Tutorial: Allowing Jump, Sticky Projectiles, Wind Tunnels

Today’s tutorial introduces a few new physics methods for your bag of tricks. We’ll solve the “Can I jump?” issue for 2D side-view games, and also discuss how to handle “sticky projectiles” and basic “wind tunnel” behavior. Three sample projects are available for download in order to study each case.

Tutorial: Basic Shape-Matching App

Educational and children’s apps continue to grow in popularity, as do casual puzzle games on various devices, especially with the new wave of family-oriented tablets. Today’s tutorial walks you through a basic multitouch shape-matching app and it includes the complete project code which you can implement into your own project.

Tutorial: Implementing Pinch-Zoom-Rotate

Many apps have a huge feature set but still function primarily with a single point of input: buttons, touch-drags, individual swipe actions, etc. However, even the most basic interface can benefit from the multitouch capabilities of modern devices; for example, zoom in and out on a background, scale/rotate objects and layers, etc. Today’s tutorial walks you through a full “pinch-zoom-rotate” methodology and includes a working module that you can incorporate into your own app.

Tutorial: Utilizing Time and Dates

Working with “time” in any programming language can be confusing to programmers. Furthermore, it’s not always obvious what the time and date functions mean and how they behave. This week’s tutorial discusses some of these issues and shows you how to work with things like date calculations, time zones, and date formatting.

Tutorial: Multi-Element Physics Bodies

This week’s tutorial steps you through some advanced tactics involving multi-element physics bodies. Mutli-element bodies possess some valuable traits that joint-assembled bodies don’t — but they also present some quirks and hurdles. Learn how to work around some of those in your physics-based apps!

Corona Holiday Gifts: Android Push and More!

Christmas came early for many Corona SDK developers! The team was very busy last week with a bunch of check-ins that rolled out to daily builds. There are many new features for you to explore, including native Twitter support (iOS 5 and 6), iAds support, and the much-anticipated Android push notifications. Please read about all of the holiday gifts that Corona has delivered today, and how to get started with push notifications in Android!

Device Detection

Developing for multiple devices and OS versions might seem tricky, but it’s easier if you build a comprehensive module to detect different hardware models. This week’s tutorial steps you through the entire process, allowing you to modify both content and capabilities depending on the actual device. Read further to learn how it’s done!
