Helper class to handle INI-style files.
|
||||
</brief_description>
|
||||
<description>
|
||||
This helper class can be used to store [Variant] values on the filesystem using an INI-style formatting. The stored values as referenced by a section and a key. The stored data can be saved to or parsed from a file, though ConfigFile objects can also be used directly with accessing the filesystem.
|
||||
The following example shows how to parse a INI-style file from the system, read its contents and store new values in it:
|
||||
[codeblock]
|
||||
var config = ConfigFile.new()
|
||||
var err = config.load("user://settings.cfg")
|
||||
if err == OK: # if not, something went wrong with the file loading
|
||||
# Look for the display/width pair, and default to 1024 if missing
|
||||
var screen_width = get_value("display", "width", 1024)
|
||||
# Store a variable if and only it hasn't been defined yet
|
||||
if not config.has_section_key("audio", "mute"):
|
||||
config.set_value("audio", "mute", false)
|
||||
# Save the changes by overwriting the previous file
|
||||
config.save("user://settings.cfg")
|
||||
[/codeblock]
