calling methods from another object

Oct 07 2009 | 3:58 pm

If anyone can help with the following….

I am trying to send a message from one object to another;
In my sending object I have the code;

atom_setlong(x->pparray, f);
object_method_typed(x->boundobject, gensym("tester"), 1, x->pparray, &rv);

and have also tried;

object_method_long(x->boundobject, gensym("tester"), f, &rv);

(boundobject is pointer to receiving object, f is long value).

In my receiving object I have the prototype –
void lh_trkmtx_tester(t_lh_trkmtx *x, long n);

and in main –
class_addmethod(c, (method)lh_trkmtx_tester, "tester",A_LONG, 0);

and the function –
void lh_trkmtx_tester(t_lh_trkmtx *x, long n)
post("message %i", n);
return ;

When testing I always receive the following in the max window everytime the sending method is triggered;
lh_trkmtx : doesn’t understand "tester"

When I create a message box to send the message in via inlet1 all works fine.
Am I trying to do something that you cannot do, or am I missing something obvious?
I successfully use the same method to send a "set" value message to a dial object,
Any help or enlightenment on this would be greatly appreciated… I ‘think’,,,.. this is my last programming stumbling block!

Kind Regards,

If anyone else comes across the same confusion, …. arranging the code like below in the sending object makes all work just fine –

atom_setsym(x->pparray, gensym("tester"));
atom_setlong(x->pparray+1, f);
object_method_typed(x->boundobject, gensym("message"), 2, x->pparray, &rv);
