Hi folks, I was wondering if there is a way in ChoiceScript to raise an exception so that an error is produced when a certain line is reached? Had a look on the wiki and the help files but it seems if this exists my google-fu is lacking.
I currently have this, where if a variable is not set it puts a message in the text itself, but I would like it to produce an issue and fail automated tests if the variable is not set.
#I ask for a coke.
*if alcohol
Even though you usually drink, you don't feel like it this evening.
*goto pepsi
*elseif not alcohol
As you don't drink, you order a coke.
*goto pepsi
*else
Error! Alcohol var not set!
*goto pepsi
Looking a little more closely at your example – you’d want if not(alcohol) rather than if not alcohol. ChoiceScript will interpret the latter as having something to do with a variable called not (which you probably haven’t created – and shouldn’t! Best not to confuse editors, playtesters, and yourself with code like if not or if not(not)…)
And in cases like this where you’re using a Boolean (i.e. true/false) variable, you don’t need the safety net – you could just use *if alcohol and *else, no *elseifs needed, since the variable only has two possible states. When you *create the variable alcohol, you’re creating it to be either true or false; there’s no third “not yet set” option that hangs around until you first use the variable in the game.
If you’re using a numeric or string variable, then *else and *bug can be useful to catch game states that shouldn’t be possible yet. But for that you’d need something like if alcohol > 0 or if alcohol = "wine", not just if alcohol.
