Challenge 3.

okay, so for this challenge, i had to get two bat sprites, one with the wings up, and one with the wings down, and i have to make them alternate costumes from one to the other, to give the illusion of flying,

for this i used this code

and it worked great.

it looked a little something like thiss.

sooo there you go (:

just click if you wanna make them biggerr.
