Online notes and tables for Gamemasters
GMScreen supports multiple screens, which you can switch out at will.
Have a weekly Shadowrun game? Add a screen for it. Running a D&D one-shot? Add a screen for it (and remove it when it's over, if you want).
You could even get more granular – Add a screen for each session and you'll be able to quickly reference the grappling (or explosion) rules when you need to.
When editing an item, use roll(dice, flags). Here's what that all means:
flags let you modify how the dice work. It's any combination of the following:
t{number} – this will base the total on a "threshold" number. It will count the number of dice that came up with a result of {number} or better.
roll(5d6, t5) might output 3 if the dice came up 4, 5, 3, 6, 5
Once a die has been rolled, you'll only see the output when you try to edit that item again.
Quick-and-easy hotkeys mean you can add new screens and windows with a couple keystrokes.
Hotkeys are active any time there's not an input window showing, and any time you're not typing in a text input
All your screens, windows, and data will be saved across sessions. This is browser-specific, though. If you switch to a different computer, or a different browser, you won't see the same screens.
Change the look and feel of GMScreen on a per-screen basis. Want a different feel for your D&D game, your World of Darkness game, and your Shadowrun game? Go for it.
A lot of times, when I'm running a game, I have a computer there for notes and record-keeping anyway. This is a custom-made tool to help out with that.
In addition, it takes care of some of the tedious parts of GMing that I've come across. In particular, keeping track of initiative and combat order has always been a pain. But with the editable, sortable tables in GMScreen, it's simple.
A GM screen (or DM screen) is a piece of cardboard used by pencil-and-paper gamemasters (or dungeon masters, or storytellers, or what-have-you) to hide information from players. Usually, a GM screen also has system-specific tables and charts on one side.
This is experimental code. It has not been heavily tested, and some features may not work correctly in all browsers.
Here are the browsers I've done some testing in:
