Heyyy

I'm using a lib now that parses my map format and renders it with Vertices to the screen.

Thanks for your help tho

Yeah that was only a small test map.

Also each map has layers. And the tiles are 64 x 64 not 5x5.

5x5 was the Map Size (*64) i took to test the framerates.

Hi!

Thanks for your answer.

I think it's because I'm doing those loops on each Draw call instead of just doing it once and saving it to a costum class so i only have to call it through one loop.

But instead of that i'll do it like the tutorial (http://www.sfml-dev.org/tutorials/2.0/graphics-vertex-array.php) showed.

I think it will perform much better.

Thanks!

Hello!

I have a Tilemap that is 5 by 5 big and has 64 by 64 big Tiles!

I'm using .tmx maps with tmxparser lib and i have only 2 FPS.

Also at when the map ends there are still buggy grass tiles. What's the problem there? . Btw that's the only thing I'm rendering right now.

void DrawMap(){
        IntRect cropRect;
        for (int i = 0; i < testmap->map.layerCollection.size(); ++i)
        {
                tmxparser::TmxLayer layer = testmap->map.layerCollection[i];
                int currTile = 0;
                for (int y = 0; y < layer.width; y++)
                {
                        for (int x = 0; x < layer.height; x++)
                        {
                                if (layer.tiles[currTile].gid > 0){
                                        tmxparser::TmxTileset currTileset = testmap->map.tilesetCollection[layer.tiles[currTile].tilesetIndex];

                                       
                                        int tileIndex = layer.tiles[currTile].gid - currTileset.firstgid;
                                        cropRect.left = (tileIndex % (currTileset.image.width / 64)) * 64;
                                        cropRect.top = (tileIndex / (currTileset.image.width / 64)) * 64;
                                        cropRect.width = currTileset.tileWidth;
                                        cropRect.height = currTileset.tileHeight;

               
                                        VertexArray v(sf::Quads,4);
                                        v[0].position = Vector2f(x * 64, y * 64);
                                        v[1].position = Vector2f((x + 64) * 64, y * 64);
                                        v[2].position = Vector2f((x + 64) * 64, (y + 64) * 64);
                                        v[3].position = Vector2f(x * 64, (y + 64) * 64);

                                        v[0].texCoords = Vector2f(cropRect.left * 64, cropRect.top * 64);
                                        v[1].texCoords = Vector2f((64 + cropRect.left) * 64, cropRect.top * 64);
                                        v[2].texCoords = Vector2f((64 + cropRect.left) * 64, (64 + cropRect.top) * 64);
                                        v[3].texCoords = Vector2f(cropRect.left * 64, (64 + cropRect.top) * 64);

                                        window->draw(v, &currTileset.image.texture);
                                       
                                }
                                currTile++;
                                printf("Tile %i \n", currTile);
                        }

                }
                currTile = 0;
        }
}

Please help
