For pixel art the [default import settings](https://blog.luevano.xyz/g/flappybird_godot_devlog_1.html#default-import-settings) no longer affect much, but it's worth to double check as they changed from `Texture` importer to a `Texture2D` and the imported textures could be messed up. The important parameter to change is the *Filter* for the textures in the *Inspector* of each node but since all nodes inherit parameters by default, changing on the parent nodes (or just once in the root such as `Main.tscn`) will suffice: Change *Inspector -> CanvasItem -> Texture -> Filter* from "inherit" to "Nearest". +== TODO == update this to this setting https://ask.godotengine.org/122518/how-to-import-pixel-art-in-godot-4 + # Player Now that the game at least runs, next thing is to make it "playable".

For the scripting part, I basically merged all 3 scripts (`world_tiles.gd`, `pipe_tile_map.gd`, `ground_tile_map.gd`) into one (`world_tile_map.gd`) and immediatly was able to delete a lot of signal calls between those 3 scripts and redundant code. + +The biggest change in the scripting side are the functions to place tiles. For *Godot 3*: + +```gdscript +# place single tile in specific cell +void set_cell(x: int, y: int, tile: int, flip_x: bool = false, flip_y: bool = false, transpose: bool = false, autotile_coord: Vector2 = Vector2( 0, 0 )) +void set_cellv(position: Vector2, tile: int, flip_x: bool = false, flip_y: bool = false, transpose: bool = false, autotile_coord: Vector2 = Vector2( 0, 0 )) +``` + +Whereas in *Godot 4*: + +```gdscript +# place single tile in specific cell +void set_cell(layer: int, coords: Vector2i, source_id: int = -1, atlas_coords: Vector2i = Vector2i(-1, -1), alternative_tile: int = 0) +# erase tile at specific cell +void erase_cell(layer: int, coords: Vector2i) +# place pattern +void set_pattern(layer: int, position: Vector2i, pattern: TileMapPattern) +``` + +So the main differences: `layer` needs to be specified, `source_id` which specifies which atlas to use (ground or pipe in our case), and instead of providing an index for a tile an `atlas_coords` is required. `alternative_tile` is used in case of tiles that have alternatives such as mirrored or rotated tile, not required in my case. Setting `source_id=-1`, `atlas_coords=Vector21(-1,-1)` or `alternative_tile=-1` will delete the tile from the `coords`. + +As for the pattern, a pattern can be obtained from calling the `get_pattern` method on the `tile_set` property of the `TileMap`.
