Survey Tools
Survey Tools gives you distance measurements between two points using Redstone Torches. Survey Tools does not use any commands, instead, all interaction is done using player actions.
To use: 1. Place a Redstone Torch on the block you would like to measure from. 2. Using a second Redstone Torch, shift-right-click the first Redstone Torch to set your survey marker. 3. Shift-right-click another block to get a Survey Report with the distance to the first block.
Installation: To install, copy the .jar into the plugins directory.
Localization: All display text can be changed in config.yml
