This is the answer to the question. Handling keyboard input in SDL is straightforward using the SDL event system. You need to check for SDL_KEYDOWN and SDL_KEYUP events in your event loop. Here's a simple example that reacts to keyboard inputs:
#include <SDL.h>
int main(int argc, char** argv) {
SDL_Init(SDL_INIT_VIDEO);
SDL_Window* window = SDL_CreateWindow(
"Keyboard Input Window",
SDL_WINDOWPOS_UNDEFINED,
SDL_WINDOWPOS_UNDEFINED,
640, 480, 0
);
SDL_Event event;
bool running = true;
while (running) {
while (SDL_PollEvent(&event)) {
if (event.type == SDL_QUIT) {
running = false;
} else if (event.type == SDL_KEYDOWN) {
switch (event.key.keysym.sym) {
case SDLK_ESCAPE:
running = false;
break;
// Handle other key presses here
}
}
}
}
SDL_DestroyWindow(window);
SDL_Quit();
return 0;
}This code initializes an SDL window and processes keyboard input to close the window when the Escape key is pressed.
