In previous MV2 it was enough to declare a variable in the body of the script like this let my_variable; and then use it in any function inside (read/write some data). But in MV3 this does not work. Are there any alternatives for storing data and reading it in functions? (a data is not exactly text, rather objects). Thanks in advance to any ideas!
