有一种简单的方法来对齐文本的权利和中心(而不是默认的左)?
Answer 1:
第一步是测量使用串SpriteFont.MeasureString()
然后,例如,如果你想把它画到某个点的左边,而不是位于右侧是默认的,那么你就需要从文本绘制原点减去测量的X宽度。 如果你希望它为中心,那么你可以使用一半的测量等。
Answer 2:
我用这个代码:
[Flags]
public enum Alignment { Center=0, Left=1, Right=2, Top=4, Bottom = 8 }
public void DrawString(SpriteFont font, string text, Rectangle bounds, Alignment align, Color color )
{
Vector2 size = font.MeasureString( text );
Vector2 pos = bounds.GetCenter( );
Vector2 origin = size*0.5f;
if ( align.HasFlag( Alignment.Left ) )
origin.X += bounds.Width/2 - size.X/2;
if ( align.HasFlag( Alignment.Right ) )
origin.X -= bounds.Width/2 - size.X/2;
if ( align.HasFlag( Alignment.Top ) )
origin.Y += bounds.Height/2 - size.Y/2;
if ( align.HasFlag( Alignment.Bottom ) )
origin.Y -= bounds.Height/2 - size.Y/2;
DrawString( font, text, pos, color, 0, origin, 1, SpriteEffects.None, 0 );
}
Answer 3:
SpriteFont mFont;
SpriteBatch mSprite;
mSprite.Begin();
mSprite.DrawString(mFont, "YourText", new Vector2(graphicsDevice.Viewport.Width / 2 - mFont.MeasureString("YourText").Length() / 2, 0), Color.White, 0, new Vector2(0, 0), 1f, SpriteEffects.None, 0f);
mSprite.End();
