Shoot with X or C.<br /> You start with 10 health points, and need to shoot as many baddies until they get you good!</p> <h2>Inspiration</h2> <p>Seeing great and cute entries closing Pico-1k jam was inspiring. That's when I got an idea: &quot;all things SSPR&quot; to balance this cuteness with DOOMY pointless violence and big pixels. </p> <h2>Technical details</h2> <p>In a nutshell DOOMY is a rotozoom (the effect you get when rotating and zooming an image) laid down flat and rendered with scaled sprites.</p> <h3>Setup</h3> <p>The textures, sprites, and the base of the level are rendered as a group of rectfill and text in the first 3 lines of code, with first two textures of 8x8 for the walls, then 2 baddies, and finally the base of the level.</p> <p>In the following 4 lines, the base of the level is expanded and some diagonal walls are added.</p> <p>Every &quot;thing&quot; in DOOMY goes in the β–₯ object which contains the x,y,t,w properties for the x,y position of the thing, it's texture index t and width w (nil or 1 for walls, 8 for the baddies)</p> <h3>Game loop</h3> <p>In the game loop the things in β–₯ are rotated and moved into another object, 🐱, if they are in the visibility fustrum. The baddies move erratically towards the player.</p> <p>The things in 🐱 are then sorted and rendered back to front, if one of these thing is large, it means it's a baddy and we render a shadow with an ovalfill</p> <h3>Collisions and baddies hit</h3> <p>For the collision detection, we check the distance of the last thing we drew. Blocking the way forward if it's very close.</p> <p>We check the color of the pixel under the crosshair to know if it's a baddy. If you shoot we play a noise, increase the score and respawn it at a random location. Otherwise there is a 10% chance it will shoot you with a red flash and some noise.</p> <p>You know the baddies are bad because they keep shooting you even when you're down!</p> <h3>Source code</h3> <div> <div class=scrollable_with_touch style="width:100%; max-width:800px; overflow:auto; margin-bottom:12px"> <table style="width:100%" cellspacing=0 cellpadding=0> <tr><td background=/gfx/code_bg1.png width=16><div style="width:16px;display:block"></div></td> <td background=/gfx/code_bg0.png> <div style="font-family : courier; color: #000000; display:absolute; padding-left:10px; padding-top:4px; padding-bottom:4px; "> <pre>u=.2v=1.5a=0p=0h=10β–₯={}r=rectfill f=add cls()r(0,0,15,7,13)f(β–₯,{x=3,y=4,t=24,w=8})?&quot;#%$3ᢜ9μ›ƒαΆœ8][βŒ‚&quot;,r(0,1,15,6,5),3,3 β—†=pget?&quot;β˜…%= ᢜ8🐱z}&quot;,f(β–₯,{x=4,y=5,t=16,w=8}),1,6 memcpy(0,6^13,β§—)for y=0,9,1/8do for x=0,9,1/8do if(β—†(x+32,y)!=β—†(x+31.9,y-.1))f(β–₯,{x=x;y=y;t=(x+y)%2*8})end if(y&lt;2)f(β–₯,{x=2.5+y/2;y=4-y%1+y\1*2;t=y%2*8})end function _draw()cls(1)r(0,60,127,68,5)l=rnd local 🐱,c,s,q,d,w,x,y={},cos(a)*8,sin(a)*8,64 for z in all(β–₯)do x=z.x-u y=z.y-v if(z.w)z.x-=(x/q+l()-β–ˆ)/9z.y-=(y/q+l()-β–ˆ)/9 z.u=y*c-x*s z.v=y*s+x*c if(z.v&lt;48and abs(z.u)&lt;z.v)f(🐱,z)end for i=2,#🐱 do for j=1,i do if(🐱[i].v&gt;🐱[j].v)🐱[i],🐱[j]=🐱[j],🐱[i]end end e=6-2*min(1,h)pal(6,13)for d in all(🐱)do z=80/d.v if(z&gt;4)pal() w=d.w or 1x=q+z*(d.u-w/2)y=q-z*e if(w&gt;1)ovalfill(x,y+z*9,x+z*w*.9,y+z*7,0) sspr(d.t,0,w,8,x,y,z*w+4,z*8)end b=btn()*min(1,h)a+=(b%2-b\2%2)/q if(b&amp;4&gt;0and z&lt;40)u+=c/q v+=s/q ?&quot;ᢜe⁢w⁢tdoomy&quot;,44,4 ?&quot;&hearts;&quot;..h..&quot; β˜…&quot;..p,44,119 c=β—†(q,q)w=&quot;\ai60&quot;?&quot;+&quot;,q,q if(c&gt;7and c&lt;13)then if(b&gt;15)p+=1d=β–₯[c-7]d.x=l(8)d.y=l(8)?w if(l()&lt;.1)pal(1,8,1)h=max(h-1)?w end end</pre></div></td> <td background=/gfx/code_bg1.png width=16><div style="width:16px;display:block"></div></td> </tr></table></div></div> <h3>That's all folks</h3> <p>Hope you enjoy this tiny showdown </p> https://www.lexaloffle.com/bbs/?tid=44970 https://www.lexaloffle.com/bbs/?tid=44970 Wed, 13 Oct 2021 14:55:54 UTC KATAMAR1k (PICO-1k Jam) <h1>KATAMAR1K</h1> <p>An homage to KATAMARI DAMACY for Pico8 in 1021 bytes for the #PICO1k jam</p> <p> <table><tr><td> <a href="/bbs/?pid=98507#p"> <img src="/bbs/thumbs/pico8_katamar1k-0.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=98507#p"> katamar1k</a><br><br> by <a href="/bbs/?uid=28958"> p01</a> <br><br><br> <a href="/bbs/?pid=98507#p"> [Click to Play]</a> </td></tr></table> </p> <h1>Story</h1> <p>The King of all Cosmos was naughty again.

They might be an acceptable alternative to <strong>ElectricGryphon</strong>'s super fast triangle rasterizer if you need an extra 2-400 tokens. If you don't, by all mean use his. It is the fastest one I found, and by a good margin!</p> <p><em><strong>Update 20180706</strong>: Added the possibility to switch rasterizer and turn the test triangle with the arrow keys. This allows to compare rasterizers at a normal pace. Updated EG's rasterizer to the latest he posted in the previous thread and added the one from <a href="https://www.lexaloffle.com/bbs/?pid=32574&amp;amp;tid=28077">Gryphon 3D Engine Library v2</a> only modified to use normal color() and fillp().</p> <p><strong>Update 20180708</strong>: Added a fill pattern and a toggle for the results and control wireframe.</em></p> <p>Hope this helps,</p> https://www.lexaloffle.com/bbs/?tid=31478 https://www.lexaloffle.com/bbs/?tid=31478 Wed, 04 Jul 2018 16:42:34 UTC PICO&#9834;HERO musical tweetcart <p> <table><tr><td> <a href="/bbs/?pid=53885#p"> <img src="/bbs/thumbs/pico53887.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=53885#p"> PICO&#9834;HERO musical tweetcart</a><br><br> by <a href="/bbs/?uid=28958"> p01</a> <br><br><br> <a href="/bbs/?pid=53885#p"> [Click to Play]</a> </td></tr></table> </p> <p>Hi there.
