Thoughts on HTML5, a Flash Developers hopeless rant





















  My name is Yonny Zohar, I'm a game developer with six years experience. I've worked on several commercial titles including " Bingo Island ", and have recently made the move from flash development to html5.   Six years ago, while i was learning flash, i worked simultaneously with html, CSS and js. back then my impression was that flash was simply light years ahead in terms of development ease, code maintenance and error handling.   Returning now to html5 six years later, I was very weary - had things improved since 2009? I've spent the last several months hearing from everyone around me that the answer is a definite "YES". I'm here to say- the answer is still a definite NO!   Lets begin this rant with my number one hatred - CSS:   NO DEBUGGING -  Debugging css is awful. you spend days trying to figure out why elements don't behave the way they should. Try adding and removing properties to elements hoping it will make them act the way you want or

Pseudo 3d Isometric view




















תמונה







       Today i'd like to demonstrate another nifty use for pseudo 3d pixel manipulation - 3d isometric view!   We've all seen 2d games using isometric view, mostly popular in early strategy games like Age of Empires, or StarCraft. Rotating tiles 45 degrees creates the illusion of depth, which brings us closer to a 3d feeling.   However, using pixel manipulation and simple geometry we can do better and create a much richer sense of 3d.     The attached video shows a map created completely with 2d pixel manipulation, although it appears 3d. The effect is achieved by creating each image (building and tree) like a cake - layer by layer, with each layer getting a slight offset on the Y axis (known as sprite stacking). For example, the bottom layer of the tree will be drawn at its determined x and y, and the following layer will be at (x, y - 2).   Our tree is made up of 10 layers of stump, and 4 layers of green leaves. Our building uses 20 layers, some consisting of the same image,

         Inspired by news reports of the Corona virus I'm demonstrating how to create a simulation of what looks like cells or viruses under a microscope.     The attached video depicts what may appear to be microscopic organisms running around under a microscope. In Fact this is a bitmap canvas, drawn pixel by pixel, using a method that calculates the color for each pixel based on its distance from set points.     First we separate the canvas into logical rows and columns, creating an invisible grid. Then we select a random point in each tile, which will serve as the tile's reference point.     We then iterate over all the pixels in the canvas, and check each pixel's distance from its nearest reference points. We take the 2 closest points and sum them up to get the total distance from the first point to the pixel to the second point.     We then divide the distance to the closest point from the total distance to get the pixel's current percentage within that distance.
