## Multiple "if / then" in script doesn't work

9 months ago

I've tried to add a script to a link, but it doesn't work. The goal is, when the player clicks on a link, a variable change : from 1 to 4, 2 to 1, 3 to 2, 4 to 3 (but the player remains on the same page). So i've written that in the script:

IF %VARIABLE1 = 2
THEN %VARIABLE1 := 1

IF %VARIABLE1 = 3
THEN %VARIABLE1 := 2

IF %VARIABLE1 = 4
THEN %VARIABLE1 := 3

IF %VARIABLE1 = 1
THEN %VARIABLE1 := 4

It works… except for "2 to 1"! Instead, the 2 goes to 4.

Why? And how to fix this?

I can't test it right now but I'm guessing that the first check sets it to 1, then the last sees that it's 1 and sets it to 4. Try changing the order?

Indeed! I moved "2 to 1" to the end, and now it's "3 to 2" that doesn't work… It looks like the first one is always skipped!

Well not so much skipped as replaced. It just checks each of them in order, the variable is getting changed twice.

Is there some way to avoid this?

It looks like you're just moving the number over by one, so try this:

%VARIABLE1 = %VARIABLE1 - 1

IF %VARIABLE1 = 0
THEN %VARIABLE1 := 4

Glad my tactic of stalling until somebody else showed up worked out.
