I absolutely adore your tutorials! They're priceless for a rookie ruby coder!

I've encountered an error during Tutorial 7 Part 4 - Cooking Script. When I run the script and talk to the "boy" it's not possible to change the recipe you want to cook and when I then press the first recipe "Line 176: NameErorr occured. undefined local variable or method update_details for #<Scene_Cooking:0x2bdbc98>" pops up. Anyone know what I've done wrong?

Here's my unfinished script prototype:

end

$game_party.forget_recipe(number)
end
end

On a side note though, if you have a lot of spare time, It'd be even better if you could do some short but informative tuts
on the short (but important) parts of the RGSS2. For example a detailed walkthrough of Scene_Menu and Game_Picture would
be well appreciated!

Keep on rockin'!

Ok, so to answer both. Firstly you are not updating the windows. You are calling the 'input methods' for those windows of "update_list' and 'update_details', but your still not actually updating the windows. I believe in the demo I did a 'update_windows' method that does this. You could also just add the lines: @list.update and @details.update and it will resolve that one.

Now, the second error is because the update_list is saying to make the details active, which it does. But then if you search for 'def update_details' it does not exist. That is all the error message is saying as well. There is no variable or method by the name of update_details currently, hence it crashes.

Hope this helps.

I see, thanks for the help! I'm just confused why it worked for you in the tutorial when I wrote everything exactly as you did Anyway, I'll just continue with part 5 & 6 and see if I can get it up and running after that, it seems as copying your part of the "def update_details" won't do me any good.
