Mouse Path Recorder

A small tool to record the mouse position and get it as a JSON object.

• Start by clicking on the big rectangle and you'll see a small recording icon appear bottom left. Any mouse movement now adds to the dataset. Click again stops the recording.
• Enable "Limit Points" to record fewer points and get in a smaller dataset.
• Once recorded, you can re-play the paths with the play button.
• Edit the dataset in the text box below and save it as a file by clicking the download link.
• The load button allows you to load old datasets. If you load an image, it will become the background to allow you to trace it.
• Click the bin to delete all your work and start over.

File Format support

Currently, the generated files are pretty rudimentary, and there may be some tools for conversion in the nearer future.

The format is a main Object with paths. Each path has its running number as the key and an array of values. The array is a list of the recorded x and y values.

{
    "1": [x,y,x2,y2,x3,y3 … ],
    "2": [x,y,x2,y2,x3,y3 … ]
    …
}

Why?

Well, this is one of those "scratching your own itch" things. We're working on a demo for the Commodore 64, and needed a way to record some hand-writing to replay using sprites.

So, yeah, geek stuff.
