Archers outrange buildings despite having less attack range

[elexis]

Problem: Although archers and CCs / fortresses both have 72m attack range, archers outrange the buildings.

Reason: Currently buildings shoot arrows from the center of the structure while archers can shoot at the edge of a structure and thus outrange it.

Why it should be fixed: This means that archers can park in front of a CC and kill it while not being fired at. Even if you use a british forteress that has 80m range and have a hill advantage, archers can outrange that building, which is pretty lame. This is not only a problem in age 1 as athen and mauryans have devastating champion archers. Especially if your city is close to the enemy this can become a pain as the archer-abusing player can hide between the own towers and become almost invincible and only beatable with far superior economy or using other balancing bugs.

Also, as 72m attack range is defined for structures and archers alike, it seems it is intended for them to be able to attack each other.

Quick fix: Just increase the attack range of buildings in the templates by the radius of the structure.

Extended fix: Automatically add the radius of the building when computing the attack range.

Technically the second proposal is also more historically accurate as archers shoot arrows from the embrasure / arrowslits in the walls of fortresses, not from the center.
