| + | ====Multiple operations in one <<set>> ==== | ||
| + | |||
| + | When you have multiple <<set>> macro tags next to one another, you can replace them with a shorthand that uses only one <<set>>. Simply take the operations in each instance, and join them together using either commas or semicolons. | ||
| + | For instance, these three macro tags: | ||
| + | <code><<set $pants = "large">> | ||
| + | <<set $shoes = "huge">> | ||
| + | <<set $spats = "classy">></code> | ||
| + | ...can be changed to just this: | ||
| + | <code><<set $pants = "large"; $shoes = "huge"; $spats = "classy">></code> | ||
| + | ====A note about <<set>> and links==== | ||
| + | |||
| + | It is easy to assume that the placement of links in a passage has some bearing on what the game's variable state will be once you click it: | ||
| + | <code> | ||
| + | /% The following code is ineffectual %/ | ||
| + | <<set $lamp to "red">> | ||
| + | [[The lamp is red]] | ||
| + | <<set $lamp to "blue">> | ||
| + | [[The lamp is blue]] | ||
| + | </code> | ||
| + | But this is erroneous! All of these [[<<set>>]] macros are run as soon as the passage is displayed, in order. Clicking the "The lamp is red" link won't cause the <<set $lamp to "blue">> tag to not have happened. | ||
| + | |||
| + | To achieve the desired effect in the above passage, you should use [[link|setter links]]: | ||
| + | <code> | ||
| + | [[The lamp is red][$lamp = "red"]] | ||
| + | [[The lamp is blue][$lamp = "blue"]] | ||
| + | </code> | ||
