So, my game is being developed in pure C++, with very limited dependencies (Mostly just pocoproject). The main goal here is portability, not performance. The code runs on multi-platform clients, as well as the server itself.  This is all headless, not graphics whatsoever. Everything is implemented, though. Menus, navigation, the game itself, online, single player, ... etc. You can essentially play the whole game with this C++ library. I added simple console bindings, so I can visually test and play the game, but haven't hooked it with a game engine yet.  I would really like to use Unity3D for the graphical part, as it kicks ass when it comes to rapidly developing graphics, but it was a hellish experience to try and marry Mono with C++, even when using SWIG. (Basically, Mono has limited C++ compatibility, but it is really annoying to work with).  Here is the problem, I am stuck between these two islands; C++ program and Unity3D. I am not very good with OS concepts, so I don't know if it's possible to fork the main process and run a local C++ server, and have the Unity game communicate using RPCs or even REST API. Performance isn't an issue, the only issue is maintainability. I need a robust and simple system that I can wrap my head around easily.  Other solutions welcome!
The title kind of says it all. Is it possible to replace C# with C++ on a game using Unity?
Is this arthropod non-intrusive and recommended to be left alive? I am in Portugal (Lisbon) at the moment, and when leaving my room late at night (12 pm ~ 04 am) I usually face about 4 of these arthropods in the corridors:    (For reference, the "line" in the image is a standard separation on the floor. This particular example of the animal is a little smaller than a nail.) They seem to have quite variable sizes and walk primarily on ground. Also, as implicit above, they seem to be active primarily during the late night. (I don't see them much often, if at all, during the morning/afternoon.) They can be quite fast, but if left unharmed do not move much. They also appear to take shelter inside the walls.  From what I searched, it seems possible that they are centipedes. I've seen sites saying that they are useful to keep other less pleasant animals at bay. My questions are: What are those animals, and should I leave them be or not? I'm using uninstall.php for my plugin to delete all the traces my plugin did to a site on uninstall (delete). I did it in a good way, but even after the deletion there are some fields in the options table:   uninstall_plugins recently_activated _site_transient_update_plugins   in these options there are multiple values from other plugins too.  How can I take care of such traces, how can I remove all those traces too?  I checked WooCommerce and found they leave no traces after there deletion, if the "delete data" checkbox is checked.  How can I do so? I want to use a very long USB cable to place a webcam in a different room. The maximum length that I found was five meters.   What is the maximum length of a USB cable? What is the maximum length achievable when using USB extension cables? Round a double to 2 decimal places I have heard that there are some Pokémon that are region specific.  Could someone please clarify which Pokémon are region specific and in which regions that they can be found in? When can an autonomous system be written using a Hamiltonian? fsck error on boot: /dev/sda6: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY I dual boot Ubuntu and Windows 7. I was browsing on FireFox in Ubuntu and all of a sudden I get some error message, so I rebooted.  Now when I try to boot into Ubuntu I get this message:  fsck from util-linux 2.26.2 /dev/sda6 contains a file system with errors, check forced. /dev/sda6: Inodes that were part of a corrupted orphan linked list found.  /dev/sda6: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.

I often want to grab the first element of an IEnumerable&lt;T&gt; in .net, and I haven't found a nice way to do it.  The best I've come up with is:  foreach(Elem e in enumerable) {   // do something with e   break; }   Yuck!  So, is there a nice way to do this? I did apt-get upgrade it never finishes at this point:  Searching for GRUB installation directory ... found: /boot/grub Searching for default file ... found: /boot/grub/default Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst Searching for splash image ... none found, skipping ...

