Ds1 refactor (#11)
* Refactoring d2ds1 * Adding setters/getters so that state management can be maintained internally when the ds1 struct is altered * Adding unit tests for DS1 * unit tests for ds1 (#4) * ds1 refactor: added test fore some methods; put tests in right order * ds1 refactor: unit tests for all methods * ds1 refactor: fixed build errors * ds1 refactor: lintfix * ds1 refactor: fixed bug with SetWidth, SetHeight methods * ds1 refactor: rename tile_record.go -> tile.go * ds1 refactor: unit test for SetTiles Co-authored-by: M. Sz <mszeptuch@protonmail.com> * renamed some files in d2ds1 * d2ds1.FloorShadow is now private * renamed another file * DS1.Tile() now calls update if dirty * Ds1 refactor: some test improvement (#5) * ds1 refactor: floor_shadow.go: methods Encode, Decode an Hidden are methods of floorShadow * ds1 refactor: test checks, if our methods sets all fields correctly * ds1 refactor: minor bugfixes * i don't remember what's this, but i commit it ;-) * ds1 refactor: reverted some pushed by mistake things Co-authored-by: M. Sz <mszeptuch@protonmail.com> * Ds1 refactor: test bugs + descriptive errors + SetNumberOfWall/FloorLayers (#6) * ds1 refactor: - removed DS1.layerStreamTypes field - written unit test for setupStreamLayerTypes method - added more descriptive error messages for LoadDS1 (and submethods) * ds1 refactor: added some missing error messages * ds1 refactor: fixed test bugs * ds1 refactor: removed unnecessary c1. and c2. comments in ds1_test errors * ds1 refactor: removed fmt from ds1_test * ds1 refactor: fixed bug with SetTiles test + lintfix * ds1 refactor: SetNumberOfWalls * ds1 refactor: SetTile(s) now changes walls/floors length if neccesary * ds1 refactor: removed unnecessary debugging fmt * ds1 refactor: added substitution layer and object with paths to example data Co-authored-by: M. Sz <mszeptuch@protonmail.com> * Ds1 refactor: removed npcIndexes field+fixed SetNumberOfWalls bug (#7) * ds1 refactor: removed npcIndexes field it was unnecessary, because described a number of objects with paths to use in encoder, but we can calculate manually * ds1 refactor: fixed set number of (layers) bug * ds1 refactor: SetNumberOf...Layers now returns error if incorrect number given * ds1 refactor: lintfix * ds1 refactor: rename: setupStreamLayerTypes -> GetStreamLayerTypes Co-authored-by: M. Sz <mszeptuch@protonmail.com> * WIP * Ds1 refactor - tests (#10) * ds1 refactor test: example data * added loader check * ds1 refactor: fixed bug, with loading substitutions; added descriptive error message in engine.go:118 and changed Logger.Error with Logger.Fatal * ds1 refactor: fixed loading bug * ds1 refactor: fixed bug when walls wasn't rendered (now we can see only walls :-) Co-authored-by: M. Sz <mszeptuch@protonmail.com> * ds1: floor rendering bugfix * ds1: implemented encode layers method * ds1: implemented encoder * ds1: update of ds1_test Co-authored-by: gravestench <dknuth0101@gmail.com> Co-authored-by: M.
