copied!<p>Not sure if this is the best way to deal with the problem, but I've started to use RenderTarget2D to pre-render chunks of the world into textures. I have to load chunks within a given area around the actual screen bounds at a time, because loading all chunks at once will make it run out of memory.</p> <p>When you get close to the bounds of the current pre-rendered area, it will re-process chunks based on your new position in the world. The processing takes roughly 100 milliseconds, so when loading new areas the player will feel a slight slowdown for this duration. I don't really like that, but at least the FPS is 60 now.</p> <p>Here's my chunk processor:</p> <pre><code> public bool ProcessChunk(int x, int y) { // Create render target using (RenderTarget2D target = new RenderTarget2D(Game.CurrentDevice, 16 * 48, 16 * 48, false, SurfaceFormat.Color, DepthFormat.Depth24)) { // Set render target Game.CurrentDevice.SetRenderTarget(target); // Clear back buffer Game.CurrentDevice.Clear(Color.Black * 0f); // Begin drawing Game.spriteBatch.Begin(SpriteSortMode.Texture, BlendState.AlphaBlend); // Get block coordinates int bx = x * 48, by = y * 48; // Draw blocks int count = 0; foreach (WorldSection section in Sections) { // Continue if section is out of chunk bounds if (section.X >= bx + 48) continue; // Draw all tiles within the screen range for (int ax = 0; ax < 48; ax++) for (int ay = 0; ay < 48; ay++) { // Get the block character char b = section.Blocks[ax + bx - section.X, ay + by]; // Draw the block unless it's an empty block if (b != '0') { Processor.Blocks[b.ToString()].DrawBlock(new Vector2(ax, ay), true); count++; } } } // End drawing Game.spriteBatch.End(); // Clear target target.GraphicsDevice.SetRenderTarget(null); // Set texture if (count > 0) { // Create texture Chunks[x, y] = new Texture2D(Game.CurrentDevice, target.Width, target.Height, true, target.Format); // Set data Color[] data = new Color[target.Width * target.Height]; target.GetData<Color>(data); Chunks[x, y].SetData<Color>(data); // Return true return true; } } // Return false return false; } </code></pre> <p>If there are any suggestions on how this approach can be improved, I won't be sad to hear them!</p> <p>Thanks for the help given here!</p>
