v-2d-transform

A 2D transform library written in the V programming language .

Overview

This library provides various utilities for manipulating 2D vectors and positions, which can be used for game development, simulations, or any application that requires handling of 2D transformations. It includes functions for normalizing vectors, calculating the magnitude of vectors, calculating the distance between vectors, and moving positions based on vectors.

Usage

First, install package from vpm :

v install ArtemkaKun.trnsfrm2d

Then, import the module into your V code:

import artemkakun.trnsfrm2d

Features

Vector

Normalizing a Vector

import artemkakun.trnsfrm2d

v := trnsfrm2d.Vector{1.0, 1.0}
normalized_vector := trnsfrm2d.normalize_vector(v) // returns Vector{0.707106782, 0.707106782}

Calculating distance between Vectors

import artemkakun.trnsfrm2d

v1 := trnsfrm2d.Vector{1.0, 1.0}
v2 := trnsfrm2d.Vector{2.0, 2.0}
distance := trnsfrm2d.calculate_distance_between_vectors(v1, v2) // returns 1.414213562

Position

Calculating a move Vector

import artemkakun.trnsfrm2d

direction := trnsfrm2d.Vector{0, 1}
speed := 2.0
delta_time := 1.0
move_vec := trnsfrm2d.calculate_move_vector(direction, speed, delta_time)! // returns Vector{x: 0, y: 2}

Moving a Position

import artemkakun.trnsfrm2d

pos := trnsfrm2d.Position{
    x: 0
    y: 0
}

move_vec := trnsfrm2d.Vector{
    x: 1
    y: 0
}

new_pos := trnsfrm2d.move_position(pos, move_vec) // returns Position{ x: 1, y: 0 }

Calculating distance between Vectors

import artemkakun.trnsfrm2d

p1 := trnsfrm2d.Position{
    x: 1.0
    y: 1.0
}

p2 := trnsfrm2d.Position{
    x: 2.0
    y: 2.0
}

distance := trnsfrm2d.calculate_distance_between_positions(p1, p2) // returns 1.414213562
