Help with SensitiveIf() command?

[Samitha]

Hello !

I was browsing the forums for some help on making a button have multiple actions and found this: viewtopic.php?t=37185
So I decided to apply the same logic to my own button but it didn't work.

I'm trying to get my button to be sensitive to a specific condition: having a gallery image unlocked. So I found the SensitiveIf() command, but I end up getting an error. The code I used for my button is:

Code: Select all

imagebutton auto "gui/gallery/replay_%s.png" action SensitiveIf[SetVariable("persistent.unlock_cg1", True), Replay("start")]

And the error I got is this:

Code: Select all

I'm sorry, but an uncaught exception occurred.

After initialization, but before game start.

Thanks in advance!

Hello !

I'm trying to get my button to be sensitive to a specific condition: having a gallery image unlocked. So I found the SensitiveIf() command, but I end up getting an error. The code I used for my button is:

imagebutton auto "gui/gallery/replay_%s.png" action SensitiveIf[SetVariable("persistent.unlock_cg1", True), Replay("start")]

The parentheses for action is placed wrong. It should be this way

Code: Select all

imagebutton auto "gui/gallery/replay_%s.png" action [SensitiveIf(SetVariable("persistent.unlock_cg1", True)), Replay("start")]

(I think)

[shin.e.d]

I think SensitiveIf only works with persistent when it's written like this: (otherwise it does nothing.)

Code: Select all

imagebutton auto "gui/gallery/replay_%s.png" action [SensitiveIf(persistent.unlock_cg1==True), Replay("start")]

Also you did have a bracket [ in the wrong place.
Ren'py's code is simliar to python. Square brackets [ ] are used to begin and end a python list. Which has multiple items.
Python list example... backpack = ["book","lunchbox","cat"]
In Ren'py, screen actions can be put in a list to do more than just 1 action.
Ren'py reads it from left -> right. So order matters.

If you'd like your replay button to do a Dissolve() transition to the scene it would look like this:

Code: Select all

imagebutton auto "gui/gallery/replay_%s.png" action [With(Dissolve(1.0)), SensitiveIf(persistent.unlock_cg1==True), Replay("start")]

The With(dissolve) is 1st. But if With(dissolve) was last it won't dissolve. Because if Ren'py does the Replay() action 1st, it won't see With(dissolve) after, as it's stuck replaying.

Though screens apparently don't need brackets [ ] as I saw in the forum post you linked...
only commas. I actually didn't know that... But people seem to still like using brackets anyway.

Thank you both for your replies!

The one method that worked was shin.e.d's:

I think SensitiveIf only works with persistent when it's written like this: (otherwise it does nothing.)

Code: Select all

imagebutton auto "gui/gallery/replay_%s.png" action [SensitiveIf(persistent.unlock_cg1==True), Replay("start")]

And I added the dissolve too 'cause I think it looks better

Also, thanks for the brief explanation on brackets, I am still a newbie and didn't quite know actions could be thought of as dictionaries. I really can't thank you enough And I'm glad we both learned something out of this (?)!
