Hey'all!
I've been trying to understand how to share one objects variables with others,
i.e. to have a storaging object that others can access (it's possible, right?),
like [value] does, so that the first object would hold the data globally like
an array, and the other one(s) could have pointers to its variables and thus
change the values directly. So what I need is a way to deliver pointer of one
objects data to the other. I can't get the other, reading, object to read the
value correctly. I haven't been able to find much documentation concerning
pd_findbyclass and how the symbol system actually works under the hood, so if
anyone could kindly point me towards any or explain what I'm missing here:
STORAGING OBJECT:
#include "m_pd.h"
static t_class *aset_class;
typedef struct _aset {
t_object x_obj;
t_pd x_pd;
t_int x_i;
} t_aset;
void *aset_new(t_symbol *s)
{
t_aset *x = (t_aset *)pd_new(aset_class);
x->x_i = 34;
pd_bind(&x->x_pd, s);
post("control %i", x->x_i);
return (x);
}
void aset_setup(void) {
aset_class = class_new(gensym("aset"),
(t_newmethod)aset_new,
0, sizeof(t_aset),
CLASS_DEFAULT,
A_SYMBOL, 0);
}
----------------------------------
READING OBJECT:
----------------------------------
#include "m_pd.h"
#include "aset.c"
static t_class *aget_class;
typedef struct _aget {
t_object x_obj;
t_pd x_pd;
} t_aget;
void *aget_new(t_symbol *s)
{
t_aget *x = (t_aget *)pd_new(aget_class);
t_aset *c = (t_aset *)pd_findbyclass(s, aset_class);
post("read %i", c->x_i);
return (x);
}
void aget_setup(void) {
aget_class = class_new(gensym("aget"),
(t_newmethod)aget_new,
0, sizeof(t_aget),
CLASS_DEFAULT,
A_SYMBOL, 0);
}
Cheers!
Olli
