  The multiplayer is getting a major update - testing open

  Hey, Colonists! If you are following our Discord, you probably know that my focus went to improving multiplayer so it's fully playable even with a rough Internet connection. I spent the last 3 weeks making every system in the game bulletproof and fully reliable even with 500 ms delay or 25% packages being lost 😱 In the post, I want to share progress and let you try it out with a custom branch. The official release will come in about 2 weeks. NEW SYNCINGWith the new initialization not using begin play but waiting for all systems to be fully replicated, it is now 100% sure that syncing will eventually succeed.There were some actors in the game using Begin Play, so they got all modified to use a new, reliable path.RELIABLE CLIENT SIMULATIONHaving reliable client simulation with 1000 ms is not an easy task. There are many ways to make resources move ahead of a server or behind the server.There are two types of corrections right now that allow for a 100% replicate outcome. If the client has already pushed something in the wrong direction, resources are simply teleported back. This happens for the entire chain that was wrongly pushed. If the client is behind and there are awaiting pushes, server is overriding the simulation, allowing for synchronized moves. This is a saving situation where the server removes the conveyor belt, and resources cannot cross the gap. Right now they will still move like it was a conveyor belt there.RESOURCES TRACKED WITH IDsEvery resources in the game has it's own unique ID that is set by the server. This makes it easier to find exact location and do correction if needed.This also resolves the removal of moving resources, as many times clients could accidentally remove resources in adjacent cells.JUNCTIONS - STABLE MERGE Even if the previous merge was working quite well, it is now improved for multiplayer to guarantee that all resources are always matching between client and server.Devices and logic blocks are now creating conveyor connections....

  Improvements & fixes

  Hello Colonists! There was a small update today. Please check the the changes below. Water stops crafting when the water tank is full! No more wasting ice cubes! Gas rigs will also stop if there is no capacity in the gas tanks. When a new gas tank is created or gas is consumed, they will resume extraction. Radar no longer requires titanium rods, since titanium is obtained in the further stages of the game.

  Endless crafting is back, new storages, improved interactions

  Hey Astro Colonists!It's time for another big quality update that I've been preparing for you for the last 2 weeks and ended up publishing at 4am :) There are plenty of new changes, so let's dive in!Endless craftingYes, the crafting not being interrupted is BACK! By default, as long as the device has enough resources to craft or resources to mine/pick, it will operate! It's now fully up to you how you control the flow. It is possible to limit both inputs and outputs. They will be respected and crafting - power consumption will be reduced if the limit is reached. Inputs of crafting devices are still limited by stack sizes, so use new devices and bigger storages wisely!Controlling overflowTo better control automation resources flow, now it's possible to use Incinerator to remove them from the game or inventory Trash Bin 🗑️New interaction & switching axesWhen starting to drag, the game detects if it's a floor or wall surface and suggests a mode. This way, placing something directly on the wall is no longer a problem.Default placement can be switched by pressing F, so even if you start selecting a conveyor belt, you can select a horizontal grid or place multiple lines of conveyor belts at once!Here, water pipes create a horizontal grid.Floor is no longer blocking, so there is no need to navigate around it.It is now super easy to select foundation right under the floor.Balance & recipesWhen designing new recipes, I tried to better balance the use of individual resources.Above all, it was necessary to reduce the consumption of ice, and secondly of copper.Next, it was important to increase the use of iron. A new resource was born—a ROTOR that uses iron and uranium.The availability of glass, quartz, and stone has also been adjusted.stone consumes only 20 water (instead of 50) and requires 6 units of earthquartz requires 10 Earth (instead of 20)In addition to making the mining of quartz/stone accessible, depth of drills was increased:to -12 from -8 for giant drill-8 from -5 ...

This came to me unexpected, since I believe the state of the game is way better than it was when coming out to Early Access almost 4 years ago.It was a very long journey with 7 major updates and hundreds of improvements, so I want to continue to improve state of the game. It makes sense to save it, so more players can discover the game and enjoy it like me!I think an update like thi...
