Hello Sun1010,
The State parameter is a structure that contains data that is used when creating the touch interface. You can define the starting state of this interface such as if it is hidden or not, if the inputs are activated… You don’t need to create a variable, you can either brake the parameter or use the “make” node.
Yes the documentation is outdated! I have just finished the development of version 3.0 and I will update the website as well as the documentation.
