Matrix Effect Builder

Draw an animation or pick a ready-made effect, choose what sets it off in the game, and copy the JavaScript into SimHub. Made for 8×8 panels like the Flag Dash, and works with any size.

Draw now 0 mAPeak seen 0 mA

Rough estimate at 20 mA per colour channel. The Flag Dash limits itself to 350 mA, so anything above that just runs dimmer.

Pretend game data

Pick a moment to see what the whole profile shows then, or flip the boxes one at a time. The preview reads them the same way SimHub would.

Need a panel to run these on? The Flag Dash Compact is an 8×8 flag and gear panel made for SimHub. One USB cable, tested before it ships.

Your effects

    Click one to edit it. When two show at the same time, the one higher in this list wins. Every effect here goes into the downloaded profile.

    Type of effect

    Start from

    Colour

    Custom colour

    Click or drag to paint. The checker square is see-through: effects underneath show there. Black blocks what's underneath.

    Frames

    Text

    Small fits 2 characters on an 8×8, Big fits 1. Uses the colour you've picked. "Make it scroll" replaces your frames; Undo brings them back.

    When it shows

    Property names follow SimHub's standard game data. If one doesn't react in your game, pick the right name from SimHub's property list and use "Other property". Heads up for Assetto Corsa: there, SimHub's "Pit limiter on" actually reports being in the pit lane, so the "Pit limiter forgotten" preset can't tell the two apart on that game.

    Gear, flags and screensaver

    These use SimHub's own gear and flag items, so they go in the downloaded profile as normal SimHub items you can change later in SimHub.

    On iRacing that means on track, so they go dark in the garage and in replays. On other games it means not paused.

    In SimHub's editor each effect shows up as a custom conditional group with your effect's name on it. Drawn effects become SimHub's own hand-drawn animation, inside a brightness group, so you can keep changing them in SimHub. Items lower in SimHub's list draw on top, which is why your top effect is at the bottom there.

    4. Open its formula, make sure it's set to JavaScript, and paste the code.
      5. 
        
    5. If it hides behind the gear or a flag, move it to the other end of the list.
      6. 
      
    
      
      
    If the effect covers everything even when it should be off, wrap it in a group with SimHub's Enable content if condition, and set When it shows here to Always.
