I need help naming an event. /agdg/ has failed me (most of them are failures so I should have expected this)

>Event Damaged
Called when you take damage
>Event Healed
Called when you are healed
>Event DealtDamage
Called when one of your abilities deals damage to someone
>Event ...?
Called when one of your abilities heals someone

Do you guys have any idea of how to reverse a dynamic string fast? I did it with a for, starting from the last position and going to the first position while printing, but that is not efficient enough.

>>61817694

>>61817698

C or Python

>>61817694
(nreverse "string")

>>61817693
EventTargetHealed?
EventUnitHealed?

Or just reuse EventHealed with optional target pointer?

>>61817602

>>61817693
might make sense to use the same event for you/other but it depends on how your game is designed

>>61817694
>how to reverse a string fast
Have all your code use a step size and starting position that's defined in the string type.
Set the starting position to the end and the step size to -1.
O(1) and really fast.
>what you did
If we're just supposed to output the string that's fine. If your output isn't buffered you can buffer it.

Generally text output nowadays is fast enough almost whatever you do.

>>61817693
Healer or heals
I prefer healer.
It's not worth spending time on.

>>61817693
Use a parameterized event
EventHealed(target)
Target can be any game creature including player character
Can also have an origin parameter determining what caused the event, or even an event stack showing the chain of events that led to the healing such as KeyPress->PlayerHeal(creature)->Healed(creature)

Sky's the limit m8, you can do anything you want.

Also namespace that shit for gods sake
Game.Events.{Healed(target),Damaged(target),etc...}

Ganes are asynchronous evented software. You can structure your events however you want.

If you're having trouble naming things, it's because you don't understand what you're doing. You literally lack the vocabulary needed to talk about the concepts in your game. It's time to step away from the code and study more.

This is what I ended up going with. I wanted to split the took damage and dealth damage events.

Even though they are essentially the same event, the only event I really care about is "Damaged" for things like ending a stun that breaks after X damage, or if you're afflicted with a debuff that breaks early when you take damage (like a Rogue Blind or Gouge in WoW if you're familiar with that)

>>61818234
>static typing

>>61818020
No. My language isn't publicly available at this time. I'm currently it's only user. It will stay that way until I have all the semantics I want in place.

I currently have no easy-to-use "standard library", just actual Linux system calls that can be used straight from Lisp. So I can do anything any other Linux program can do. To get a list of directory entries, I can call openat on a path and then call getdents until it returns 0 to get all the Linux directory entries.

I really have no idea why you're so fixated on this directory business. It's extremely basic.

I have recently developed massively enlarged thyroid nodules. It seems to have affected my ability to program.

Physically, there is not yet any obvious indication as to whether thyroid hormones are low or high, or neither. But I'm wondering if I'm bordering on psychotic, lately. I have pretty decently traced out ontological and epistemological underpinnings, and error control, but some of the shit recently. I don't know what's what. Kept getting segfaults, found I was referencing variables I shouldn't have. Would run a program multiple times and get different results, despite that the output should be deterministic. I can find no sign of uninitialized memory use. I would make trivial changes in one part of the program, and have it break things elsewhere, and the inverse. Unrelated things would fix everything. Program works fine when I go to sleep, is fucked when I wake up, for the same input. Implement a new subsystem, works fine. Suddenly my awareness is simply that it isn't working. Then it's working. Nothing has changed with the program at all. Can't recall what happened in between.

Machine is stable. Memory, probably, isn't bad. Program is written to different disk areas each build, and checksum checks out across builds. Low thyroid hormones can cause perceptual distortion. However it does seem like I'm being observed, and potentially myself or my environment, tampered with.

Etc. /blog. Can't get anything done.

Are you getting the same results and not understanding it?
What he's doing during pic related is opening a console (a command line interface to your shell which let's you use a textual interface to your computer.
Most actions are possible through that console.
The command 'ls' lists directory contents. If you just type ls it's listing the working directory contents. (if you type pwd, 'print working directory' you get what the working directory is right now).
If you find that you're not where you placed your helloworld.h you can navigate there using change directory 'cd'. You can type cd and then the absolute path to your directory to change the working directory to the absolute path directory.
g++ invokes a C++ compiler. As he mentioned this has nothing to do with prolog. He's just using this to verify that things are alright (dunno why he thinks this is a good check).
You don't have to understand that bit.
He then types ./helloworld which executes the executable the c++ compiler output. It should respond hello world.

Now.
I suggest not starting with prolog and instead something more popular where less experience is presumed. If you're looking to learn prolog you probably know how to operate a computer already. But not in your case.
Python and Javascript are the kinds that do expect much less of you. But I don't think you'd have trouble following that guide despite this though. You'll have to learn this stuff either way. If you have good reason to learn prolog stick to it.

Basically, the other day I had a hunch to attempt C++ coding, so I tackled google, came across a few things, and tried to copy that video.

