Support for mouse events about two.js HOT 10 CLOSED

I'd love this to happen. I'm going to look into tying mouse event into backbone events (never used backbone before) myself anyway though.

from two.js.

+1 for mouse and touch events. at different levels- two-level, polygon-level, vertex-level

from two.js.

Thanks for you all voicing your suggestions. It helps me prioritize what I should work on.

Until I'm able to implement something like this there are a few options:

• The SVG Renderer creates actual nodes in the dom tree. They each have an id attribute that corresponds with its two id attribute. You can bind normal dom svents to this node. See below for usage.
• Every group and polygon has a method getBoundingClientRect which can help you do hit testing.

var rect = two.makeRectangle(x, y, w, h);
rect.domElement = document.querySelector('#two-' + rect.id);
rect.domElement.addEventListener('click', doSomething);

I'm writing this on my phone, apologies for mistakes. I'll clean it up when I get to a computer.

@jonobr1 using SVG with click events sounds like a perfect workaround for now! I can live with that..

It would be a good idea to make a proof of concept and link to the prototype from the documentation..

Yep, @jankeesvw: http://jonobr1.github.io/two.js/examples/svg-events.html

@jonobr1 nice work! I think we can close this ticket!

As for handling events @bbn, I wonder if this is out-of-scope for the project. Hear me out before you shoot it down. I recently found toolkitchen/PointerEvents which looks like one great way to polyfill for handling mouse + touch events in a canonical way. However, it's not the only way. The inception of touch events has brought on a number of different styles to treat user input in the browser.

This in addition to other people discussing about using the rendering system outside of the browser's context where there are different user inputs makes me think that the library shouldn't force a style onto the developer. I do think exposing hit testing compatible with all renderers would help facilitate a developers effort in user input interaction.

Understood @jonobr1 . I guess what might be helpful would be a companion adapter for the web that would automagically glue the plumbing together. Thanks for pointing me to https://github.com/toolkitchen/PointerEvents (ha)

yep, no problem! Coincidentally someone else has already started implementing mouse events into two.js: #17
