Also move all object sounds to global Sound.ocg so they are still played.
This is to prevent naming collisions. All sounds are moved because otherwise all scripts would have to be adjusted. Also, the distinction between sounds in definitions and sounds in Sound.ocg was rather arbitrary.
It will also ensure most sounds are reloaded when sound is turned off temporarily, although that should better be fixed properly.
The main difference is now that the check for walls is only done closer to the fish and, to compensate lacking foresight, walls trigger stronger intention to turn.
Additionally, wall vision works slightly differently now, because it's not one vision set (angle) but two distance sets (left: close/far, right: close/far). This
should enable a wall being both left and right (e.g. when swimming in a tunnel) and hopefully lead to a bit straighter trajectory in such cases.
Also, fishes now don't swim 100% straight when they have no sensory input. That looked rather strange in a huge ocean.
PPS: also reduced slimness of fish. Very slim fish looked stupid.
libpng >1.6 keeps nagging because of that.
Quick bash script to do so:
find . -name *.png \
| while read f; do
n=$(pngcrush -ow -rem allb-reduce "$f" 2>&1 | grep -c 'incorrect sRGB');
if [[ $n -gt 0 ]]; then
git add "$f"
else
git checkout "$f"
fi
done
