I’m trying setting the background color to blue using glClearColor(), but it seems not working …
I tried deleting GL_DEPTH_BUFFER_BIT or writing glClearColor() inside drawGame(), but nothing…
void MainGame::initSystem() {
SDL_Init(SDL_INIT_EVERYTHING);
SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
_window = SDL_CreateWindow("Game Engine", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, _screenWidth, _screenHeight, SDL_WINDOW_OPENGL);
if (_window == nullptr) {
fatalError("SDL Window could not be created!");
}
SDL_GLContext glContext = SDL_GL_CreateContext(_window);
if (glContext == nullptr) {
fatalError("SDL_GL cointext could not be created!");
}
GLenum error = glewInit();
if (error != GLEW_OK) {
fatalError("Could not initialize glew!");
}
glClearColor(0.0f, 0.0f, 1.0f, 1.0f);
}
void MainGame::drawGame() {
glClearDepth(1.0);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
SDL_GL_SwapWindow(_window);
}
It should color the background with blue, but the color is white.
