Back to steve_ancell's Blog ( Created 22 August 2009 | Last Edited 22 August 2009) Development Ideas : Playing with XNA again. It seems apparent that XNA has no native Rect command, so I thought I would have a go at coding one myself. protected void Rect(GraphicsDevice g, SpriteBatch s, int x, int y, int w, int h, Color c, bool filled) { if (w < 1) return; if (h < 1) return; Vector2 pos = new Vector2(x, y); Texture2D texture = new Texture2D(g, w, h); Color[] color = new Color[texture.Width * texture.Height]; for (int across = 0; across <= 0 + (w - 1); across ++) { color[across] = c; } for (int across = 0; across <= 0 + (w - 1); across ++) { color[across + w * (h - 1)] = c; } for (int down = 0; down <= 0 + (h - 1); down ++) { color[down * w] = c; } for (int down = 0; down <= 0 + (h - 1); down ++) { color[(down * w) + (w - 1)] = c; } if (filled == true) { int i = 0; for (int down = 0; down <= (h - 1); down++) { for (int across = 0; across <= (w - 1); across++) { color[i] = c; i++; } } } texture.SetData(color); s.Draw(texture, pos, Color.White); } --> Usage would be something like... // Replace true with false, if you don't want the rectangle to be filled. spriteBatch.Begin(); Rect(graphics.GraphicsDevice, spriteBatch, 400, 300, 100, 50, Color.Red, true); spriteBatch.End(); --> Latest Comments Posted : Saturday, 22 August 2009, 14:52 Afr0 Oooh, kinda cool! Posted : Saturday, 22 August 2009, 14:55 steve_ancell Cheers Afr0 . I'm planning on coding an equivalent to the Blitz command Oval next. Posted : Saturday, 22 August 2009, 14:57 steve_ancell I also forgot to mention that I made this code as public domain, so use it as you wish Posted : Saturday, 22 August 2009, 15:21 steve_ancell There is one bug that I need to solve. The rectangle will not render if the (x, y) is less then (0, 0). But it may still come in handy for making grids ! Posted : Saturday, 22 August 2009, 16:09 steve_ancell Bug now fixed !
