Mask with Alpha fade not working

programming flash
1

I have this problem where i will put an image on one layer over 15 frames, then on the top layer i will draw a square, make it a symbol, tween it over 15 frames with the shape tween with the alpha set to 0% on frame 1 and 100% on frame two, and i set that to mask and when i test the movie, it just pops the image up without the alpha tween acting as a mask. Am i doing something wrong? As far as i know this should work, but it’s not.

Thanks for any help offered.

Pretty sure you can’t use alpha tweens with masks…sorry, hope someone has a better idea for you :wink:

Adam’s right–you can’t change the alpha of a mask…which sucks.

There is a way of doing this, this is assuming i know what your talking about.
Make a mc with the image spanning over 15 frames, with a layer on top of that which is only an alpha tween.

on the main stage, above the mc, you put a mask, and then just make the mask have a shape tween.

I hope i’ve helped

If you convert it to Symbol, how do you Shape tween it? or if you didnt conver it…you tween the alpha…???
here is my solution

  1. place the image as required.(layer1)
  2. insert a layer above the Layer1.(layer2)
  3. place the shape tween on the layer.
  4. Insert another layer between Layer1 & 2
  5. draw a big rectangle which is larger than the shape tweening area. and Convert to Symbol. then tween the alpha.
