Hey, How can I render a Quad in the world and apply an TextureAtlasSprite to it?

I tried:

GL11.glBegin(GL11.GL_QUADS);
GL11.glColor3f(1.0f, 1.0f, 1.0f);
        GL11.glVertex3d(x, y, z);
        GL11.glVertex3d(x + 1, y, z);
        GL11.glVertex3d(x + 1, y + 1, z);
        GL11.glVertex3d(x, y + 1, z);
        GL11.glEnd();

 

But it isnt working... Please help me I think i cant use the default openGL functions

Tessellator tessellator = Tessellator.getInstance();

WorldRenderer renderer = Tessellator.getInstance().getWorldRenderer();

renderer.begin(GL11.GL_QUADS, DefaultVertexFormats.BLOCK); // The default vertex format depends on your use case, experiment.

For every vertex:

 

worldrenderer.pos(x,y,z) // If you have u,v you have to add some additional stuff

 

tessellator.draw()

 

 

As of 1.9 WorldRenderer is VertexBuffer.

Lookup Gui.class for use examples of vertex format.

 

render a Quad in the world

 

You know, just adding and drawing vertexes will place them "who knows where". What is your translation/scale context? What event or other rendering are you using?
