[1.7] Render custom block as item in inventory

[Jhary]

*sigh* Hi again !

 

As solved in this topic : http://www.minecraftforge.net/forum/index.php/topic,20137.0.html

my custom rendered block now does everything I want, but .. it does not render as an item in my hand or in my inventory.

I just get a flat not found texture (the black/purple thingy)

 

My ISimpleBlockRenderingHelper implementation hast got this method here that seems what I have to use:

 

@Override
public void renderInventoryBlock(Block block, int metadata, int modelID, RenderBlocks renderer) {

}

 

But how do I use it correctly? There is a method from the RenderBlocks class called .renderBlockAsItem(Block block, int noclue, float noclue).

But just using this method and testing with the values did not change a single thing.

I even tried defining each IIcon to render on every side using the methods from the RenderBlocks class (.renderFace*) and then calling the .renderBlockAsItem

method but that didn't work either..

 

On http://greyminecraftcoder.blogspot.com.au/ there is an article about rendering custom blocks in inventories but I don't really get it this time.

For reference, here is my custom renderer implementation :

 

public class MyTileRenderer implements ISimpleBlockRenderingHandler{

  @Override
  public void renderInventoryBlock(Block block, int metadata, int modelID, RenderBlocks renderer) { 
  
  }

  @Override
   public boolean renderWorldBlock(IBlockAccess world, int x, int y, int z, Block block, int modelId, RenderBlocks renderer) {

    	IIcon top = block.getIcon(world, x, y, z, 1);
    	IIcon bottom = block.getIcon(world, x, y, z, 0);
    	IIcon north = block.getIcon(world, x, y, z, 2);
    	IIcon south = block.getIcon(world, x, y, z, 3);
    	IIcon west = block.getIcon(world, x, y, z, 4);
    	IIcon east = block.getIcon(world, x, y, z, 5);
    	
    	renderer.renderFaceXNeg(block, x, y, z, west);
    	renderer.renderFaceXPos(block, x, y, z, east);
    	renderer.renderFaceYNeg(block, x, y, z, bottom);
    	renderer.renderFaceYPos(block, x, y, z, top);
    	renderer.renderFaceZNeg(block, x, y, z, north);
    	renderer.renderFaceZPos(block, x, y, z, south);
    	
    	TileEntity tile = world.getTileEntity(x, y, z);
    	if(tile instanceof TileEntityMyTile){
    		//wonky rendering incoming
    		switch(((TileEntityMyTile)tile).orientation.ordinal()){
    			case 0: //Bottom
    				renderer.uvRotateNorth=2; //west
    				renderer.uvRotateSouth=1; //east
    				renderer.uvRotateWest=2; //south
    				renderer.uvRotateEast=1; //north
    				break;
    			case 1: //Top
    				renderer.uvRotateNorth=1;
    				renderer.uvRotateSouth=2;
    				renderer.uvRotateWest=1;
    				renderer.uvRotateEast=2;
    				break;				
    			case 2: //North
    				renderer.uvRotateTop = 1;
    				renderer.uvRotateBottom = 2;
    				
    				break;
    			case 3: //South
    				renderer.uvRotateTop=2;
    				renderer.uvRotateBottom=1;
    				renderer.uvRotateNorth=3; 
    				renderer.flipTexture=true; //east
    				break;
    			case 4: //West
    				renderer.uvRotateTop=4;
    				renderer.uvRotateBottom=4;
    				break;
    			case 5: //East
    				renderer.uvRotateTop=3;
    				renderer.uvRotateBottom=3;
    				renderer.flipTexture=true;
    				break;
    		}
    	}
    	
    	boolean flag = renderer.renderStandardBlock(block, x, y, z);
    	//important reset afterwards!
    	renderer.flipTexture=false; 
    	renderer.uvRotateNorth=0; //west
renderer.uvRotateSouth=0; //east
renderer.uvRotateWest=0; //south
renderer.uvRotateEast=0; //north
renderer.uvRotateTop=0;
renderer.uvRotateBottom=0;
return flag;
  }

  @Override
   public int getRenderId() {
    	return ClientProxy.myTileRenderID;
   }

  @Override
  public boolean shouldRender3DInInventory(int modelId) {
return false;
  }

}

[Kwibble]

You have shouldRender3DInInventory set to false. No wonder nothing seemed to be happening

[Jhary]

Yeah its turned off, right. But if I turn it on, the only difference is that it is just invisible in my inventory/hand.

You are right, it should be set to true, but that does not solve the rendering because I still don't really know what to do in the

renderInventoryBlock(...) method of my ISimpleBlockRenderingHandler..

