Creeper explosions can be incredibly frustrating. They destroy nice landscapes or even expensive and time consuming builds. This mod provides a solution to that. In fact, it provides multiple solutions.
The mod comes with certain built in commands.
Unfortunately, there is not yet a command to set up or delete protected areas.
To do so, open your minecraft folder and go to /config. Open anti-creeper.properties. Here you see all mod settings. Next to areas= you can add areas to protect.
To add an area, write: <x1>,<z1>,<x2>,<z2>,<type>;
without any spaces. <x1> and <z1> should be replaced with the x and z coordinates of one of the blocks you chose to define the protected area. <x2> and <z2> should be replaced with the x and z coordinates of the other block. <type> should be replaced with either circle or rectangle, depending on the shape you want to protect.
An example would be: areas=0,0,8,8,rectangle;0,0,-8,-8,circle;
Once youre done modifying the file, save it and run /anticreeper load (or restart the game).
