Function ProjectSettingsSingleton.loadResourcePack

Loads the contents of the .pck or .zip file specified by pack into the resource filesystem (res://). Returns true on success. Note: If a file from pack shares the same path as a file already in the resource filesystem, any attempts to load that file will use the file from pack unless replace_files is set to false.

  const(String) pack,
