* In the list of variables (of the scene, of an object or global variables), you can now specify the type of the variable: number, text, boolean, array or structure. * Boolean variables can be "true" or "false. They can have their values checked with conditions, and updated with actions. They are a good way to store information about if something is enabled or not (is an item equipped, is something selected, etc...). * Array variables can contain multiple values, indexed by a number. New values, including any kind of variables, can be appended to an array during the game. Arrays can also have a value removed, and using the event "For each child variable", you can run conditions and actions for each value that is present in the array. * Boolean and arrays are also supported when you transform a variable from or to the JSON format - which is ideal to send web requests, read configuration files or store any kind of arbitrary data. * Finally, note that array values can themselves be arrays, structures or any variable. This can be useful to construct advanced logic. You can also access arrays (as well as any variable) from JavaScript code block events.
