The library that implements Conway's Game of Life.
Disclaimer: this library was written directly on an Android smartphone with the QLua IDE.
- models:
- size:
- supporting of checking if a point is inside;
- supporting of checking if an other size with offset fits inside;
- supporting of textual representation;
- point:
- supporting of translation;
- supporting of scaling;
- supporting of textual representation;
- field:
- storing only of set cells:
- ignore outside points;
- supporting of counting of set cells;
- supporting of checking if a cell is set:
- ignore outside points;
- supporting of checking if an other field fits inside;
- supporting of mapping;
- supporting of textual representation;
- storing only of set cells:
- placed field:
- extends the field model;
- storing a field offset;
- working with cells taking into account the field offset;
- supporting of checking if an other field with offset fits inside;
- supporting of copying the existing field with setting an offset;
- supporting of textual representation;
- size:
- generating of a random field:
- customizable filling factor;
- limiting by a cell count:
- lower limit;
- upper limit;
- operations with fields as with sets:
- union of fields:
- supporting an offset for the second operand;
- restricting of the result size by the size of the first operand;
- complement of fields:
- supporting an offset for the second operand;
- intersection of fields:
- supporting an offset for the second operand;
- union of fields:
- operations with fields as with matrices:
- rotating of a field clockwise;
- populating of a field according to Conway's Game of Life rules:
- using of the naive algorithm with iterating and copying of a whole field.
