Touchplates are a mechanical item in Deepworld that can be used to interact with certain other items, and can be triggered by both characters, butler bots, and NPCs.
How to use
To link up a touchplate to another object (i.e. mechanical door), you must first place the touchplate, followed by the other item. Placing the items in the reverse order will not do anything. After placing the touchplate, a GUI will pop up, allowing you to enter text for the plate to read upon activation as well as the ability to set a color to the touchplate. The touchplate works just like a normal switch in that it has two activation states, and the state is changed whenever a player or NPC touches the plate.
