[1.8]Rendering with the Tessellator


Toxicshadow

Recommended Posts

Hey everyone,

Lately I've been working with the Tessellator, and it's almost nice. It seems that most people who use it, use it for blocks or for GUIs, however I'm not using it for either.

Instead I'm trying to render a box above entity heads. So far this is going okay, except it obviously doesn't rotate because I haven't set the vertices to update with the client. The actual code for the vertices is just:

// tw is just a worldrenderer from a tessellator object.
tw.addVertex(0,2,0);
tw.addVertex(0,3,0);
tw.addVertex(1,3,0);
tw.addVertex(1,2,0);

 

Like I said this works fine, but I am lost as to how to get this to rotate with the client. So I did some searching in the vanilla code and it looks like they handle it slightly differently. Their code for rotation is:

 

GlStateManager.rotate(-this.renderManager.playerViewY, 0.0F, 1.0F, 0.0F);
GlStateManager.rotate(this.renderManager.playerViewX, 1.0F, 0.0F, 0.0F);

 

Because I'm using Tessellator and not a GlStateManager, I'm not sure how to go about this.

 

Any help would be appreciated!

Then just use GlStateManager to rotate it.

In my attempt to use the GlStateManager I gave the player a permanent superman-pose disability.

 

While I won't ask for a tutorial on using GlStateManager, how do you access the statemanager for a Tessellator and a WorldRenderer object? The vanilla code on this doesn't make much sense to me...

You don't have to, and should not access the WorldRenderer object..

 

You need to put this before rendering yours:

GlStateManager.pushMatrix();

 

and this after yours:

GlStateManager.popMatrix();
