This might be a very simple fix, but I've been fighting this for more
hours than I care to admit to.
std.typecons says "Tuple of values, for example Tuple!(int, string) is a
record that stores an int and a string. Tuple can be used to bundle
values together, notably when returning multiple values from a function."
But when I try this in practice with
// typedef std::tuple<GLboolean, Direction, glm::vec2> Collision; //
porting C++ to
Tuple!(GLboolean, Direction, vec2) Collision;
Collision is a variable. Did you mean
alias Collision = Tuple!(GLboolean, Direction, vec2);
Collision CheckCollision(BallObject one, GameObject two) // AABB -
That won't work because you should have a type instead of Collision (a
variable).
Circle collision
{
DMD 2.071.0, keeps returning at the function signature:
Error: functions cannot return a tuple
I've also tried,
alias Collision = AliasSeq!(GLboolean, Direction, vec2);
but same error.
Am I doing anything stupid here?
thanks.
And yes, functions can return tuples: :)
import std.typecons;
struct S {
int i;
}
Tuple!(int, S) foo() {
return tuple(42, S(43));
}
void main() {
auto a = foo();
}
