Corona Geek #81 – Using applyForce, applyTorque, and HTML5

Corona Geek Hangout

During this week’s Corona Geek Hangout we discussed concepts from the Physics API like applyForce and applyTorque. Roaming Gamer’s Ed Maurina stepped us through examples of each concept and explained how they affect game objects. Spiral Code Studio’s Sergey Lerg also walked us through how he ported his Cubic Run LD game code to HTML5 using Corona SDK.


Corona Geek #53 – Make Rain and Lightning in Corona SDK

Corona Geek Hangout

During this week’s Corona Geek, it almost literally rained cats and dogs during the rain and lightning code snippet walkthroughs. We walked through a great piece of code by Corona Ambassador Volodymr Sergeyev, that showed how to create and recycle objects to simulate rain. Ed Maurina modified that code on the fly and the results will make you laugh out loud.


Corona Geek #52 – Making a Character Jump in Corona SDK

During this week’s Corona Geek Ed Maurina, developer of Corona SDK game templates at Roaming Gamer, walked us through a Corona SDK code snippet that makes your game characters jump. Using Corona’s built in physics engine, we applied force to a single character and then added a second character to show how easy it is to handle touch events for multiple objects using the same function.


Tutorial: Non-Physics Collision Detection

Corona SDK has a robust physics-based collision detection system, but it requires some extra processing behind that scenes that you typically don’t need if you’re not using physics for other purposes. Today’s tutorial explains how to detect collisions between two circles or two rectangles without using the physics engine. Read further to learn how.


App of the Week: Plasma Pig

When Pigsley, the cartoony pig, is transported to Planet Lardo, he’s in real danger. The planet is run by an evil overlord that would love nothing more than to turn Pigsley into a delicious pile of bacon.


Tutorial: Raycasting and Reflection

A few weeks ago, raycasting was added to Corona’s physics system. The core API is an easy-to-use function for casting a “sensor ray” into the physics world — and we didn’t stop with that. Soon after, reflection was added to the raycasting system. Today’s tutorial discusses both of these features and includes a downloadable demo project to assist with your own development.
