I'll be the judge of that lol.
Put it this way, if you know about variables, arrays, instance names and attachMovie then this should be easy enough. If you don't then head here and brush up:
viewtopic.php?f=10&t=345First make 4 movie clips, for this example we will use Mario, Luigi, Wario and Waluigi. In the library give them the instance name of their actual name in small caps.
This code will make the characters appear on the stage.
If you want the use to be able to choose characters you will need to allow them to change what's in charArray before calling the for loop.
