Auvi objects in Javascript
I'm trying to create an Auvi object inside a js object, like so:
var abstract = new JitterObject("au.abstract");
...but receive the error:
missing arguments for message "au_abstract"
Outside of js, the object instantiates fine without any arguments.
For what it's worth, in the original Auvi C code, the class name is defined as "au_abstract" and the matrix calculation method as "jit_abstract_matrix_calc(...etc...)"
Thanks for your help,
Kurt
Hi Kurt,
As long as all of your functionality is in your Jitter class and not the Max wrapper class, the solution is simple, but it will require a recompile. You just need to make your jitter constructor typed--i.e. not A_CANT. So if you need to get arguments, you should use A_GIMME. If you don't take any arguments internal to your au_ class constructor, you can just remove the A_CANT.
For more details, please see the Jitter Object Model "constructor/destructor" section from the SDK.
https://cycling74.com/sdk/MaxSDK-5.1.1/html/chapter_jit_objectmodel.html
"In earlier versions of Jitter, the constructors were often specified as private and "untyped" using the A_CANT type signature. While this obsolete style of an untyped constructor will work for the exposure of a Jitter class to the patcher and C, it is now discouraged, as there must be a valid type signature for exposure of a class to Javascript or Java, though that signature may be the empty list."
Let us know if you encounter any problems.

Hi Joshua,
Thanks -- worked perfectly!
I will add this into the the next Auvi update (...which, realistically, might not be until the end of the year).
All best,
Kurt
