Method Details

contains

public boolean contains(Vector2f point)

intersects

public boolean intersects(Rectangle with)

intersectsLazy

public boolean intersectsLazy(Rectangle with)

getVertices

public Vector2f[] getVertices()

Translates bounds to vertices.

Overrides:

getVertices in class Polygon

Returns:

vertices of rectangle

getAxes

public Vector2f[] getAxes()

Gets the normalized axes of every edge of the Polygon. This is used in for collision detection. Because this is a Rectangle object, only 2 axes are required to check.

Overrides:

getAxes in class Polygon

Returns:

axes of all edges.

getCenter

public Vector2f getCenter()

Overrides:

getCenter in class Shape

getHeight

public float getHeight()

setHeight

public void setHeight(float height)

getX