The system does not freeze (Ctrl-Z works, I get my console back) just that that /usr/sbin/grub seems to never complete.  What should I do? Is it possible to use a MacBook Pro as a second monitor for my iMac? Both of them have a Thunderbolt port.  If not, is there any other way? I have command prompt in tcsh that shows the current working directory. The problem is that the command prompt becomes very big once I am in a deep hierarchy of folders. How do I set the command prompt to show, let's say, only the last 3 directory names? Why am I getting "No such file or directory" when I try to execute a binary? What if I accidentally run command "chmod -R" on system directories (/, /etc, ...) I accidently ran  sudo chmod 755 -R /   instead of  sudo chmod 755 -R ./   I stopped it after few seconds, but now there is some problems such as  sudo: must be setuid root   How can I revert permissions back? Differential Equations: solve the system Solve the following system:   $$dx/dt=-.2(y-2)$$ $$dy/dt=.8(x-2)$$  This is what I have so far, but I got stuck.. $$\begin{eqnarray} dx/dt&amp;=&amp;-.2y-.4\\ x'&amp;=&amp;-.2y-.4\\ x'+.4&amp;=&amp;-.2y\\ y&amp;=&amp;-x/2'-2\\ y&amp;=&amp;-x''/2-2\\ \\ dy/dt&amp;=&amp;.8(x-2)\\ dy/dt&amp;=&amp;.8x-1.6\\ y'&amp;=&amp;.8x-1.6\\ -x''-2&amp;=&amp;.8x-1.6\\ -x''&amp;=&amp;.8x+.4\\ x''+16x+.8&amp;=&amp;0 \end{eqnarray}$$  when I used the quadratic formula I got stuck. Is this correct so far? Can someone finish it off for me? tasks package: items are in two line with 4 columns and 4 items I write some choice questions into beamer frame, after some research, here is my code:  \documentclass[aspectratio=169]{beamer} \usetheme{Berkeley} \usepackage{tasks,CJK} \begin{document} \begin{CJK*}{utf8}{bsmi} \begin{frame} \transwipe 1.Which one you want to choose? \begin{tasks}[counter-format=tsk[A].,debug=true](4) \task A \task B \task C \task D \end{tasks} \end{frame} \end{CJK*} \end{document}   output with pdflatex:  But I don't want the D choice goto the second line, I want them stay in one line, what should I do? Direction arrows on a circle I would like to plot circle (or another curve) with positive direction (and show it wit arrows).

I wrote a question about blocking certain characters in passwords. It became tremendously unpopular, and it seemed like everyone wanted to rain on my parade every day.  Eventually, I "got it," agreed completely with what people were saying to me, and just wanted to withdraw my question so that my reputation didn't slide even further downhill.  Unfortunately, the system is designed such that I can't withdraw my question or redeem myself. Instead, I just get daily reputation attacks. That's a terrible system, and it needs to be changed. When playing as a spellcaster, is it valid the use of the Ready action to prepare Dispel Magic to counter a spell cast by an opponent? In the same vein, when declaring said action, do I have to specify which spell slot I will use when Readying the Dispel Magic spell? If that is the case, does this tactic nullify an opponent's spell? I get the impression that this is basically turning Dispel Magic into a spell with a casting time of &quot;1 reaction&quot;. Is my reading of the rules accurate? I have removed Windows 7 using GParted, and want my computer to boot straight into Ubuntu, but I still get the dual boot screen, how can I fix this? I'm trying to remember a cartoon tv show where the main boy, a blonde girl, and another boy capture monsters. There was something about a 'veil' between their world and the monster world, but a 'secret society' of sorts stopped the monsters from crossing, or used them to battle the people who wanted to use them for evil led by a wise old lady. I'm pretty sure they trapped monsters into pieces of jewelry or clothing.   Not so sure about this part: and they had these 'supernatural powers' that were connected to their 'aura' and they could travel from place to place with it.   (Another brown haired girl joined because she found out? There was an arc where the blonde got jealous and the monster she controlled attacked the brown haired girl?)  I can't remember much of it, but I remember in the end the 'veil' was broken and monsters flew over the city. And the main boy and the blonde girl held hands... or kissed?