I got to that 4:30 mark, and I wasn't able to replicate his results.

I went to my files, I didn't have anything like that in there, no "hello world" thing or whatever he was doing, I was just completely lost no matter how much I tried to understand it.

From the responses I've gotten here, apparently I jumped in a bit too deep, and I think I'll check out Python or whatever just to see if I could have a chance at understanding coding.

>>61819108
It compiles with compiler that implements standardized language.

>>61819019
Most old languages have historical cruft. The difference is that in C, most of this cruft can simply be ignored or cleanly worked around.

>>61819152
And what safety brings standardization?

>>61819194
Usually standardized languages have more than 1 implementation. Also they tend to make way more sense.

>>61819149
Usually the first program you are introduced to is a hello world. Just something super basic which prints the words "hello world", it's good for testing whether or not you have a working environment.
You should be well past that point if you're following that video. It's not an introduction to C++.

>>61819149
its because compiling c++ using raw commandline shit is way more awkward than it should be. just use dev-c++ ide, code blocks ide, or visual studio ide. they work right out of the box and you dont have to dick around with settings. it really has nothing to do with programming. rather just interfacing with your programs and os being strange.

How difficult are those things?

>>61819161
Yeah. The way you'd do it in the case of asprintf is reimplement it. The only other option would be to do all the work processing the format string to figure out the width and then not completing the process and instead use the buffer size you figured out to allocate using your allocator and then pass it as a buffer to sprintf.

And C doesn't have its format string processing modularized afaik.

The most relevant part is indentation.

Soon. I have a particular set of features I want to implement before I push it to a public repository. I somehow created a Lisp with direct access to Linux system calls. A linux/system-call function is among the few "magic" bits provided by the really simple interpreter I wrote.

I'm still ironing out the low-level interface with the system calls and the garbage collector. Once that's done the language will essentially become a powerful systems programming Lisp. I plan to go public at that point.

I want to create my own Linux user-space on top of this language. My future goal is full SystemV ABI compatibility, so that it can easily call into foreign object code.

I can touch type already but I realised I am typing incorrectly and now that this keyboard I've got has a big gap in the middle it's making it difficult as fuck to type correctly.

What good is a standard if people don't implement it, or implement it wrong? The only thing that matters is a working implementation. That is the standard. It's easier to understand too: just read the source code, or write test suites like RubySpec that implementations are expected to pass.

>it's shit

I agree, but it's a very much alive standardized shit language. Even then it takes years, decades for any kind of change to happen, while Python can just do it.

In this case, == is guaranteed not to work because a is stored in the stack and p in the heap. They'll always have different addresses, even if they're the same string.

>>61821647
The strings which are pointed-to will be in the data section, won't they?

Time Series analysis mostly.

But still, R is very "dense" in the way most people seem to write it. Even compared to Python I think I have to write 60% less to accomplish the same task.

>>61820347
Looks fine to me

>>61821685
Nope. The strings a points to will be in the data section (stack). At line 15, p is assigned uninitialized heap data. At lines 19/20, p is initialized, but it's address doesn't change.

>>61821796

syscall is perfectly good. If you're trying to call a linux syscall on windows you're fucked anyways. Windows technically has syscalls but you're supposed to use the wrapper library because syscall numbers change between updates. They're undocumented because Microsoft really, really wants you to use the wrapper library.

I also have to question why strings aren't utf-8 by default.

>>61821832
Not sure what you're asking.

>>61821866
The data segment is for globals and static variables. That's not the stack at all.

Actually, static and global variables are stored on the stack, but if they're pointers to static data, that data is stored in the data section, which is separate from the heap.

That wasn't even my comment retard

Speaking of Lisp, I kinda want to make an OS in it. But how? I see two ways:
1)implement a basic runtime for LISP in a normal way (ASM, C) and build in it from there
2)Make a very low-level cross-compiled LISP without GC and implement everything in it.
I kind of want to do it the second way, since it seems "purer", but it doesn't seem feasible as it'd lack basic LISP features and I'll have a separate language anyway for full LISP experience.

How do you know your C compiler does not define a anonymous function to avoid code repetition?

>>61822025
My Lisp (I still don't know what to call it yet) is a stand-alone program. It requires zero dependencies. Not even Libc is required. It's a C90 program, too. I could easily compile it for embedded architectures. The GC is designed to work with a configurable array as it's memory during bootstrap phase of the language; after that part I just extend the GC from within Lisp with an allocation function based on mmap. The bootstrap memory is allocated by Linux during program load time. It's just a static array. It'd be easy to make it work with some huge, fixed memory segment.

The harder part is implementing the low level hardware interface to Lisp. I relied on Linux so I could get away with a magic linux/system-call function, but with nothing below you'd need a lot more magic.

