Import Tiled maps into the game

[Luis-Tavares]

The maps of the game are being built on Tiled. Its files are on kcg\luis\tiled files
We need to import different Tiled maps into the game. On the first version, the player is going to select on the load screen which map he's going to play and it'll load an entire map of Tiled.
Later we maybe incorporate Tiled maps into some procedurally generated areas, but you don't need to worry about that right now.
Tiled is free, so I advise you to also download it, so you can check how the map should look like and how the layers are organized.

Looking through the TMX file format, populating the layers should be a straightforward task. The trickier element will be mapping the .tsx resources to the in-game tiles.

.png spritesheets hold many sprites. .tsx files map sprites to spritesheets. Our custom sprite .yaml files also map sprites to spritesheets. Our custom tile .yaml files map tiles to sprites.

Perhaps we should replace our custom sprite .yaml files with the same .tsx files that we are already using within Tiled. Adopting a single source of truth will reduce the friction in adding/updating assets.

Additionally, Tiled supports custom properties. We may be able to embed tile information within these properties to further consolidate the map information.

[ted537]

According to the Tiled documentation on Tile layers, properties only exist on tiles - they cannot be defined on a specific instance of a tile. This is ideal for our purposes.

Perhaps each tile in a Tiled map could have a "cx" property which contains the name of the CX-game tile to insert.

Of the two libraries listed by Tiled, go-tiled appears to be more mature / fully featured.

Note that go-tiled does not currently support infinite maps.

progress

Further progress. Still buggy but sprites for tiles are now being detected automatically

still need to get walls working
