I need to create a gradually fading block of dots/"X"es covering a stimulus and as the dots slowly fade away, the stimulus become visible.
I tried created a transparent animated GIF as attached. But when i input them into Excel, it can't appear simultaneously with the stimulus. So the final effect i had was this gif appearing first afterwhich the stimulus appears. this is my code for the mask:
Code:
_mask.gif (400x75)0,.4,03000*~Abused stray cats on street.0,.4,0rt:57*
Any idea how i can get this to work?
Thanks a lot in advance for help! =)
