Damit !!! again i’m in trouble:{
A movieclip \_root.mist to be masked with the duplicate movieclips i.e \_root[“mc”+amount] but it is not working …
This is the script on the frame 1 of the movie
amount = 1;
while (amount\<50) {
duplicateMovieClip (\_root.flower, “mc”+amount, amount);
\_root[“mc”+amount].\_x= 40\*amount;
\_root.mist.setMask (\_root[“mc”+amount]);
amount++;
};
Any suggestions…thanx in advance

A movie clip can only have one mask. Put the movie clip you want to duplicate inside of another movie clip, duplicate it and then set the container movie clip as the mask. 🙂
