I want to make an energy meter where you can read the data without opening a GUI. I tried it with the FontRenderer but I can't use it because it only has x and y coordinates and I need a z coordinate too. I didn't really try using the tesselator because I have problems understanding that thing. Is there any other way of doing this?

You can draw string onto tess-drawn box in x/y/z.

 

For real examples you could look how entity names are rendered above head.

Ok, is it also possible to do that without a tesselator?

I don't think there is any easier/nicer way to do it. You most certainly want to use FontRenderer and to do that you need something to draw on - plane.

 

GL11.glTranslatef((float) (x - Minecraft#getRenderManager().viewerPosX), (float) (y - Minecraft#getRenderManager().viewerPosYt), (float) (z - Minecraft#getRenderManager().viewerPosZ));

That's how you get x/y/z.

You need few rotations and little translation to fit your plane (block walls) and draw using:

Tessellator tess = Tessellator.getInstance();
WorldRenderer wr = tess.getWorldRenderer();
wr.addVertex ... and next, and next, and next.

and then draw sting with FontRenderer.

 

 

 

I have a model which extends ModelBase, is it possible to put text ob one of the plane boxes from the model?
