as2 dynamically change flash movie clip colour onRollover

Hi I have a flash开发者_如何转开发 map of the world onRollover a region changes color onRollout changes back no probs BUT I dont want to tween these as my flash file is massive

Can any point me to a tutorial or have any ideas at all.

I cannot do buttons as i need smooth transition also between rollover and rollout.

I have trawled the net and have found nothing to help me in as2.

I really would appreciate any help at all - miss_j2000

To do tweening programatically in AS2, you use the Tween class. There's a good tutorial on Kirupa on how to use it.
