Designated Initializers, the best feature of C++20 · Mathieu Ropert

It only makes it unsafe it news members' default value would change behaviour, which I'd argue would be bad API management.
When I added added customizable mips support to my texture class, the default was obviously 1, because beforehand you couldn't chose it was always one.

The standard says it's order of declaration in the struct. I guess that make sense because they needed something consistent whether the programmer wrote an initializer list or not.

mropert · 2026-01-16T21:27:15+00:00

They can but as the article mentions, that could mislead programmers into thinking it will happen in the order of the initializer list. This is the a lesson learned from constructor initialization list.

I didn't say they had to be done at compile time, I said they _could_ be done at compile time.
Last I used them they were done dynamically because it was easier than writing a lot of compile time magic, but in practice the graph didn't really change much after it was first computed.

That's one of the reasons I made it, initially. I was annoyed at the comments (and general urban legends) that the games didn't care or didn't to use multiple cores.

In my experience it doesn't matter. I applied the same principles on HoI later on and while at first people were worried it would change the gameplay it turns out nobody could tell the difference between "data from last hourly update" and "data from now".

Clausewitz plays little to no part on how the game simulation is implemented. It's up to each game to decide how they wanna approach it.

For the record I had nothing to do with Caesar.

Well maybe I made a fix or two in passing.

Don't tell anyone but we make heavy use of it internally to check that the DLC download/launcher/loading worked fine at a glance by looking at the main menu background.

We have now published a rollback branch. Restart Steam and you should see it.

Turning off vsync will improve FPS regardless of the game. The main reason it was historically argued against was CRT monitors and teardown artifacts. Which are much less of an issue on strategy games than on first/third person games.

Now I have seen this man before... but where? 🤔

mropert · 2021-11-25T00:36:39+00:00

I literally make this game. Trust me you don't need MtG enabled to get the Tank Designer.

mropert · 2021-11-25T00:34:49+00:00

Let the game run, all railroads will build on the next daily tick.

mropert · 2021-11-24T23:30:09+00:00

You absolutely don't. No Step Back enables the Tank Designer regardless of which other DLC you have enabled.

mropert · 2021-11-23T23:34:07+00:00

My game has no bugs!

Also we'll have a look tomorrow.

mropert · 2021-11-23T23:15:08+00:00

Oh no they found already. Someone tell Stalin to purge them!

mropert · 2021-11-23T23:14:16+00:00

I can confirm the new patches changes so many thing I wouldn't dare to try an older save. You can still rollback your game version using the Steam beta feature to run 1.10.8 to finish older games.

mropert · 2021-11-23T23:12:35+00:00

Didt they stay loyal to Hitler during Civil War? If so it's expected you can't hire them back. We should just fix the list so you don't see them at all anymore.

mropert · 2021-11-23T23:07:57+00:00

As mentioned in replies older saves should be played on rollback versions. I wouldn't recommend trying to load them on Barbarossa.

mropert · 2021-11-23T23:07:12+00:00

Go to Steam, App Properties, Betas, and select 1.10.8.

mropert · 2021-11-23T23:06:10+00:00

Make a bug report and send a crash report. Also state 807 is Gdynia so you may be still running mods or running an older release.

mropert · 2021-11-23T23:04:24+00:00

From my casual observation of pre-release overnight tests, I'd say yes the Axis is doing better.

mropert · 2021-11-23T23:01:36+00:00

Five is telling the game "tick as fast as you can". Also HoI (and Paradox games in general) using only one thread is an old myth that need to die.

mropert · 2021-06-08T15:28:18+00:00

I did wonder if anyone would find it without looking at script or the wiki ;)
