Profiling indicated that a little time (< 10% of `ApplyBlockActions`'s
total execution time) is spent on `Deque` when a large chunk of block
is being removed. Thus even *if* this commit slows down things, the
performance impact would be insignificant.
- Replaced raw pointers with references or smart pointers. Nullable
references are represented by `stmp::optional<const T&>`. (There are
many raw pointers still remaining. They should be replaced at some
point.)
- Added class template specializations `stmp::optional<T &>` and
`stmp::optional<const T&>`.
- Fixed `stmp::optional`'s various behaviors
- `World::{players, playerPersistents}` are now `std::array`.
- More uses of `stmp::optional` to clarify the semantics
- Renamed `PlayerThrownGrenade` to `PlayerThrewGrenade`
- Replaced old-style `for` loops with range based ones
- Deleted `Player`'s default constructors and `operator =`
- Deleted `TCGameMode`'s default constructor and `operator =`
- Deleted `CTFGameMode`'s default constructor and `operator =`
- Replaced `static_cast` with `dynamic_cast` for down-casting
- `RefCountedObject::operator*()` no longer requires non-constness to
return `T &`.
- Replaced the uses of `std::vector::operator[]` with `std::vector::at`
for bounds checking.
- Made some methods of `GameMap` `const`.
- Added some null checks.
`IRenderer::{FrameDone, Flip}` are now called in `RunFrameLate` instead.
This makes it possible to create a `View` wrapping another `View` to
insert a new 2D drawing pass, which is necessary to render the system
console.
This commit adds new model rendering options
`ModelRenderParam::{ghost, opacity}`.
> Specifies that the model is not an actual object in the virtual world,
> thus does not affect the shading of other objects and does not appear
> in a mirror.
> ...
> In exchange, it allows the use of an opacity value other than `1`.
