Several questions: Hooks, History, and Setter Links

Sinthioth

Hi, I'm brand new to twine and running into some difficulties.

First, I am getting a "missing ] after element list error" for the following hook:

leaving me behind in a pool of my own(if: $bloodied lte 1) [[[blood. | Art Gallery]]]

I did put an extra bracket at the start and end but it doesn't register I guess?

Second, I have a "Missing ) after argument list" for the following:

(if: $light is 0 and not $history: contains "Art Gallery")

I'm guessing I need some parentheses for adding the not history condition but I've tried multiple combinations and all of them return syntax errors. Is there something about using "and" statements I don't understand?

I also couldn't find any documentation about using "setter links" to alter variables in this version.

Any help would be greatly appreciated!

If you haven't seen it yet, the Harlowe documentation.

You have two issues here:
[list type=decimal]
There is no lte operator in Harlowe, you want the <= operator.  That's what's causing the "missing ]" error.
You probably do not want to put leading/trailing whitespace in your link markup.  Harlowe treats leading and trailing whitespace in the link markup as significant, meaning your like goes to " Art Gallery" (note the leading whitespace) instead of "Art Gallery" as you probably intended.

You murdered the (history:) macro and it seems that you must wrap the history contains expression in parens or it breaks when used with the not operator.  For example:


(if: $light is 0 and not ((history:) contains "Art Gallery"))[]

Setter links do not exist in Harlowe, though someone may have figured out a workaround.  SugarCube has them.  I'm unsure about Snowman.

Ahhhh I see, thank you very much!

One way to simulate Setter Links in Harlowe is by using a hook, click, set, and goto macro combo like the following:


[Option 1]<link1|
[Option 2]<link2|

(click: ?link1)[(set: $var to "A")(goto: "Next Passage")]
(click: ?link2)[(set: $var to "B")(goto: "Next Passage")]


In the Next Passage passage you can selectively show text based on the value of the variable:


(if: $var is "A")[The text to be shown if Option 1 was selected in previous passage.]
(if: $var is "B")[The text to be shown if Option 2 was selected in previous passage.]

Interesting, I may try that out! Also, after applying it the "not history" code isn't working as MadExiles described; I entered it as follows


(if: $light is 0 and not (($history:) contains "Art Gallery"))

but still get a syntax error. Does something special have to happen to the "history" macro if it's in an and statement maybe? I'm at a loss.

Small syntax error in your code, (history:) is a macro so you don't want/need a $ before the macro name.

Try without the extra $:


(if: $light is 0 and not ((history:) contains "Art Gallery"))

TheMadExile

You've misspelled the macro name (again).  It's (history:) not ($history:).  There is no dollar sign ($) in macro names (that's the $variable sigil).

I must've looked at that line a hundred times I can't believe I didn't notice that -.- Thanks for being patient with me, can you tell this is the first programming-esq thing I've ever done? P:

Another way to simulate a Setter Link, and the one I should of thought of first, is to use a link, set, and goto macro combo:


(link: "Option 1" )[(set: $var to "A")(goto: "Next Passage")]
(link: "Option 2" )[(set: $var to "B")(goto: "Next Passage")]

I have a similar (history:) question.

I created a game that's a personality quiz, and I want to display different sentences based on what passages the reader has visited. This is what I have so far:

(if: ((history:) contains "SlantRight"))You are a people person with a nice balance between your head and your heart.

(if: ((history:) contains "SlopeDown"))You can be pessimistic and worry easily.

The problem is that both sentences appear even if those passages are not visited. Can anyone help me with the syntax?

greyelf

The format of your (if:) macros are wrong, the contents needs to be surrounded with square brackets.

Try the following:


(if: ((history:) contains "SlantRight"))[You are a people person with a nice balance between your head and your heart.]

(if: ((history:) contains "SlopeDown"))[You can be pessimistic and worry easily.]


NOTE: Even though the Harlowe documentation shows many examples of the (if:) macro without the square brackets they are required, as show by the following example from there:


(if: $x is 2)[This text is only displayed if $x is 2.]
