifts are opening up, spilling out a dangerous alien race called the Skrill, that when left unchecked will seize control of the region. Players must band together to stop these enigmatic invaders before they threaten the safety and profits of their enterprises. Between the dangers of pirate drones, vicious Skrill, and other human players, pilots will have to be on a constant lookout!
