Make enemies attack surface of building, not center

Question

In my game, a player must defend a building from attacking enemies. The ground enemies spawn at random places around the building, and they all walk towards the building to start attacking it with their axes:

agent.SetDestination(target.position);

target.position is the position of the building object.

It makes sense of course that the enemies try to reach the center of the building, but they should attack the surface. I tried adding

if (distance <= attackDistance)

to make sure the enemies respect a minimum distance, but since the building is not a sphere this doesn't work very good.

What's the proper way to do this?

You could raycast against the building's collider and when the distance between the Unit and the RaycastHit.point is below the attackDistance, then attack. — Draco18s no longer trusts SE

You can put empty gameObjects around the building as little "attack points"

But a more proper way to do this is to make it so when enemies detect a collision with the walls, they go into an attacking state.

Other than that, I'm not exactly sure what you mean. Are they attacking a compound around the building? Are they just bashing an axe on the walls of a building?

I could help you further if you gave more information.
