About this project

What does BlockDetector add?

This mod adds a block very similar to the observer that only monitors block changes. This means that while the observer outputs a pulse every time a block changes state (like the "age" of a fire or the growth of plants), the block detector can be configured to only output a signal when the actual block changes (placing or breaking a block) or when the state changes.

There are three options for the output type:

  • Normal: The block outputs a redstone signal when the block or state in front is equal to the filter
  • Inverted: The block outputs a redstone signal when the block or state in front is anything but the filter
  • Pulse: The block outputs a redstone pulse whenever the block or state in front changes

The output type and the filter can be changed in the GUI. The filter can be set to any block including fire. To use fire as the filter, place a flint and steel into the slot.

Known issues:

  • When the Block Detector is set to be state aware it is not updated by plants growing and fire aging, placing or breaking plants and fire updates as intended