>>61822133
because the code is run through my custom preprocessor before the compiler can go full retard on the code.

>>61822101
Are you the fexprs retard from a few days ago?

dumb fag. defun defines functions into global space even though it might be inside let. define defines stuff only for the current scope.
Anyways I meant more of a there's no difference between using function and function like macro.
Of course there will be difference, the biggest one being that there will be no function in the compilation product.

>>61822206

It doesn't matter and if it did, that would be a micro-optimization that the compiler could easily do for you.

>>61825415

Ahh, I haven't learnt about compilers yet.

>>61825398
Depends if you want the variable to be scoped only to the loop. I've never bothered to look, but always figured declaring in the for loop header gave the compiler an extra hint about how that information will be used, possibly just keeping it sitting in a register for the entirety of the loop run.

Don't know. I see a lot of PHP programmers who start writing C declare a variable at the beginning and re-use it repeatedly, though. It likely only feels less efficient, while leading to more complicated, error prone, and difficult too maintain routines.

for each element "desired ops" in available ops, if desired ops equals available ops, then ... else ...

Rename desired_ops in the for loop to x and I think it will be clearer why that doesn't work. What you want is something closer to this

for x in available_ops:
  for y in desired_ops:
    if x == y:
    ....

this, blacks don't really care about women, they never fight over women

>>61825690
>fighting over women when you can just sexually enslave them with the BBC and enjoy them with all brothas at once

bet you also belive whites are the most incestuous

Fucking cuckolds.

>>61825775
aww, did someone break your hopes for happy evo afto by thinking of something else?

    for ( int i = 0; i < ROWS; putchar('\n'), i++ ) {
    for ( int j = 0; j < COLS; j++ ) {
        printf(" %c", array[i][j]);
    }
    }

Is it bad practice to put print functions with the comma operator in loops?

95% of the time these are numales larping as Africans.

What language?

>>61825931
Scheme. Although thinking about it, Cantor's pairing function won't work well.

I don't know of any pairing functions that do what I need. Fuck.

yes put that shit in the loop body

I thought it was from Gundam, but it might be from Memories (1995 film).

I feel even more lost, now. Code related:

available_ops = ['blackbeard', 'fuze', 'capitao']
desired_ops = ['twitch', 'blitz', 'fuze']

for desired_ops in available_ops:
    for available_ops in desired_ops:
        if desired_ops == available_ops:
            print(desired_ops.title() + " is in the roster.")
        else:
            print("You don't have " + desired_ops.title() + " unlocked yet.")

print("\nJUST\nFUCK\n\tMY\tSHIT\n\tUP\nREEEEEEEEEEEEEEEEEEEEEEEEEEE\n")

for available_ops in desired_ops:
    if desired_ops == available_ops:
        print(desired_ops.title() + " is in the roster.")
    else:
        print("You don't have " + desired_ops.title() + " unlocked yet.")

All that happens now is that a mass-print occurs. Blackbeard gets 10 prints, Fuze gets 4, and Capitao gets 7. I am absolutely lost.

This is how my mental map is thinking:

Here are the values you have = [....]
Here are the values you request = [....]

If you request values AND you have them, then state you have them. Otherwise, state you do not.

Alt:

If you have values and you requested them, then state you have them. Otherwise, state you do not.

i already have ropes prepared im so stressed right now and simple shit like this is not working

>>61826082

available_ops = ['blackbeard', 'fuze', 'capitao']
desired_ops = ['twitch', 'blitz', 'fuze']

for x in available_ops:
    for y in desired_ops:
        if x == y:
            print(x.title() + " is in the roster.")
        else:
            print("You don't have " + x.title() + " unlocked yet.")

print("\nJUST\nFUCK\n\tMY\tSHIT\n\tUP\nREEEEEEEEEEEEEEEEEEEEEEEEEEE\n")

for x in available_ops

Is pythonese for:
"∀x ∈ available_ops" or "For each x that's a member of available_ops"

I think I get it now, though I still don't understand why I'm getting the strange duplicate posting. I both attempted to retype this based on your advice and copy-pasted your text, and got the same result (pic related).

It states each op three times. It confirms Fuze as being in the roster once, but says he is not unlocked twice.

>>61826337
The inner-most if-else statement is executed 9 times, printing something each time. It's doing just what you've instructed it to do.

>>61826337
That's a deliberate flaw in my solution. 3 * 3 = 9. the outer loop loops 3 times. The inner loop loops 3 times. You can correct it with a couple changes and using a boolean variable.

Or you can use set operations in python:

Anyway you should learn more formally anon.

up through level 3 they never took more than a day tops. levels 4 and 5 i spent more time on to hopefully look good, and spent about 4 days per puzzle. most of it was just thinking about how to do it during real-life errands and stuff, the actual code was never more than 200loc.

oh, yes i opted to get contacted. forgot to answer that
