On today’s Corona Geek Hangout, Steven Johnson introduced us to vertex shaders as part 2 of our introduction the topic of creating and working with custom shader effects. We looked at several working shader playground examples and learned a tip for using wireframe mode with display.setDrawMode to see the points of a polygon in a vertex shader example.
Last week on Corona Geek Hangout 148, we stepped through the concepts and source code to create a motorized wheeled cart using pivot joints and Corona’s built in physics engine. We also explored applying torque and gravity to the cart to get some interesting effects. Here are clips to help you catch up. Download the examples from the Hangout to see how everything works.
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.
