Corona Geek #148 – Creating Motorized Wheeled Carts Using Pivot Joints

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 Character Using Pivot Joints and Physics Bodies

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.


Hangout Highlights – How CBEffects Author Caleb Place Created A Particle Effects Library

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.
