I am not clear on exactly what you mean.. If I understand your question correctly you are just looking to click a button to move between frames to different sprites?
Are you placing your sprites on the score spanning across multiple frames? (ie- sprite one spans from frame 1-10, sprite 2 spans from 11-20..etc)
If so- one method would be to use "markers"
You could use sometihng like-
on mousedown
go to frame "*****" ( * represent your marker name )
end
-----------------------------------------------------
als0-Make sure you are using
on exitFrame me
go to the frame
end
(to keep the play head from looping)
Not sure if this will help but here it is anyway..
good luck, Red
