Constructor Detail

b2Mat22

public b2Mat22(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

b2Mat22

public b2Mat22(long size)

Native array allocator. Access with Pointer.position(long).

b2Mat22

public b2Mat22()

The default constructor does nothing (for performance).

b2Mat22

public b2Mat22(@Const @ByRef
               b2Vec2 c1,
               @Const @ByRef
               b2Vec2 c2)

Construct this matrix using columns.

b2Mat22

public b2Mat22(@Cast(value="float32")
               float a11,
               @Cast(value="float32")
               float a12,
               @Cast(value="float32")
               float a21,
               @Cast(value="float32")
               float a22)

Construct this matrix using scalars.

Method Detail

position

public b2Mat22 position(long position)

Overrides:

position in class Pointer

getPointer

public b2Mat22 getPointer(long i)

Overrides:

getPointer in class Pointer

Set

public void Set(@Const @ByRef
                b2Vec2 c1,
                @Const @ByRef
                b2Vec2 c2)

Initialize this matrix using columns.

SetIdentity

public void SetIdentity()

Set this to the identity matrix.

SetZero

public void SetZero()

Set this matrix to all zeros.

GetInverse

@ByVal
public b2Mat22 GetInverse()

Solve

@ByVal
public b2Vec2 Solve(@Const @ByRef
                           b2Vec2 b)

Solve A * x = b, where b is a column vector. This is more efficient than computing the inverse in one-shot cases.
