Hi,
@0x8bc5b84ae7dd5db8;
struct Game{
id @0 :UInt32;
c1 @1 :List(UInt32);
c2 @2 :List(UInt32);
t @3 :List(UInt32);
balls @4:List(UInt8);
cardState @5:CardStateMap;
cardIndexByNumber @6:Data;
}
struct CardStateMap {
contents @0:List(KV(UInt8,CardState));
struct CardState{
r1 @0:UInt8;
r2 @1:UInt8;
r3 @2:UInt8;
}
}
struct KV(K,V){
k @0:K;
v @1:V;
}
the code above is the exact code from my file and when I try to compile
I get the following error

Hi Nikos,
If you'd like us to help you, you need to provide the exact code you
actually wrote, and the exact error it produced.
The code you provided in your first e-mail has numerous syntax errors
such that it can't compile as-is. When I fixed those errors, it
worked fine. That is, if I put the following in a file and compile
it, I get no errors:
@0xc39ccf0ba082696f;
struct Foo(A) {
field @0 :A;
}
struct B {}
struct C {
field @0 :List(Foo(B));
}
So, I do not know what problem you are actually having.

I need a List(foo(b)) that is the problem capnp compile command
generates an error sayingI need to pass pointers rather than b itself
so I cant compile my schema because it need a pointer type at
compile time and you are saying there is no such thing in capnproto
which makes using generics impossible in nested levels as i
understand

"Pointers" aren't an explicit thing in the schema language. Data,
Text,
structs, lists and interfaces are implicitly pointers, while
primitive
types like Bool and Float64 are not. Type parameters must always be
pointer types. So in this case you can just do:
struct Foo(A) {
field @0 :A;
}
struct B{};
struct C {
field :List(B);
}
