Verctor3 Information And Methods

Question 1

Vector3
Representation of 3D vectors and points.
This structure is used throughout unity to pass 3D positions and directions around. It also contains functions for doing common vector operations.

Answer 1

Other classes can be used to manipulate vectors and points as well. For example Quaternion and Matrix4x4 classes are useful for rotating or transforming vectors and points.

Question 2

Vector3 Static Properties list

Answer 2

Back (0.0-1)
Down(0.-1.0)
Forward(0.0.1)
Left(-1.0.0)
NegativeInfinity( Shorthand for writing Vector3, float.NegavtiveInfinity, float.NegavtiveInfinity, float.NegavtiveInfinity)
One, shorthand for writing Vector3 (1.1.1)
PositiveInfinity, shorthand for writing Vector3 (float.PositiveInfinity, float.PositiveInfinity, float.PositiveInfinity)
Right, shorthand for writing Vector3 (1.0.0)
Up(0.1.0)
Zero(0.0.0)

Question 3

Vector3 is a Constructor that creates a new vector with given x, y, z components

Answer 3

Properties
Magnitude, returns the length of this vector (read only)
Normalized, returns this vector with a magnitude of 1 (read only)
SqrMagnitude, returns the squared length of this vector(read only)
This[int], Access the x, y, z components using[0],[1],[2] respectively
X, x component of the vector
Y, y component of the vector
Z, z component of the vector

Question 4

Operators in unity

Answer 4

• subtracts one vector from another
  ! = Returns true of vectors are different
• Multiplies a vector by a number
  / Divides a vector by a number
  + Adds two vectors
  == Returns true of two vectors are approximately equal.
