Lists, whitespace and seperate lines. (Harlowe)

Caeora

Hey guys,

I’m working on an inventory system and while I can get a bunch of stuff to work going backwards and forwards I've run into a problem that is driving me mad. The inventory displays itself on a separate page, when an item or weapon is set to true it simply displays that item in the “inventory” (another page). However! The list of items in the inventory takes up a huge bunch of space. Using {} on either end of this long list does fix this problem but I want each item on the list to take up a separate line rather than all being clumped together. In other words, instead of looking like this:

Wood Axe - Mace - Short Sword - Chain Mail - Buckler - Torch - Bedroll

I’m trying to make the list of items look like this:

Wood Axe -
Mace -
Short Sword
Chain Mail -
Buckler -
Torch -
Bedroll -

This problem is further complicated by the fact that I’m only setting certain items to be true at certain times, this means that without using {} huge gaps of white space appear from the items that have not been set to true but are still present on the page. I've tried using {} in different ways inside the code with varying results but nothing that works for the entire list. Does anyone have an idea?

1st Page 
(set: $Bedroll to true)
(set: $Torch to true)
(set: $Buckler to true)
(set: $LightHelm to true)
(set: $ChainMail to true)
(set: $Mace to true)
(set: $WoodAxe to true)
(set: $ShortSword to true)

The trick is to use a back-slash on the end of each line to suppress the line-break and to add the line-break inside the (if:) macro's associated hook.

note: My example will only do the first seven items, just use the same technique for all of the rest.

1. Initialise your variables in your story's startup tagged passage:

(set: $Club to false)
(set: $Dagger to true)
(set: $WoodAxe to true)
(set: $Javelin to false)
(set: $Hammer to false)
(set: $Mace to true)
(set: $Staff to true)

2. Use CSS like the following to suppress the startup adding empty space to the first passage of your story, it goes in your Story Stylesheet area:

tw-story tw-include[type="startup"] {
	display: none;
}

3. Format your (if:) macros and their associated hooks like the following, notice that you don't need the "is true" part if your variable contains a Boolean value.

(if: $Club)[
Club - ]\
(if: $Dagger)[
Dagger - ]\
(if: $WoodAxe)[
Wood Axe - ]\
(if: $Javelin)[
Javelin - ]\
(if: $Hammer)[
Hammer - ]\
(if: $Mace)[
Mace - ]\
(if: $Staff)[
Staff - ]
