Examples of org.gbcpainter.game.model.grid.Junction

org.gbcpainter.game.model.grid.Junction
Defines a junction between 2 or more {@link org.gbcpainter.game.model.grid.Pipe}
It exposes methods that are used to color, verify the actual coloring state, get the position and apply coloring animations @author Lorenzo Pellegrini
