The guide to implementing 2D platformers Having previously been disappointed by the information available on the topic, this is my attempt at categorizing different ways to implement 2D platform games, list their strengths and weaknesses, and discuss some implementation details. The long-term goal is to make this an exhaustive and comprehensible guide to the implementation of 2D platform games. If you have any sort of feedback, correction, request, or addition – please leave it in the comments! Disclaimer: some of the information presented here comes from reverse engineering the behavior of the game, not from its code or programmers. It’s possible that they are not ACTUALLY implemented in this way, and merely behave in an equivalent way. Also note that tile sizes are for the game logic, graphical tiles might be of a different size.
Polygonal Map Generation for Games I wanted to generate interesting game maps that weren’t constrained to be realistic, and I wanted to try some techniques I hadn’t tried before. I usually make tile maps but instead used a different structure. What could I do with 1,000 polygons instead of 1,000,000 tiles? The distinct player-recognizable areas might be useful for gameplay: locations of towns, places to quest, territory to conquer or settle, landmarks, pathfinding waypoints, difficulty zones, etc.
Creating Custom Form Checkboxes and Radio Buttons with Just CSS! In CSS we have many ways to style things in any way we want. When it gets to forms though, things get a little complicated. Text inputs are easy, but checkboxes and radio buttons are very difficult to style with CSS. Using Custom Data Attributes and Pseudo-Elements A tutorial on how to (ab)use custom data attributes and pseudo-elements for creating image captions. In today’s tutorial I want to show you some simple CSS tricks using data attributes and pseudo-elements. The aim is to create an image caption using only an anchor and an image as markup. We’ll be exploring how to create pseudo-elements from some data attribute values and use them in a hover effect or simply show them next to the image. Embedded Security CTF Scattered throughout the world in locked warehouses are briefcases filled with Cy Yombinator bearer bonds that could be worth billions comma billions of dollars. You will help steal the briefcases. Cy Yombinator has cleverly protected the warehouses with Lockitall electronic lock devices.
