I wanted to start a new thread on how walls work, but saw too many when i searched and didn't want to get the "use search" bombardment
Here is my idea related to the OP:
3 types of walls
-fence
-wall
-fortified wall
Each wall type can be made from either
-wood
-brick
-stone
Wall sections
-wall
-corner post
-gate
-tower
-gatehouse
The fences would be like round pole fences, but have a stone and brick version, no metal required and only slightly stronger than round pole. They would have no soak or very low soak (say 50-75 str to break with bare hands) Brick and stone versions could be locked. used mostly for decoration and animal pens.
Walls would work like current walls, but would have lower soak values and a new wall would be added, stone walls. Stone walls would be stronger than brick and would require wrought for the gate and mortar for every tile, brick walls would use any hard metal (bronze, iron, steel) for the gate and corner posts. The metal requirements could be lowered (to reflect the lower protection)
Fortified walls would be stronger than current walls and none can be broken by bare hands. These walls would be 3x1 for wall sections and 3x3 for towers and 3x3 for corners, towers would count as corners but more expensive to build. Towers would allow players to get on top of the walls. Standing on top of walls would give a defense bonus when being attacked by ranged weapons and an attack speed bonus when using ranged weapons. When building a tower you have the option to choose direction of the entrance (south or east facing), entrance side can not be extended from. Gatehouse would be a special wall section 3x3 acts like a corner post but can only be extended on the sides the gate isn't on. Gate in gatehouse would be 1 tile (middle).
layout:
x= solid
o=walkable
e entrance
x
0 = fortified wall east/west
x
x o x = fortified wall north/south
x o x
o o o = newly built corner (also corner that is extended from on all 4 sides)
x o x
x x x
o o x = top right corner (corner must be extended from on west and south side and sealed to block it off, other corners are the same idea)
x o x
x o x
x o e = east facing tower
x o x
x x x
o o o = south facing tower
x e x
x o x
e o e - east/west facing gatehouse
x o x
x e x
o o o -north/south facing gatehouse
x e x
Towers follow same idea as corners with which side is blocked from waling when sealed. Sealing fortified corners/towers requires some of the material used to build it, stone+mortar, wood+bone glue or brick+mortar.
Gates could be built with 2-3 spaces between towers, corner posts or gatehouses.
Build menu for fortified walls would be:
Extend north, south, east, west (depending on which direction you are able to build)
Place Cornerpost
Place Tower, south or east
Place Gatehouse, south, north, east, west
Make gate to, north, south, east, west
