title: Alpha animation for BitmapFont
body: <p>I am new to libgdx and want to know if there is an easy way to alpha animate a BitmapFont I am currently using <code>FreeTypeFont</code> to generate my font style and if I call:</p>
  
  <p><code>bitmapfont.setColor(1,1,1,alphahere)</code> </p>
  
  <p>then it would render my text back to normal removing the style from my FreeTypeFont.</p>
  
  <p>How can I animate the bitmap font with out removing its style from the FreeType?</p>
