actionscript 2.0 for-loop logic problem
Dear All,

I am using Flash 8 and actionscript 2.0 to load a photoWall into moviescript.
While the script runs smoothly if I separate the inside i-loop into 4 blocks.
Or some of the images will be missed. Did I missing something in logic?

Thanks in advance.
Simon

I can't see what's wrong with the code at this point. It looks good.

You should put your code in code tags, by the way.

Problem resolved
Hihi!

I have resolved the problem:
There were 2 problems:
1. Since there is depth consideration in flash, the depth variable have problem. Some photos will be overlapped.
2. I have swapped the thought of column and row so that the image is missed if I combine the code together.

Hope this can set an opp. example.

Thanks!
Simon

  4. 		photoWallImg = photoWallMC.attachMovie("xternalImageMC", "xternalImgMC_"+j+i, k);

  5. 		bigImgHolderMCL.loadClip(mainImgURL, photoWallImg);

  6. 		photoWallImg._x = 85 * i;		

  7. 		photoWallImg._y = 85 * j;		

  8. 	}

  9. }

Summary of problems for all reference
Thanks, you are so nice!

Summary of image not load problem for reference:

1. movieclip name (the name inside script mismatch with the name of Mclip)
2. image path is not correct
3. depth checking(the result is weird if depth have problem)

whenever doing a complex scripts, return and make a simple script
as a testing probe. Hope this can save you from hours of frustration.

Cheers
