Impulse — 2D Sonic the Hedgehog inspired platformer prototype (Feedback?)

Started by May 11, 2018 01:20 AM
4 comments, last by Emerald Streak 6 years, 9 months ago

Impulse is a 2D platformer inspired by classic Sonic the Hedgehog, with speedy momentum-based movement and 360-degree slopes and loop de loops.  As this is a prototype, there is one level, but it's pretty big, with lots of hidden coins to find for those who like to explore.

I created this in Unity using my own raycast engine for handling slope detection and high-speed collision. I made this mostly for practice and as a portfolio piece, but I may develop it further in the future. I'm a huge fan of the classic 2D Sonic games and their momentum-based physics!

I hope you all enjoy the game and would love to hear feedback!

You can play it in your browser on itch.io here:

I would like to play but am getting a lot of error messages in the console.

Interesting... Is the game not running for you then? And what browser are you using?

Testing it now in Chrome, I get much of same output in the console, but the game runs just fine... except I don't get the "22[Violation] 'requestAnimationFrame' handler took <N>ms" line.

Otherwise, the game runs fine even with lines like "The referenced script on this Behaviour (Game Object 'Canvas') is missing!".

If anyone else is having issues running the game, please let me know!

Using Chrome, problem is the frame rate is very low, to be unplayable.  I checked the console and then was when I saw the whole host of stuff.  Not sure what to do, this would be the first Unity plug-in I've had difficulty with.  Could be my end but...

Can someone around here give it a shot so we can determine where the problems lay? 

I think the console output is mostly unrelated to any framerate slowdown. It's mostly debug logs I left in, or complaints about certain assets being unused, which should be harmless. I'm not sure exactly how to go about optimizing the game further.

I added downloads for Windows, Mac OS X, and Linux builds of the game to the itch.io page. Testing on an older laptop, the Windows build runs much faster for me than the in-browser WebGL build (which runs a bit slower, but not unplayable). So feel free to try the downloadable version!
