I'm trying to render custom block which uses metadata for binding textures but my Minecraft crashes. Im trying to fix this for 4 hours straight now. Simple problem which you will probably notice in 1 min and I'm working on it for 4 hours without results.

ItemRenderer

 

public class ItemRendererTable implements IItemRenderer{
public boolean handleRenderType(ItemStack item, ItemRenderType type) {
  return true;
}
public boolean shouldUseRenderHelper(ItemRenderType type, ItemStack item, ItemRendererHelper helper) {
  return true;
}
public void renderItem(ItemRenderType type, ItemStack item, Object... data) {
  TileEntityRenderer.instance.renderTileEntityAt(new TileEntityTable(), 0.D, -0.2D, 0.0D, 0.0F);
}
}

 

 

Renderer:

 

public class RendererTable extends TileEntitySpecialRenderer{
    ResourceLocation texture1 = (new ResourceLocation("textures/woodworks/textures/models/tablemodel_oak.png"));
    ResourceLocation texture2 = (new ResourceLocation("textures/woodworks/textures/models/tablemodel_spruce.png"));
    ResourceLocation texture3 = (new ResourceLocation("textures/woodworks/textures/models/tablemodel_birch.png"));
    ResourceLocation texture4 = (new ResourceLocation("textures/woodworks/textures/models/tablemodel_jungle.png"));
Object blockTable = WoodworksCommonProxy.blockTable;
   
private ModelTable model;

public RendererTable(){
  this.model = new ModelTable();
}

public void renderTileEntityAt(TileEntity tileentity, double x, double y,double z, float f) {
  GL11.glPushMatrix();
  GL11.glTranslatef((float)x + 0.5F, (float)y + 1.5F, (float)z +0.5F);
  GL11.glRotatef(180, 0F, 0F, 1F);
  if(tileentity.getBlockMetadata() == 0){
      this.bindTexture(texture1);}
     
      if(tileentity.getBlockMetadata() == 1){
       this.bindTexture(texture2);}
      
       if(tileentity.getBlockMetadata() == 2){
        this.bindTexture(texture3);}
       
        if(tileentity.getBlockMetadata() == 3){
         this.bindTexture(texture4);}
  GL11.glPushMatrix();
  model.renderModel(0.0625F);
  GL11.glPopMatrix();
  GL11.glPopMatrix();
}

}

 

 

From what I was able to read from the crashreport I noticed that if I change this code:

  if(tileentity.getBlockMetadata() == 0){
      this.bindTexture(texture1);}
    
      if(tileentity.getBlockMetadata() == 1){
       this.bindTexture(texture2);}
     
       if(tileentity.getBlockMetadata() == 2){
        this.bindTexture(texture3);}
      
        if(tileentity.getBlockMetadata() == 3){
         this.bindTexture(texture4);}

to this code:

this.bindTexture(texture1);

everything works fine and every block metadata in Inventory has texture1. But I need all of them to work. Anyone can help me with this problem?

Well, if you're creating a new TileEntityTable() to render in your hand (ItemRenderer line 9) then it's not going to have a blook to request metadata from.

Ohhh I see. How can I make it request metadata from my block?

You would need to poll the itemstack.

Can you please provide me some open source codes or give me an example, never heard of this thing, I started modding forge 4 days ago.

When given lemons, make lemonade! And with that try searching the web for Combustible Lemon Launcher and git-hub and see what you find.  It's a fun mod that is open source. I've found it very useful to see how to do a number of things.
