Use temporary structs instead of tuples.
Enforce max line width of 80 characters.
Fix warning related to ECTest.cpp .
Note that currently this commit appears to be unable to be built by GCC,
but compiles OK with Clang.
When reallocating more data, vector moves the original data to a new
buffer. Deque preserves the location of the original data, preventing
invalidated pointers to existing data when additional allocation is
required.
As an alternative to forMatchingSignatures, which calls the given
function on entities matching the given Components/Tags in the
signature, forMatchingIterable allows filtering entities by an iterable
of indices that corresponds to Components/Tags.
All functions called by EC/Manager now accept an additional parameter
as a void* to support user-provided data (or context) for functions
(useful when the function is not a lambda function and doesn't have any
other data stored with it).
EC/Manager and EC/Bitset can now handle types that are not known
(Components or Tags not in the given Components or Tags when created).
Manager::getEntityData now returns a pointer instead of a reference.
Functions passed to Manager::forMatchingFunction (and other similar fns)
should now accept Component fields as pointer types, not reference
types.
Fixed bug where if an entity is deleted during a multiple
signature/function call but matched a later signature/function, it would
still be called in that later function.
Minor fixes as well.
Entity IDs are now guaranteed to not change for a living entity.
Cleanup is replaced by using a std::unordered_set to store deleted
Entity IDs to be reclaimed on later calls to addEntity().
Fixed bug where if forMatchingSignatures and forMatchingSignaturesPtr
was called with some signatures in the TypeList being duplicates, then
only the first duplicate and function pair would be called, and all
other functions paired with other duplicate signatures would not be
called.
Previously, every called function iterated through all entities for
calling the function on matching entities.
Now, callForMatchingFunctions iterates through all entities once,
stores matching entities for each function, then calls the functions on
the matching entities.
EC::Manager::forMatchingSignatures is different from
EC::Manager::forMatchingSignature in that it takes multiple signatures
and functions and iterates through all entities once. The trade-off is
that a vector of vectors is created to store matching entities.
This function can be called to use multiple threads as well, similar
to the "non-plural" version of this function.
See the doxygen-style documentation in src/EC/Manager.hpp for
forMatchingSignatures (or the generated doxygen html) for how to use.
Usage example is in the last unit test function in src/test/ECTest.hpp .
Unordered map does not preserve order in which items were inserted.
This is a problem because an entity id relocated to a previously deleted
one could be read as deleted when iterating through the unordered map.
Thus, it has been replaced with a queue.
clearSomeMatchingFunctions removed for
keepSomeMatchingFunctions and removeSomeMatchingFunctions to
avoid confusion.
Lines now respect 80 column limit.
An unordered_map stores functions, allowing for functions to be
removed by index, and bulk removals with filtering by index.
Also added reset(), which changes the state of the Manager to be
almost identical to a newly constructed one.
