This function converts a single value (preferably a Lua table) into a JSON encoded string. You can use this to store the data and then load it again using fromJSON.
Syntax
string toJSON ( var value [, bool compact = false ][, string prettyType = "none" ] )
Required Arguments
- var: An argument of any type. Arguments that are elements will be stored as element IDs that are liable to change between sessions. As such, do not save elements across sessions as you will get unpredictable results.
Optional Arguments
NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.
- compact: a boolean representing whether the string will contain whitespaces. To remove whitespaces from JSON string, use true. String will contain whitespaces per default.
- prettyType: a type string from below:
- none
- spaces
- tabs
Returns
Returns a JSON formatted string.
Example
This example shows how you can encode an array. The string json should equal "[ { "1": "dogs", "mouse": "food", "cat": "hungry", "birds": 4 } ]" after executed.
local json = toJSON ( { "dogs", cat = "hungry", mouse = "food", birds = 4 } )
Requirements
| Minimum server version | 1.0 |
|---|---|
| Minimum client version | 1.1.1-9.03316 |
Note: Using this feature requires the resource to have the above minimum version declared in the meta.xml <min_mta_version> section. e.g. <min_mta_version server="1.0" client="1.1.1-9.03316" />