 

Here is what I tried:

 

   @Override
    public void renderInventoryBlock(Block block, int metadata, int modelID, RenderBlocks renderer) {
        IIcon top = renderer.getBlockIconFromSide(block, 1);
    	IIcon bottom = renderer.getBlockIconFromSide(block, 0);
    	IIcon north = renderer.getBlockIconFromSide(block, 2);
    	IIcon south = renderer.getBlockIconFromSide(block, 3);
    	IIcon west = renderer.getBlockIconFromSide(block, 4);
    	IIcon east = renderer.getBlockIconFromSide(block, 5);
    	
    	renderer.renderFaceXNeg(block, 0, 0, 0, west);
    	renderer.renderFaceXPos(block, 0, 0, 0, east);
    	renderer.renderFaceYNeg(block, 0, 0, 0, bottom);
    	renderer.renderFaceYPos(block, 0, 0, 0, top);
    	renderer.renderFaceZNeg(block, 0, 0, 0, north);
    	renderer.renderFaceZPos(block, 0, 0, 0, south);
    	
    }

 

renderer.renderFace* needs coordinates that I don't got here. And if I use

 

renderer.renderBlockAsItem(block, 3, 1.0F);

 

instead I just get a Stack Overflow Exception..

 

I am a bit clueless at the moment..

[Kwibble]

Tessallator mate go to the forge wiki, and search it up. Specifically the one by hydroflame (there is only one part that is outdated. Instead of the texture binding he uses, use:

 minecraftInstance.getTextureManager().bindTexture(resourcelocation);

)

 

See if that works.

Hi

 

For renderFace use the coordinates from [0,0,0] to [1,1,1] because the caller has already set those coordinates for you.  In 1.6.4 you needed to do an extra translate, that may have changed, but it will be obvious if so.

 

The vanilla code is in RenderBlocks.renderBlockAsItem(), so for example this code from 1.6.4

                    GL11.glTranslatef(-0.5F, -0.5F, -0.5F);
                    tessellator.startDrawingQuads();
                    tessellator.setNormal(0.0F, -1.0F, 0.0F);
                    this.renderFaceYNeg(par1Block, 0.0D, 0.0D, 0.0D, this.getBlockIconFromSide(par1Block, 0));
                    tessellator.draw();
                    tessellator.startDrawingQuads();
                    tessellator.setNormal(0.0F, 1.0F, 0.0F);
                    this.renderFaceYPos(par1Block, 0.0D, 0.0D, 0.0D, this.getBlockIconFromSide(par1Block, 1));
                    tessellator.draw();
                    tessellator.startDrawingQuads();
                    tessellator.setNormal(0.0F, 0.0F, -1.0F);
                    this.renderFaceZNeg(par1Block, 0.0D, 0.0D, 0.0D, this.getBlockIconFromSide(par1Block, 2));
                    tessellator.draw();
                    tessellator.startDrawingQuads();
                    tessellator.setNormal(0.0F, 0.0F, 1.0F);
                    this.renderFaceZPos(par1Block, 0.0D, 0.0D, 0.0D, this.getBlockIconFromSide(par1Block, 3));
                    tessellator.draw();
                    tessellator.startDrawingQuads();
                    tessellator.setNormal(-1.0F, 0.0F, 0.0F);
                    this.renderFaceXNeg(par1Block, 0.0D, 0.0D, 0.0D, this.getBlockIconFromSide(par1Block, 4));
                    tessellator.draw();
                    tessellator.startDrawingQuads();
                    tessellator.setNormal(1.0F, 0.0F, 0.0F);
                    this.renderFaceXPos(par1Block, 0.0D, 0.0D, 0.0D, this.getBlockIconFromSide(par1Block, 5));
                    tessellator.draw();
                    GL11.glTranslatef(0.5F, 0.5F, 0.5F);

 

Don't call renderBlockAsItem, because that's what called your renderer in the first place.  i.e. you wind up in an infinite loop ("recursion") until the stack overflows.

This implementation seems to work. I got a 3D block now in my inventory

But.. no valid textures. Maybe the renderer.getBlockIconFromSide(..) seems to find no IIcon..strange.

 

renderer.getBlockIconFromSideAndMetadata(..) has no effect, too.

[TheGreyGhost]

Hi.

 

If your textures are invalid, look in your error log.

 

This link might help.

No you get me wrong. The textures are fine. The block renders if placed correctly with all the textures. Just like I want it.

I just don't get it to work in my inventory / hand.

 

I just get a 3D block with the purple/black texture...

