maxmspjit

hi all, I'm having a bit of trouble wrapping my head around 

communication between the max wrapper and a jitter object. I would 

like to output a bang when the jitter object state meets certain 

criteria. this is complicated by the fact that I'm trying to do this 

in gl, as it seems the usual trick is to supply a manual mproc 

function and do some setup / postflight there.

my best guess so far is that I have to do something with 

jit_object_method and _jit_sym_getoutput, but I'm not entirely clear 

what incantation is necessary to pull this all together. do I need to 

pass a pointer to the max object to the jitter object?

I found some code jeremy wrote that looks like this:

void *mop = jit_class_adornment_get(_myobject_class, _jit_sym_jit_mop);

void *o = jit_object_method(mop, _jit_sym_getoutput, 1);

but I don't believe I have a mop as it is a gl object. is there

something similar I can use?

If you really want to, you can pass in your max object wrapper to 

your inner jitter class however you see fit, though it is not 

recommended so that your class is useful from within JS, Java, and 

any future language bindings. Typically we recommend this sort of 

communication via jit_object_notify. This can notify the client max 

wrapper object (or JitterListener in JS/Java), to do something like 

send data out an outlet mid-process. In the SDK this is discussed a

As for getting access to the outlet pointers, you can cache the 

results of outlet_new in your max wrapper object struct for things 

max_jit_obex_dumpout_set(x, outlet_new(x,NULL));

max_jit_ob3d_attach(x, jit_ob, outlet_new(x, "jit_matrix"));

x->matrixout = outlet_new(x, "jit_matrix");

max_jit_ob3d_attach(x, jit_ob, x->matrixout);

Or you could create additional outlets if you prefer.
