GameEngine() : isRunning(true) {
lastFrameTime = std::chrono::steady_clock::now();
}
void gameLoop() {
while (isRunning) {
auto currentTime = std::chrono::steady_clock::now();
float deltaTime = std::chrono::duration<float>(currentTime - lastFrameTime).count();
update(deltaTime);
render();
lastFrameTime = currentTime;
}
}
void update(float deltaTime) {
// Game logic updates
