# Learn SDL2 in 1 Hour!

Wanna learn SDL2? You can learn it here!

## Step 1: Set Up Your Build Environment

Install SDL2 and, um, probably SDL_image if you're unlucky, and also use brew and the official installation for maximum compatibility, not like that will do anything bad (forshadowing). Then copy and paste this code into a file called Makefile or else:

```Makefile

main: $(wildcard *.cpp)

	g++ $(wildcard *.cpp) -o main -F/Library/Frameworks -framework SDL2 -std=c++17 -Wl,-rpath,/Library/Frameworks

```

## Step 2: Make Sure You're Running This On A Mac

If you are running this on a non-Mac, then, um, bad things will happen. Also try to replicate step 1 exactly, if you get my drift.

## Step 3: Copy the File

Should be the easiest step; this is just as comprehendable as, um, Spanish?

```cpp

#include 

#include 

using namespace std;

int main(int argc, char* argv[]) {

    if (SDL_Init(SDL_INIT_VIDEO) < 0) {

        cerr << "Failed to initialize SDL: " << SDL_GetError() << endl;

        return -1;

    }

    SDL_Window* window = SDL_CreateWindow(

        "Lego Island 2D Clone",

        SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED,

        800, 600,

        SDL_WINDOW_SHOWN

    );

    if (!window) {

        cerr << "Failed to create window: " << SDL_GetError() << endl;

        SDL_Quit();

        return -1;

    }

    SDL_Renderer* renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);

    if (!renderer) {

        cerr << "Failed to create renderer: " << SDL_GetError() << endl;

        SDL_DestroyWindow(window);

        SDL_Quit();

        return -1;

    }

    bool running = true;

    SDL_Event event;

    while (running) {

        while (SDL_PollEvent(&event)) {

            if (event.type == SDL_QUIT) {

                running = false;

            }

        }

        SDL_SetRenderDrawColor(renderer, 255, 0, 0, 255);

        SDL_RenderClear(renderer);

        SDL_RenderPresent(renderer);

        SDL_Delay(16);

    }

    SDL_DestroyRenderer(renderer);

    SDL_DestroyWindow(window);

    SDL_Quit();

    return 0;

}

```

## Step 4: Run This Command

`make; ./main` If this fails, good luck! Ok bye for now!
