I admit I checked the spelling of that.

Since I was thinking about damage interception events, here's a quick cache:

using System;
using System.Collections.Generic;

namespace Caches
{
    public struct UndefinedLoan<TInstance> : IDisposable
        where TInstance : class, new()
    {
        TInstance Instance { get; }

        public UndefinedLoan(TInstance instance) { Instance = instance; }
        public void Dispose() { UndefinedCache<TInstance>.Put(Instance); }
    }

    public static class UndefinedCache<TInstance>
        where TInstance : class, new()
    {
        readonly static Stack<TInstance> _cache = new Stack<TInstance>();

        public static TInstance Take() => _cache.Count > 0 ? _cache.Pop() : new TInstance();
        public static void Put(TInstance instance) { _cache.Push(instance); }
        public static UndefinedLoan<TInstance> Borrow() => new UndefinedLoan<TInstance>(Take());
    }
}

using (var loan = UndefinedCache<Class>.Borrow())
{
    var instance = loan.Instance;
    instance.Value = value;
    ClassModifiers?.Invoke(instance);
    value = instance.Value;
}

There's definitely room for improvement with classes adhering to certain interfaces though.
The current cache, as the name implies, doesn't give out instances with known contents, which is quite ugly in this environment.

[editline]edit[/editline] It's also not thread-safe, but you can fix that by using a [I]ConcurrentBag<>[/I] instead.

So I've got a career fair coming up on the 14th, and want to have some real progress to show on my interpreter by then. I'm doing it in C, but from what my therapists (you guys) tell me, C# is the way to go. So I was wondering if it would be feasible to compromise and write my server in C# while the interpreter is in C? Also is an interpreter/web server the kind of thing that would impress a recruiter at a community college job fair? I'm 2nd year student

Fun fact: one can rename *.exe to *.bat and it would still execute just fine.

I'm like 99% sure that if an .exe file and a .bat file are both handled by the same process (windows' runtime), then the extension actually does nothing. Extensions are naming conventions and do not change the file in any way. In Linux, what really tells the OS about the file is generally the first 3 bytes which are usually ascii for the filetype. However, changing the name can mess up other processes which refer to it by a specific name. Idk if any of this applies to windows though

I'm working on a better way to handle attack data and attacks in general for my 2d game.

All playable characters are derived from BorealPlayerBase, and that class will a function that performs attacks from the data found in the files, and then code for handling which attack to execute (weak and powerful normal attacks for example, are universal), from that class I will create BorealPrincess and BorealKnight, in the case of BorealPrincess you can perform special attacks, which can then be handled sepearately, but without having to rewrite too much code, just find out what attack the user is trying to do, read it from file and call the attack function.

{
	"name": "grAtkN_w",
	"type": "melee",
	"damage": 10.0,
	"cancels": [
		"grSpAtkU_s"
	]
}

The game already knows where to find the collision data and attack data based on the attack name, in this case "grAtk_w" (ground attack neutral weak), which would be found in "/Characters/Princess/Attacks/grAtk_w", then the game will figure out it's a melee attack and simply set the current animation and collision data to the correct one, if it was a projectile you would need to supply the projectile name class, and it would perform the animation and then spawn the projectile at the given time, the cancels part contains the names of what attacks can this attack be cancelled into, so if you are performing grAtk_w you can cancel into grSpAtkU_s

I don't have code done, just diagrams because UE4 decided to fuck itself last night, but heh, I also don't know if this is the best way to handle this, but I think it's the most flexible one.

I got a band-pass filter working with the help of some algorithms found on Stack Overflow.

Here's a spectogram of white noise filtered to 1000Hz-2000Hz:

This hopefully will allow me to layer several clips of filtered noise to create consonants for the TTS. I'm going to try that out this week.

Neat. It looks to me like the image was sampled at several different scales using nearest-neighbor interpolation, and the results were averaged.

[QUOTE=Tamschi;48635846]Unlike an update loop or entity script this is free unless the entity is damaged, and can easily be applied as overlay to an otherwise unrelated entity.
(Technically you probably already get that latter point through mix-ins in Lua though.)[/QUOTE]

I think you're overstating the "free" part though. At least in my code, when I do something like if input:pressed('action') or if collision:enter('enemy_tag'), this check isn't really triggering any computation. The computation already happened on the background and it set some variable to true or false in this frame. I don't think having a few additional ifs per entity that basically check to see if a variable is true or false costs that much.

What's the algorithm? Are you using complex values for your audio signals?

Too pixelated IMO. You can hardly tell what is happening. It can be neat to show something for a few seconds(like some kind of transmission?), but a whole game like this would be quite painful to play.

It could use improved sound mixing (options).
Some sounds are far more quiet than others and the loud ones have noticeably different volumes too.

It depends on how much you want to scale this up and how much dynamic composition you use (which can be quite expensive if you have an active loop in every single part).

Personally I'd like to reduce the load as much as possible so that what I write works well on slower computers too without spinning up the fans too much (as long as there's no significant increase in work.
The projects I intend to use this for are complex enough to justify it and likely will be easier to implement with [I]some[/I] FRP though).

To be fair, I think a lot of that is down to bad video compression. Whatever codec was used here has not handled the shifting colours very well so it's come out pretty muddy in the video.
I'd assume it's at least a little bit clearer in person.

I am using two [URL="http://www.musicdsp.org/archive.php?classid=3#38"]Butterworth filters[/URL] in series, a low-pass and high-pass. For now I am simply randomizing the samples for noise, but I'll likely change that later in case I find that it impacts the desired quality of the output noise after filtering.
