Hello, guys! I stumbled upon a question that I can not answer so it would be greatly appreciated if someone takes from their time to help a teacher in need.
The idea of the code is to “collect” a key so the player can open a door only after the player has found and clicked on the key I a chest.
If we add the number one to the list Backpack, I guess that the item scepter that we added to it earlier gets replaced by it.
“change X by Y” block is the same as adding Y to the X, i.e. X = X + Y.
So in your case change Backpack by (Backpack + 1)
is the same as Backpack = Backpack + (Backpack + 1)
That is why when you have Backpack == 1 you get Backpack == 3 after this block.
If you want to just add 1 to the variable then you can simply use block change Backpack by 1. Or you could use the block set variable Backpack to (Backpack + 1)
Thank you @Dmitry! Your answer helped me. Could you also tell me - why when we add the number one to the scepter ([ModelItem[name = “Scepter”;…) it changes to the number one and not just the name of the scepter + 1, i. e. concatenation ([ModelItem[name = “Scepter”;…1)?
