Maybe today I'm confused and I'm missing the obvious...

I've made this simple struct inside my Utility.h 

template<typename TFirst, typename TSecond>
	struct Pair {
		Pair(TFirst f, TSecond s):First{f},Second{s}{}
		TFirst First;
		TSecond Second;
	};

And I'm using it from App.h (which #include "Utility.h") like so:

App.h

Pair<Uint32, Uint32> GetWindowSize();

App.cpp

Pair<Uint32, Uint32> App::GetWindowSize()
{
	return Pair<Uint32, Uint32>(Width,Height);
}

And I'm getting a cascade of errors ALL on line 39 (image below).

Any idea what I am doing wrong this time? x_x

EDIT: please mod delete this topic, I just remembered Utility.h put everything inside namespace util, sorry x_x

I didn't wanted to have to add another include in all my files in order to use that, since I already had my Utility.h included I put my class inside of that. There is a way to add the std::pair to my Utility.h so that all files including it get to use std::pair without including anything else?

A size is a conceptually richer concept, which includes a different set of operations and relationships than the more-generic "pair" concept

I don't fully understand this, I basically just needed to pass around width and height so that I can spawn my Entities like so(code below:

EDIT: by the way, why the code below is being pasted in this crazy way?!  Maybe a problem in how the tab character is interpreted?

It should appear like this --> https://pastebin.com/iddWWWfH

GameMode::GameMode(SDL_Window* Window, SDL_Renderer* Renderer, App* App)
	:Window{ Window }, Renderer{ Renderer }, AppRef{ App }, Running{ true }
{
	float WindowWidth = static_cast<float>(AppRef->GetWindowSize().First);
	float WindowHeight = static_cast<float>(AppRef->GetWindowSize().Second);
	
	//PhysicsManager
	PhysicsManager = std::make_unique<Physics>(this);

	//Create Player
	Entities.push_back(std::make_unique<Paddle>(this,
												static_cast<int>(WindowWidth) / 2,
												static_cast<int>(WindowHeight) - 40,
												PivotMode::CENTER));

	//Boundaries
	//Right
	Entities.push_back(std::make_unique<Boundary>(this,
												  Rect{ WindowWidth - 5.f, 0.f,
													   50.f, WindowHeight },
												  PivotMode::CENTER));
	//Left
	Entities.push_back(std::make_unique<Boundary>(this,
												  Rect{ -45.f, 0.f,
												  50.f, WindowHeight },
												  PivotMode::CENTER));
	//Top
	Entities.push_back(std::make_unique<Boundary>(this,
												  Rect{ 6.f, -45.f,
												  WindowWidth - 12.f, 50.f },
												  PivotMode::CENTER));

	//Bottom
	Entities.push_back(std::make_unique<Boundary>(this,
												  Rect{ 6.f, WindowHeight - 5.f,
												  WindowWidth - 12.f, 50.f },
												  PivotMode::CENTER));

	//Create Ball
	Entities.push_back(std::make_unique<Ball>(this,
											  static_cast<int>(WindowWidth) / 2,
											  200,
											  PivotMode::CENTER));
}

It is, a TAB character is defined to aligned at multiples of 8 characters, in ASCII. Most editors ignore this definition, and allow you to change it, giving the illusion that a TAB is whatever you configured. That of course fails as soon as your file leaves your editor, since other programs or other people use different TAB settings, or use the official size.

though this pastes correctly on codeshare.io and pastebin and Windows blocknote and pretty much everywhere else... wouldn't be better to have the site behaving the same way?

ok, so the bottom line is I should either return a Struct filled with info with inside appropriete variables names like WindowInfo.width and WindowInfo.height or split it into two methods Game->GetWindowWidth() , Game->GetWindowHeight()

Did I got this right?

By the way, I added this as well into Utility.h

	template <typename First, typename Second>
	using Pair = std::pair<First, Second>;

and I'm glad to see it everything still compiles without any changes required

Fixed, thanks
