I'm completely stuck in the tutorial. I want to be able to do the switch command in the custom commands part, where you can have your character talk to different people and get different outcomes for it, but I cannot seem to get the code to work. My game says there's an error running the script. Error compiling the expression and unknown variable. I did it exactly in the tutorial, but I've only started trying to code this game yesterday. Am I missing something?

So I mucked around with it more, and figured out its two scripts in one script. I finally got it to work but I had a bit of trouble where it was still exactly the same but wasn't working well. Either way what a ride.

Hello, NinjaNin.

Sorry none of us saw this in time to help, but I'm glad you got it going! (And in less than an hour! Kudos!)

If you need any more help, post it up.

Best wishes!

here is my completed tutorial game code, which you can use to compare with your own, if you're stuck on anything:

(this is old, and the tutorial might have changed a bit since when I did it, so everything may not be exactly the same. Also, I have some extra stuff in it that I was trying out)
