exercise 33 is broken

[tadjik1]

there is a problem with contactPoint event object — there are no offsetX and offsetY properties.

This is the case only in firefox. I got affected by this too, but it works correctly in Chromium. This seems to be not easily fixable: http://stackoverflow.com/questions/12704686/html5-with-jquery-e-offsetx-is-undefined-in-firefox http://stackoverflow.com/questions/11334452/event-offsetx-in-firefox

I'm using Chrome and the results of exercise 33 is no different than exercise 32. No matter where the contact point is, the sprint still places itself so the mouse arrow is at the top left-hand corner. I clicked "Show Answer" before I ran it.

Is this a different issue? Am I the only one experiencing this?

@gabrielkunkel I see the issue on Firefox but not on Chrome. You may want to refresh the page and run the exercise again in Chrome to discard any stale state in the application.

@gabrielkunkel PR #130 has a fix for that

[morenoh149]

fixed by https://github.com/ReactiveX/learnrx/pull/130

It is possible the original problem is still unresolved, #130 only fixed the issue later mentioned by @gabrielkunkel

When I run the answer (in chrome), the sprite disappears from the screen if I drag it
