Vector2

Fields

---

Name	Type	Ranges
x	float	X coordinates
y	float	Y coordinates

Functions

---

Vector2()

Return value

Name	Type	Description
vector	Vector2	Returns a Vector2 ( 0, 0 )

Example

local pos = Vector2()
EngineClient:ExecuteCmd("echo x: " .. tostring(pos:x))
EngineClient:ExecuteCmd("echo y: " .. tostring(pos:y))

This code will create a Vector2 instance and then print out all the fields. This will create an invalid vector.

---

Vector2()

Parameters

Parameter	Type	Description
x	float	X coordinates
y	float	Y coordinates

Return value

Name	Type	Description
vector	Vector2	Returns a Vector2 ( x, y )

Example

local pos = Vector2(85,0)
EngineClient:ExecuteCmd("echo x: " .. tostring(pos:x))
EngineClient:ExecuteCmd("echo y: " .. tostring(pos:y))

This code will create a Vector2 instance and then print out all the fields.

---

IsValid()

Return value

Name	Type	Description
valid	bool	Returns true if the vector is valid, it's components aren't infinite values

Example

local pos = Vector2()
if pos:IsValid() then
  EngineClient:ExecuteCmd("echo the vector is valid")
end

The body of the if statement will never be executed because the vector is invalid.

---

DistanceTo()

Parameters

Parameter	Type	Description
vector	Vector2	The other vector

Return value

Name	Type	Description
distance	float	Returns the distance to the second vector

Example

local pos1 = Vector2(85,640)
local pos2 = Vector2(240, 940)
EngineClient:ExecuteCmd("echo distance: " .. tostring(pos1:DistanceTo(pos2)))

This will print the distance between the two vectors.

---

Lenght()

Return value

Name	Type	Description
lenght	float	Returns the lenght of the vector

Example

local pos = Vector2(85,640)
EngineClient:ExecuteCmd("echo lenght: " .. tostring(pos:Lenght())

This code will print the lenght of the vector.

---

DotProduct()

Parameters

Parameter	Type	Description
vector	Vector2	The other vector

Return value

Name	Type	Description
lenght	float	Returns the dot product

Example

local pos1 = Vector2(85,640)
local pos2 = Vector2(120, 250)
EngineClient:ExecuteCmd("echo dot: " .. tostring(pos1:DotProduct(pos2))

This code will print the dot product of the vectors.

---

CrossProduct()

Parameters

Parameter	Type	Description
vector	Vector2	The other vector

Return value

Name	Type	Description
vector	Vector2	Returns the cross product

Example

local pos1 = Vector2(85,640)
local pos2 = Vector2(120, 250)
local cross = pos1:CrossProduct(pos2)
EngineClient:ExecuteCmd("echo cross x: " .. tostring(cross:x)
EngineClient:ExecuteCmd("echo cross y: " .. tostring(cross:y)

This code will print the cross product of the vectors.
