Zaloa

Zaloa takes input terrain tiles, and merges them together.

It is designed to be run as middleware to dynamically generate alternate tile sizes from 256px sources.

Sizes and tilesets

Zaloa uses two tilesets as its source:

1. terrarium
2. normal

Supports 512, and buffered variants of 256, namely 260 and 516. The variants have a 2 pixel buffer on each edge.

Tile Generation

The larger tiles are generated by sourcing the relevant neighbors from the 256px sources.

In the diagrams below, o is the source tile, and the xs represent the neighbors used.

Edge Cases

When on the “edge”, there isn't a neighboring tile to source. Zaloa's behavior is:

• column edge: wrap around and use the tile from the other “side”.

eg: The left neighbor of 2/0/2 will be 2/3/2

• row edge: the source tile is “copied” into the necessary location.

eg: The top neighbor of 2/2/0 is 2/2/0 itself, ie the top 2 rows of pixels are re-used as the buffer.
