end

.convert_tileset(filename, max_size = 4096, min_size = 1024)

Convert a tileset to a PSDK readable PSDK tileset (if required)

Examples:

Converter.convert_tileset(“Graphics/tilesets/tileset.png”)

Parameters:

  • filename (String)
  • max_size (Integer) (defaults to: 4096) —

    Maximum Size of the texture in the Graphic Card

  • min_size (Integer) (defaults to: 1024) —

    Minimum Size of the texture for weak Graphic Card
