Approach

The concentration of the e-book is on sensible difficulties and the way to unravel them in Python. The examples given are helpful courses that attempt to clear up real-world wishes. every one bankruptcy revolves round a unmarried notion giving a number of examples progressively starting to be in hassle. each one part analyses the matter first earlier than diving into coding and offers huge historical past info to let the reader to generalize from the categorical challenge to a much broader diversity of demanding situations. The pattern code is supplied as absolutely operating examples with all key concerns widely highlighted. All pattern courses are transparent and concise but not anything crucial is skipped over and the programming type makes a speciality of clarity instead of on stylistic rigor or potency.

Example text

15 ] Extending Blender with Python You can select the built-in editor by choosing Text Editor from the Windows menu: When you start up you are presented with an almost empty area except for a strip of buttons at the bottom: We can select the default empty text buffer TX:Text or create a new empty text by selecting ADD NEW from the drop-down menu available when we click on the Menu button. 001, but you may change it to something more meaningful by clicking on the name and changing it. ) the name of the text is distinct from the filename (although in general it is a good idea to keep these the same to avoid confusion).

Then we export these meshes as Python code by using a script that we encounter again in the next chapter as it deals with vertex groups. For now, we use this generated Python code simply as a module containing several lists of vertices defining each body part. blender\scripts\bpymodules would be a logical choice or alternatively the user scriptdir. PupBlock() [ 37 ] Creating and Editing Objects This is somewhat limited compared to full-fledged libraries available for some programming languages, but very easy to use.

This pop up merely shows a message on an alarmingly colored background but illustrates nicely how user actions (such as key presses or button clicks) are linked to the graphical elements. Register(lambda:msg(text), event, button_event) [ 40 ] Chapter 2 The error() function is where it all starts and ends for the user; it tells Blender what to draw, where to send events such as button clicks, where to send key presses, and starts the interaction. Register() to draw things cannot take an argument, yet we want to pass a different text argument every time we call error().
