[Solved] Fill variable with value of another variable

[QueenBee]

Hi, I would like to ask how to fill a newly created variable with current value of existing one.
What I am trying to achieve: I want to record an exact day (in-game one) when a player returned a book and fill a new variable with that value. I am counting them as simple numbers. No week system involved. So the next event will be available in a few days automatically.

I tried to write it in code, googled it but didn´t figure out what to do. Thanks to anyone who can help me.

Assuming current_day is a simple number:

Code: Select all

$ book_returned = current_day

[Remix]

day_book_returned = current_day

You might want to default it as zero though, then just adjust it to match current day when the book return event occurs.

I hesitate to throw this in and muddy the waters since it sounds like you're very new to programming, but we ought to at least mention that there is kind of a trap lying just next door to the question you asked. It's a Python trap, nothing specifically to do with Ren'py.

The key is, Ocelot's comment about "assuming it's a simple number" is *extremely important*. If your variables are all just numbers, booleans (True/False) or strings, that's all you need to know. But if you are trying to save a copy of a *list*, *dictionary*, or *object* (instance of a Class), you need to learn the difference between "copy by value" and "copy by reference".

Thank you all for help and kind responses. I solved it. I think that I was trying to use $ also after = assuming that othervise it will just be set to text "day'.

I will definitely read "copy by value" and "copy by reference", didn't know that there is some difference.
