DOOM-3 VS DOOM-3-BFG

>As an aside, I find the idea of writing game code in unmanaged C++ perplexing.

I don't know of a Carmack engine that doesn't have a benchmark facility.

The DOOM3 source is here https://github.com/id-Software/DOOM-3

There are lots of fascilities for recording and playing back demos. The author could record their own gameplay and play it back in realtime vs running timedemo (which plays back as fast as possible).

    2865: cmdSystem->AddCommand( "recordDemo", Session_RecordDemo_f, CMD_FL_SYSTEM, "records a demo" );

The probability a company uses visual scripting seems to correlate to how much they embrace parsing and reflection. Whenever someone is skeptical about the value of those things I just remind them that Doom3 has a C++ parser and reflection generator in it's original non-BFG release.

No but there are open-source engine ports, you only need the content packs (wad) to play it with those. Doom 3 is open source tho, they violated some licenses or something and released the source a couple of years ago (https://github.com/id-Software/DOOM-3)

Not familiar with other platforms but the Windows version uses DirectInput8 polling to retrieve keyboard and mouse state, as seen here.

The Bethesda representative said that they do not publish which OSS libraries they use but that they comply with any notice requirements. I admit, the claim on my side is somewhat thin, but there is one third party library (Base64.cpp) in DOOM 3 BFG that requires notice and states:

Even idTech 3 used third party components as listed in the description here: https://github.com/id-Software/DOOM-3-BFG. Newer versions of idTech use Vulkan for rendering. For that, they are basically forced to included the header files of Vulkan which are licensed under Apache 2. So it has to be mentioned somewhere.

I guess you can still write valuable software, even more complex than most people can write, with simple (03) C++. Like Doom 3: https://github.com/id-Software/DOOM-3-BFG

> What you are describing

On the other hand, I believe what you are describing is the exact meaning of FUD. In that precise order: "in C++ they have serious consequences" is fear, "There are bugs in the code--probably in your code--right now" is uncertainty, and "Some might be CVEs" is doubt.

According to https://github.com/id-Software/DOOM-3-BFG

Doom 3 was released in 2004. The engine has come to be known as "Id Tech 4", and it's open source. Written mostly in C++, looks like.

Id Tech 4 is currently Open Source (GPL licensed)

I believe doom 3 source is published on github so people can have a look for themselves if they want.

Doom 3 is a perennial favorite for "most beautiful C++ codebase" lists [0]
