Additions[]

Blocks[]

Block of Redstone JE1 BE1.png Block of redstone
  • Stores redstone dust similar to blocks of diamond, etc.
  • Emits constant redstone power.
  • Works as a pushable redstone power source.
Daylight Detector JE1 BE1.png Daylight sensors
  • Output power while receiving sunlight.
  • The level varies depending on the time (more sunlight=more redstone power), and it does not function at night.
Hopper (D) JE1.png Hoppers
Nether Quartz Ore JE1 BE1.png Nether quartz ore
Redstone Comparator (S) JE1.png Redstone comparator
  • Has 2 inputs and 1 output.
  • If A≥B, the output will be A, otherwise it will stay off – When the comparator is toggled, it will output full strength instead of A it will subtract B from A and need a comparator as input for B.
  • Replacement for the capacitor.
  • Whichever side gives the bigger signal will be considered signal B.
Trapped Chest.gif Trapped chests
  • Gives out a signal depending on the amount of players looking inside. 1 person = 1 strength signal, 2 people = 2, etc.
  • Crafted with a chest and a tripwire hook.
  • Large trapped chests can be staggered with large chests to allow more compact storage.
  • Texture is slightly different than a normal chest, with a red stain around the latch.
Light Weighted Pressure Plate JE1 BE1.png Heavy Weighted Pressure Plate JE1 BE1.png Weighted pressure plates
  • Detects item stacks.
  • Gold version reaches full strength at 60 items.
  • Iron version reaches full strength at 600 items.
  • Linear, so 10 strength signal means twice as many items as a 5 strength signal.
