| Basically I've got a bunch of functions that go along the lines of:
function reset.drink ()
if bal.drink == .5 then
bal.drink = true
end
end
function reset.salve ()
if bal.salve == .5 then
bal.salve = true
end
end
function reset.herb ()
if bal.herb == .5 then
bal.herb = true
end
end
And so on and so forth, and I was wondering if there was anyway to condense them into one function, such as
function reset.balance (type)
this way I could save space in my script file, any suggestions? | | Top |

| Sure.
function reset.balance(type)
if bal[type] == .5 then
bal[type] = true
end
end
In Lua, for a table t, t.str is a shortcut for t["str"]. If you do t[var], that means "look up key var in table t'. |

| | Lua is amazing. Do you know if there's anyway to do that in vbscript? Because I've been trying to figure that out for a long time :( | | Top |

| I'm not terribly sure if there's an easier way to do it other than what I'm going to suggest, but there's a simple workaround I've used for a long time. Just an extra value to the function saying what variable to modify. Then just have a case section picking the variable to modify.
function reset( action )
select action
case "drink"
if bal.drink == .5 then
bal.drink = true
end
case "salve"
if bal.salve == .5 then
bal.salve = true
end
case "herb"
if bal.herb == .5 then
bal.herb = true
end
end select
end
My only concern is that the value for bal.foo has both decimal values and boolean values in there. It kind of obscures the code a bit, and is harder to follow than just a normal test of bal.foo == 1 for true. Granted, I haven't seen the rest of the script, so it might make sense to have it that way. |

It would be easy if you had arrays that could have named indexes (rather than numbers). I think there is such a thing, I can't remember offhand what it is. |
