Howdy.

Thanks to Shaedo, I was able to simulate a 4 x 4 pixel grid on the stage where users can plot 4 x 4 pixel dots. I’ve also added a color picker.

I’m trying to figure out how to make each and every dot that’s created permanent. By this I mean no new dot can be drawn on top of one that’s already been plotted.

I’ve attached a copy of the .fla and .as for anyone who’s willing to give me a hand with this.

Your time is much appreciated.

Best,

Mike
