Random numbers from a pool of numbers.

Hey everyone,

A quick question, I'm sending CC message from a StepSlider. I have 37 values possible for each slide. I'm looking for a way to randomize a selection of values. So for example I would need the values {3, 10, 15, 20}
to be randomized across the sliders on a button press Then on the next button press it would be {10, 20, 3, 15}.
I've managed to randomize the sliders on one hand and to apply a selected pool of values on another hand, but can't figure out yet how to link the two.

If anyone has an idea, I'm all ears

Thanks all.

This can be done with a very simple shuffle "algorithm"

// Values is the array of values to be shuffled
decl index = sizeof(values); // Get the index of the last element
decl random, temp;

while (0 != index) { // Loop until every element has passed this loop
	random = floor(rand() * index); // Create a random index
	index--; // Decrease the current index

	temp = values[index]; // Store the value add 'index' in a temp value
	values[index] = values[random]; // Set the value add the random index in the 'index' slot
	values[random] = temp; // Insert the stored value in the random slot
}

return values; // Return the values

I hope my comments make the thing a bit clearer. I've attached a sample file so you can see the implementation

And as always, just let me know if you don't understand anything;)

thanks.

Nice one MrCobra - it does the trick spot on!

I must says I'm not getting the all concept yet but I'm studying it to understand what's going on exactly:)

thanks a ton!

Cheers
