Custom deleters of ScopedPtr are not currently fully conforming to
C++11's support for custom deleters in std::unique_ptr for the
sake of simplicity of implementation. Unlike in the standard
library, plain functions and lvalue references are not supported,
nor may custom deleters be passed to the constructor at runtime.
This can be improved in the future, if necessary, by doing what
standard library implementations usually do and creating a Pair
class that uses the Empty Base Optimization idiom to avoid extra
storage overhead of the deleter instance when it is not needed, as
in typical standard library implementations, plus some additional
type traits to support the necessary metaprogramming for the
different type overloads.
Getting the address of an rvalue is invalid, and not necessary
here.
Once C++11 can be used always, this utility function can just be
replaced with std::to_string.
SDL does not like this and will raise an assertion when built with
internal SDL assertions turned on. With internal assertions turned
off, it will still call SDL_SetError any time a null pointer is
passed, though it will not raise an assertion or crash.
This reverts commit bf69b25e33.
The original game had slight differences between the code for each
chapter. Part of these changes was to simplify the code and unify
some of these differences, particularly in the checks for clickable
areas, where the code is using Common::Rects with contains() now.
I have play tested the whole game with these changes, there are no
visible regressions, and the game is still completable. Thus, I'm
restoring the changes to the engine.
This reverts
1f1d8607 DRASCULA: Merge the floor coordinates into _walkRect
1e1b6f7c DRASCULA: Rename gotoObject() to walkToPoint() and simplify it
2bf05c2a DRASCULA: Clean up room variables, and simplify some related checks
Reverting due to unanswered questions about why the changes in behaviour
in 2bf05c2a74 are correct.
