onEvent

public <K> void onEvent(EventType event,

Description copied from interface: EventListener

onEvent is called by EventEmitter via EventEmitter.broadcast(EventType, EventPayload). Allowing the emitter to call any other object that implements this.

Specified by:

onEvent in interface EventListener

Type Parameters:

K - The type of the emitter of this event

Parameters:

event - The type of event

properties - The given event payload

getAxisPlane

public AxisPlane getAxisPlane()

init

private void init()

initialises all the drawing shenanigans we need to do being:

• The origin point
• The grid lines
• Temporary consumers

regInGrid

private void regInGrid(CartesianPoint p,
 CartesianPoint s)

Register a grid line to draw on the grid

Parameters:

p - Point A

s - Point B

grid

private void grid()

Draws the grid with all scaling applied.

existing

public void existing(Supplier<Point> p)

If the given point's coordinates dont already exist within objects, add it.

Parameters:

p - The point supplier (why the fuck is this a supplier)

delete

public void delete(CartesianPoint cartesianPoint)

Delete a point at the given coordinates.

Parameters:

cartesianPoint - The position of the point to delete at.

delete

public void delete(Line l)

Delete any point or line which intersects with the given line

Parameters:

l - The query line. usually drawn by the user.

drawMouse

public static void drawMouse(Graphics2D g,
 CartesianPoint mousePos,
 AxisPlane plane)

Draws the mouse in the world on the actual 3D plane

Parameters:

g - Graphics bro.

mousePos - The position of the mouse in cartesian terms according to the plane

plane - The plane in question

drawDirArr

public static void drawDirArr(Graphics2D g,
 CartesianPoint pos,
 AxisPlane plane,
 boolean xDir)

fromMut

public static Offset fromMut()
