xVector2

[INFORMATION]

This is a Vector2 Class asset libary with a good amount of functionality to get you covered for most tasks (GMS 2.3+)

[QUICK GUIDE]

1) This module implements a constructor class so you just need to do:

var _vector = new Vector2(10, 10); // Creates a x: 10, y: 10 vector
var _newVector = _vector.multiplyBy(2); // Multiplies "vector" by 2
    
// NOTE: methods don't mutate the current instance.
// Meaning a new vector is created everytime, keeping the original vector unchanged.

2) However you may want to change the original vector. For your convenience I've included a Vector2Utils class:

var _vector = new Vector2(3, 7);
Vector2Utils.normalize(_vector); // mutates the original vector.
   
// NOTE: This allows every-step computations to keep a lighter impact on the GC. 

[MANUAL]

This library provides a set of useful function that you can use to create and manipulate Vector2:

var _vector = new Vector2(10, 10);
// returns the length of the vector
_vector.length()
     
// returns the squared length of the vector
_vector.legnthSquared() 
  
// returns a new vector with the given magnitude.
_vector.withMagnitude(magnitude)
   
// return a new normalized vector.
_vector.normalize()
   
// returns a new reflected vector according to a normal vector.
_vector.reflect(normal)
    
// returns a new vector with clamped x/y components.
_vector.limit(min, max) 
    
// return a new vector "lerped" towards the dest by a given amount.
_vector.interpolate(dest, amount)
    
// returns a new vector with the sum result.
_vector.add(vector);
   
// returns a new vector with the subtraction result.
_vector.subtract(vector)
   
// returns a new vector with the multiplication result.
_vector.multiply(vector) 
    
// returns a new vector multiplied by a single value.
_vector.multiplyBy(amount)
     
// returns a new vector with the division result.
_vector.divide(vector)
    
// returns a new vector divided by a single value.
_vector.divideBy(amount) 
    
// returns a new negated vector (-x, -y).
_vector.negate();
    
// equality check between two vector2 instances.
_vector.equals(vector)
    
// stores the vector elements in a given array starting at the given index.
_vector.copyToArray(array, index)

Regarding the mutable functions inside the Vector2Utils namespace the functionality is very much the same. Please check the fully documented source code.

[COMPATIBILITY]

The asset is fully compatible with GMS2.3+ and is purely written in GML making it compatible with all exports available.
