Explorer damage (see earlier messages for background). Previously,
explorers' ground attacks would hit every square of an attacked
building. This means that a 3x3 building would be hit 9 times in a
single attack, and the explorer hitting it would get 9 times the
experience points. This means that explorers increase in levels
extremely quickly, and can easily do over 100 points of damage to a
building in a single attack. I've now added a little code to make sure
that each explorer attack hits each building only once. I've done this
by storing previously-hit buildings in a std::set, because we need to
store a small (but variable) number of building IDs in a way optimised
for quick searching.
The inn bug (see earlier messages for background). Previously, globs
would subscribe to an inn if it had any free slots, then some time later
be accepted or rejected. If the inn was nearly full of wheat, but could
still take more fruit, any number of globs could subscribe to the inn,
then be rejected when it turned out they weren't near fruit. At which
point, they'd idle for a moment before re-applying. As a quick fix,
I've set the globs only to apply to the inn if they have a chance of
being accepted. Although they can still spend some time being
unnecessarily idle, the bug is essentially fixed. To offset any
potential slowdown this causes in the game, I've optimised a related bit
of code in the function that accepts/rejects globs - the function now
does exactly the same thing, just a bit quicker.
