Method Details

processClockwiseRotation

@NotNull
@Contract(pure=true)
public static Map.Entry<Integer,Integer> processClockwiseRotation(int x,
 int y,
 int length,
 int height,
 int rotation)

Calculates a clockwise rotation across a two dimensional grid

Parameters:

x - the standard x coordinate

y - the standard y coordinate

length - the length of the grid

height - the height of the grid

rotation - the rotation in degrees

Returns:

a pair of new coordinates, with the x coordinate being the key and the y coordinate being the value

processCounterClockwiseRotation

@NotNull
@Contract(pure=true)
public static Map.Entry<Integer,Integer> processCounterClockwiseRotation(int x,
 int y,
 int length,
 int height,
 int rotation)

Calculates a counter clockwise rotation across a two dimensional grid. This is the same as calling processClockwiseRotation(int, int, int, int, int) with 360 - rotation as the rotation.

Parameters:

x - the standard x coordinate

y - the standard y coordinate

length - the length of the grid

height - the height of the grid

rotation - the rotation in degrees

Returns:

a pair of new coordinates, with the x coordinate being the key and the y coordinate being the value

xyToSlot

@Contract(pure=true)
public static int xyToSlot(int x,
 int y)

slotToXY

@Contract(pure=true)
public static int[] slotToXY(int slot)

getBorders

@Contract(pure=true)
public static int[] getBorders(int row)
