Hey i was researching an idea which lead me to create this script to test a concept.

The script uses random to generate a random number, and depending on the number, it will add or subtract a set amount from a variable that started out as 0.

So far I've had it open for like 20mins, and I can't get the number to get higher than 5 or lower then -5.

Basically it only goes from -5 to 5 and inbetween.
Why is this?

Here is the script.

Code:

count=0
gui, add, text, h20 w200 vin, 0
gui, show, Ticker
settimer, check, 450
return

check:
gui, submit, nohide
count=%in%
random, ran, 1, 10
if ran=1
{
envadd, count, 1
guicontrol,,in, %count%
return
}
if ran=2
{
envsub, count, 1
guicontrol,,in, %count%
return
}
if ran=3
{
envsub, count, 5
guicontrol,,in, %count%
return
}
if ran=4
{
envadd, count, 2
guicontrol,,in, %count%
return
}
if ran=5
{
envsub, count, 2
guicontrol,,in, %count%
return
}
if ran=6
{
envadd, count, 3
guicontrol,,in, %count%
return
}
if ran=7
{
envsub, count, 3
guicontrol,,in, %count%
return
}
if ran=8
{
envadd, count, 4
guicontrol,,in, %count%
return
}
if ran=9
{
envsub, count, 4
guicontrol,,in, %count%
return
}
if ran=10
{
envadd, count, 5
guicontrol,,in, %count%
return
}
return

AFAIK the random generator creates equidistributed numbers.
So all your if-blocks get a 10% chance of execution.
And there is always a matching add-block for each subtract-block.
So each block reverses the impact of another block. Your number should always stay around 0.

more variation but still swinging around 0:

Code:

number := 0
min := 0
max := 0
avg := 0
R_Index := 0
positiv := 0
negativ := 0
Random, randold, 1, 10
loop
{

   Random, rand, 1, 10
   if (rand < randold)
   {
       Random, rand2, 1, 10
       number += rand2
       total += number
      R_Index ++
   }
   if (rand > randold)
   {
       Random, rand2, 1, 10
       number -= rand2
       total += number
      R_Index ++
   }
   if (number > max)
      max := number
   if (number < min)
      min := number

   if (number > 0)
      positiv ++
   if (number < 0)
      negativ ++

   avg := total // R_Index
   
      
      
   Tooltip, Number: %number%  || Avg: %avg% || Min: %min% || Max: %max% ||`n`n Iteration: %R_Index% || Larger_0: %positiv% || Smaller_0: %negativ%
   randold := rand
;   sleep 20
}

actually I appended it a bit and it seems to go random now.

Here's the source.

Code:

count=0
gui, add, text, h20 w200 vin, 0
gui, show, Ticker
settimer, check, 450
return

check:
random, ran, 1, 10
if ran=1
{
envadd, count, 1
guicontrol,,in, %count%
return
}
if ran=2
{
envsub, count, 1
guicontrol,,in, %count%
return
}
if ran=3
{
envsub, count, 5
guicontrol,,in, %count%
return
}
if ran=4
{
envadd, count, 2
guicontrol,,in, %count%
return
}
if ran=5
{
envsub, count, 2
guicontrol,,in, %count%
return
}
if ran=6
{
envadd, count, 3
guicontrol,,in, %count%
return
}
if ran=7
{
envsub, count, 3
guicontrol,,in, %count%
return
}
if ran=8
{
envadd, count, 4
guicontrol,,in, %count%
return
}
if ran=9
{
envsub, count, 4
guicontrol,,in, %count%
return
}
if ran=10
{
envadd, count, 5
guicontrol,,in, %count%
return
}
return
