SFML: Va chạm trên tile map?

[Tieuyentu (Nguyen yen)]

e có class tilemap như vậy mọi ng cho e hỏi làm sao để khi pacman va chạm với gold thì gold k xuất hiện nữa ạ?

#include "tilemap.h"
#include "player.h"
////////////tile.map/////////////
void generateMap(sf::RenderWindow &appWindow, sf::Sprite &pacSprite, direction &nextDirection, direction &key)
{
	sf::Texture tileTexture_block;
	sf::Texture tileTexture_gold;

	tileTexture_block.loadFromFile("tile.png");
	tileTexture_gold.loadFromFile("gold.png");

	sf::Sprite tile_block;
	sf::Sprite tile_gold;

	tile_gold.setTexture(tileTexture_gold);
	tile_block.setTexture(tileTexture_block);

	std::vector < std::vector<int> > tilemap;
	tilemap.resize(100, std::vector<int>(100, 0));
	int speed = 4;
	std::ifstream openfile("Map2.txt");
	if (openfile.is_open())
	{
		std::string line;
		int lineCount = 0;
		while (std::getline(openfile, line))
		{

			for (int column = 0; column < line.length(); column++)
			{
				if (line[column] == '1')
				{
					tilemap[lineCount][column] = 1;
				}

				if (line[column] == '2')
				{
					tilemap[lineCount][column] = 2;
				}

				lineCount++;
			
			}
		}
	}


	//MAP DRAWING AND COLLISION
	for (int i = 0; i<tilemap.size(); i++)
	{
		for (int j = 0; j < tilemap[0].size(); j++)
		{
			if (tilemap[j][i] == 1)
			{
				tile_block.setPosition(i * 32, j * 32);
				appWindow.draw(tile_block);
				if (tile_block.getGlobalBounds().intersects(pacSprite.getGlobalBounds()))
				{
					if (nextDirection == none)
					{
						switch (key)
						{
						case up:
							pacSprite.move(0, speed);
							break;
						case left:
							pacSprite.move(speed, 0);
							break;
						case right:
							pacSprite.move(-speed, 0);
							break;
						case down:
							pacSprite.move(0, -speed);
							break;
						default:
							break;
						}
					}
					else
					{
						switch (key)
						{
						case up:
							pacSprite.move(0, speed);
							break;
						case left:
							pacSprite.move(speed, 0);
							break;
						case right:
							pacSprite.move(-speed, 0);
							break;
						case down:
							pacSprite.move(0, -speed);
							break;
						default:
							break;
						}
						key = nextDirection;
						nextDirection = none;
					}


				}

			if (tilemap[j][i] == 2)
			{
				tile_gold.setPosition(i * 32, j * 32);
				appWindow.draw(tile_gold);
				if (tile_gold.getGlobalBounds().intersects(pacSprite.getGlobalBounds()))
				{
					
					///////????????????????????????////
				}
