I was making a game in C++ , SFML. so I made the Game Engine but then I decided to make the Player and PlayerController classes. The game with the Player class works perfectly but when I include the PlayerController class which listens to keys pressed and moves player, it says this error: syntax error: identifier. main.cpp:
#include "GameEngine.h"
int main() {
GameEngine game;
game.run();
return 0;
}
Game Engine h file:

class GameEngine
{

float getDeltaTime();
void update(); // later

}
void GameEngine::constructWindow()
{

{

//Render stuff in between

mainPlayer.constructPlayer();
mainPlayer.drawPlayer(win);
PlayerController cont;
mainPlayer.updatePlayer(cont);
win->display();
}
void GameEngine::handleSFMLEvent()
{
while (win->pollEvent(this->sfmlEvent)) {
if (sfmlEvent.type == sfmlEvent.Closed)
win->close();

float GameEngine::getDeltaTime()
{
deltaTime = deltaTimeClock.restart().asSeconds();

}
Finally the error:
Thank you :3 Sorry if there had been already a similar question. I am new to here. I am selflearning and have no clue of the tutorials on Youtube or other platforms.
