Zombie Movement Diagram

So what I did for this diagram was I made 3 separate flowcharts and meshed them together. I started with the patrolling, then I did the chasing, and finally I did the attacking. I connected the chasing and attacking first so that they would flow naturally together. And then I connected the chasing chart to the patrolling chart for if it's false. Finally I had to use logic to figure out what would happen if the enemy kept moving and the player walked by it. I added another decision for if the enemy sees the player it would go back to the enemy chasing the player and if it didn't then it would just continue walking.
