Show HN: Choreographer-JS, a simple way to handle complicated animations

• fimdomeio 10y ago
  this does not work with time based animations right? A tool that would be really nice for developing time based animations would be one where you could switch easily between time and mouse movement.

    It works for any measurement! That choice is left completely up to the user. Instead of wrapping it in an event handler, you might instead set a variable for 'start time', run animations on requestAnimationFrame, and pass in the current time.

    The documentation indicates that this library doesn't really handle the events at all (which is great imo). The getting started has more info on this. https://github.com/christinecha/choreographer-js#get-started https://github.com/christinecha/choreographer-js#get-started Looks awesome!

  Just an FYI, the scroll-hacking on the home page doesn't work with arrow key or hotkey based scrolling (for example, vimium or vimperator extensions for j/k key scrolling) - obviously a small subset of users, but I know a lot of non-dev users that use arrow keys or page up/down to scroll on web pages too.

    Works with arrow keys on Chrome / OSX for me.

      I'm on the same, Chrome/OSX, but arrow keys don't work for me on that page.

        You have to click on the page first because of how focusing works in Chrome (you start with focus on the browser chrome, not page).

  This is pretty sweet using a desktop browser, but the animations can be a little choppy on mobile. Is this more because of how mobile browsers work or are there parts of the library that can be improved performance wise?
