| I'm trying to make on key in my table(of numerical values) be a specific number less than another. Here's what I wrote..(doesn't work).
function calculate_stats()
ArraySet ("stats", "siphp", "(ArrayGet ("stats", "truemaxhp) -350)")
note (ArrayGet ("stats", "siphp"))
end
What I want is to make the siphp key 350 less than the truemaxhp key.
Thanks! | | Top |

| Your quotes are a bit strange. You have quoted "(ArrayGet ..." which means it is just a string, not a function that will be called. Also you don't close the quotes for "truemaxhp) .
Last, the function is Note not note (note capitals).
This will work better:
ArraySet ("stats", "siphp", ArrayGet ("stats", "truemaxhp") - 350)
Note (ArrayGet ("stats", "siphp"))
However even this will fail with "attempt to perform arithmetic on a nil value" if you don't put a numeric value into the "stats" array item initially (to say nothing of having to create the array before you do that).
My full test, which worked for me was:
ArrayCreate ("stats")
ArraySet ("stats", "truemaxhp", 10)
ArraySet ("stats", "siphp", ArrayGet ("stats", "truemaxhp") - 350)
Note (ArrayGet ("stats", "siphp"))
