constructor Function:Public Vector2 (float x, float y);
Description: The value that is required to pass in the vector, or the default constructor, because the object is a value type because it is a struct

Public variables:Public Vector2 normalized {get;}
Description: Returns the unit vector of a vector, returning a new vector without changing the vector value. If the vector is too small, it may return a 0 vector.

Public float magnitude {get;}
Description: Returns the length of the vector, if only the comparison vector size should be used Sqrmagnitude

Public float sqrmagnitude {get;}
Description: Calculates the square of the vector length quickly, so the comparison vector size uses this property

Public float This[int index] {get; set;}
Description: Use the indexer to access the value of x = [0],y = [1]

public float y;
public float x;
Description: The two coordinate values of the vector

Public function:public void Normalize ();
Description: The current vector will be normalized, changing the current vector's value, and substituting the attribute if you do not want to change it. If it's too small, return 0 vectors.

public void Set (float new_x, float new_y);
Description: Sets the X, y value of the vector that already exists

public void scale (Vector2 scale);
Description: Enlarges this vector by scale

public override string ToString ();
public string ToString (string format);
Description: Returns the string format of a vector

static function:public static float Angle (Vector2 from, Vector2 to);
Description: Gets the angle between two vectors [0, 180], without order

public static Vector2 clampmagnitude (Vector2 vector, float maxLength);
Description: Returns a vector of the same unit vector as the vector, with a size of maxLength

public static float Distance (Vector2 A, Vector2 b);
Description: Returns the distance of the A vector from the B vector. (A-B) magnitude

public static float Dot (Vector2 lhs, Vector2 RHS);
Description: Return LHS * RHS

public static Vector2 Lerp (Vector2 A, Vector2 B, float t);
public static Vector2 lerpunclamped (Vector2 A, Vector2 B, float t);
Description: A vector is inserted in Linear a B, and T [0,1] denotes [a, b]

public static Vector2 Max (Vector2 lhs, Vector2 RHS);
public static Vector2 Min (Vector2 lhs, Vector2 RHS);
Description: A new vector consisting of the maximum (minimum) values in two vectors

public static Vector2 Movetowards (Vector2, Vector2 target, float maxdistancedelta);
Note: Move the current in the direction vector with target, no more than target Maxdistancedelta

public static Vector2 Reflect (Vector2 indirection, Vector2 innormal);
Description: Map the indirection to the Innormal

public static Vector2 scale (Vector2 A, Vector2 b);
Description: Gets a vector of the product of the elements of a B vector

public static Vector2 Smoothdamp (Vector2 current, Vector2 target, ref Vector2 currentvelocity, float smoothtime);
public static Vector2 Smoothdamp (Vector2 current, Vector2 target, ref Vector2 currentvelocity, float smoothtime, float max Speed);
public static Vector2 Smoothdamp (Vector2 current, Vector2 target, ref Vector2 currentvelocity, float smoothtime, float max Speed, float deltatime);
Note: Gradually move a vector to the target location
Current: coordinates
Target: Destination coordinates
Currentvelocity: The speed at which each call to this function gets
Smoothtime: About the time spent, the smaller the value, the greater the speed
Maxspeed: Limit the maximum speed
Deltatime: Invokes the event interval, which defaults to Time.deltatime.

operator Overloading: all operator overloads are in a static function, and all operations do not affect the original vectorpublic static Vector2 operator-(Vector2 a);
Description: Reverse the vector

public static Vector2 operator-(Vector2 A, Vector2 b);
Description: Vector A-B

public static Vector2 operator * (float D, Vector2 a);
public static Vector2 operator * (Vector2 A, float d);
Description: The vector is multiplied by the real number

public static Vector2 operator/(Vector2 A, float d);
Description: Divide the vector by the real number

public static Vector2 operator + (Vector2 A, Vector2 b);
Description: vector addition

public static BOOL operator = = (Vector2 lhs, Vector2 RHS);
public static bool Operator! = (Vector2 lhs, Vector2 RHS);
Description: Determine if vectors are equal

public static implicit operator Vector3 (Vector2 v);
public static implicit operator Vector2 (Vector3 v);
Description: Implicit conversion conversions between 2D and 3D vectors
