1.8.9 trying to understand ISmartItemModel[solved]

[UberAffe]

I've been looking at examples and reading any tutorials I can find but it's just not clicking for me.

 

I am trying to generate an ItemModel from nbt. I have a set of parts, each part has information about its location(relative to a 16x16x16 cube), it's RGBA and eventually its quad once I figure out how this works. I am trying to stitch this information together to create the model.

 

I am unsure what other information would be need to for someone to actually help, so I will either provide whatever people ask for or do my best implement what I am missing and then bring it back here.

ISmartItemModel is just a way to let the model decide an alternate model based on the ItemStack being rendered. handleItemState is being called with an ItemStack so that the Model can determine which model to actually render for that specific stack (based on NBT or whatever you want, really).

Usually ISmartItemModel (or other special baked models) are registered using ModelBakeEvent, where you can bind an actual baked model to a ModelResourceLocation.

 

For your usecase (generating models dynamically) you would have to have some sort of cache inside the ISmartItemModel so that you do not have to regenerate the models every frame. How to generate the models depends on how they should look exactly.

Ok, so right now I have a registry of all available Draftable items that gets maintained server side and a client side registry that gets updated by the server. So I will probably want to generate my model for each Draftable when it gets updated from the server.

 

public DraftableSmartItemModel implements ISmartItemModel{

   @Override
   public IFlexibleBakedModel handleItemState(ItemStack stack) {
      IFlexibleBakedModel model = null;
      if(stack.getTagCompound().hasKey(Refs.DRAFTABLE) && stack.model == null)
         model = DraftableReg.GetModel(stack.getTagCompound().getString(Refs.DRAFTABLE));
      return model;
   }

}

 

I assume that this is not unique per ItemStack, meaning that I would have to do it this way and not have model as a private class variable.

 

Next part:

From what I can tell I will still need to used BakedQuads for my model. So I looked into BakedQuads and FaceBakery for the vertex information, but what is happing with shadecolor and is this where I would store my RGBA information?

This is what is getting stored in shade color from FaceBakery, which appears to be a range of magenta - blue but I really don't know what is going on in that return. I recognize the shift left but thats it.

private int getFaceShadeColor(EnumFacing facing)
    {
        float f = this.getFaceBrightness(facing);
        int i = MathHelper.clamp_int((int)(f * 255.0F), 0, 255);
        return -16777216 | i << 16 | i << 8 | i;
    }

The way you are doing your model there looks fine.

 

For the quad thingy, what exactly are you trying to achieve here now?

[UberAffe]

I am planning something like this:

DraftableBakedModel implements IFlexibleBakedModel{

   private List<BakedQuad> quads = new ArrayList<BakedQuad>();

   public DraftableBakedModel(IDraftable draft){
      HashMap<String, IPartType> parts = draft.getParts();
      for(int i = x; x < 16; x++)
         for(int y = 0; y < 16; y++)
            for(int z = 0; z < 16; z++)
               if(parts.contain(x + "," + y + "," z))
                  quads.addAll(getQuadFrom(parts.get(x + "," + y + "," z), x, y, z);

   }

   //x, y, z specify the relative top, left, front, for the part to base it's vertices from.
   private List<BakedQuad> getQuadFrom(IPartType part,int x, int y, int z){
      // part has relative vertex information and RGBA for the color and transparency
      // that this part should render with.
      // each part can be thought of as a semi transparent, single color cube
      // although they may not actually be cubes
   }
   
}

 

1. is this the correct place to be specifying a color to render with?

2. it seems like each vertex of Baked Quad only has 1 variable for color, so how do I store the color?

[diesieben07]

I must admit have not yet generated my own BakedQuads, so I cannot help you here.

[UberAffe]

Alright. Well now that I have boiled it down to generating a BakeQuad I might split that into a new question.

 

Thanks for the help up to now.
