Changelog 2017-05-18: hard resets fix

A Node.js contributor and Screeps player Marcel Laverdet managed to track down a bug in the built-in Node.js vm module that caused a race condition when sandboxed code timed out. It was the primary reason of so called “hard resets” of player code execution in Screeps. A fix for this bug is manually patched into Node.js on Screeps runtime servers, and the number of hard resets is greatly reduced now. This change takes effect starting from now.

The patch is proposed to Node.js upstream repo. If you want it to be included to your own Node.js instance running your private Screeps server, you can give it a thumb up on GitHub. Well done Marcel!

There are still some other reasons that cause hard resets occasionally. We’re working on tracking them down right now.

Meet our Community Manager

We’d like to introduce a new team member who will be responsible for communication between the
community and the Screeps Team as a Community Manager & Advocate:

Hey everyone, let me introduce myself. My name is Mark Bertels but most of you probably know me as Dissi. I’m 27 years old and I live in The Netherlands. I have been programming for more than 12 years now. I’ve made my hobby into my profession.

I’ve been an active Screeps player for nearly 2 years now and saw that the Screeps team needed a community manager. As I really love the game and community as a whole I did what any member in the community would do; I applied for the position. Today I can tell you that I will be helping the team as a community manager! I will be helping them out in consolidating different opinions in the community on changes. I will also be tracking down bugs and helping with the requests.

As a community manager I also will be voicing your worries and ideas back to the development team.

I’m practically always online on the slack channel, you can ping me there with @dissi if you require my attention or just want to chat a bit!

Hope to see you in-game!
Regards,
Dissi

Fleetster uses Screeps to hire developers

Going to another technical interview and want to show your Screeps skills as a proof? Fleetster startup uses Screeps as a key part of their recruitment process. Anna Baumeister explains how Screeps is useful for their business:

We started using Screeps as a means of technical evaluation end of last year. Since then, our business has been thriving and our use of Screeps as a test has become more visible.

In order to understand why we chose your game as a key part of our recruitment process, it’s important to understand a little bit about fleetster. We are a small startup in Munich, Germany, working with the latest JS tech - Node, Ember, React, React-native, TypeScript etc. Our business is lean and our process is agile which means specifications are changing all the time.

Screeps is useful because it throws candidates into an unknown environment where the number of “right” solutions are very numerous. They have to get their bearings and make a pl an of action whilst dealing with unexpected outside interference (other players). We hope you won’t mind our presence in the main game world, but we find the huge scope of the main world helps to further intimidate candidates. We need people who can take on complex challenges head on and realize that most often the solutions are simple and accessible.

— Anna Baumeister, Management Assistant at fleetster

Changelog 2017-05-11

  • Updated runtime Node.js version to 7.10.0 (with V8 5.5).

  • Changed terminal transfer energy cost formula:

    energy_cost = resources_amount * (1 - Math.exp(-range / 30))
    

  • Introduced new StructureTerminal.cooldown feature. It is triggered on both StructureTerminal.send and Game.market.deal methods and is equal to 10 ticks regardless of the transaction size and range. Methods will return ERR_TIRED code if the cooldown is active. New TERMINAL_COOLDOWN constant is added.

  • Removed non-intuitive behavior of auto-attacking objects on Creep.move. This fixes an exploit of doing attack and heal simultaneously which is prohibited.

  • Runtime virtual machine now uses breakOnSigint feature. CPU limit reached error messages have three types now:

    • Script execution timed out - when the soft timeout is fired
    • Script execution has been interrupted - when SIGINT signal received
    • Script execution has been interrupted with a hard reset - when SIGKILL signal received (runtime process restart).

    These differences are mostly for informational purposes and don’t affect anything currently.

  • Changed boost effects of UO, UHO2, XUHO2 according to the documentation.

These changes are supported in private server v2.6.0.

Screeps World Review Q1 2017

Screeps has been in the process of total reorganization lately. We’ve just launched our revamped game documentation and the blog where you’re now (the new forum engine is coming). We are reorganizing our team, and 2 new members joined us: a designer and a developer (they will be introduced later). We’re rebuilding the client graphic code from scratch using the PixiJS engine to optimize performance and bring the game graphics to a completely new level of quality. And the main revamp, server-side, is expected to be announced soon. It will have to do with official game servers and will introduce a radically new approach to expansion of the game world which will help solve the issue of slow tick duration.

Unfortunately, all this reorganization work affected our Screeps World Reviews. Starting this month, they will be published quarterly. Writing them every month took the time that we now want to invest in the game development itself.

The anniversary three-digit perimeter W100N100-E100S100 was opened recently. So let’s make a snapshot of our mega-labyrinth containing over 90k creeps:

New documentation site

Great news: we've launched a new documentation site!

Quality documentation and API reference are crucial for the success of any program platform, and Screeps can well be considered a program platform. That's why we spent so much time to thoroughly document all available game objects and methods which was not very convenient on top of Zendesk Help Center. Now we are excited to announce the launch of our new documentation site that you can start using right now!


Here is the link: docs.screeps.com


Besides revamped looks and improved desktop and mobile navigation, the new site boasts another feature: it is fully open-source and GitHub-based. This means you can always offer a fix or suggestion.

And that's not all! We understand that Screeps is a game with a steep learning curve, and good documentation helps make it flatter. If you want to help us document the game well, we are ready to thank you in return.

Contribute to documentation and earn money

We announce the launch of the Contributed Articles program! If you write a fully compliant article that will be included in the official documentation, you will get $50 on your PayPal account or 5 Subscription Tokens (roughly equivalent to $ 90) on your game account depending on your choice.

Please read more about the program using this link.

Changelog 2017-03-09

Introduced new kind of world map zones: Respawn Areas.

  • Respawn Areas are highlighted with blue color on the world map.
  • They are isolated from the rest of the world with a wall. The wall has a timer similar to Novice Areas. Any player can place the first spawn in this area, but nobody can come here from the outside world while the timer is up.
  • The only restriction in Respawn Area is nukes usage - a nuke cannot be launched from or to a room in a Respawn Area.
  • Players with GCL 4 or higher are no longer able to start playing in Novice Areas. They have to either respawn in a regular room or in a room within a Respawn Area that will keep them safe for a while and allow to claim as many rooms as their GCL allows.

Other changes

  • When a Novice or Respawn Area is being planned in an inner sector, all free rooms in this sector will be signed by the game with the following message:

  • Added new constants SYSTEM_USERNAME, SIGN_NOVICE_AREA, SIGN_RESPAWN_AREA. You can use them to programmatically check the signs in the rooms that are important to you and reserve them if such a message detected.

These features are supported in private servers v2.5.0.
