Python Screencast: Arinoid - Ball Physics

You may notice some mistakes in the screenshots - in particular when the code that converts between integers and floating point numbers is displayed. The highlighted code is correct, but the way that it appears in the following slides (without the float and int conversions) is incorrect. Note that this video does not stream in the player above (unlike most of our ShowMeDo videos), due to a prob...

Python Screencast: Arinoid - The Paddle

Posted in Development

Here we will be adding the first sprite in our game, the paddle, which is controlled using the mouse. At this point, we will be able to benefit from the setting-up that we have done in the first two screencasts. Note that this video does not stream in the player above (unlike most of our ShowMeDo videos), due to a problem with the SWF file. You can play the original SWF file by clicking on this...

Python Screencast: Using Sprite Sheets and Drawing the Background

Posted in Development

To run the code for this screencast, you will need to have a data subdirectory containing the Arinoid sprite sheet file. You can easily fulfill this requirement by downloading the arinoid source from the post on Arinoid. Also, this will be needed for most, if not all, of the upcoming screencasts. Note that this video does not stream in the player above (unlike most of our ShowMeDo videos), due ...

Java Tutorial: Animated Mandelbrot fractal applet - Part 8

Java Tutorial: Animated Mandelbrot fractal applet - Part 8

Posted in Development

Half of creating a nice interactive applet is ensuring that things at least appear to be happening. So rather than rendering the entire Mandelbrot fractal in one go, John demonstrates how it can be rendered in parts. John uses a 'dissolve' to bring in the Mandelbrot as it is rendered. There is also a nice example here of the difference in performance that can occur by choosing a suitable data s...
