You probably can't, since entity models rely on raw OpenGL instructions. You can probably render a regular baked model for the simple parts and then render the entity model from a 

TESR

. The enchanting table does something like this: the base is a baked model, the book is rendered from the 

TESR

.

Crap, one of my friends made an entity model for me using .json, does this mean I just can't use it? It'd really bum him out if I couldn't put it in the game

Oh, you have a JSON model that you want to render as an entity? I thought you had an entity model that you wanted to render as an item/block.

 

It's certainly possible to render baked models as entities, look at 

RenderFallingBlock

.

BlockRendererDispatcher blockrendererdispatcher = Minecraft.getMinecraft().getBlockRendererDispatcher();
                    IBakedModel ibakedmodel = blockrendererdispatcher.getModelFromBlockState(iblockstate, world, (BlockPos)null);
                    blockrendererdispatcher.getBlockModelRenderer().renderModel(world, ibakedmodel, iblockstate, blockpos, worldrenderer, false);

 

RenderFallingBlock requires for the model to already be on a block though. Making a new block for each piece of the model is an organization nightmare D:

 

I'm assuming that I can bypass most of the block requirements, but how do I get an IBakedModel from the .json?

Ah, it looks like it's a bit tricky to render a baked model that isn't a 

Block

or 

Item

(since Minecraft rarely uses baked models for other things).

 

You should be able to subscribe to 

ModelBakeEvent

, load the model into an 

IModel

using 

ModelLoader#getModel

, bake it using 

IModel#bake

(look at how this is used in 

ModelLoader#setupModelRegistry

) and then add it to the model registry with 

IRegistry#putObject

. The 

ModelLoader

and model registry are provided as fields of 

ModelBakeEvent

.

 

Look at 

RenderItemFrame#doRender

to see how you can render an 

IBakedModel

that doesn't belong to a 

Block

or 

Item

.

 

I'm far from an expert in the model/rendering system, so I can't guarantee that this is correct.

Alright, so I got the models loading and rendering, but the problem is the texture is missing.

 

I can apply any texture I want using renderManager.renderEngine.bindTexture(location); but I want it to use the texture described in the .json .

 

Here's the relevant code:

 

Model Baking Code:

IModel cannonBase = event.modelLoader.getModel(RenderCannon.cannonBase);
Function<ResourceLocation, TextureAtlasSprite> textureGetter = new Function<ResourceLocation, TextureAtlasSprite>(){
       public TextureAtlasSprite apply(ResourceLocation location){
              return Minecraft.getMinecraft().getTextureMapBlocks().getAtlasSprite(location.toString());
       }
}
RenderCannon.cannonBaseBaked = cannonBase.bake(cannonBase.getDefaultState(), DefaultVertexFormats.BLOCK, textureGetter);

 

Render Code:

BlockRendererDispatcher blockrendererdispatcher = Minecraft.getMinecraft().getBlockRendererDispatcher();
IBakedModel ibakedmodel = cannonBaseBaked;
renderManager.renderEngine.bindTexture(TextureMap.locationBlocksTexture);
blockrendererdispatcher.getBlockModelRenderer().renderModelBrightnessColor(ibakedmodel, 1.0F, 1.0F, 1.0F, 1.0F);

 

And the .json model, textures and all of it:

{
    "__comment": "Cannon model - bracket only (for animation)",
    "textures": {
        "particle": "blocks/Rusty shaft",
        "0": "blocks/wood_spruce",

Do you have missing texture errors in the log? Your model's texture paths don't have a resource prefix, so it's trying to load them from the 

minecraft

domain.

      updateShape functionality deep dive

      By Sandermall · Posted

      Hello all. I'm currently grappling with the updateShape method in a custom class extending Block.  My code currently looks like this: The conditionals in CheckState are there to switch blockstate properties, which is working fine, as it functions correctly every time in getStateForPlacement.  The problem I'm running into is that when I update a state, the blocks seem to call CheckState with the position of the block which was changed updated last.  If I build a wall I can see the same change propagate across. My question thus is this: is updateShape sending its return to the neighbouring block?  Is each block not independently executing the updateShape method, thus inserting its own current position?  The first statement appears to be true, and the second false (each block is not independently executing the method). I have tried to fix this by saving the block's own position to a variable myPos at inception, and then feeding this in as CheckState(myPos) but this causes a worse outcome, where all blocks take the update of the first modified block, rather than just their neighbour.  This raises more questions than it answers, obviously: how is a different instance's variable propagating here?  I also tried changing it so that CheckState did not take a BlockPos, but had myPos built into the body - same problem. I have previously looked at neighbourUpdate and onNeighbourUpdate, but could not find a way to get this to work at all.  One post on here about updatePostPlacement and other methods has proven itself long superceded.  All other sources on the net seem to be out of date. Many thanks in advance for any help you might offer me, it's been several days now of trying to get this work and several weeks of generally trying to get round this roadblock.  - Sandermall
