If

if function

The if command is the main method of doing conditions in narrat. It can be used to branch inside a script, or to make choice options conditionally available.
if [condition]:
"This code is run on condition success"
else:
"This code is run on condition failure"
else is optional
The condition should be a boolean. You can directly pass a value (if $data.someValue ), or an expression that returns a boolean (for example if (> $data.player.age 18)

Examples

Simple example:
main:
talk player idle "Wow, I found the key!"
add_item key 1
jump tryDoor
tryDoor:
if (has_item? key):
"You open the door and get inside"
else:
"You need a key to open the door!"
Example:
main:
choice:
talk alice idle "Do you prefer pizza or buger?"
"Pizza":
set data.player.prefers "pizza"
"Burger":
set data.player.prefers "burger"
ifExample:
if (== $data.player.prefers "pizza"):
talk alice idle "Let's have pizza then"
jump havePizza
else:
talk alice idle "Let's go for a burger"
jump haveBurger
havePizza:
//...
haveBurger:
//...
