Using raycast to evaluate decisions
Ideally, at the start of the turn, the character has two raycasts, one for his left side and another for the right side. This will check if there's a wall obstructing one of those directions. This can be used to determine what side the character should be moving toward if he wants to protect himself from being attacked. Then, we would use another raycast in the aim direction, to see if there's something blocking the way when the character is preparing to shoot. If there's something in the middle, the character should be calculating the distance between the two to determine if it's still safe to shoot.
