Hi. Lately, I've been spending hours trying to get this to work, but for whatever reason it is just not running correctly. Basically, what I'm doing it having a variety of timers going off to signal when the enemy is supposed to move. It's supposed to go down at a random time, let out a beam for a short pause, and then go back up. I've been able to get it to go down and shoot the beam, but it gets stuck there and won't move up. I've discovered that the bolded line is where the program is stopping:
That certain code is only one of the many different attempts I've made to get it to work, it seems like no matter what I do it won't go past there. I've discovered that everything around this code works, as when I change the values to set timer4 to 150, the code runs. It's just when I have the timer3 code that is supposed to remove the beam and make timer4 = 150, it just doesn't run.
If you need anymore information to help, I'm open to give some.
