MatrixMap<T> class

A data structure that organizes items of T in a 2d map with int keys.

This structure prioritize rows over columns.

Implemented types

• MatrixMapReadOnly<T>

inherited

operator [](IntVector2 coordinate) → T?

Get element at a position corresponding to coordinate.

override

operator []=(IntVector2 coordinate, T item) → void
