In this http://www.VideoFort.com After Effects Pac-Man tutorial series VideoFort Jon gives a in depth looks at motion graphics and layering, teaching how to recreate the classic Atari game, Pac-Man. In Pac-Man Part 6 VideoFort Jon shows you how to change the ghosts for when Pac-Man eats a power up. Drag the “BoardandCharacters.png” into the Game comp, pre compose it and mask the blue and white ghosts. Layer them on top of one another( should go: blue 3, blue 4, white 3, white 4) and set the first keyframe at the beginning of the comp for the opacitiy at 0%. From there determine when Pac-Man eats a Power Up pellet (the larger dots). Once you have determined when Pac-Man eats the Power Up go one frame before and set another opacity key frame at 0% for you ghosts. Then move one key frame forward and bring the blue ghost with 3 leg up to 100% and the white ghost with 4 legs to 100%. Make the 3 legged blue ghost’s opacity increase and decrease between 100% and 0% for 16 key frames. Then bring up the 4 legged blue ghost’s opacity up to 100% and set a keyframe for 0% one frame before. Now copy and paste opacity keyframes from another ghost’s (Blinky, Pinky, Clyde…) movement. once you have the blue ghost moving around for about 2-3 seconds have it flash back to normal by copying the 100% to 0% keyframes on the 3 legged blue ghost and pasting them at the end of the walking opacity keyframes. Now copy and past these ghost layers into the other ghosts comp and all the ghosts should change when Pac-Man power ups!
