Good day,
Building castles is great, but some more military-themed decorations could be available, to add to the atmosphere of a military location. Some could even have cool functions.
Wooden palisades- These would essentially have the same texture as logs, but applied to a block that is a stripped-down log with the top end sharpened to a point. They could link together like fences, and if an entity comes in contact with the pointed top, it would cause some damage. A similar concept is featured in the Witchery Mod. Crafting these could be as simple as putting a few logs in a spike shape.
"Lilies" or small pit traps- These fortifications were used extensively by the Romans, Carthaginians, and other ancient factions, so it would certainly be fitting for the time period. What these would be is a block whose top surface is textured like grass, but this hides a small wooden stake underneath to injure attackers who tread on it. Crafting for this item could involve using a palisade and some grass or leaf blocks.
Arrow/Bolt barrels- These would be simple to implement, as they could use the pre-existing barrel model and texture for a base. The difference would be that the top is removed, and bunches of arrows would be stuffed point-downwards in the barrel. Not only would these be a cool decorative item for watchtowers and the like, but you could also use it to store arrows and crossbow bolts, and clicking on it would give you a certain amound of projectiles. A crafting recipe could simply be a barrel with some bits of iron and an arrow.
Brazier- As enchantments are difficult to obtain in Middle-Earth, this could be an alternative method of igniting your arrows during a siege. The asthetic of these could be as simple as something like a beacon of gondor encased by black iron bars. Crafting would involve iron ingots, logs, and sticks.
Watchman's lantern- This item could function as a torch in that it can be placed on a wall for lighting, but if held in a selected hotbar slot, it could provide lighting in a small radius around the player. Crafting would require a bit of iron and a torch.
Weapon Racks being able to hold bows- Exactly what it says on the tin.
Rope ladders- Perfect for discreetly descending a castle wall, or use as a retractable means of entry to a small watchtower. Crafted out of string and sticks, this would function like a gate in that clicking the topmost block of the ladder would extend/retract it a certain number of blocks.
Tall Torches- Just like the Orc Torch and the Tauredain torch, these torches would be two blocks tall. Except now these could be available to other factions; they would be useful to line battlments and towers. Crafted by simply adding one more stick to the torch recipe.
I look forward to hearing opinions on these ideas; thanks for your time.
