字符生成图片的方式在MonoGame或XNA中使用中文
MonoGame，XNA以及FNA在使用中文时比较麻烦，在之前我写过两种方式：
1.资源文件方式使用中文：https://www.xnadevelop.com/ios/use-chinese-in-monogame/
2.预编译xnb方式使用中文：https://www.xnadevelop.com/ios/monogame-character-support-simplification-tool/
下面介绍另一种方式：任意字符生成图片的方式使用中文
注意：本方法使用可在windows下运行
定义Texture2D来存储字符生成的图片
|
1 |
Texture2D textTexture2D; |
引用 System.Drawing.dll
在【LoadContent()】方法中将中文字符转换成Texture2D
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
string str = "使用monogame开发跨平台游戏"; Graphics g = Graphics.FromImage(new Bitmap(1, 1)); Font font = new Font("宋体", 20); SizeF sizeF = g.MeasureString(str, font); //测量出字体的高度和宽度 Brush brush; //笔刷，颜色 brush = Brushes.Lime; PointF pf = new PointF(0, 0); Bitmap img = new Bitmap(Convert.ToInt32(sizeF.Width), Convert.ToInt32(sizeF.Height)); g = Graphics.FromImage(img); g.DrawString(str, font, brush, pf); //将字符转换成Texture2D MemoryStream ms = new MemoryStream(); img.Save(ms, System.Drawing.Imaging.ImageFormat.Png); textTexture2D=Texture2D.FromStream(graphics.GraphicsDevice, ms); |
在【 Draw(GameTime gameTime)】方法中绘制
|
1 2 3 4 5 |
spriteBatch.Begin(); spriteBatch.Draw(textTexture2D, Vector2.Zero, Microsoft.Xna.Framework.Color.White); spriteBatch.End(); |
完整代码如下：
