[ad_1] So it looks like you have this: struct Obj { int x_; }; template <typename T> struct Struct { std::vector<T> items_; }; So to access an element (assuming you added it to the vector): int main() { Struct s; s.items_.resize(10); s.items_[0].x_ = 5; // Access the object memeber of element 0 in the vector. … Read more
[ad_1] A member is some entity that belongs to a class. If a class has a function, this is a member function – you might know it as “a method”. If a class has a variable, this is a member variable – you might know it as “a property”. int a; void f () {}; … Read more
[ad_1] It seems you want to pass a non-type template parameter, and more specifically, a pointer-to-member. For what you want, you have to user: template<ObjectType gameclass::* ptr> struct foo // … Note that will allow you to access the member of an object only if you have a pointer to that object. You can have … Read more
[ad_1] Are you sure the definition is actually defining function onChar in class Game and not in class Screen? If you accidentally wrote this as the definition for onChar (which I can imagine could easily happen): void Screen::KeyListener::onChar(char c) {} then you are defining function in class Screen. [ad_2] solved is there an equivalent to … Read more
[ad_1] As the compiler is telling you, this line: Note n = Note(&track.generator); Tries to construct a Note and supply a Generator** to its constructor (since track.generator has type Generator*, &track.generator has type Generator**). However, your Note class constructor accepts a Generator*, not a Generator**. Just do this instead (notice, that copy-initialization is unnecessary here, … Read more
