This looks awesome! I remember playing line rider when I was in school!
I too remember the wasted hours... you still can too!

#22Hey, very cool. I'm working on a hobby project using Unity that also deals with rendering equations, and I'm curious, did you use LineRenderer to render the line?

#23I'm not able to change the function on the second level. The input field is not responding. Seems like a great concept!
What OS and browser are you on? Does this persist when you refresh?
OS X, Chrome 38. Now it works just fine. Didn't try refreshing the browser last time so don't know about that.

#24LOL, this game should be given to everyone who complains about how complicated math is. Should cure them in minutes :)

#25There will be an Android version? It is so addictive :)

#26Excellent. This is one of a very rare breed of games that attempts to encourage academic familiarity without ending up with extremely shallow mechanics that are more or less independent of the core topic.
My heuristic for evaluating a game for educational value is
"Is mastery of and success in the game directly proportional to understanding and comfort with the core academic proposition of the game."
This game scores brilliantly there. I hope educators learn to recognize the power of engagement in learning, and cultivate a sense of evaluating effective learning games.

#27Maybe you should consider using an arbitrary-precision math library to calculate the graph and physics rather than relying on doubles.

#28Earlier quoted context omitted.
What do you mean by bug? It's true that you can get slightly different simulations at different zoom levels due to the sampling optimizations needed to draw a new graph every frame, is this keeping you from completing the level?
The graph goes crazy. The sine is spiky, like there were too few samples or some kind of sampling aliasing. This happens in the web plugin and standalone Windows exe. It's so hard to explain, but I loved the game so much I'll download a screen recording tool to show what's going on. Will edit as soon as I get the video captured. EDIT: Downloaded the worst video capture tool but here it is: - Default state, zooming in…
Ah, I see what you mean. The problem is indeed sampling. For performance reasons the graph only plots a point every 8 pixels each frame, so if you have drastic changes that happen below that interval you get weird rendering artifacts. Unfortunately this will inevitably be the case until I can get a parser that's fast enough to sample for every pixel.

#29Maybe you should consider using an arbitrary-precision math library to calculate the graph and physics rather than relying on doubles.
The problem is actually that with my current parser (which is 3rd-party, and one of only a handful that works within my constraints) I can only sample the function about a hundred times per frame before I start to see serious drops in performance on many computers.
In the future I'd like to have a parser that's fast enough to sample at least every pixel, but until then it's going to be a little janky.

#30Insanely fascinating
