Fellow Flashers,

I'm looking to assemble a random image generator that will:
1) load images externally
2) have a reload button that loads the next random image

I know this is probably pretty easy to assemble but i am juggle 3 other flash projects and cannot donate the time. If anyone has a .fla file or code I'd be in your debt.

thanks much!!!

I haven't tested it, but this should work

ActionScript:
pic_arr = ["images/1", "images/2", "images/3", "images/4", "images/5"];
one_btn.onRelease = function() {
        ranNum = Math.floor(Math.random()*pic_arr.length);
        holder_mc.loadMovie(pic_arr[ranNum]+".jpg");
};

ok this is great. I typod the name of the holder_mc, empty movie clip wrong (duh).

is this a TRUE random loader? seems that the same image can pop up more than once in a row.

but this is real good. thanks a TON!!!!!!!!!!

well.. it's not a problem to test if the newly generated image that is about to be loaded is the same or not.. and if it is then just go back one step and generate a new..
hope this makes sence

shpek,

It will be random, but it is a crude way of doing it.
Cos it is random, you could get the same number twice
You could to it so it picks random images but only picks them once, so the images wont repeat, if thats what you want.

hey coop,

this will actually work but I was going to push it a little further so that each random load would not re-load or repeat the same image consecutively.

thanks again!

Ah i just re-read it. i didint have my coffee yet

The way it is will actually work fine. I was wondering if I should build some type of prelaoder into it but I'm not sure its necessary and actually not sure how to build a preloader into an array like that so it will work dynamically with the random image loading though...

what's the problem? what code do you use to actually LOAD the image?

I'm guessing that there is a function that generates a name of the file from an array at random, then it sends this name to the load-function which in it's turn LOADS the file... so what would happen if you put a preloader-code inside that load-function?

Is there anyway to attach a url to the images? Also, I wondering if you can display 8 images instead of 1?

I'm pretty sure there is. I wonder if using an array would work. Each image would have an ID. That ID would be part of the array. Once an ID is established for each image I believe you could attach a URL to each image.

That sounds like it would work, but I don't know the coding to do it...

One way would be to use an array of objects:

ActionScript:
picArr = [
{ image: "image/1.jpg", url: "http://www.flashdevils.com/"},
{ image: "image/2.jpg", url: "http://www.macromedia.com/"},
{ image: "image/3.jpg", url: "http://www.microsucks.com/"}
];

ActionScript:
rnd = Math.floor(Math.random()*picArr.length);
item = picArr[rnd];
itemImage = item.image;
itemUrl = item.url;
// etc

{ image: "image/2.jpg", url: "http://www.macromedia.com/"},
{ image: "image/3.jpg", url: "http://www.microsucks.com/"}
];
one_btn.onRelease = function() {
        ranNum = Math.floor(Math.random()*pic_arr.length);
        holder_mc.loadMovie(pic_arr[ranNum]+".jpg");
};

ActionScript:
picArr = [
{ image: "image/1.jpg", url: "http://www.flashdevils.com/"},

one_btn.onRelease = function() {
        ranNum = Math.floor(Math.random()*pic_arr.length);
        holder_mc.loadMovie(pic_arr[ranNum]+".jpg");
        rnd = Math.floor(Math.random()*picArr.length);
        item = picArr[rnd];
        itemImage = item.image;
        itemUrl = item.url;
        // etc

your second code looks like it should as far as I understand.. but what do you mean by 'displaying 8 pictures'? you want to have 8 holders and then each time a buttons is pressed all holders are updated and each and one of 'em loads a random picture?

Yes that's correct. Here's a pic to show what I want:

http://img176.imageshack.us/img176/...rtlayout0yz.jpg

I tried the last coding, but it gave me this message:

"Error opening URL "file:///C|/Documents%20and%20Settings/Cody/My%20Documents/.jpg""

I made a folder in my documents, that says image and when load the the original swf, it works, so what should I do?

well.. first of all - your declaired array's called 'picArr', but you're calling a 'pic_arr' that's why you don't get any filename there.. otherwise the code is correct.. to avoid such errors you should learn trace-debugging..
basically what you need to know is how to locate crucial places in your code and put a trace() command there to output something in the Output-panel...

like in this code of yours.. you should have already understod that there is something wrong with the array just by reading the file-path.. as you see the NAME of the jpg is missing, that means pic_arr[ranNum].itemName doesn't exist
but if you put a trace command let's say here:

ActionScript:
// ...CODE...
item = picArr[rnd];
trace(item);
itemImage = item.image;
itemUrl = item.url;
// ...CODE...

you will get a 'undefined' in the output-panel.. which means that the current object does not exist or is undefined...
it's a very easy and VERY VERY handy way to debug your movie.. I've never used the built-in debugger

second....
8 images.. first of all I'd like you to get ONE of 'em working.. after that you can just call the same piece of code 8 times for different holders... it's up to you to decide how you want to do that, with a function of a for-loop... just make ONE working and the other 7 are gonna be easy

I put the trace command in there but now I get this error:

Error opening URL "file:///C|/Documents%20and%20Settings/Cody/My%20Documents/[object Object].jpg"

what should I do now?

What code are you using to load in the image? My guess is yer trying to load in the object and not the property inside the object that holds the image/file-name.

ActionScript:
holder_mc.loadMovie(picArr[ranNum]+".jpg");

ActionScript:
item = picArr[rnd];
itemImage = item.image;

Sweet I got it to work. Now if I have a site has that has the same front link, like: http://img.photobucket.com/albums/v727/tivaelydoc3/

and if address the images as 1, 2 , 3, etc, what coding should I change:

ActionScript:
picArr = [{image:"image/1.jpg", url:"http://www.flashdevils.com/"},
{image:"image/2.jpg", url:"http://www.macromedia.com/"},
{image:"image/3.jpg", url:"http://www.microsucks.com/"}];
one_btn.onRelease = function() {
        ranNum = Math.floor(Math.random()*pic_arr.length);
        item = picArr[rnd];
        itemImage = item.image;
        holder_mc.loadMovie(itemImage);
        rnd = Math.floor(Math.random()*picArr.length);
        itemUrl = item.url;
};

you shouldn't change anything.... the only thing you need to change in this code now is the path to the jpg and the link that's it!
btw.. I couldn't get to that link of yours coz one need a password =|

well, as soon as i get some pics uploaded, its just going to be that adress and 1.jpg, 2.jpg, etc. So, instead of image/1.jpg I would the url with the 1.jpg at the end?

exactly... image/1.jpg means that there is a map in the same directory where your swf is called "images" and that 1.jpg is inside of that map... so if this is not the case in your folders make sure you insert correct path there
