Static Public Methods

public static copy(matrix: Matrix3): * source

Makes a copy of the matrix3. This is a static function and can be called from Matrix3 prototype.

Override:

Matrix#copy

Params:

Name	Type	Attribute	Description
matrix	Matrix3		The matrix3 to copy.

Return:

public static projection(w: number, h: number): * source

Static function which returns a projection matrix converting the top left coordinates to 0, 0, and bottom right to w, h.

(Converted from -1, -1 top left to 1, 1 bottom right.)

Params:

Name	Type	Attribute	Description
w	number		Width of the projection.
h	number		Height of the projection.

Return:

Public Methods

public add(m3: Matrix3) source

Adds a matrix to this matrix.

Override:

Matrix#add

Params:

Name	Type	Attribute	Description
m3	Matrix3		The matrix to add to this matrix.

public multiply(m3: Matrix3): * source

Multiplies a matrix into this matrix.

Override:

Matrix#multiply

Params:

Name	Type	Attribute	Description
m3	Matrix3		The matrix to multiply to this matrix.

Return:

public setPosition(x: number, y: number) source

Sets the translation positions of the matrix with x, y points. This overwrites the values and does not adjust the parameters to work relative to the rest of the matrix values.

Override:

Matrix#setPosition

Params:

Name	Type	Attribute	Description
x	number		X position.
y	number		Y position.

public setRotation(rotationDegree: number) source

Sets the matrix rotation values to rotate an object around the z axis. This overwrites the values and does not adjust the parameters to work relative to the rest of the matrix values.

Override:

Matrix#setRotation

Params:

Name	Type	Attribute	Description
rotationDegree	number

public setScale(x: number, y: number) source

Sets the scale values of the matrix with w, h values. This overwrites the values and does not adjust the parameters to work relative to the rest of the matrix values.

Override:

Matrix#setScale

Params:

Name	Type	Attribute	Description
x	number		X scale.
y	number		Y scale.
