Constructor & Destructor Documentation

IntRect()

IntRect	(	int	xmin,
		int	ymin,
		int	xmax,
		int	ymax
	)

Member Function Documentation

Contains()

bool Contains	(	int	x,
		int	y
	)

DebugDraw()

void DebugDraw	(	GraphTransform	transform,
		Color	color
	)

Draws some debug lines representing the rect in the XZ plane.

Equals()

override bool Equals

(

System.Object

obj

)

Expand()

IntRect Expand

(

int

range

)

Returns a new rect which is expanded by range in all directions.

Parameters

range

How far to expand. Negative values are permitted.

ExpandToContain()

IntRect ExpandToContain	(	int	x,
		int	y
	)

Returns a new IntRect which is expanded to contain the point.

GetHashCode()

override int GetHashCode

(

)

Intersection()

static IntRect Intersection ( IntRect  a, IntRect  b  )

static

Returns the intersection rect between the two rects.

The intersection rect is the area which is inside both rects. If the rects do not have an intersection, an invalid rect is returned.

IsValid

Intersects()

static bool Intersects ( IntRect  a, IntRect  b  )

static

Returns if the two rectangles intersect each other.

IsValid()

bool IsValid

(

)

Returns if this rectangle is valid.

An invalid rect could have e.g xmin > xmax. Rectangles with a zero area are invalid.

Offset() [1/2]

IntRect Offset

(

Int2

offset

)

Returns a new rect which is offset by the specified amount.

Offset() [2/2]

IntRect Offset	(	int	x,
		int	y
	)

Returns a new rect which is offset by the specified amount.

operator!=()

static bool operator!= ( IntRect  a, IntRect  b  )

static

operator==()

static bool operator== ( IntRect  a, IntRect  b  )

static

Rotate()

IntRect Rotate

(

int

r

)

Returns a new rect rotated around the origin 90*r degrees.

Ensures that a valid rect is returned.

ToString()

override string ToString

(

)

Union()

static IntRect Union ( IntRect  a, IntRect  b  )

static

Returns a new rect which contains both input rects.

This rectangle may contain areas outside both input rects as well in some cases.

Member Data Documentation

Rotations

readonly int [] Rotations

staticprivate

Initial value:

= {
            1, 0,  
            0, 1,

            0, 1,
            -1, 0,

            -1, 0,
            0, -1,

            0, -1,
            1, 0
        }

Matrices for rotation.

Each group of 4 elements is a 2x2 matrix. The XZ position is multiplied by this. So

//A rotation by 90 degrees clockwise, second matrix in the array
(5,2) * ((0, 1), (-1, 0)) = (2,-5)

xmax

int xmax

xmin

int xmin

ymax

int ymax

ymin

int ymin
