Can we learn something practical from a pure computer science interview question? In this article we will solve an interview question and optimize it – but we will also look at a practical way to handle data in real life.…
Finding a single unique number in a list containing pairs might sound pretty simple, right?
Because a one-sentence description might be misleading, let’s start with an example of an input array:
[1,3,17,3,1]
Given such an array, the unique number is …
How to create a simple and efficient collision detection between paths in your HTML5 Canvas app or game? In this article we will create a maze, allow a player to navigate through the maze and detect when the player collides …
The Array Nesting interview question might seem complex at first and very simple after you solve it. But sometimes, a deeper dive into it can expose some more performance optimizations that can be interesting. After this article, you’ll be able …
The diamond-square algorithm is a procedural terrain generation algorithm. It makes it easy to generate Heightmaps and Terrain for games. In this article we will implement the diamond-square algorithm in JavaScript, plot our terrain on a canvas and see how …
Collision detection is the basics of entities interaction on canvas. Imagine you have a Player Character (PC) that’s walking through a maze and you’d like to know if this PC bumps into a wall or can keep on going. One …
Generating a random map on a canvas is fun. In this article you will learn how to generate a random map or maze on an HTML5 canvas. We will use a model called Cellular Automaton.
While there are many ways …
