The texture of the chest is different if you look closely where the latch goes. Trapped chests are like redstone signals. If you open it, the chest will send a redstone signal like a pressure plate. You can see some redstone at the part where you connect the latch.
Works just like the regular chest. This design was made for a new animation coming soon!
