sub

public IntVector3 sub(int x,
                      int y,
                      int z)

multiply

public IntVector3 multiply(int factor)

plus

public IntVector3 plus(IntVector3 other)

Returns the result of the addition of this vector and the other vector. This returns a new vector, and leaves this vector unchanged.

Parameters:

other -

Returns:

minus

public IntVector3 minus(IntVector3 other)

Returns the result of the subtraction of the other vector from this vector. This returns a new vector, and leaves this vector unchanged.

Parameters:

other -

Returns:

times

public IntVector3 times(int factor)

negate

public IntVector3 negate()

length

public int length()

lengthXZ

public int lengthXZ()

dotProduct

public int dotProduct(IntVector3 v)

scale

public IntVector3 scale(int s)

getRotationTo

public Quaternion getRotationTo(IntVector3 destination)

Gets the shortest arc quaternion to rotate this vector to the destination vector. Don't call this if you think the dest vector can be close to the inverse of this vector, since then ANY axis of rotation is ok.
