let me make myself clearer. when for example, ur on a wevsite that uses flash and ur mouse goes over an object and it causes a mini movie (if u will) to play inside the main movie instantly, this suggests that the mini movie is apart of the movie but just wasnt called for yet. How is this achieved.
note: forgive the exescive layman terminology, i couldnt think of the correct flash terms to use. (4give me im new to flash)
