Rubblemaker

The Rubblemaker is a tool used to place ambient objects rubble using items from the player's inventory. It is sold by the Goblin Tinkerer in Hardmode for.

By pressing the button, the Rubblemaker can toggle between three placement sizes: Small, Medium, and Large. The Small setting corresponds to one tile-wide rubble, the Medium setting to two tile-wide rubble, and the Large setting to three tile-wide rubble. Rubble within each setting can be cycled through using the and  buttons. The material which is highest and furthest to the left in the player's inventory will be prioritized, and only that material's rubble will be placeable until another supersedes it.

Placeable rubble
Rubble objects are listed in the order in which the game cycles through them. Pressing the button advances the cycle forward.

Unimplemented
An unused array of textures for the Tile ID 653 and a list of accompanying items the Rubblemaker would consume to place them can be found in the game's files. The name of the method in which the latter is stored, ForModders_AddPotsToWand, indicates that the unused rubble recipes were left behind for modders. All of the textures are identical to the various types of pots which naturally generate in worlds; nearly every pot would be placed by an item found in the biome in which it generates.
