Quake-III-Arena VS UnrealEngine

Quake III Arena

If you know C, you can check this out by comparing the different player movement code of Quake 3 and Quake 1.

You mean this code?

Do you see that notice at the top of the file? It says:

This file is part of Quake III Arena source code.

Quake III Arena source code is free software; you can redistribute it

The error messages comes from this file in the source code. It looks like the client is trying to parse entities from the server but the readcount is greater than the cursize in the messages. I am not an expert but I believe there could be a mismatch between the versions of your client and the servers you are trying to connect to.

After learning C, one of the first projects I came into contact with, was the ID Tech 3 game engine [1]

On the one hand, it taught me how professional C programmers structure their code (extra functions to remove platform differences, specific code which is being shared between server and client to allow smooth predictions) and how incredible fast computers can be (thousands of operations within milliseconds), but it also showed me, how the same code can result in different executions due to compiler differences (tests pass, production crashes) and how important good debugging tools are (e.g. backtraces).

To this day I am very grateful for the experience and that ID decided to release the code as open source.

Visual Studio has a related annoying habit when navigating the call stack (the caller's scope is considered closed if the callee is syntactically its tail) so I wonder whether this workaround would be useful for it as well.

See also this comment in the Unreal Engine code about putting a nop in before as well: https://github.com/EpicGames/UnrealEngine/blob/26677ca1b3c97...

    // Q: Why is there a __nop() before __debugbreak()?

> you can still use it with smart pointers provided by any other library

Is the point of having a kitchen-sink library like this not that you dont have to reach for a 3rdparty library for things that you need 'all the time'?

Certainly, not everyone needs it.

...but, not everyone needs threads either. Not everyone needs an http server; and yet, if you have an application framework that provides them, when you do need them, it saves you reaching for yet-another-dependency.

Was that no the point from the beginning?

unique_ptr is a fundamental primitive for many, as you see from some other frameworks (1), and implementation is not always either a) trivial, or b) as simple as 'just use std::unique_ptr'.

This does seem like a very opinionated decision with reasonably unclear justification.

It is not publicly available. If you click on this link you get a 404 page: https://github.com/EpicGames/UnrealEngine You actually have to go and subscribe, agree to their terms, and then you get to view the source code. It happens to be free, but it is by no means "public".

https://github.com/EpicGames/UnrealEngine/tree/5.2.0-preview-2 For anyone wondering

Like I said before, you have the fixed code here (commit: 23937975).

Before you can access the repository at https://github.com/EpicGames/UnrealEngine, you must: be an Unreal Engine subscriber. have a GitHub account. have associated your GitHub account with your Unreal Engine account as described on the UE4 on GitHub page.

What you need to do is follow this link and diff my file with Epic's file. You can grab settings that I have from mine and plop them into a custom one for yours. Just be mindful if you're developing in VR for what settings you bring over.

Originally it was going to be NetworkPrediction (need to be signed into a github account with Unreal Engine access for that link to work), but since David Ratti left Epic that died and they stopped working on it. (I didn't know it was dead, that was the CMC replacement I was referring to)
