Corona Geek #146 – Creating Draggable Rag Dolls, Using Physics Bodies, and Creating Joints

Corona Geek #146 – Creating Draggable Rag Dolls, Using Physics Bodies, and Creating Joints

Corona Geek

Last Monday we looked at creating library extensions, and loading and saving data using JSON to persist states between app uses.

Today we cracked open the can of joy that is the Box2D physics engine. We created a Draggable Rag Doll, used physics bodies, touch joints, and pivot joints.  Then, we raced into motors and made a simple two wheeled car.

We’ll be breaking down the physics code over the next several weeks. Let us know if you have any questions about the code or concepts along the way. Download the code from today’s discussion.

Let’s Play Alone for June’s Corona Geek Games Challenge

Don’t forget, this month we’re playing Alone by Laser Dog Games for the chance to win a $50 gift card. ALONE is available on both iOS and Android as a paid app.

If you’d like to participate in June’s challenge with a free game option, play One Dot One Target on iOS or Android.

Each game has either levels or difficulty settings, so June’s high score winner will the announced based on high score as well as highest level completed or highest difficulty level played. Basically, more is better. 

To participate, share a picture of your highest score on the Corona Geek Facebook page.

We’ll announce July’s Geek Game Challenge on social media. So be sure to follow CoronaGeek on at least one of your favorite social channels ( Facebook, Twitter, Google+ ).
