Usage

| Mouse button | Action |
|---|---|
| Button 4 | Open Resource Scanner settings screen |
| Button 5 | Scan nearby resources |
Pressing the scanner button will reveal the resouces, if any, in player's vicinity. It starts easy, with coal and deepslate coal ores, but later can be set up to look for anything you want (as long as you want to locate an ore). Just press mouse button 5 and enjoy.
The configuration is done through config/resource-scanner.json file. It will be created after first run. Alternatively, if you have a Mod Menu plugin installed, you can go into its screen from Minecraft menu and change the options there. Since version 0.5.2, you can also use mouse button 4 to get to the settings, even without Mod Menu plugin.
You can tweak the distance the scanner will try to reach, as well as width of the scaner cone and who long echoes are kept on screen. Finally, you can select the kinds of ore the scanner should look for.

Running a scan will unveil chosen resources in player's vicinity. For instance, looking for iron might look something like this:


At the same time, putting a wider net may reveal much more iron, coal, dimonds and maybe some gold or redstone.

Settings GUI
While it is possible to modify the scanner reach in the main menu you can, a runnig session is needed to to also select kinds of ore to scan.


This inventory can contain up to 18 ore kinds. It is possible to add more directly through the JSON file, but as shown on the screenshot, there no much more ores to choose from.
