# Vec2

### Properties

* <mark style="color:purple;">`x`</mark> - double
* <mark style="color:purple;">`y`</mark> - double

### Methods

* [constructor](#vec2-new-x-y)
* [length](#length)
* [distanceTo](#distanceto-othervec2)
* [angleTo](#angleto-othervec2)
* [normalized](#normalized)
* [scale](#scale-scalar)

### <mark style="color:green;">`Vec2:new(x, y)`</mark>

* <mark style="color:purple;">`x`</mark> - What to set x to
* <mark style="color:purple;">`y`</mark> - What to set y to&#x20;

Constructs a new Vec2 with the provided x and y.

**Example:**

```lua
local screenPosition = Vec2:new(200, 200)
```

### <mark style="color:green;">`length()`</mark>

Returns the length of the Vec2&#x20;

**Example:**

```lua
local vec = Vec2:new(200, 200)
print("The vector has a length of " .. vecL:length())
```

### <mark style="color:green;">`distanceTo(otherVec2)`</mark>

* <mark style="color:purple;">`otherVec2`</mark> - A different Vec2&#x20;

Returns the distance from this vector to the `otherVec2`

**Example:**

```lua
local vecA = Vec2:new(200, 200)
local vecB = Vec2:new(400, 690)
print("Distance from vecA to vecB: " .. vecA:distanceTo(vecB))
```

### <mark style="color:green;">`angleTo(otherVec2)`</mark>

* <mark style="color:purple;">`otherVec2`</mark> - A different Vec2&#x20;

Returns the angle to the `otherVec2`

**Example:**

```lua
local vecA = Vec2:new(1, 0)
local vecB = Vec2:new(0, 1)
print("Angle between vecA and vecB: " .. vecA:angleTo(vecB)) --prints 90
```

### <mark style="color:green;">`normalized()`</mark>

Returns this vector but normalized (that is with length 1)

**Example:**

```lua
local vecA = Vec2:new(20, 10)
print("vecA normalized: " .. vecA:normalized():toString()) --prints (0.8944, 0.4472)
```

### <mark style="color:green;">`scale(scalar)`</mark>

* <mark style="color:purple;">`scalar`</mark> - By how much you want to scale the vector

Returns a scaled version of this vector

**Example:**

```lua
local vecA = Vec2:new(20, 10)
print("vecA scaled by 2: " .. vecA:scale(2):toString()) --prints (40, 20)
```

### <mark style="color:green;">`toString()`</mark>

Returns a string representation of the Vec2

**Example:**

```lua
local vecA = Vec2:new(20, 10)
print("vecA: " .. vecA:toString()) --prints (20, 10)
```
