Hi. I'm putting together a revision/school app. I'd like to be able to read from a .txt or .csv file to easily edit a layer that appears as information. When an image is clicked I'd like to bring up a picture and/or layer that has a block of text from the file. The amount of text will change so if the block of text is large I will also need to be able to "flick" the image up and down only to read the text. I hope this makes sense.

Thanks in advance.

Baxslash posted code to do this here

Thank you for the link. I have learned a lot about text and readline commands over the past few days trying to find the best solution.

The script from baxslash certainly is better than just using text on a background, the quality of the text appears very good. Though I keep having a problem with the function deleteTextBox() with gives an error with the "Subscript is out of bounds at line" marked with ##

+ Code Snippet

function deleteTextBox()
    deleteSprite(box.bg)
##  for i=1 to box.numlines  ##
        deleteText(boxText[i].ID)
    next
    dim boxText[0] as boxTextType
    if box.max>box.height
        deleteSprite(box.scrollbar)
    endif
endfunction

for i=1 to box.numlines

I have not done anything different with the code. All functions are included in an extra file #include function.agc

if anyone else has any suggestions they too will be greatly received.

This:

for i=1 to box.numlines

should be:

for i= box.numlines to 1 step -1

(otherwise, by the time you are half way through the deletions, you are trying to access an index that has already been deleted).

Thank you BatVink. I really like the idea and the maths behind the half way through issue. However there was another issue with the text and box being removed but the scrollingtext still be present. The use of a new textshown as integer 0 or 1 added to the code made a big difference.

I will continue with this!
