Jython treats any Java’s non- public members as if they were full-force private, regardless whether they have protected or “Package” more liberal access levels.Īlthough reflection techniques are “clever”, these 3 statements aren’t that hard to grasp IMO: fieldX = Function.getDeclaredField('x')īelieve me, if that field x were private instead of the less restrictive protected, the Java version would have a much bigger boilerplate for us to code: import beads.* (and your trick is a bit too clever as it requires Java knowledge of protected variables) Super(FreqControl, f)._init_(*args, **kw)ĭef calculate(f): return f.xx * f.mul + f.aug ![]() VOff = int(cy * (1 + gain.getValue(0, i * siz / w)))ĭef keyPressed(): key = ESC and ac.stop() Modulator = WavePlayer(ac, FREQ, Buffer.SINE)Ĭarrier = WavePlayer(ac, FreqControl(modulator), Buffer.SINE) I’ve had to use reflection in order to access that Function:: x protected field.Īnd then stored it as an alias field named xx right after!

Extra info:įormatting your code makes everybody’s life easier, your code looks much better plus it ensures your code integrity is not affected by the forum’s formatting (Do you know the forum processes markup code?) Please visit the sticky posts or the FAQ section/post to learn about this, other advantages and super powers you can get in this brand new forum. You can edit your post, copy the code to the PDE, indent the code properly there and then past it back here, format the code and > save << the edits. That’s it! Please notice you do not create a new post in case you need to format something you already posted. ![]() Then you select the code and you hit the formatting button aka. You copy and paste your code in the forum.In the PDE, you use the key combination: ctrl+t Auto-indenting makes your code easier to read and helps catching bugs due to mismatch parenthesis, for instance. This function automatically indents your code. In your code editor (PDE, VS code, Eclipse, etc) ensure you execute the beautifier function. ![]() Return x*50+200 # <- x is not defined !!!įrequencyModulation = My_Function(modulator)Ĭarrier = WavePlayer(ac,frequencyModulation,Buffer.SINE) Return (x * 50.0) + 200.0 // <- works fine !Ĭarrier = new WavePlayer(ac, frequencyModulation, Buffer.SINE) then add 200, so that it varies from 150 to 250 multiplied by 50 to make the sine vary between -50 and 50 return x, which is the original value of the modulator signal (a sine wave) but they only override the calculate functionįunction frequencyModulation = new Function(modulator) custom functions are a bit like custom Unit Generators (custom Beads) I am stuck with FM synthesis, having to translate a CUSTOM FUNCTION (much used in the book) : modulator = new WavePlayer(ac, 5, Buffer.SINE) > Has anybody tried to translate in Python the Merz book, or better the 11 Lessons ? The beads library works fine in Processing.py up to some points where the Java does not seem obvious to be translated in Python. Hi ! I am starting to learn Beads audio library, wonderful book by Evan Merz but in Java.
