@Bbrk24 If you want to run a command if an entity (say, a bat) exists, /execute if entity @e[type=bat] should work. The @e[] here can have the same selectors as /testfor.

Bbrk24

What about /testforblock?

Tsumiki Miniwa

If you want to count a number of entities meeting a certain condition, the best you get is either /execute as @e[...] run scoreboard [...]

Alternatively, you might be able to do /execute store [???] as @e[...] run xp add @p

For testforblock, gimme a second

Maybe /execute if block?

Honestly I don't remember testfor and testforblock very well, I'm just guessing based on what the wiki has

Based on the name, I think /execute if block [...] and /execute if blocks [...] would both work

From what I'm able to find on google, you can't run /testfor except as a command block.

Bbrk24

huh, TIL execute if

I wonder what the rules are for submissions in Minecraft that involve command blocks?

Other such questions regarding bytes:
Okx's submission required a redstone ready superflat world, but mine could be run on any world (assuming Cheats, of course).

(well, didn't mean to hit enter)

How many bytes is a datapack submission, at minimum?
(Alternatively, how hard would it be to make a "Mncrft" language that reads the code, makes a datapack, puts it onto minecraft, opens minecraft, creates a world with that datapack, and runs all of the code. And how would TIO run it?)

Bbrk24

I've seen "blytes" (# blocks + # bytes of commands)

for command block submissions

And I've seen datapack-based submissions that only count the mcfunction code and not the whole datapack per se

@TsumikiMiniwa I believe that, since the introduction of the structure block, you can export specific structures that do the task as required into saveable files, and you use the size of those files

Bbrk24

Oh interesting. Makes sense though

Tsumiki Miniwa

Ooo. Never touched the Structure block before but that could be interesting.

A: Programming in Minecraft (Redstone) - how to measure program size?

There is now an MC Standard for bytecount. With the 1.10 update, they introduced a block called the "structure block", which creates a .nbt file representing a structure in its entirety that can be measured in bytes. As this is a Minecraft standard for converting builds into bytes, this should b...

There are also functions which use .mcfunction files, and you just submit the length of that file in bytes

Bbrk24

You know that ~-x and -~x trick? Trilangle doesn't have unary negation, only bitwise complement, so I sometimes have to do that trick in reverse to negate a number.

i.e. ~(x+1) or ~x-1(which are two instructions each, )~ and ~( respectively)

@TsumikiMiniwa I don't think string concatenation is possible right now, unfortunately

I think you can do some weird stuff with a custom translations file and the JSON text formatting to output concat'd strings in various situations, but concatenating strings as data is impossible IIRC (or at least, it was as of when I was 12 and tried making a high level lang that transpiled to data packs)

What should I put in my Github bio? It's just empty right now

because I suggest taking a short quotable line and using that if you can't think of anything better :p

My chat bio, and my server bio on the discord, are a bit of a joke. My discord sever bio explains it a bit more than my chat bio here does

How do bounties work on dead accounts? I see clismique's bounty on unbounded survival-buildable redstone prime checker but I also see the last activity from @clismique was in 2021 (literally on January 1st, no less)

As an unrelated question - and since I can't ask clismique directly - what are the rules for that Minecraft bounty? Namely, the Observer block wasn't added until 1.11, which didn't officially release until a month after that bounty (although I think it existed in snapshot form before the bounty's release)

Bbrk24

@TsumikiMiniwa Depending on the bounty, someone else might offer it in their place, or you might just be out of luck

Tsumiki Miniwa

Dang.

very cool

you didn't post it yet, right?

It will probably be 2 weeks or so before I post

just curious, did you get the idea from the ted talk by hannah fry? :P

Not consciously but I have watched that talk so it probably implicitly inspired me

Huh, is there really no simple hex to decimal challenge? I was ready to commit scanf abuse

mousetail

There is decimal to hex

Bbrk24

Yeah but my language has scanf("%i") and printf("%d") builtins. There's no printf("%x") builtin

(more accurately it's printf("%d\n"), but whatever)

Q: Mapping Passing Through Point

(Inspired by this challenge.) Given six real values in three pairs: \$(x_1, x_2), (y_1, y_2),\$ and \$(x_0, y_0)\$, where \$x_1 < x_0 < x_2\$ and \$y_1 < y_0 < y_2\$, create a function which maps between \$(x_1, x_2)\$ and \$(y_1, y_2)\$ which also passes through \$(x_0,y_0)\$. In other words, m...

Does codegolf.stackexchange.com/questions/259037/guess-the-array count as restricted-complexity?

No. Your time complexity can be whatever. I only care about how many times you ask questions

@97.100.97.109 I'd say maybe. Restricted complexity is not just for time complexity, memory complexity. It would seem there is a restriction on the question complexity.

What do you think of a fastest-code mastermind challenge

would it be interesting or a near-dupe?

Some rules will be changed, too.

Has anyone ever made something like the CLR, but for golflangs? A bytecode VM with support for heterogeneous lazy lists, user-defined classes, etc. and with a ton of common golflang functions built in

I guess you don't need a whole bytecode VM, just a C library with Python bindings or something
