The following code on page-show sets up the number of objects:

RandomList(10)
for (n=1 to RandomList)
{
eval("obj_" + randomlist[selected-1] + ".Show()")
}

and this script, spaces those objects, at random, evenly down the screen:

function RandomList(number) {
numberlist = new Array();
for (count = 1; count <= number; count++) {
numberlist[count] = count;
}
randomlist = new Array();
for (count = numberlist.length - 1; count > 0; count--) {
picked = Math.floor(Math.random()*count)+1;
randomlist[count-1] = numberlist[picked];
eval("obj_" + count + ".SetPositionY(" + ((numberlist[picked]*30)+170) + ")")
numberlist[picked] = numberlist[count];
}
}

I have been trying to edit it so that it functions in the same way, but selects the ten objects from a batch of 15 objects (obj_1 through obj_15)

and I’m tying myself in knots and getting nowhere fast.

Have tried putting in an if statement and counts to surround the above code, and also inserted it within the code at different places. Have managed to get it to show just ten objects, but they are always the objects numbered 1 to 10! I'm trying to find the programming equivalent, for me, of finding a needle in a haystack.

I would really appreciate some help on this.

Many thanks,

John

Hi John

same problem as last time

eval("obj_" + count + ".SetPositionY(" + ((numberlist[picked]*30)+170) + ")")


eval("obj_" + count +

will always give you obj_10 , obj_9 , obj_8 ...

try eval("obj_" + randomlist[count] +....

Hi Chris,

Many thanks for your response - you've lost me. I understand your ref to 'same prob as last time' - except.

The code as quoted works perfectly - pumps up the number of designated objects in random order down the screen.

What I cannot get it to do is display a random subset. So, currently it will give me for example: 2, 5, 3, 7, 9, 10, 1 etc up to the whole 15 objects. I now want to be able to display say only 10 of the objects randomly selected from all 15.

Edited: I attach an imp file that shows the 15 objects randomising each time I refresh the page. I cannot work out how to show just a random subset of, say, any ten of the fifteen. I'm repeating myself!!

Attachment here - I hope

Well - I would add an attachment but the 31K file causes the following message 'Sorry, but the maximum filesize for all Attachments is reached. Please contact the Board Administrator if you have questions.'

Stymied!
