The Wood Wall is a basic wooden building block with a smooth wooden structure with very fine parallel lines.
Like all other building blocks, blocks of Wood Wall too can be rotated into all directions by holding R (as the default key) and moving the left mouse button.
Wood Walls can sometimes be obtained from Silver Keepas or Golden Keepas, and can occasionally also be discovered in randomly spawning Stone Treasure Chests on the Fossil layer underground or on recesses near rivers.
Wood Walls can also very easily be crafted in your Crafting Menu (to be opened by the default key "q"), since the crafting recipe for these basic wooden blocks has become a starting recipe with update R34 (September 2016).
To craft 8 (blocks of) Wood Walls at once, you'll need
- 2 blocks of any kind of Wood (except corrupted wood) from any tree or alternatively 2 Logs (that lie the ground in many surface Biomes)
Attention: Wood Walls are flammable! When placing Wood Walls into hot environments close to (or especially directly above) torches or fiery blocks (like Hardened Lava), Wood Walls can start to burn. Liquid Lava or Fire Bombs will immediately set them on fire.
If Wood Walls start burning, also other flammable blocks nearby can catch fire, and this way a whole wooden house or forest (especially Wildwood, Parchwood and Shorewood) can burn down in hot biomes like Jungles, Savannahs, Shores or on the Lava layer.
Fire cannot be "extinguished" currently, just be stopped from spreading by creating forest aisles/swaths wide enough so the flames cannot leap over, or (since R33) by claiming the area and disabling the fire spreading option for the claim.
On worlds of players who bought the "Pro" DLC, the fire spreading (fire sim) option can be disabled for the whole gameworld. On player claims, fire spreading is disabled by default since update R33 2/3, but can be enabled by claim owners.
