sf::Rendertexture Collision Detection

[Qluxzz]

Hi there, I'm working on a little project in which i render a large tilemap. To save performance and don't having to draw 100x100 tiles each draw update, so instead i rendered the whole tilemap to a separate texture so i only have to draw one thing.

The problem I have is that I don't really know how to do collision detection with a large texture.

for (int x = 0; x < worldMap.size(); x++) {
                        for (int y = 0; y < worldMap[x].size(); y++) {
                int tileId = worldMap[y][x];
               // Get the width and height of the image
                int width = 64;
                int height = 64;
                // Adjust the offset by using the width and height of the image used      
                                caveTiles[tileId].setPosition(x * width, y * height);
                // Draw the tiles
                cave.draw(caveTiles[tileId]);
            }
        }
 

This code is for drawing all tiles to the texture.

Thanks in Advance.

You still have your tile data in memory. So what prevent you from doing you collision detection on these tiles?

I am actually rendering each and every tile each iteration of the game loop. How did you store it and only have it display one?
