Ok. The variety of game objects in a strategy game is substantial. You have not only units and buildings but also projectiles, projectile explosions or impact representations etc. The question is do they all get the same treatment? I know they can’t be treated exactly the same all the way trough but I mean do they have an Update() function which is being called each frame? The only thing that has graphics changing and isn’t a game object is water animation, that must be the only item that should be treated differently, other than that it seems like everything should, on a shallow level, look the same, be in the same place and get modified using the same approach.

This is very broad, you need to break this down into way smaller chunks, design modules for each part i.e. building and line of sight, pathways and obstacles etc. etc.
Maybe follow the following link on where to start - WHERE TO START IN GAME DEVELOPMENT[^]
Quote: Many developers love games and want to build games. But game development is a vast ocean. There are so many aspects to developing a game that it's hard to understand where a game developer should even start.
One way to start building a game is by choosing how you will build it. Regardless of whether you're an indie developer or an established game development studio, there are 3 ways you can build a game.

You can't collide until something is moving. You can't move until you've "spawned". Line of sight is useless until you're "targeting" (firing or traveling to a destination). Things have a (natural) order. You're focusing on details without a bigger picture.

Context: Windows Server 2012 64 bit, everything else is 32 bit.
So, I have a very simple application using tcpip that has worked fine for years. This application exists in the structure of another var application. Using a config file, the var knows to launch my code and connect - it's the way the var allows 3rd parties to extend services. In the environment that works, the oem app and mine runs in user space (see note below). From the user application window, I launch it, everything starts, like is good. It's worked for decades.
In present time, I need to start the oem app as a service. The app starts, launches my application (app runs under a service account) where upon my app C000005s to death. No code has changed. C00005 exceptions are usually obvious to track down - look for the smoking hole in the ground. This one is a little sneaky since it's a few degrees off from my keyboard.
I have an assert and a DebugAssert athe very beginning of my application - c5s and no prompts.
If I launch my app from my command line - it starts and waits on the socket connection.
-----------------------------------------
So any ideas how to catch my app/service starting up? Can I add code to the app? My feeling is that this is system related, but well anyway

Since your application has been working fine in the user space, but encounters issues when running as a service, it's possible that there could be compatibility problems between your application and the service environment. You can try running your application in different compatibility modes (e.g., Windows XP, Windows 7) to see if it runs or not.
You can also check if your application relies on any external dependencies such as libraries, frameworks, or drivers. Make sure that these dependencies are compatible with Windows Server 2012 64-bit. Outdated or incompatible dependencies can sometimes cause unexpected crashes or exceptions.

I'll try the different modes - good suggestion. As for the dependency question, I would think if such were the case it would not work standalone. This is a *very* simple program that acts as a network connection to simulate old hardware. Trivial UI (About...) and a socket connection.
But we'll see. I just feel a forehead slapping moment coming on

Just wanted to mention that you cannot create a process with a GUI inside of session 0 where the system services resides. All window creation will fail.
Also, if you are using the old WSAAsyncSelect/ WSAAsyncGetHostByAddr and so forth... those will all fail. Make sure you aren't using any of the old "Async" winsock functions.

Excellent point, but one of the issues already identified in this migration process is that session 0 has no access to the printer interfaces. So the next step was to have the service run as a specific user.
This is where I am right now. And thank you for all the notes on WSA*, I'll check for anything like that.
Interestingly, this app is the parent of another application that seems to run just fine (same socket infrastructure).
Edited: no longer sure of the above statement.

Yeah, this is becoming an unexpected train wreck. This code was written back in Windows Xp land and possibly earlier.

If it was me I would just say it needs to keep being run as an app or it needs to be refactored. Perhaps not completely refactored but enough so you (and future developers) can have a chance at maintaining it.
I think actually I would start with the first solution - question why it needs to be run as a service.

Thinking along the same lines.
What's driving the need to do this is the 3rd party emulation system. Customer wants this system to fit into their new, super secure cloud system with network licenses, etc. Lots of requirements/desires that collide with each other.
The good side of things is that the Windows side of the code is minimal - it just provides a framework for the parts that actually do all the work. Refactoring is exactly what is going on.

Memory error.
Standard problem. The environment is different so the execution flow is different. It didn't show up before because you got lucky. Now it does. If you have a testing framework you can use a memory check library to debug.
Other than that you might also want to set it up for a delayed start. Or better if there are other dependent services make sure those are in the dependency list. The start up order is not deterministic unless explicit ordering is in place.

Yeah, I know what it means  , and clearly you are correct that the environment has changed. As I said in another comment, its sister program works fine and is nigh identical to the one misbehaving.

Recently, I have been working with C++ includes and while examining those used in LLVM, I came across several H header files that caught my attention. I noticed that they were not templated and contained both declarations and definitions with code. To my surprise, I found that these header files were included in multiple CPP source files. Although they only define classes, I am concerned that this may result in code bloat since each source file must generate the binary for each class implementation. In my own work, I prefer to place the implementation of any non-templated class in its own CPP source file and let the linker handle it. I consider this to be essential. However, since the writers of LLVM are undoubtedly more knowledgeable, experienced, clever, and intelligent than I am, I wonder if there is something that I do not understand. Thank you.

Do you mean member functions implemented inside the class definitions (they are inlined, so multiple inclusion is allowed)?

Am I misreading that? Seems like the project is focused on compilation?
Thus why would the OP ask the question in the first place?
An enterprise system will be vastly bigger than the compiler. That is going to be true for all but the very smallest of product companies. Service companies would probably always be bigger than that.
Even a system which is doing dynamic compilation as part of the business logic should still restrict that part to a very small subset of of the system, and probably a company library.
So am I just not understanding what LLVM is?

The question makes specific reference to LLVM, so I assume that is what he is concerned about. I stand ready to be corrected.

Roughly speaking adding two 32 bit numbers requires 32 Boolean gates.
Why do you need millions of transistors? I know there is also substraction, division, multiplying, comparison etc. Some operations probably require way more Boolean gates than the number of bits the numbers involved in the operation are made of.
Also my guess is there is a comparison based mathematical operation type selector that directs the bits to the correct area on the processor pill. Still it’s difficult to imagine where millions of transistors go.
If I think about it more I get it, this is just Alu. There is also non mathematical stuff that needs to be taken care of as well.
