What does 'static' do?

12-31-2009, 10:26 PM	#1
thehellman	I tried looking through JASSHelper but I still don't quite get what the term static does in a struct. In normal programming it means like makes the entire program have access to that method/variables. But I'm confused it's purpose in a struct. If anyone would be so kind as to tell me when it comes in handy?

thehellman	I also have 2 other unrelated questions: 1) What's the best way to keep a units health at 1 (such as disabling health regeneration) and without the use of a timer. 2) Do item abilities stack? (Example, if I put on Item Armor Bonus that adds +4 armor, if I add another ability off the same base Item Armor Bonus, but instead it -4 armor, will the net result be 0 armor gained)

It designates a specific character as static; they cannot undergo character development for the course of the novel.

???:

struct X
   static integer INT = 0
   integer int = 0
endstruct

function yessa takes nothing returns nothing
 local X this = X.create()

   set this.int = 7
   set X.int = 7
   set this = X.create()
   set this.int = this.int - 6
   set X.int = X.int - 6

   call BJDebugMsg(I2S(this.int))   // prints "-6"
   call BJDebugMsg(I2S(X.int))   // prints "1"
endfunction

A better way to explain:

struct Wat
   static integer N
   integer count
endstruct

// Compiles - >

globals
    integer s__Wat_N
    integer array s__Wat_count
endglobals

Static makes it essentially a global with the STRUCTNAME.<blah> prefix. It's not instance specific. There's only one.

Wikipedia: Class variable
Yahoo Answers: What's the difference between static and instance members?

You can stack item abilities if they are different abilities;

Example:

Ability A (+4 armor)
Ability B (+4 armor)
Ability C (-4 armor)

A + C = 0
A + B = 8
A + A = 4
Ax10 = 4
A + B + A + C = 4
B + B + B + B + C + C = 0

BonusMod (item abilities)

Keeping a unit from regenerating HP could be done with a -100% Unholy Aura Regen, but keeping a unit's HP at exactly 1 is an entirely different thing (assuming you don't want it to die when it takes damage) and therefore DOES require a timer, or a Resistant Skin -50000 ability or Elune's Grace -100% ability. Maybe. This last one is speculation on my part because I don't feel like opening the editor.

Okay thanks. I had the Unholy Aura idea in mind but wanted some confirmation. (And no, the unit will be invulnerable so it can't take damage)

thehellman	I just tested it. It's actually killing the unit, and causing an infinite loop. It's set to -1.00 and percent bonus is on true.

Themerion	Why wouldn't you want to use timers...? Anyway, if you can store the unit's current max hp, you can use .: UnitMaxState :. to set its max hp to 1 (then reset it to the stored value at will).

thehellman	Yeah I ended up using a timer for this. Thanks for the help /close
