Hello everyone !

I found a way to fade out a morph via the BitBlt class. Problem is with the code line "(Duration seconds:1) asDelay wait." When this line is present, i don't see the intermediary states, only the final result. But i need wait time at each iteration of BitBlt copyBits, precisely to visualize the fading out ...

see code below.

this should probably done in the stepping of the morph.

Thank you very much for any help ...
