Echo Block

The Echo Block is a block which turns completely invisible once placed. It is sold by the Cyborg NPC for when he is spoken to in a Graveyard.

Once placed, the Echo Block cannot be seen by the player unless they have the Spectre Goggles equipped (purchasable for under the same conditions).

Echo Blocks work similarly to most blocks as they can be hammered, actuated with an Actuator, and can be stood on or used to hoik.

Usage
Echo Blocks can be used for various building-related tasks such as:


 * Attempting to make furniture, liquids or other objects appear as if they are floating.
 * Hiding secret messages or symbols that are only visible with Spectre Goggles equipped.
 * Building valid NPC housing with invisible walls.
 * Creating invisible hook paths.
