Return time in seconds since timer was last reset

Creates an entity and returns and Enttiy handle to the caller. @param(name): Optional and used for debugging purposes

Return T* if data exists in dense list, or nullptr if not.

Executes a passed lambda on all the entities that match the passed parameter pack. Provided function should follow one of two forms: [](Component& c1

Removes data from the dense list, and sets the sparse index to a tombstone (null) value

Check if the EntityIndex currently has associated data in the dense list

This returns a copy of all EntityIndex that currently have data in the dense list so we can safely delete from the vector while iterating.

Deletes an active entity and its associated components. Overwrites the given entity to NULL_ENTITY_ID.

Useful when you want a way to iterate a view via indices. Usage: auto packed = ecs.view<A, B>().packed(); for (size_t i = 0; i < packed.size(); i++)

Returns true iff all the pools in the view contain the given EntityIndex

Returns the dense index for a given EntityIndex, or a tombstone (null) value if non-existent

Queries whether the entity is currently 'alive' and can be operated on by the ECS. It does this by comparing the version encoded in the Entity ID wit

Returns the next unused component index. Don't call directly for component type lookup, since each call generates a new index. It is intended to be u

Wraps the EntityVersion back to 0 once it exceeds MAX_VERSION_VALUE

Returns true iff the EntityIndex does not exist in at least one excluded pool

Inserts an index into the sparse list that maps to the dense list, associating m_dense[m_sparse[entity_index]] == m_dense[dense_index]
