Tool

A tool is an item that a blockhead can use to interact with its environment. For example, a pickaxe can be used to mine stone.

Using
For a blockhead to use a tool, it must first be in an accessible slot in that blockhead's inventory. It must then be selected, which allows it to be used. While selected, the blockhead is directed to act on a location, block, or creature. If the resulting outline shows an icon of the selected tool, that tool will be in use.

Tools have appropriate and inappropriate uses, denoted by the color of the outline that appears. White outlines are neutral, and mean the tool has the same effect as an empty hand. A red outline means the tool is inappropriate and will be no more effective than an empty hand, implying it will take more wear than necessary as well. A green outline means the tool is appropriate and will be more effective than an empty hand.

Most tools are appropriate for attacking creatures. Weapons are tools that are only appropriate for attacking creatures. They also are more effective than other tools at that task.

A blockhead's hand is a special case. It can serve as a tool or weapon, and is the default tool for certain types of harvesting such as picking fruit off trees or picking up loose items.
