I'm having a tough time getting alpha transparency on strings to work.

 

         	GL11.glPushMatrix();
         	GL11.glEnable(GL11.GL_BLEND);
         	OpenGlHelper.glBlendFunc(770, 771, 1, 0);
         	mc.fontRenderer.drawStringWithShadow("Hello, world!", x, y, color + (alpha << 24));
         	GL11.glDisable(GL11.GL_BLEND);
         	GL11.glPopMatrix();

 

The alpha value is between 0 and 255, inclusively, but it refuses to render on certain numbers. Is there a different way of accomplishing this, or is my bitwise calculation off? I can't find help support for GUI text transparency anywhere.

 

Thanks in advance.

 

try a bitwise OR operation ( | operator)

 

e.g.

 

color | (alpha << 24)

 

Although for this use (with colors being bit-aligned), there should not be a functional difference.  Unfortunately, I have not tried playing around with transparent font-rendering, so could not give you a 100% for sure solution =\.

It works perfectly now! Thank you!!
