Zero-K v1.8.9.1 - Control Cleanup and Idle Improvement

A few tweaks to help new players ballooned into several major efforts aimed at improving the new player experience. As is often the case, I couldn't add a piece of UI without making it extra smart and configurable, so the result is a cleaner and more powerful interface for everyone. Once you see the cleaner command panel you won't want to go back to the full messy version, although you may want to go into the settings to unhide your favourite advanced unit states.

In other news I (GoogleFrog, writing this) have a Patreon. It is new, since the last release, and the aim is to free up a bit more time to support Zero-K.

The map above is a new version of Twin Lakes Park by TheMooseIsLoose.

Idle Behaviour

Idle units now give up and return to their old location if they move too far while chasing enemies (previously they could be baited across the whole map). This can be disabled by setting a unit to Roam. Raiders and riots are also a bit smarter about how they react to enemies while idle.
  • Idle raiders move to stay out of range when approached by riots or most other raiders.
  • Idle riots perform similar behaviour against skirmishers and against riots with greater range.
  • Units that have been pushed back in this manner only move a short distance. When pushed too far they will turn and attack.
While some attempt was made to generate good chase and push distances, there are around 1002 unit matchups so the configuration is a little rough. Expect tweaks and improvements in future patches.

Also, drones now return to their host if they stray too far away.

Command Panel

The command panel has a simple mode so as to not overwhelm new players with esoteric commands. I liked it so much that I added configuration options, to give even those that was a few more commands a nice clean panel.
  • Replaced the icons for Repeat, Movestate and Firestate.
  • Command and state position/ordering is now stable and consistent.
  • Simple mode has slightly larger state toggles, large enough to show hotkeys. The old size can be enabled under Settings/HUD Panels/Command Panel (with Simple Settings disabled).
  • Dual-toggle Hold Fire and Hold Position states replace Movestate and Firestate by default. Under the hood they toggle Hold Fire/Fire At Will and Hold Position/Maneuver. The full triple-toggle states can be enabled under Settings/Interface/Commands.
  • Added the hotkey 'H' to toggle movestate.
  • Approximately one third of the states and command are now hidden by default. The visibility of each command or state can be toggled under Settings/Interface/Commands.
  • The position and order of the commands/states cannot be configured ingame. This requires a local configuration file found here.

Camera Controls

Many games have save/recall camera hotkeys, and it is an easy enough widget to write, so there was no reason not to add it.
  • Added bindable camera save/recall position hotkeys, and more control over alerts and transition times. These can be bound under Hotkeys/Camera/Camera Position Hotkeys.
  • Added the option to remove most advanced features from Combo Overhead/Free Camera, which can be enabled and configured under Settings/Camera with Simple Settings disabled. It can now be made to ignore shift, ctrl or alt, and can be permanent set to a particular tilt.

First Game Guide

There is now an interactive ingame guide that appears in your first non-campaign game. It is enabled by default to catch those who might need it. Experienced players can simply disable it with the X, and it can be enabled via Help.

Additional Improvements

  • Added Scalpel to Fencer unit AI.
  • In the lobby, watching a game or playing singleplayer no longer removes you from matchmaking queues.
  • Command queue transparency can be configured in the main menu under Settings -> Game.
  • The main menu settings menu now informs people that most settings only take effect upon entering the next game.
  • Improved metal and energy image extended economy tooltips.
  • Area Mex now queues one Solar with ctrl held, two with alt, and four with ctrl+alt. Previously it would queue four with ctrl.
  • Missile Silo no longer repeatably fires with repeat enabled. This frees up repeat to be used to loop the build queue. An attack command may be repeated by issuing it with ctrl held.
  • Added an experimental overlay that summarises visible reclaim. It can be enabled with 'Toggle Field Summary' under Settings/Interface/Reclaim Highlight (with Simple Settings disabled).
  • Added selection hotkey settings for Swift, Thunderbird and Athena. They can be set under Hotkeys/Selection.
  • Improved a few tooltips so that they are more descriptive. Move suggests line move. Reclaim/Repair suggests area reclaim/repair.
  • Added more icons for the menu entries.


  • Fixed command tooltips defaulting to those set by the engine instead of being overridden.
  • Added startboxes for Supreme Crossing.
  • Fixed terraform height presets being unable to make walls around structures with ctrl held.
  • Terraform structure height no longer lets you try to make land-only structures underwater.
  • Fix factory plate UI on unit transfer within team.
  • Added Construction Plates to the cheat sheet unit spawner.
  • Fixed Merlin firing issues with save/load and improved walk animation.
  • Removed Misc Priority from units with shields that do not drain energy.
  • Optimised the defence range indicator.
  • Optimised the metal spot visualiser.
  • Fixed a performance issue in a piece of code that was meant to be disabled.
  • Fixed a bug with Zenith.
  • Fixed some incorrectly displayed rank icons in the extended player list.
  • Removed Dante lookahead as it seems to interact poorly with multiple weapons.
  • Dual wielding commanders now prefer to aim with their shorter ranged weapon.
  • Fixed a chicken spire error caused by there being no burrows.
  • Fixed a minor bug with AFK sharing.
  • Fixed Gauss localisation.

GoogleFrog has a Patreon

Since receiving intermittent nudges from a few people, I now have a Patreon page. The primary goal is to gain more time to develop Zero-K, however I don't want support to simply go towards "business as usual". If people support me then I should spent at least some of my extra time on tasks that are important but not necessarily the most exciting. To this end, I have decided to put more of a focus on testing and reviewing contributions from the community. A contributor who receives faster and better feedback is more likely to fall deeper into development, strengthening the project. If you like and can support this goal, or just want to support me doing Zero-K development, then I'd appreciate it.

Zero-K v1.8.8.2 - Construction Plates and Archer Rework

Some players like parallel build queues, some want more ways to optimise production, and some just think a base with lots of factories looks cool. All these desires are satisfied in this update with the introduction of construction plates - efficient mini-factories that must be placed near a main factory to function. They can be used in the campaign and teamgames to take advantage of allied tech, while in 1v1 they should make it easier for factories access their heavy units.

The rest of the update focuses on the balance of three area; Kodachi, Amph, and dense team games. Kodachi has received nerfs to rein in the range bestowed by the fire prediction AI from v1.8.5.0. Archer takes over the role of sea riot from Scallop, with Archer gaining a sonic blaster and Scallop losing torpedo power. Funnelweb, Lance, Gauss and Big Bertha have various nerfs to open up the options in dense team games.

In other news, there is a 1v1 tournament this weekend. Click here for details and post to sign up: https://zero-k.info/Forum/Thread/31918
