Hi everybody,
I would like to create a struct in maxscript, send it to a SDK plugin, modify its values and send it back to maxscript. I have found several references but the code did not work. I am posting my tries in case you find some problems
Value* exposeStruct_cf(Value** arg_list, int count)
{
CHECK_ARG_COUNT(exposeStruct, 1, count);
four_typed_value_locals(String* p1, Integer* p2, Struct* s, Value* v);
Value* val = arg_list[0];
if (is_struct(val))
{
vl.s = (Struct*)val;
try
{
vl.v = vl.s->_get_property(n_param1);
}
catch (exception e)
{
UserThrownError(L"Excepcion capturada", TRUE);
}
//val->_get_property(n_param1)->to_string();
//vl.p1 = new String(val->_get_property(n_param1)->to_string());
}
return vl.p1;
}
six_typed_value_locals(Name* struct_name, StructDef* sd, Struct* s, Value** myParams, HashTable* members, Integer* i);
vl.members = new HashTable();
int member_count = 2;
vl.myParams = new Value*[member_count];
vl.myParams[0] = n_param1;
vl.myParams[1] = n_param2;
vl.members->put_new(n_param1, new Integer(0));
vl.members->put_new(n_param2, new Integer(1));
vl.struct_name = (Name*)Name::intern(L"myStruct");
vl.sd = new StructDef (vl.struct_name, member_count, vl.myParams, vl.members, NULL, NULL);
vl.s = new Struct(vl.sd, 200);
vl.s->_set_property( n_param1, new Integer(0) );
vl.s->_set_property( n_param2, new Integer(1) );
Thank you in advance

getting the values is easy enough, setting is a completely different ball game though.
def_visible_primitive(getStruct, "getStruct");
Value* getStruct_cf(Value **arg_list, int count)
{
check_arg_count(getStruct, 1, count);
Value* val = arg_list[0];
Value* structfield = Name::intern("testfield");
if(is_struct(val))
{
Struct* mxs_struct = (Struct*)val;
Value* temp;
if((temp = mxs_struct->definition->get_member_value(structfield)) != NULL)
{
int index = temp->to_int();
int ival = mxs_struct->member_data[index]->to_int();
return Integer::intern(ival);
}
}
return &undefined;
}
not as bad as I thought this will do it
def_visible_primitive(getStruct, "getStruct");
Value* getStruct_cf(Value **arg_list, int count)
{
check_arg_count(getStruct, 1, count);
Value* val = arg_list[0];
Value* structfield = Name::intern("anotherfield");
if(is_struct(val))
{
Struct* mxs_struct = (Struct*)val;
int ival = mxs_struct->_get_property(structfield)->to_int();
mxs_struct->_set_property(structfield, Integer::intern(ival + 1));
}
return &undefined;
}
then from mxs it would be
struct test (testfield, anotherfield)
obj = (test 10 10)
getStruct obj
obj
