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 problem with the SWF file. You can play the original SWF file by clicking on this link.
