[Trigger] Find the lowest value

[Megafyr]

Let's say I got five real variables with different values. Is there a formula to detect the variable with the lowest value?

i think you have to check whether every value is smaller than the other ones.
so it will be a huge 'if then else' function

set them in an array variable
(Array[1] = Value1, Array[2] = Value2... etc)

local integer Lowest = 100000000000000000000000000 // Make this BIGGER than the biggest value
local integer MaxIndex = 5 // Your amount of values
local integer Index = 1
loop
    exitwhen Index > MaxIndex
    if Array{Index} < Lowest then
        set Lowest = Array{Index}
    endif
    set Index = Index + 1
endloop

({Index} = [Index]
Because JASS tags are fucked up ATM)

Placing the lowest value as "Min" and Maximum as "Max" (Maths function) and then an if/then/else that detects where the current value belongs?

just corrected a few small things on Yixx's post. remember that arrays start with the index 0, and the amount of values in the array is not the same as the biggest index (usually amount of values = biggest index+1 unless you store stuff in random indexes)

local integer Lowest = Array{0} //this is more efficient and i think that number you put in is greater than the biggest integer allowed
local integer NumValues = 5 // Your amount of values
local integer Index = 1
loop
    exitwhen Index >= NumValues
    if Array{Index} < Lowest then
        set Lowest = Array{Index}
    endif
    set Index = Index + 1
endloop

({Index} = [Index]

Uhm ... I still pretty much suck at jass. What would I have to do if I want to use that detection system after these actions? : >

• Actions
  • Custom script: local integer a
  • Custom script: local rect r
  • Custom script: set r = Rect ( 0, 0, 0, 0 )
  • Custom script: set a = 2048
  • Set tmp_loc = (Position of Player[(Player number of (Triggering player))])
  • Custom script: call SetRect ( r, GetLocationX(udg_tmp_loc) - (a * 0.5), GetLocationY(udg_tmp_loc) - (a * 0.5), GetLocationX(udg_tmp_loc) + (a * 0.5), GetLocationY(udg_tmp_loc) + (a * 0.5) )
  • Set tmp_group[1] = (Units in tmp_region matching ((Owner of (Picked unit)) Not equal to Player 5 (Yellow)))
  • Set tmp_integer = 0
  • Unit Group - Pick every unit in tmp_group[1] and do (Actions)
    • Loop - Actions
      • Set tmp_real_array[tmp_integer] = (Distance between (Position of Player[(Player number of (Triggering player))]) and (Position of (Picked unit)))
      • Set tmp_integer = (tmp_integer + 1)

tmp_real_array are the values I want to check.

I want to detect which units is closest to player which is a unit.

Integers can't sore any value above 2^31 - 1 (2147483647)

Signed and 4 byte*

 

[Eleandor]

integer is signed 4 byte int...

 

[baassee]

@topic

check the value by going with a loop and if / then / else checking the reals thought there might be alot of loops

@off topic

reals store alot more then integers

He wrote Integer. :>

What's the chance that we talk about an 8 byte int on this forum?
