Helper class for creating and parsing JSON data. The [JSON] enables all data types to be converted to and from a JSON string. This useful for serializing data to save to a file or send over the network. [method stringify] is used to convert any data type into a JSON string. [method parse] is used to convert any existing JSON data into a [Variant] that can be used within Godot. If successfully parsed, use [method get_data] to retrieve the [Variant], and use [code]typeof[/code] to check if the Variant's type is what you expect. JSON Objects are converted into a [Dictionary], but JSON data can be used to store [Array]s, numbers, [String]s and even just a boolean. [b]Example[/b] [codeblock] var data_to_send = ["a", "b", "c"] var json = JSON.new() var json_string = json.stringify(data_to_send) # Save data # ... # Retrieve data var error = json.parse(json_string) if error == OK: var data_received = json.get_data() if typeof(data_received) == TYPE_ARRAY: print(data_received) # Prints array else: print("Unexpected data") else: print("JSON Parse Error: ", json.get_error_message(), " in ", json_string, " at line ", json.get_error_line()) [/codeblock] Returns the [Variant] containing the data of a successful [method parse]. [b]Note:[/b] It will return [code]Null[/code] if the last call to parse was unsuccessful or [method parse] has not yet been called. Returns [code]0[/code] if the last call to [method parse] was successful, or the line number where the parse failed. Returns an empty string if the last call to [method parse] was successful, or the error message if it failed. Attempts to parse the [param json_string] provided. Returns an [enum Error]. If the parse was successful, it returns [code]OK[/code] and the result can be retrieved using [method get_data]. If unsuccessful, use [method get_error_line] and [method get_error_message] for identifying the source of the failure. Converts a [Variant] var to JSON text and returns the result. Useful for serializing data to store or send over the network. [b]Note:[/b] The JSON specification does not define integer or float types, but only a [i]number[/i] type. Therefore, converting a Variant to JSON text will convert all numerical values to [float] types. [b]Note:[/b] If [param full_precision] is [code]true[/code], when stringifying floats, the unreliable digits are stringified in addition to the reliable digits to guarantee exact decoding. The [param indent] parameter controls if and how something is indented, the string used for this parameter will be used where there should be an indent in the output, even spaces like [code]" "[/code] will work. [code]\t[/code] and [code]\n[/code] can also be used for a tab indent, or to make a newline for each indent respectively. [b]Example output:[/b] [codeblock] ## JSON.stringify(my_dictionary) {"name":"my_dictionary","version":"1.0.0","entities":[{"name":"entity_0","value":"value_0"},{"name":"entity_1","value":"value_1"}]} ## JSON.stringify(my_dictionary, "\t") { "name": "my_dictionary", "version": "1.0.0", "entities": [ { "name": "entity_0", "value": "value_0" }, { "name": "entity_1", "value": "value_1" } ] } ## JSON.stringify(my_dictionary, "...") { ..."name": "my_dictionary", ..."version": "1.0.0", ..."entities": [ ......{ ........."name": "entity_0", ........."value": "value_0" ......}, ......{ ........."name": "entity_1", ........."value": "value_1" ......} ...] } [/codeblock]
