Twine Version: 2.4.0
I’m attempting to make a game on Twine, but I’ve run into an issue. I’m sure I’m making a basic mistake here, but I can’t quite figure it out. I need to create a gate for the player to continue once they choose their backgrounds. They can only choose two, so I need to create an If and Only if statement for 2 backgrounds. If that’s true, then the continue button will appear.
I realized that first I need to get a value for number of backgrounds, so I wrote the following code. The backgrounds use a checkbox macro:
(checkbox: 2bind $bkthtr,"Theatre")
and according to the test screen, the Boolean functions are working. Checking off the checkbox turns $bkthtr from false to true. So then I wrote the following code to try to determine the number of backgrounds checked off.
(set: $bkcheck to 0) (if:$bkcher is true)[(set: $bkcheck to it + 1)] (if:$bkthtr is true)[(set: $bkcheck to it + 1)] (if:$bksprt is true)[(set: $bkcheck to it + 1)] (if:$bkmath is true)[(set: $bkcheck to it + 1)]
The issue is, $bkcheck shows up in the test as always equalling 0. If I had to guess, I’m misunderstanding some sort of fundamental aspect of how the timing works here. What I want to tell the system is “when this box is clicked, add 1 and only 1 to $bkcheck,” but I think something in the timing is off here. If anyone could help explain why this code isn’t working that would be greatly appreciated.
Here’s what I mean by the “test screen.” Shows two boxes clicked, notice the true Boolean variable.
Please let me know what I’m doing wrong and if you need any other information.
