The "normal" connection process is a three-way handshake (Conn->,
<-Conn, ConnOK->). When establishing a multicast connection, this
handshake is repeated via the MC address. However, the code always
expected that second handshake to happen and thus ran into a timeout on
the client in the non-MC case, repeating the handshake a second time. In
the end, it usually still worked as the server supports reconnecting,
but packets may be lost in the process.
Before commit 5a652f23e ("Fix missing C4PXSSystem::Clear
implementation"), ChristmasIce would keep all snow PXS between scenario
section changes. That looked pretty neat, so I'm introducing this script
function to allow properly implementing it.
The old system allocated chunks of PXS on demand. I can't think of a
good reason to do this.
The savegame format changes slightly to not require saving full chunks,
however old savegames will still load fine (invalid PXS within chunks
are moved out during the next Execute() call).
Savegames with a foreground material diff but no background material
diff would not apply the foreground diff at all. As the background
material rarely changes, this broke runtime joining for most scenarios.
Objects will be incinerated by incendiary material (which before was only possible by using ContactIncinerate).
local MaterialIncinerate = true; - object will burn in lava not from other burning objects.
Imagine lhs being 0 and rhs being more than int32_t can handle. And then imagine subtracting them and casting them to int32_t.
That's what happened e.g. in void C4ShaderCall::Start() when ScriptShader.LastUpdate was 0. This caused the shaders to reload every frame;
at least when in the main menu. This lead to serious lagging (of the cursor) for me.
Note that the subtraction operator in C4TimeMilliseconds.cpp has a similar issue. This might need a fix or at least high awareness by users. Maybe an assert or something.
PS: Who thought that doing the comparison with a subtraction was a good idea? This is not assembler :I
Having the ctor defaulted confuses MSVC 2015 and makes it not use the
templated ctor below even for calls with a parameter list,
thus skipping required initialization.
This fixes a slowdown in scenario selection when some of the dependency folders (e.g. qt) are searched for scenarios.
Should also fix a bug where music is loaded from the exe path instead of planet/ if present
A follow-up on a previous PR GH-41. The discussion in the forum can be
viewed at http://forum.openclonk.org/topic_show.pl?pid=33086.
Run clang-tidy (without auto, pass-by-value and using checks) to fix the
header files not modified in the previous PR.
Summary of the changes:
- C++11 member initialization.
- nullptr instead of 0 for pointers.
- override for functions declared virtual in base class.
- default trivial special member functions
Consolidate the include statements scattered across the code in accordance
with the comment in C4Include.h. The advantages are listed in the same
comment.
Furthermore, it follows llvm-include-order which is the logical
extrapolation of the project's style guideline wherever possible
(C4Include.h being the most-frequent exception).
Alut's pkg-config definition only adds the top-level include directory
containing the AL directory to the include paths. This works on most
platforms because OpenAL adds that AL directory. However, with nix,
these two directories are distinct and the build fails.