 

@Override
public void renderInventoryBlock(Block block, int metadata, int modelID, RenderBlocks renderer) {

Tessellator tessellator = Tessellator.instance;

block.setBlockBoundsForItemRender();
GL11.glTranslatef(-0.5F, -0.5F, -0.5F);
        tessellator.startDrawingQuads();
        tessellator.setNormal(0.0F, -1.0F, 0.0F);
        renderer.renderFaceYNeg(block, 0.0D, 0.0D, 0.0D, renderer.getBlockIconFromSide(block, 0));
        tessellator.draw();
        tessellator.startDrawingQuads();
        tessellator.setNormal(0.0F, 1.0F, 0.0F);
        renderer.renderFaceYPos(block, 0.0D, 0.0D, 0.0D, renderer.getBlockIconFromSide(block, 1));
        tessellator.draw();
        tessellator.startDrawingQuads();
        tessellator.setNormal(0.0F, 0.0F, -1.0F);
        renderer.renderFaceZNeg(block, 0.0D, 0.0D, 0.0D, renderer.getBlockIconFromSide(block, 2));
        tessellator.draw();
        tessellator.startDrawingQuads();
        tessellator.setNormal(0.0F, 0.0F, 1.0F);
        renderer.renderFaceZPos(block, 0.0D, 0.0D, 0.0D, renderer.getBlockIconFromSide(block, 3));
        tessellator.draw();
        tessellator.startDrawingQuads();
        tessellator.setNormal(-1.0F, 0.0F, 0.0F);
        renderer.renderFaceXNeg(block, 0.0D, 0.0D, 0.0D, renderer.getBlockIconFromSide(block, 4));
        tessellator.draw();
        tessellator.startDrawingQuads();
        tessellator.setNormal(1.0F, 0.0F, 0.0F);
        renderer.renderFaceXPos(block, 0.0D, 0.0D, 0.0D, renderer.getBlockIconFromSide(block, 5));
        tessellator.draw();
        GL11.glTranslatef(0.5F, 0.5F, 0.5F);
}

 

The error log shows not a single error..

[Kwibble]

Like I said... bind textures via

minecraftInstance.getTextureManager().bindTexture(resourcelocation);

[Jhary]

Yeah I already tried that, if I bin my textures beforehand like this :

 

Minecraft.getMinecraft().getTextureManager().bindTexture(new ResourceLocation("mymod:block_front"));

Minecraft.getMinecraft().getTextureManager().bindTexture(new ResourceLocation("mymod:block_top"));

Minecraft.getMinecraft().getTextureManager().bindTexture(new ResourceLocation("mymod:block_side"));

Minecraft.getMinecraft().getTextureManager().bindTexture(new ResourceLocation("mymod:block_back"));

 

But then the 3D block renders very dark and I cannot see if it is just black or my textures..

 

I tried to setup the lighting of my tessellator with tessellator.setBrightness(int) but I can't figure out how to get the brightness value.

 

block.getMixedBrightnessForBlock(...) needs a world and coordinates that I don't have in this method.

[Kwibble]

Bind one texture at a time as you need it... Not all at once. (that is what I got from that)

 

Also, it's:

new ResourceLocation("modid", "textures/blocks/block_front.png")

 

That could well solve your problem.

[Jhary]

I did now bind one texture at a time as I needed it But.. nothing gets better. Probably it is more of a lighting problem and if I get that sorted out I see the textures.(Now its just dark .. perhaps the textures are therer but without lighting?)

 

But as I said above:

 

I tried to setup the lighting of my tessellator with tessellator.setBrightness(int) but I can't figure out how to get the brightness value.

 

block.getMixedBrightnessForBlock(...) needs a world and coordinates that I don't have in this method.

[Kwibble]

You could always use GL11.glDisable(GL11.GL_LIGHTING); before your drawing and GL11.glEnable(GL11.GL_LIGHTING); after. This would help you figure out if your textures are there or not.

[Jhary]

hmm ok it was not the lighting. I get just a 3D block completely covered in dark grey. Not as in too dark, as in here:

 

http://www.directupload.net/file/d/3658/ondfi9un_png.htm

 

The texture binding seems to work correctly because if I remove the .png file extension for testing I get an exception on startup.

 

I disable the GL11 lighting at the beginning of my method and enable it again at the end. That is right? Or do I have to do that before and after every single

 

Minecraft.getMinecraft().getTextureManager().bindTexture(new ResourceLocation("modid","textures/blocks/filename.png"));
tessellator.startDrawingQuads();
tessellator.setNormal(0.0F, 0.0F, 1.0F);
renderer.renderFaceZPos(block, 0.0D, 0.0D, 0.0D, renderer.getBlockIconFromSide(block, 3));
tessellator.draw();

 

code block?

(the parameters of the Resource Location constructor are different in my case)
