Thinking of making a renpy gme but basically not idea to use renpy any tips?

While i found other VN tools that make it easier some of the ideas is until you make this actions nº of times you dont unlock a special dialogue so if any of you guys could help

Just define a variable that goes up each time you do the “action”. And then add an if clause that checks the variable to display the special dialogue once it has reached your desired value)

the thing is idk how to do the rest

There isnt any tool or other sistem that works something like this
