Can pictures be used in/as an array?

-----------------------------------

I have previously asked this question and I will attempt to ask it again hoping to have some answer of some sort:

can you use pictures in an array and how can one do so?
(an example or two would be greatly appreciated...)

thnkx...

(correct me if I'm wrong...) In Turing, images/sprites aren't actually images/sprites as they are in other languages, they are just integers representing the loaded image, so you can make an array of integers, and load stuff into it:
var pics: array 0..2 of int
pics(0) := Pic.Load(...)
pics(1) := Pic.Load(...)
pics(2) := Pic.Load(...)
You can also use a loop to load them, which is probably why you want them in an array.

okie, so your help really cleared things up for me

however, when i try to get a loop to simplify things,  a problem arises in my code like so:

loop
    put qst(x)
    delay(500)
    put "A) ", OptA(x)
    put "B) ", OptB(x)
    put "C) ", OptC(x)
    put "D) ", OptD(x) 
    put ""
    Pic.Draw (pics(x), 200, 300, picCopy)  ANYONE, could figue out why my program is not working and how i could fix it, i would be most grateful...  :wink: 

thank you..

my first guess, based on the error message, is that the image is simply isn't loaded. You can check what Pic.FileNew("eye1.bmp") returns. Some common reasons is that the image name is either misspelled or the file is located in a different folder than your program is looking in.

    if picnum not= 8 then  %%% the number of frames, makes sure it done exceed

    else %%% the frame number is higher then the amount of pictures
        picnum := 1 %%% restart at frame 1
    end if
    pic := Pic.FileNew ("Images/can" + intstr (picnum) + ".BMP")
    %%% ok... that makes the picture variable change to reflect the current picture
    %%%% intstr converts interger to string so it will be can1.bmp or can2.bmp depending on the frame...
    Pic.Draw (pic, maxx div 2 - 75, maxy div 2 - 50, picCopy) %%% draws the flag in the middle of screen
    View.Update
    cls
    delay (100) %%% so its kinda smoother... u could use View.Update **i made this for simplicity..
end loop

here is a method of using pictures in a for loop taken from this tutorial

That doesn't use an array though...

thanks for all the help ideas guys... turns out that Toni was right... my pictures weren't located in the same folder as my application thus giving me that error message... 

+_+ wow, what a simpleton i was...
thankfully, i learned my lesson :)

and, my project was completed (and worked) successfully with all your help

thanks again!
