| ## Framer Prototyping | ||
| For a complete overview, downloads and docs please visit [framerjs.com](http://www.framerjs.com). Find the latest builds at [builds.framerjs.com](http://builds.framerjs.com) | ||
| #### Building | ||
| - Download or clone the code | ||
| - Run `npm install` to get the dependencies | ||
| - Run `make build` to build the latest version | ||
| #### Testing | ||
| - Run `make test` to run the unit tests in phantomjs | ||
| - Run `make safari` to run the tests in Safari | ||
| - Download Cactus and open extras/CactusFramer, then go to /test.html for a list of visual tests. | ||
| #### Reporting Issues | ||
| - Please use the issue tracker and tag them with Framer3 | ||
| - Try to include an example and clearly describe expected behaviour | ||
| [](https://app.wercker.com/project/bykey/8e5d02248bfd387acebdf177fba5f6b1) | ||
| ## Framer 3 Changes | ||
| Framer 3 is close to a rewrite. Or maybe more a huge refactor. The new code base is simpler and very well tested, so I hope others can start contributing more easily. | ||
| #### New Features | ||
| - State machine | ||
| - A proper way to organize animations | ||
| - Define a set of states with myLayer.states.add "name", {properties...} | ||
| - Transform to a specific state with myLayer.states.switch "name" or myLayer.states.next() | ||
| - Optionally override layer.states.animationOptions, or pass them in | ||
| - Animation backend | ||
| - Based on requestAnimationFrame | ||
| - Allows for more precise animation handling and better control | ||
| - Allows to change animations in-flight, which is required for real physics | ||
| - Animations now take a new argument curveOptions that can contain named inputs (like spring, tension, velocity) rather than the old curve "spring(x,y,z)" argument. | ||
| - Animators | ||
| - Added damping harmonic oscillator spring physics (curve: "spring-dho") | ||
| - Very simple infrastructure to add your own animators: | ||
| - Emit a number on a tick | ||
| - Check if the animation has reached it's end | ||
| - Support for future advanced animators like real physics and path animators | ||
| #### Big Changes | ||
| - Views are now called Layers (superLayer, subLayers, etc) | ||
| - Layers get a default background color and width, height on default so you can see them | ||
| - You can override the defaults yourself like Framer.Defaults.Layer.width = 100 | ||
| - Layer events (myLayer.on) have a modified scope where this is the layer it's being called on | ||
| - There is no ScrollLayer, it's just a Layer. You can enable scrolling with scroll, scrollX, scrollY (and animate them). | ||
| - There is no ImageLayer, it's just a Layer. Set the image with myLayer.image = "url" | ||
| #### Smaller Changes | ||
| - More sane error checking all around, throwing sensible errors if you do something wrong | ||
| - Transform origin are now full properties: Layer.originX, Layer.originY | ||
| - Most objects have a nice .toString() method for debugging | ||
| - Added delay and repeat keywords to animation | ||
| - Animation events now also get emitted on the layer (start, stop, end) | ||
| - Replaces the Underscore library with Lodash and added Underscore.String | ||
| - Some css properties are now directly exposed on the layer (without having to go through .style) like backgroundColor | ||
| - Added Utils.mapRange to map from one number range to another. So 0.5 as input from 0-1 to 0-50 becomes 25. | ||
| #### Big bugs fixed | ||
| - A lot of stuff around animations | ||
| - Reliable event handling (start, stop, end) | ||
| - Multiple animations for one layer | ||
| - Rotation issues beyond 360 degrees | ||
| - Rewritten the Photoshop importer with tests | ||
| #### Backwards Compatibility | ||
| - View, ScrollView and ImageView should work, but they give a warning. | ||
| - Animation spring initial velocity behaves a bit different | ||
| #### Known Issues | ||
| - Rotation issues with a low z-index cause drawing issues. | ||
| - Animation perf in some versions of Chrome seems less good than Framer 2 (maybe fixed) | ||
| - The blur (and likely other filter properties) are kind of broken on Chrome | ||
| #### Plans | ||
| - Add back in the css keyframe animation backend and allow to switch between them on a per animation basis. | ||
| - Add more animatable properties. You can set layer.style as an animation target and animate it's numeric css properties. - We'll have to put some converters in to tween between colors, gradients, shadows, etc. | ||
| - Add back in the box2d physics engine and come up with a testable api | ||
| - Research FF/IE support | ||
| #### Framer 3 Release Todo | ||
| - Add a Framer.Future namespace to try new stuff | ||
