Only 90's kids remember... well not really, but these beloved effects that would follow your mouse around will always be classic reminders of the old, beloved internet.

Overview

90's Cursor Effects

"Knowing the codes" used to be all the rage, I want to bring a few back.

A repo of the old effects that inspired creativity and the desire to learn at least a little code around the world. Modernised so they're a little more efficient, and just as annoying (and twice as fun) as they were before. Have a play here.

How to Use

For the most part these scripts are plug and play.

Include the script in your HTML...

<script src="your/path/to/ghostCursor.js"></script>

And then create a new instance of its type in your JavaScript. The script will create the canvas that is used, so nothing else is really needed.

new ghostCursor();

You can also target specific elements, to have the canvas appear inside those, for example:

const targetElement = document.querySelector("#ghost")
new ghostCursor({element: targetElement});

Specific Customization

A few of these have custom options as well (if you are interested in more options, opening an issue or PR is the way to go).

springyEmojiCursor

You can change the emoji in springyEmojiCursor's emoji with the emoji a single string emoji.

new springyEmojiCursor({emoji: "πŸ€·β€β™‚οΈ"});

fairyDustCursor

You can change the emoji in fairyDustCursor's colors with the colors option (an array of colors)

new fairyDustCursor({colors: ["#ff0000", "#00ff00", "#0000ff"]});

emojiCursor

You can change the emoji in emojiCursor's emoji with the emoji option (a list of emoji)

new emojiCursor({emoji: ["πŸ”₯", "🐬", "πŸ¦†"]});

NPM

I haven't got around to it yet, but if you'd like to make a rollup that compiles everything all nice, be my guest... otherwise I'll get to it eventually!

License

MIT af, but if you're using the scripts a GitHub sponsorship or shouting me a coffee would always be appreciated :)

  • Adding to a squarespace site, X and Y coordinates not being picked up correct or offset or something

    Adding to a squarespace site, X and Y coordinates not being picked up correct or offset or something

    https://codepen.io/tholman/pen/rxJpdQ Trying to add this to a friends website for them but having a bit of trouble with alignment

    document.body.appendChild(this.element);

    Throws all the emojis to the bottom of the page and none show over the content only below, I think this is because of a clear fix.

    If Insert it in a div above the clearfix , the x and y coordinates are all slightly off.

    Any help would be appreciated

    Following Dot custom color

    I had the pleasure of implementing the trailing effect for one of our internal demos for a product and i got asked the following question so often : 'is it possible to change the color of the dot ?' , so i decided to make it happen lol . I added a couple of lines to make custom colors possible for the following dot . Cheers ,ZTF

  • Respect prefers-reduced-motion setting

    Respect prefers-reduced-motion setting

    Fixes #26

    Extremely copy-pastey, but it seems like each cursor is its own encapsulated thing so it seemed like the thing to do.

    • check prefers-reduced-motion when we init the cursor trail
    • when the value of prefers-reduced-motion changes, either re-init or destroy the cursor trail
    • add an id to the trail's canvas element, so that we can remove it from the DOM where necessary (this may help with #33?)

  • Toggle Cursor effects

    Toggle Cursor effects

    I'm wondering if there is a way to toggle the cursor on and off. I like the clock cursor, brings some retro early 00s flair, but it also interfers with reading websites. I have a event listening for mousemove and if the main tag is in the :hover query selector results I would like to turn off the cursor.

  • FIrefox 82.0a1. Cursor Effects using emojis are broken because weird BoundingBoxes

    FIrefox 82.0a1. Cursor Effects using emojis are broken because weird BoundingBoxes

    For snowFlake, emoji, and springyEmoji the drawImage call fails. This is because the TextMetrics returned from measureText have bounding box values that add to zero.

    TextMetrics
        actualBoundingBoxAscent: -3.843
        actualBoundingBoxDescent: 3.843
        actualBoundingBoxLeft: 10.5
        actualBoundingBoxRight: -10.5
        width: 21
    
          let measurements = context.measureText(emoji);
          let bgCanvas = document.createElement("canvas");
          let bgContext = bgCanvas.getContext("2d");
    
          bgCanvas.width = measurements.width;
          bgCanvas.height =
            measurements.actualBoundingBoxAscent +
            measurements.actualBoundingBoxDescent;
    
          bgContext.textAlign = "center";
          bgContext.font = "21px serif";
          bgContext.textBaseline = "middle";
          bgContext.fillText(
            emoji,
            bgCanvas.width / 2,
            measurements.actualBoundingBoxAscent
          );
    

    The easier fix I found is just using the height for the width, but no idea how other browser would take that. The ghostCursor is also broke for me, but I wasn't able to find out why.

  • Too many particles are created when Chrome DevTools is opened

    Too many particles are created when Chrome DevTools is opened

    Hey I figured out, that if you open Chromes DevTools on a site, where your particle code is applied, there are too many particles being created.

    I dont know why it happens but it does. Although it is not really a dealbreaker I thought that you may be interested in taking a look at it.

    z-index too low

    The canvas element has no z-index, so the mouse cursor goes below some elements of the page.

    You should apply z-index:2147483647; to it or make it configurable.

  • how about using typescript

    how about using typescript

    Interesting library!

    Hello, I am a heavy user of typescript, and i found that this library doesn't have ts support (neither written in ts, nor seems to have a type declaration package like @types/xxx).

    I'd love to do the work, rewrite this interesting library into ts to provide better type support, and I'll do it and issue a pr this week if you're up to it

    Some developers don't like seeing ts, so I want to ask your opinion here first.

  • Make Framerate independent

    Make Framerate independent

    Not sure I got everyone perfect but, the effects assumes 60fps. At least in Chrome on M1 Macs they run at 120fps so all the effects run too fast (unless that was the intent)

    One thing I didn't fix, at 120fps, effects that spawn particles spawn twice as many particles.

    Note: normally I'd compute deltaTime in seconds as in

    const deltaTime = (time - lastTime) / 1000
    

    But, all the calculations in the code assumed 60 fps so it seemed easier to pass in a 60fps clock, meaning, if the frame rate is 60fps then deltaTime will equal 1.0 and all the calculations will be the same. If fthe frame rate is 120fps then deltaTime will equal 0.5. If the frame rate is 30fps then deltaTime will equal 2.0.

    As for the limit, if the user changes tabs then requestAnimationFrame stop firing. When you get back deltaTime might be giant which could break calculations so the code limits the framerate to 10fps. Below that things will always run at 10fps. This is also useful for debugging because otherwise, stepping through the code, deltaTime would be giant.

  • Linux cursor does not match the default image

    Linux cursor does not match the default image

    I'm not sure if this is something that is possible to fix, but on different desktop environments the cursor looks different, and thus the static data string in the ghost and trailing cursors does not match.

    different default cursor example

    I haven't heard of any API or similar that can detect what the user's cursor looks like and duplicate into a datastring that you can use, but I wanted to open this in case anybody out there has and could recommend it.
