Im running into a few issues

hey, ive been making real simple ads for my friend for about two months now slowly getting more and more detailed but this one i tried alot of new stuff and am getting a lot of new problems. ive searched for the answers and found close stuff but havent been able to adapt it to what i need.

Problems:

  1. im not sure how to get the chainsaw to only flip directions when i am draging it.(i tried what i could think of but my bag of tricks is small)
  2. i found the code to spawn the zombies with random numbers of each and speed but im not sure how to get them on a repeating path after their there.
  3. i need a way for the hittest to register once then stop to allow me to play to death animation and get a count of how many have been killed to trigger the clicktag.(i dont have an animation for that so the currently turn black to show their out.)
    4.i dont know how to do the hittest on the spawned zombies and they are also ontop of the saw.

im sure there are more problems i havent found yet but these are the ones i could think of right now. also i may be adding alot of info you dont need but im trying to be thorough.

a lot of this is copy and pasted in there but i am taking the time to read it and really try to understand why it works the way it does. also any advice on ad making would be nice.

(the zombies will be off the screen once its done)

thanks
