Corona Geek #148 – Creating Motorized Wheele...

On today’s Corona Geek Hangout we learned how to build a motorized wheeled cart using Corona’s built-in physics engine and pivot joints. We explored why you should consider adding display objects to a group and how torque affects different parts of a wheeled physics simulation. We also explored ideas for using a wheeled cart in a game. Download the source code from today’s discussion.

Corona Geek #147 – Creating A Rag Doll Chara...

Last Monday we started a series on working with Corona’s built-in physics engine. We took a look at the Physics API documentation and we discussed the concepts behind constructing a rag doll from primitive shapes. This week we continued the physics conversation with a look at the code used to create the rag doll example and tips on how to organize project code. We even discussed how a simple dress up, or object placement game could be constructed, using the sampler code as a reference.

Corona Geek #146 – Creating Draggable Rag Do...

Last Monday we looked at creating library extensions, 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 draggable rag dolls, used physics bodies, touch joints, and pivot joints.  Download the code from today’s discussion.

Corona Geek #145 – Creating Library Extensio...

Last Monday we showed how to short circuit the amount of work being performed between frames to improve the performance of touch based games. We also looked at creating radial dial timers using image masks. Today we looked at creating extending libraries, loading and saving JSON data, and persisting state across app sessions.

Hangout Highlights – How CBEffects Author Ca...

Last week on Corona Geek Hangout 143, we hung out with CBEffects particle effects library author Caleb Place. Caleb shared how he got started with programming at the age of 12 years old and how he taught himself the algebra needed to create particle effects. His story is really inspiring and proves that anyone can create amazing things regardless of age or experience. Here are clips from Hangout.
