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.
The optimizer is going to remove dead code anyway, and has the
additional advantage of doing syntax checking, so the code won't
silently break when someone changes something.
Scenario parameters are useful in a script-only context (such as the one
mape uses). C4AchievementGraphics introduces a dependency on C4Surface
which isn't available in that context.
Previously, it would just use first pixel of the texture image. With our
current textures, this is a pretty bad approximation. For example,
firestone ends up yellow rather than red.
Additionally, this helps tools like mape/ocmapgen which do not load any
texture graphics but just set the texture's average color.
This also fixes the sky color which was previously overwritten.
Previously, the SReq packet would only be sent after receiving an
ID from the netpuncher. Instead, we can send the request as soon as the
C4NetIOUDP connection setup finishes.
With the IPv6 support, hosts now often list around 20 addresses.
However, most of these are local only and thus rarely result in a
successful connection. With the introduction of address sorting in
7d5596220 ("Sort addresses used for initial host connection",
2017-02-26), the connection succeeds with the first few addresses most
of the time.
This commit changes the initial connection process to start with only
the first four addresses. After 100 ms, it proceeds with the next four
addresses and so on. This should reduce the packet volume significantly
as the connection should be established after only one or two steps.
We may want to tweak the parameters if this turns out to make joining
slower in practise. In a "normal" setup, the first four addresses should
be the IPv6 privacy and stable addresses, and the next four addresses
should include the IPv4 addresses from masterserver and netpuncher.
100 ms are long enough to get an answer from the host and short enough
to not bother the player too much.
Instead of "Compiler" and "Decompiler", which make me look up what's
even going on each time I see them, use the standard terms "serializer"
and "deserializer".
C4Language is the only consumer of GetRelativePath. It cannot handle
arbitrarily sized paths, so discourage new code from using it by moving
it to C4Language.cpp.
Also remove the buffer size parameter which was always defaulted anyway
and use template parameter deduction to always get the correct size.
