This map is a 8-bit calculator, created entirely using entites, that is capable of addition, subtraction and multiplication.

This is another (and hopefully the last) entry in the building-machines-in-cs2d-that-no-one-asked-for series.

Unfortunately, cs2d entities without lua are (to my knowledge) not turing-complete due to a lack of variable parameters, so implementations need exponential space, which is why this is only a simple input-output calculator.





That's pretty much it. Please leave a comment if you have any questions and feel free to expand upon this project in any (non-commercial) manner you like, I'd love to hear of anything useful that actually comes from this!

Also, don't enter the memory during operations, as unexpected death may occur.

The 4K CS2D 8-bit machine (12)

That's good, because counting beyond two is too hard. (Gabe Newell struggles with it as well)

@ Mami Tomoe: That would be an incredibly difficult challenge, but it would need to be super-efficient and coded completely in lua, as you would have to emulate a full modern OS environment plus all of the hardware, so I'll pass on that one

Cant wait to run CS2D in CS2D...
