Guide:Renewability

All Resources are Infinite
Resources only differ in their scarcity. Even though in a created world the amounts of certain items appears to be finite, i.e. number of gold ore tiles, while other resources grow back, spawn randomly or can be otherwise replenished, generally all items can be transferred between worlds and between characters and thus there is no theoretical incentive for saving up, rationing or hoarding items or materials. Rather a player can choose to gather and produce materials in bulk, or collect and craft items as required, while discarding anything that is of no immediate use. At any time a new world can be created and all its treasures and minerals gathered, the character's Inventory, Safe and Piggy Bank are shared between different worlds.

Wood
Wood is arguably the most common and renewable resource. Chopping down Forest and Hallow Trees frequently drops Acorns that can be planted to grow new trees. Or it can be found growing up by itself on jungle blocks (creating an artificial jungle is a good way to harvest wood without using acorn, jungle tree also won't produce acorns.)

Wood is one of the most versatile resources as well, as it is used in both construction and crafting:


 * Wood can be used for both building structures and background walls.
 * Wood is used for creating Torches and Wood Platforms.

Sand
Sand is an infinite resource if you have patience or the equipment:


 * Antlions can be goaded into generating more sand, albeit very slowly.
 * A Sandgun used with ammunition-conserving equipment, such as the Necro Armor set, can produce infinite sand.

Cactus
Cactus is an infinite resource as long as there is 1 layer of sand, since it spawns automatically. Cactus can be harvested with ease by just removing the 1 sand block below it and sold for money or crafted to potions.

Glass
Glass is indirectly renewable because it is crafted from Sand, which can be produced infinitely.

All plants are renewable resources because they can be replenished by seeds, or grow naturally in their respective Biome.
