through symbol?

[Grimsin]

how do you do number ranges? can i do this

targetlvl = UnitLevel("target")
if targetlvl == 1-9 then
blah blah blah

does that then allow it to respond if the result is 1-9?

[Akryn]

That would result in -8 (1 minus 9). What you want is:

if targetlvl >= 1 and targetlvl <= 9 then

or

if targetlvl > 0 and targetlvl < 10 then

[Grimsin]

has to be 0 if you use 1 it does not do what its supposed to when targeting a lvl 1.

thanks though that is exactly what i needed.

[Seerah]

There's no such thing as lvl 0, so you only need

if targetlvl <= 9

[Grimsin]

wait maybe im reading it wrong, when you do the <= or >= does that mean greater/lesser then or equal to?

-- edit: what i mean is... does >= mean "greater then and equal to" ?

[Grimsin]

it does mean that, well the and should be and/or but, akryn was right on both of them. and 0 does have to be used on the 2nd one 10 has to be used on the < side. or when you target a 9 it does not do its thing...

[Seerah]

Right. Because 10 is not less than 10. But there is no reason why you should bother computing if the level is greater than 0 because there *is* no level 0.

One calculation > two calculations.

[Grimsin]

ah i see so dont use the greater then 1 or 0 at all.

[Grimsin]

is there a way to do not = to a number? so lets say

or max mana...

if currMana ~= # then
do somthing

[Seerah]

Yes. ~= is "not equal to" in Lua.

*facepalm me*
well at least that answers how to do it in the future if it comes up again.

Edit: Although, actually, if you target nothing it will error as it is now, so depending on the situation that this is being used for you could still use it like...:

targetlvl = UnitLevel("target") or 0
if targetlvl > 0 and targetlvl < 10 then
...

yea i had to put if unitexsists in it to stop that.

[Seerah]

if UnitExists("target") and UnitLevel("target") < 10 then
     --do stuff
end

/edit: or...

targetlvl = UnitLevel("target")
if targetlvl and targetlvl < 10 then
     --do stuff
end

might be better, since it's only function call.

[Recluse]

You really need to add in the check for '> 0' or '>= 1'.

When you request UnitLevel on a raid boss or an opposing faction player / mob 10 levels above you, UnitLevel returns '-1'. Because of this you'll need to compensate for the possibility.

if UnitExists("target") then
     local unit_level = UnitLevel("target")
     if unit_level > 0  and unit_level < 10 then
          -- Handle units level 1-9
     end
end

[Seerah]

Ahh... Totally forgot about that, since I only use UnitLevel() to check to see if I should gather talents from players.
