Folder Picture Output

[kartikitrak]

How do you output all the pictures in a specific folder?

Basically I want to show a list of all my maps that are in a folder, however I don't know how. It's like Call of Duty when you are selecting a map.

If possible, just a list of all the filenames are good,too.

Also the folder may be updated at anytime and I would like to keep the list updated.

I think familiarizing yourself with dirmodule is a good starting point

[kartikitrak]

you have made me feel like an idea... THANK YOU! : )

[kartikitrak]

I have tried using the dirmodule however I am just wondering if it will allow you to output all the pictures in the folder.

[Tony]

It provides the tools for you to find out what all the files in the folder are. You can use file name endings to figure out if those files are pictures or not, and once you have the name of the pictures, you can do whatever you want with them.

i still don't really get it.

So how to i get the pic.draw feature to use the filenames listed in the screen

[Tony]

before you use Pic.Draw you need to use Pic.FileNew, which requires a filename, which you just got

[kartikitrak]

but does filename represent only one file or the whole list

if it represents one how would you pic.filenew the others
also if it represents the whole list would u just need

pic.filenew (filename)

[Tony]

No, Pic.FileNew take one name at a time. To go over all of the names, you'd need some sort of a loop.

anyway..i tried with just one picture but i gives me a illegal picture id number 0

var streamNumber : int
var fileName : string
var dir : string
dir := Dir.Current + "/usermaps"
streamNumber := Dir.Open (dir)
assert streamNumber > 0
loop
fileName := Dir.Get (streamNumber)
var pic : int := Pic.FileNew (fileName)
exit when fileName = ""
put fileName
Pic.Draw (pic, 0, 0, picCopy)
end loop
Dir.Close (streamNumber)

[Tony]

What is the fileName that it tries to open? Is there such a file in the _current_ directory?

[kartikitrak]

My current directory

/Game
listprogram.t(this is the program)
/usermaps/pic1,pic2

[kartikitrak]

Do you have an msn. So we can talk via msn.

[Tony]

Yes. When you get the illegal picture ID error, what value does fileName have at that time?

[kartikitrak]

if you didn't get the folder...

the directory that everything is in is: Gane

in that folder there is one folder named usermaps and the turing file.

the turing file is trying to read and output the pictures in the usermaps folder.
