Sim

This article is a stub. You can help Screeps Wiki by editing to add more information.

The simulator, often called sim, is a simulator of a screeps server that runs in your browser, on the webpage it can be found on this page by clicking survival https://screeps.com/a/#!/sim

The simulator gives you 1 room and the ability to change tickrate and spawn any structure

The following are notes gathered by the screeps community about the differences compared to playing on the official server or on a private server (TODO: insert link to private servers)

sim room differences

Comments from other players

room.controller.safeMode is not started when the sim starts like when you spawn on official or PS global resets after ~10 seconds

I'm working in sim right now. So far what I've run into is an issue with roomVisuals. I had to turn off room visuals in the graphics interface and turn it back on for it to paint them. Tick speed seems to be dependent on the graphics as well. If I zoom way out, the frame rate goes up, and tick speed seems to improve as well.

Yeah. Incidentally, on mmo roomvisuals don't work if you have particular other graphics options turned off. No idea why

I've never had any problems with visuals on sim irc, Game.cpu.getUsed() always returns 0 I also had a problem with Game.map.describeExits, because it returns what you would expect from a room completely surrounded by walls, which confused my room planner, since there were exit tiles without walls Game.cpu.bucket is undefined Well, in sim, you're limited by your browser, so I had to stop using object spread

beut. Also the simulation room seems to be messed up with structure limits at level 2 i was able to place like 16 extensions
