Populating an array with a random sequence

[jinxtengu]

Hi, I'm still working on games using Z game editor . I've recently upgraded to the newest version, but I am still going to finish my old projects using the versions they were made with originally.

Anyhow, I'm interested in learning how to populate an array with a random sequence of numbers, but importantly I don't want it to repeat any of the same numbers twice.
I was wondering if someone could show me how to write a small piece of code that would perform this function. It would help me alot and I would greatly appreciate it!!

Hi jinxtengu,

I'm interested in learning how to populate an array with a random sequence of numbers, but importantly I don't want it to repeat any of the same numbers twice.

There are quite a few ways to do that, but here's one simple approach:

Code: Select all

<?xml version="1.0" encoding="iso-8859-1" ?>
<ZApplication Name="App" Caption="ZGameEditor application" FileVersion="2">
  <OnLoaded>
    <ZExpression>
      <Expression>
<![CDATA[//

int[10] numbers;

// Fill array with sequential values

for(int i=0; i<10; i++)
{
  numbers[i] = i;
}

// Shuffle values around

for(int i=0; i<10; i++)
{
  int b = rnd()*10;
  int c = numbers[i];

  numbers[i] = numbers[b];
  numbers[b] = c;
}

// Output values

Print.Text = "";

for(int i=0; i<10; i++)
{
  Print.Text += intToStr(numbers[i]);
}]]>
      </Expression>
    </ZExpression>
  </OnLoaded>
  <OnRender>
    <RenderText Name="Print" Text="2857306149"/>
  </OnRender>
</ZApplication>
