First of all, thank you very much for this brilliant job! I use blitmask as Carl Schooff’s singleDigit.fla example, but I’m using the button to go forward number by number and another button to choose the number user wants. When user choose a number i need to 'disable' this number coloring it in grey for exemple, or modifying its alpha level. … var blitMask1:BlitMask = new BlitMask( strip1, strip1.x, strip1.y, strip1.width, 300, true, true, 0xffff00, true); … //if user choose the number three... strip1.three.alpha= 0.5; // I want to do that but it doesn't work and I don’t know how to modify or update the target bitmap. … Thank you very much for you help! Sorry for my poor English..
