Tell me what you think!</p> <p>Fast paced, technical slalom skiing!</p> <p>Controls:<br /> arrow keys: point the skis toward the arrow direction<br /> x: dash<br /> z: jump</p> <p>Slalom around the gates and get to the finish line as quickly as possible. Missing gates incurs a time penalty, so try to stay on track! Jump over the holes and avoid the trees.</p> <p>I'm still iterating on the polish and level design. I have already implemented ice patches that you slide across and moguls that you can jump off of, but haven't built levels around them yet. Thought I would release this a bit early to see how people react!</p> https://www.lexaloffle.com/bbs/?tid=30307 https://www.lexaloffle.com/bbs/?tid=30307 Wed, 22 Nov 2017 23:30:11 UTC Performance Test Gallery <p> <table><tr><td> <a href="/bbs/?pid=44898#p"> <img src="/bbs/thumbs/pico44897.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=44898#p"> Performance Test Gallery 1.0</a><br><br> by <a href="/bbs/?uid=11598"> stephan_gfx</a> <br><br><br> <a href="/bbs/?pid=44898#p"> [Click to Play]</a> </td></tr></table> </p> <p>Ok, it isn't pretty but sometimes you just want to know what the CPU cost of something is. I've started this cart just to see what things cost. This runs at 60fps, so if you're using a 30fps cart, you can divide the CPU cost by 2.</p> <p>Its structured to be really easy to add more tests to, if you're curious. Let me know if you have any questions!

It has a :filter() method that can filter the incoming noisy value.</p> <p>In the cart: if you click it draws lines. Green line is the input signal, yellow is the filtered signal.</p> <p>Based on stdlib.p8, built with @stevelavieties.</p> https://www.lexaloffle.com/bbs/?tid=29646 https://www.lexaloffle.com/bbs/?tid=29646 Thu, 13 Jul 2017 23:39:01 UTC Easing Gallery <p> <table><tr><td> <a href="/bbs/?pid=41657#p"> <img src="/bbs/thumbs/pico44294.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=41657#p"> Easing Gallery 0.3</a><br><br> by <a href="/bbs/?uid=11598"> stephan_gfx</a> <br><br><br> <a href="/bbs/?pid=41657#p"> [Click to Play]</a> </td></tr></table> </p> <p>Update: Added more functions, including critically damped spring and cosine interpolation. Also added the &quot;kaneda&quot; easing function visualization for fun :-). Also removed even more code so its even easier to see how it all works and add your own functions.</p> <img style="" border=0 src="https://www.lexaloffle.com/bbs/files/11598/PICO-8_244.gif" width=256 height=256 alt="" /> <p>PRs welcome!<br /> <a href="https://github.com/ssteinbach/pico8carts/blob/master/easing_gallery.p8">Easing Gallery github page</a></p> <p> <table><tr><td> <a href="/bbs/?pid=41657#p"> <img src="/bbs/thumbs/pico41893.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=41657#p"> Easing Gallery 0.2</a><br><br> by <a href="/bbs/?uid=11598"> stephan_gfx</a> <br><br><br> <a href="/bbs/?pid=41657#p"> [Click to Play]</a> </td></tr></table> </p> <p>Update: added a few more functions and removed a ton of crap from the code to make it easier to find the actual math.

Use the green blocks to push the red monsters back and squish them against the walls.</p> <img style="" border=0 src="https://www.lexaloffle.com/bbs/files/11598/PICO-8_130.gif" width=256 height=256 alt="" /> <p>If the red monsters get next to you, they'll attack you, and you'll get progressively bloodier.

See how many levels you can clear!</p> <p>Controls:<br /> arrow keys move the green blocks, you can't move yourself.</p> <img style="" border=0 src="https://www.lexaloffle.com/bbs/files/11598/PICO-8_128.gif" width=256 height=256 alt="" /> <p>Made in collaboration with <a href="https://www.lexaloffle.com/bbs/?uid=15987"> @SteveL</a></p> <p>Feedback welcome!</p> https://www.lexaloffle.com/bbs/?tid=29285 https://www.lexaloffle.com/bbs/?tid=29285 Sun, 07 May 2017 12:09:27 UTC
