[WEAKAURAS] Need help with snapshotting health in LUA

[peterparker]

Hi,

so this is my problem. I have created this if statement (just copied 1 line from it, cause you dont need more to understand it), but its not working the way I want it too. This is my current statement:

if (UnitHealth("player") == UnitHealth("player")) then

What I want to achieve is something like the statement below where it snapshots the current health and compares it to the current health.

if (UnitHealth("player") == SNAPSHOT_CURRENT_UnitHealth("player") then

Is there a simple way to do this with some variables? Or does anyone have a smart solution to this problem?
Thanks in advance!

That doesn't make sense to me. Elaborate please.

*evn, thanks buddy, problem solved! I thought saving (UnitHealth("player") in a variable would dynamically update the variable aswell, but it doesnt

*Woogs, this is what I really was trying to do (I simplified it a bit):

if Touch of karma is up and I am not taking any damage
show percentage of how much damage I am taking compared to my current max health

elseif touch of karma is up and I am taking damage
show message "danger"

to check if I was taking damage or not I couldnt use if (UnitHealth("player") == UnitHealthMax("player")) then, because UnitHealthMax only showed my max total health (100%), regardless of the fact if I had 90% health at that moment. So what i wanted to store this 90% health somewhere and compare it to my updating current health.

A closure would not be ideal for what you describe because there is no need to store an internal state. Your example using a ternary statement in Lua syntax:

foo = function() return UnitHealth("player") > UnitHealth("target") and UnitName("player") or UnitName("target") end
