| Particle Accelerator Pixels are here!!! (1.0.58) This update finally adds particle accelerator pixels! They are currently craftable through the same category as the lasers, require super-heavy isotopes (so you have to do the manually isotope production to some degree first), and use power from the grid (currently 16 kJ per tick, to match the Particle Accelerator tool). There is an Alpha Particle Gun, Neutron Gun, and Proton Gun :) Other addit… | 25596335 | |
| Quality of Life Updates! (1.0.54) This update adds some quality-of-life improvements that players requested: · QoL: Larger sim areas now allowed: up to 10x10 chunks - this makes it a lot easier to run large scale machines all at once and pull the camera zoom way out :) · QoL: Buttons in the Select World Screen to sort the world list Alphabetically or by Last Played (the buttons appear when you have more than one world listed) ·… | 25429171 | |
| Wrench shape settings and more hotfixes! :) (1.0.53) The Wrench tool now has the same shape options as all the other tools. :) This is convenient if you want to have alternating filters allow different things through a filter row. With this, I think all the current tools are aligned in how they handle the shapes you can draw and their UX. Other things in this build: · BUGFIX: Can now pick up, drop, build, and mine materials while simulation is pa… | 25403035 | |
| Monster Ring and other Hotfixes :) (1.0.52) This update adds some hotfixes: · BUGFIX: Monster Ring wasn't functional before - now it works :) It adds to the max monster count and doubles the monster spawn rate. This also makes it possible to spawn monsters in Creative Mode to get ectoplasm or slime. · BUGFIX: RNG (random number generation) fix for IsReactionValid, should make reaction rates more consistent regardless of position · BUGFIX… | 25333453 | |
| RNG and other fixes :) (1.0.51) This build adds a number of bugfixes. The biggest one is that random number generation (RNG) is revamped to prevent inconsistencies that were present before. RNG volumes are now generated in a way to give guarantees that they will visit the entire value range for any given position, and some other fixes with how the RNG functions were being called fix an issue where the call would only get a su… | 25276053 | |
| Soda :) (1.0.47) This update adds Phosphoric Acid and some ways to create a variety of sodas and cola :) (making soda is going to be important for an upcoming Slime Ranching update) Apatite also now mines into 3 variants: Fluorapatite, Chlorapatite, and Hydroxylapatite, each of which can react with Sulfuric Acid to obtain Phosphoric Acid. The three types of mined apatite can also be blending with water to form… | 25176263 | |
| Hotfixes (1.0.42) Here are a couple quick hotfixes while I'm working on some bigger updates: · QoL: delay resaving the *.universe file when the player restores an element so it doesn't create a pause - this is what was causing the freezing for some people when completing an element in the ship progression, so I wanted to get this in right away · QoL: changed the way spawning is suppressed by built pixels so that… | — | |
| Hotfixes and Andesitic Lava Chemistry (1.0.40) Today I did a bunch of bugfixes, and also made adjustments to lava! Andesitic Lava now cools into Sodium Aluminosilicate, and I added reactions for Sodium Aluminosilicate and its downstream products: Sodium Silicate, Sodium Aluminate, and Aluminum Hydroxide, to connect it into other parts of the reaction web. :) Bugfixes in this build: · BUGFIX: Rocket and Nuke Counters were not disappearing an… | — | |
| Quality-of-Life Improvements! (1.0.32) A bunch of quality-of-life improvements in this build! 1.0.32: · Added "Show HUD" toggle on F6 · UPGRADE: Recharge Rate 4 added, to make Particle Accelerator beam easier to use · Added Credits Screen · Made the achievement for the best ending also trigger the “escaped the asteroid belt” ending · Moved the Sim Loader pixel to the first category of craftable pixels; it feels like it's better not… | — | |
| Save System Hotfixes (1.0.31) This adds a few things, mostly related to the save system: · put in better containment for when errors occur on planet segments in the loading and saving processes · in situations where a planet segment didn't get saved properly, will load as empty instead of being filled with sand · BUGFIX: fixed a bug where not all active chunks would necessarily get marked to be saved · BUGFIX: made the "Sav… | — | |
| Updated Save System! We have big updates to the save system in this build! The new save system will save everything related to a particular world into a singular .universe file in the Worlds directory (currently about 120MB). It does atomic saves and maintains a list of 5 rolling backups, so it should be much easier to restore if something happens and should sync much more easily using Steam Cloud (also will help k… | — | |
| Performance improvements, started adding videos to menus :) (1.0.29) With this update I have mostly made some improvements to memory allocations and performance that should help to reduce stuttering for players who have been experiencing it. But also, I found out how to play video clips in Godot and started adding video previews to the crafting menu! The first three categories are about done - over the next couple days I will keep filling these out until we have… | — | |
