The level or damage of the attacker, the level of the wall, and the total distance to the target all affects the decision to go through or around a wall.

To prevent walls from being attacked, increase the thickness of the wall the farther it is from an entrance. The inner squares will often have additional walls, flowers, or be empty.

To prevent ranged attackers from shooting over walls, have at least 3 squares between the outer wall and any inner building. The castle wall has an opening, but the opening is heavily protected. These bases all have openings in the walls, so the defender chooses where the attacker enters. Flying units ignore walls and cannot be influenced. The second basic principle of base design is using walls against ground attackers to make 'travel until the target is in range' involve walking farther distances and through more damage. Towers are designed for this, and arrow towers have the highest HP. Surround heroes by other buildings that will be targeted. The first basic principle of base design is ensuring that 'choose the nearest target' is not a hero. Attackers targeting a regular building, not a tower, will pause to counter attack then return to the same building. For destructive troops, the nearest target is the nearest tower if there is one. Choose the nearest target, travel until it is in range, attack until it is destroyed. The rules of attacking troops and heroes are fairly simple.
