Attention this plugin is a pure free time project and was originally written for me and my friends. So please do not expect regular updates or an ultra high performace!
Features:
In summary, the features are:
by left/right-clicking on the PorticleGun item, you can create the portals
if you left/right-click on the PorticleGun Item + while sneaking, an inventory opens, where you can set the color of the portals and delete the portals already set.
If you drop the item from your hand with the drop key the gravity gun is activated. With this, you can transport blocks (including spawners) or entities from A to B. (To actually drop the item, double click your drop key).