| More Quick-Fixes (1.0.28) Just a couple quick things today: · QoL: If something is already in your Material HUD Bar and you Middle-mouse-button it to select it, it'll just select the existing material slot instead of assigning a duplicate · QoL: Walk-Through-Walls Boots only operate when in Jetpack Hover Mode or when using the Jetpack if in Impulse Mode - this makes bases and platforms much more easily compatible with t… | — | |
| Added Temperature Sensor! Temperature Sensor pixels are now in the game! These should be handy for temperature regulation in machines. :) You can use Rotate and Program (as well as the Wrench) to adjust the settings. Possible values are 500K, 1000K, 1500K, and 2000K. When the Temperature Sensor pixel reaches that temperature or higher, it generates a signal, and turns off as soon as it drops below. Also today: · QoL: fi… | — | |
| Balancer, Splitter, and Simulation Controls! Some great updates today: the Balancer and Splitter are now added to the game! The Balancer takes in inputs from the left and the right in a perfectly alternating manner, and drops them below. Each time it takes an input from the left or the right it switches state, and it only advances when it actually receives an input, so you can use it to create perfect 50/50 mixtures of things. The Splitte… | — | |
| Berry Bushes now plantable! And other hotfixes... Berry bushes can now finally be planted using Berries :) They grow very quickly (will probably get some tuning in the future), so now you can create your Berry and Wine auto-farms! Other hotfixes: · BUGFIX: another attempt at making the jump/jetpack-impulse fully framerate independent; hopefully this works for everyone now :) · BUGFIX: fixed Rotation 'R' when using the Mega Multitool · BUGFIX:… | — | |
| Some hotfixes for Survival Mode Here are some quick hotfixes and additions for Survival Mode! · Wire-blocks now allow materials to pass through vertically or horizontally, but block on diagonals - the diagonal passage was creating some confusing situations with ways that people commonly use wires, so I'm hoping that this is a good middle-ground · Added a V key to Vomit, which currently causes all of the materials in your stom… | — | |
| Multitool, Upgrade Pinning, and more!!! (1.0.15) The Multitool is now in the game! This tool, available after the Crowbar, combines the functions of Hammer and Crowbar into one for extra-fast building! A lot of people have asked for this, and it's finally here. :) Pinned Upgrades are also here! Hold Shift on any of the next available-to-purchase Upgrades in the tree, and you can click on the Pin icon on their tooltip to add them to the upper-… | — | |
| Toggleable Pumps! :) Just a quick update to add a long-requested feature: Toggleable Pumps! These give you a lot more control over how you move materials between chambers. :) You could even hook them up to timers and sensors to make more precise machines. Some additional things in this build: · BUGFIX: Brass and Barite now have weights · BUGFIX: Crowbar should now break any build pixel at any hardness; walls genera… | — | |
| Cow Update! This update adds some new things related to cows! Cows now actually eat grass. After eating 6 pixels of grass (max 2 per bite), they will poop. The Cow manure reacts with Soil to create Loam. There is also a new craftable Cowbell pixel in the Extra pixels category. The Cowbell is a signal-activatable pixel that causes any nearby Cows to produce Milk if they are ready (there is a one minute cool… | — | |
| Lots of Hotfixes!!! This build adds a LOT of hotfixes and quality-of-life improvements! · BUGFIX: gases no longer condense when in space (only when in the atmosphere) · BUGFIX: fixed a logic issue with how the maxed-all-friendships achievement was awarded in the demo, where you could trigger it early by accessing full-game npcs (now only responds to the demo npc friendship levels) · BUGFIX: the new Help and Feedba… | — | |
| Four more languages! Also Hotfixes... We've got a new update out! This one adds four more languages to the localization settings: Finnish, Romanian, Norwegian, and Greek! And also, a bunch of fixes! Things in this build: · Added new languages: Finnish, Romanian, Norwegian, and Greek! · Made the Vanadium Carbide Steel reaction easier by removing the requirement for all 8 cells around the Vanadium Carbide to be filled - now it's fine… | — | |
| Cow Respawning Fixed :) The cows and chickens will now properly respawn where you're placed them, so you can start creating automatic farms. :) They still sometimes fall through single width floors though, so I'd recommend making them at least double-width for now, until I have a chance to revisit collision. A lot of people have been asking for this, so even though there are just a few things in this build, I wanted t… | — | |
| Hotfixes! Just a bunch of minor hotfixes and quality-of-life things tonight: · BUGFIX: made the "Did You Know" tip carousel in F1 help not render over the individual help pages · BUGFIX: made dropping materials with the Hand tool respect static walls (not drop in area outside of what is contiguous with the unblocked area around the exact mouse target) · BUGFIX: parentheses now render properly around ions… | — | |
| Building Improvements! This update adds a lot of long-asked-for improvements to building! Hammer Tool Improvements: · The Hammer Tool can now cycle through: line, empty rectangle, filled rectangle, empty oval, filled oval. · The Hammer Tool can have the spacing between dots set from 1-4 · Hammer UI has been simplified with toggle buttons that cycle through states Programmable Pixel Improvements: · The Cooling Pixel c… | — |
