What this line actually does?

Is there any difference haveing those icon.getMaxU() etc or having numbers? And why?

Need code line explain please.

Thanks

 

ItemRenderer.renderItemIn2D(Tessellator.instance, icon.getMaxU(), icon.getMinV(), icon.getMinU(), icon.getMaxV(), icon.getIconWidth(), icon.getIconHeight(), 16F / 256F);

Item and block textures are icons, because they are stitched onto a spritesheet at startup, reducing the required memory for texture storage. The Tessellator class uses U and V coordinates to render a texture. The U and V usually translate to the X and Y coordinates of the item texture on the spritesheet. If you are rendering a texture directly with Minecraft.renderEngine.bind(ResourceLocation), the U and V is usually 0 and 1, with 0 being, well 0, and 1 being the width/height of the texture. So the item's U and V is usually between those 2 numbers.

 

If you are using ItemRenderer, you don't need to worry about these methods. You only need to know about them if you are using the Tessellator directly.

 

It's the same as the glTexCoords2() in OpenGL (which Minecraft uses for rendering)

Thank for responce.

So in this line these function do not actually make a difference in the final result heh?
