How to make a Snake Game using JavaScript and html5

-

I compiled stapes to create a game similar to Nokia developed, popular game called 'snake' Snake was first developed by Nokia, programmed in 1997 by Taneli Armanto and published on Nokia mobile devices,  It was introduced on Nokia model 6110, 3310 from 2000 and later the game was rebranded as " Snake Xenzia " Included on later mobile phone models I made a version that is more simplified and more beginners friendly, It's based on the same idea of making a snake that grows as it eats stuff and the score increases as it grows I'm implementing this whole game in pure vanilla JavaScript and a taste of html5 canvas, In this project the canvas is used as a renderer for the game's visual output concepts and initial ideas I got the idea while doing another retro gaming project, i thought it would be good too if i created this game, from start my plan had been simplicity and making this game easy to implement, So to simplify everything i had...

FlappingBird was my Primary entry for JS13K Games competition 2020 It's about a bird flying in a forest of trees (Some of which are upside down) It started out as i was trying to draw some clouds for fun, then later i added every missing component to complete the sky First day. I planned making a game that should as well serve as a 404 page with a hidden game such that when a button is pressed It transitions into gameplay qualities were that it should be easy to play by everybody without need to master many rules Second day. There was a bunch of game ideas up my sleeves one of them was a game where a typical 404 page transitions into a green garden like mine sweeper version made up of a flowering mine field with smooth sweet sound effects Fourth day. We'll Since Mine sweeper is not a very common game there's nothing fun about it and not everyone knows how it's played. So i gave up on it and on this day i started working on backgrounds for flappingBird "the final...

How to make a html5 breakout game in JavaScript

-
In this tutorial i will walk through the  process of developing a simple breakout game in JavaScript using html5 canvas I'll be using craters.js a compact html5 game engine. in every step i will first explain the procedure in a less technical method later I'll include the snippets of the actual game , a link to the github repository and a live working demo. Game world is 2d space with zero friction and zero gravity in order to avoid applying acceleration to the entities periodically maybe this will be changed later. First entity is a ball an entity with zero friction that upon colliding with an obstacle such as a block, paddle or the the screen boundaries bounces back in the opposite direction the bouncing from left to the right side of the screen is implemented by if(position.x  + radius < 0) // bounce if(velocity > 0) return; // moving velocity *= -1; // change direction direction is only changed if the ball tries to move  beyond the zero position. i have t...

Zedplug will be decommissioned on November 30th

-
Greetings to each and every one of you. I am writing this letter to inform you that Zedplug will be decommissioned on November 30th. With the goal of becoming the authoritative source of Zambian music, Zedplug began development in November 2019 and was released on February 18, 2020. Since then, Zedplug has worked tirelessly to achieve its objective of being Zambia's leading music distributor. Throughout Zedplug's history, we've had our fair share of good and horrible times, but we've always been committed to keeping Zedplug up and operating. Among other notable milestones, we've had the opportunity to interact with well-known performers. Zedplug has reached the end of its life cycle. I've made my money, and I feel it's time for me to pull the plug on Zedplug. (Please permit me to serve as your master of ceremonies at this moment.) This is how the dismantling will go down. Recap from a few weeks ago: We halted our routines and refused to distribute any music....
