Jump statement not working with arguments?

#1 Post by unicodepepper » Fri Jan 20, 2017 9:41 pm

I was going to place this in the bug replication section, but first I wanted to make sure this wasn't a feature instead. Let's look at an example code:

Code: Select all

label example:
    call pick("paper")     #works flawlessly
    jump pick("paper")     #causes an exception

label pick(object="stone"):
    "I picked up the [object]"

In the above code, what I'd expect is to pick a paper, then pick another paper, then go back to the main menu. However, the jump statement says that it expected a newline right over the opening parentheses. If that line is commented, the code runs smoothly. Does anyone have any idea why is that, and any tips or alternatives to solve it? I'm using ren'py, if that helps about something. Thanks in advance!

You have no "paper" to pick... I only see "stone"

Did you put return at the end of paper as you did with "stone"?

All I can think of here, is you're jumping to the label "example", and then instantly jumping to another label.
You should change that so there's some kind of user-interaction between the jumps.

Looking at the documentation, it doesn't seem like jumping with parameters is intended. (Call explicitly mentions parameters, jump does not.) Not sure why though. Might be worth raising with PyTom if you'd like. https://www.renpy.org/doc/html/label.ht ... -statement

If you go to (jump to) another line of the code, you can't tell its scope is local or global. It'll share the same global scope, so arguments become meaningless. In that's case, the following would do the same thing.

Code: Select all

jump label(x=1)

jump label
You shouldn't use a same label for both call and jump. If you jump to a label that has the return statement, it leads to the main menu.
