[1.7.10] Rendering Item Icon on side of blocks

[EmperorZelos]

Hello! I am currently trying to make a block that shows the item content within it. I know how to get the item and all so that's not an issue. My issue is when it comes to rendering, I just cannot figure out a manner at which I grab the rendered icon for an item in inventory and render it on Tessellator. I have gotten a tessellator running but the issue is getting the texture.

 

How would I do this for a given item or stack?

 

Best regards and thanks in advance.

[EmperorZelos]

does that include ALL items, including those added by mods?

 

Edit:

It seems to work for that so thank you, but what about the icon of blocks? As they are rendered in inventories

When I use blocks I get it trying to render items that is somewhere along and it doesn't seem to fit.

 

ItemStack stack = new ItemStack(Item.getItemFromBlock(Blocks.brick_block), 1, 0);
drawIcon(0,0,stack.getIconIndex(),ForgeDirection.SOUTH);

private void drawIcon(int posX, int posY, IIcon icon, ForgeDirection side){
	Tessellator t = Tessellator.instance;
	float minU = icon.getMinU();
	float minV = icon.getMinV();
	float maxU = icon.getMaxU();
	float maxV = icon.getMaxV();
	int sizeX = 16;
	int sizeY = 16;
	GL11.glTranslated(posX, posY, 0.0D);
	//GL11.glBindTexture(TextureMap.locationItemsTexture);
	Minecraft.getMinecraft().renderEngine.bindTexture(TextureMap.locationItemsTexture);
	//GL11.glEnable(GL11.GL_BLEND);
	t.startDrawingQuads();
	t.addVertexWithUV(0, 0, 0, minU, maxV); //Bottom left texture
	t.addVertexWithUV(0, 1, 0, maxU, maxV); //Top left
	t.addVertexWithUV(1, 1, 0, maxU, minV); //Top right
	t.addVertexWithUV(1, 0, 0, minU, minV); //Bottom right

	/*t.addVertexWithUV(posX, posY+sizeY, 0D, minU, maxV);
	t.addVertexWithUV(posX + sizeX, posY + sizeY, 1D, maxU, maxV);
	t.addVertexWithUV(posX + sizeX, posY + 0, 1D, maxU, minV);
	t.addVertexWithUV(posX + 0, posY + 0, 0.0D, minU, minV);*/
	t.draw();
}

While that does certainly give me the texture of the block, it unfortunately does not give me the icon of the block one sees in the inventory. I mean the 3D rendition in the inventory one see of blocks, like for hte anvil and such.

[EmperorZelos]

I have looked into that one but I am uncertain how to render it on a Tessellator

[EmperorZelos]

What is ISBRH?

[EmperorZelos]

Ah I found it, I use TileEntitySpecialRenderer

[EmperorZelos]

Which I have dangerously low experience with unfortunately, do you know any guide that can make this work where I can get the icon and all rendered and shown? If I got that far I could play around and learn it.

Using it I can render the item but it seems to want to do a 3D model of it in the world =/ Which is not what I want sadly

The thing you see in your inventory is a 3D model of it in the world, seen from a diagonal, orthographic,  viewpoint.

You are unlikely to get this representation as a flat texture to draw on the face of a block. Which is why barrel mods draw a 3D block sticking out.
