Editing Script Block (section)

== Remembering things from the last time the script was run ==

Usually the script runs a fresh each time, forgetting all its variables, but it is possible to remember things from run to run, this is done using the persistent (or p) scope. Also because I really struggle to spell persistent you can also use the persist'''a'''nt scope and that will work fine. Anything in the persistent scope will still be available the next time the script runs.
So lets say we want to modify the “go away” script from the “asking questions” section so that if starts saying go away if you come within 5 meters but then it keeps saying it until you are 10 meters away:


<pre>if(firstRun){
    p.goAway = false //when the script first starts up default to not saying anything
}

if(W<5){
    p.goAway = true 
}
if(W>10){
    p.goAway = false
}
//note that if W is between 5 and 10 it is left at whatever value it had previously

if(p.goAway){
    N = 'Go away!'
}
</pre>
