How to use SDL_KeyCode to handle a key press each time? - c++

Question

I'm trying to generate a rectangle into a new position whenever I press the Right arrow key, I was able to get the 1st rectangle but now stuck at the 2nd one. As this is not a case of SDL_GetKeyboardState (to move the rectangle when key is pressed continuously), I'm completely clueless on how this should proceed. To create array for rectangles and pass it to poll event?
const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;
SDL_Window *window = NULL;
SDL_Surface *screen = NULL;
SDL_Renderer *renderer;
SDL_Event e;
SDL_Rect one, two;
bool quit = false;
void init(){
SDL_Init(SDL_INIT_VIDEO);
window = SDL_CreateWindow("Testing", SDL_WINDOWPOS_UNDEFINED,
SDL_WINDOWPOS_UNDEFINED,
SCREEN_WIDTH, SCREEN_HEIGHT,
SDL_WINDOW_SHOWN);
renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
screen = SDL_GetWindowSurface(window);
}
void draw(){
SDL_SetRenderDrawColor(renderer,255, 255, 255, 255);
SDL_RenderClear(renderer);
SDL_SetRenderDrawColor( renderer, 255, 0, 0, 255);
SDL_RenderFillRect( renderer, &one);
SDL_SetRenderDrawColor( renderer, 0, 66, 255, 255);
SDL_RenderFillRect( renderer, &two);
SDL_RenderPresent(renderer);
}
void logic(){
Uint8 *state;
while (SDL_PollEvent(&e) !=0) {
if (e.type == SDL_KEYDOWN)
{
switch (e.key.keysym.sym)
{
case SDLK_RIGHT:
one = {2,2,124,124};
//two = {130,2,124,124};
break;
case SDLK_LEFT:
one = {0,0,0,0};
break;
}
}
else if (e.type == SDL_QUIT)
{
quit = true;
}
}
}
int main(int argc, char* args[]){
init();
while (!quit)
{
logic();
draw();
}
SDL_DestroyRenderer(renderer);
SDL_DestroyWindow(window);
renderer = NULL;
window = NULL;
SDL_Quit();
return 0;
}
