How to Render a PlayerName above a Block?


Busti

Recommended Posts

Hello,

is there any easy way to render a Text above a Block like the Text above the Player?

I'am trying to display some information above a Block when a Player clicks it with a special Item but only showing it in the chat seems a little bit boring  ;D

 

I'm looking forward to your Help

either get it from someone who already done this, copy over what vanilla minecraft is using or make a fontRenderer yourself from scratch.

 

i suggest you do not make 1 from scratch becuase its a pain to implements. though if you want i can share mine.

 

you will also need a TileEntitySpecialRenderer

basicly this, make sure you have the file "sf.png"  at the root of miencraft.jar (if you're in eclipse its the root of "moddirectory/jars/bin/minecraft.jar"  )

and to make a draw call (most likely from a TileEntitySpecialRenderer)

 

FontRendererFR.instance.drawString(message, startX, startY, heightOfTheLetter, isItFor3DOr2D, red, green, blue);

 

 

 

the image is here

is looks all white, but thats becasue the site doesnt accept alpha, if you zoom in enough youll see that theres is actually an alphabet there, and if you save the image itll be transparent
