Trapped Chest

Trapped Chests are blocks which emit a redstone signal from all sides when opened, at a strength of one block per player using it up to 15 players. The Trapped Chest can be told apart from a regular chest by a slight orange tint around the latch and a red line on the rim of the opened chest. Trapped Chests can be made into double Trapped Chests, and are able to be placed adjacent to normal chests without interfering, allowing two chests, or double chests, to be placed adjacent to each other. If the trapped chest is destroyed while it is opened by at least one player, the game crashes.

Trivia

 * Trapped Chest's item in hand is like a normal chest.
 * If a dropper block is placed behind a trapped chest, opening the chest will cause the dropper to put an item in.
