Space Invaders from Scratch

Writing a Space Invaders clone is such a rewarding task! :)<p>Here&#x27;s mine (using Xlib): <a href="https:&#x2F;&#x2F;www.t3x.org&#x2F;xt3x&#x2F;index.html" rel="nofollow">https:&#x2F;&#x2F;www.t3x.org&#x2F;xt3x&#x2F;index.html</a>

A Javascript based one: <a href="https:&#x2F;&#x2F;codesandbox.io&#x2F;s&#x2F;2px9y0p480" rel="nofollow">https:&#x2F;&#x2F;codesandbox.io&#x2F;s&#x2F;2px9y0p480</a>

Heh - I remember doing this in ascii-art on an Osbourne CP&#x2F;M machine, first in Basic and later in Z80 assembler. I used the wiring diagram in the owner manual (!!!) to work out how to make a joystick I could plug into the parallel port. I was maybe 13 at the time...

Since everyone is showing off theirs here is my half-assed attempt: <a href="https:&#x2F;&#x2F;bitbucket.org&#x2F;kennethrapp&#x2F;spaceinvaders" rel="nofollow">https:&#x2F;&#x2F;bitbucket.org&#x2F;kennethrapp&#x2F;spaceinvaders</a>

I implemented Space Invaders from scratch, but in a roundabout way... By writing a well documented 8080a emulator that can play dumps of the arcade roms: <a href="https:&#x2F;&#x2F;github.com&#x2F;anoakie&#x2F;siemu" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;anoakie&#x2F;siemu</a>

This brings back some fond memories. I once made a 3D OpenGL clone of space invaders for a graphics course (Windows only). It made a bunch of changes and was actually playable and reasonably challenging...don&#x27;t know if it even works today<p><a href="http:&#x2F;&#x2F;www.cs.northwestern.edu&#x2F;~agupta&#x2F;_projects&#x2F;space_invaders&#x2F;index.html" rel="nofollow">http:&#x2F;&#x2F;www.cs.northwestern.edu&#x2F;~agupta&#x2F;_projects&#x2F;space_invad...</a>

If you want to be OCD about it - here&#x27;s how the original arcade game worked...<p><a href="http:&#x2F;&#x2F;www.computerarcheology.com&#x2F;Arcade&#x2F;SpaceInvaders&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.computerarcheology.com&#x2F;Arcade&#x2F;SpaceInvaders&#x2F;</a>

Here&#x27;s my version targeted for the original 8080 hardware, in C: <a href="http:&#x2F;&#x2F;8bitworkshop.com&#x2F;v2.1.1&#x2F;?platform=mw8080bw&amp;file=game2.c" rel="nofollow">http:&#x2F;&#x2F;8bitworkshop.com&#x2F;v2.1.1&#x2F;?platform=mw8080bw&amp;file=game2...</a>

Interresting, but the OpenGL setup is not necessary?

A little bit off topic, but what are the best libraries for drawing simple graphics like this? I&#x27;ve been looking into making a small graphics project and I&#x27;m not sure which is the best to use. It only needs to draw basic shapes like ellipses, or rectangles, or just specific pixels. I&#x27;ve been looking into SDL2, as that seems relatively popular and portable, but I&#x27;m curious to see if there&#x27;s any other libraries that are recommended.

&quot;From scratch&quot; made me expect something like &quot;From NAND to Tetris&quot;.<p><a href="http:&#x2F;&#x2F;www.nand2tetris.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.nand2tetris.org&#x2F;</a><p>Or Space Invaders not on modern hardware, or at least on an emulated 8-bit system.

now that unreadable shader trick might be neat and all, but since GLSL supports if statements why not use this and make it readable? There certainly won&#x27;t be any performance issues with rendering a single triangle, but I suppose people want to feel clever?<p><a href="https:&#x2F;&#x2F;rauwendaal.net&#x2F;2014&#x2F;06&#x2F;14&#x2F;rendering-a-screen-covering-triangle-in-opengl&#x2F;" rel="nofollow">https:&#x2F;&#x2F;rauwendaal.net&#x2F;2014&#x2F;06&#x2F;14&#x2F;rendering-a-screen-coverin...</a>

He seems to have skipped over the creation of the universe step at the beginning.
