What am I doing wrong here? This is lifted code. When the program runs it produces a black screen with a geometric pattern which is fine. But it sticks, it can only abort with task manager:
Second, it has no border (which is what I want) but I would like to be able to toggle that rather than just watch it disappear b/c I use use 1920 x 1080 res.
Code:
#include<iostream>
#include<SDL.h>
using namespace std;
int main(int argc, char* argv[])
{
if (SDL_Init(SDL_INIT_VIDEO) == 0) {
SDL_Window* window = NULL;
SDL_Renderer* renderer = NULL;
if (SDL_CreateWindowAndRenderer(1920, 1080, 0, &window, &renderer) == 0) {
SDL_bool done = SDL_FALSE;
while (!done) {
SDL_Event event;
SDL_SetRenderDrawColor(renderer, 0, 0, 0, SDL_ALPHA_OPAQUE);
SDL_RenderClear(renderer);
SDL_SetRenderDrawColor(renderer, 0, 0, 255, SDL_ALPHA_OPAQUE);
SDL_RenderDrawLine(renderer, 320, 200, 300, 240);
SDL_RenderDrawLine(renderer, 300, 240, 340, 240);
SDL_RenderDrawLine(renderer, 340, 240, 320, 200);
SDL_RenderPresent(renderer);
while (SDL_PollEvent(&event)) {
if (event.type == SDL_QUIT) {
done = SDL_TRUE;
}
}
}
}
if (renderer) {
SDL_DestroyRenderer(renderer);
}
if (window) {
SDL_DestroyWindow(window);
}
}
SDL_Quit();
return 0;
}
