Hello everyone, I'm new here. I want to learn everything that I need to know about Text-based games. I have a idea in mind, but I don't know where to start.

Try the tutorial to get an idea of how the software works.

Otherwise you'll need to be a bit more specific as to what you need help with. It's not really possible to explain everything you might need to know without knowing what you want to do.

Here's a start...
Call it the dictionary of almost everything...

Other than that... download a few games and play them to get a feel for how they play....
then look at the code to see how it's done...

After the tutorial (the basics of using quest software/engine), the 'bread and butter' of game making (coding) is learning Attributes and the 'if' Script usage (basic scripting) comes first:

or

then you can look into using/learning the List/Dictionary Attributes.
