[1.15.2] [Solved] Dynamically create Item model from dynamically generated item texture

Budschie · June 2, 2020

Hello. I've now implemented a custom tool crafting system (similar to Tinker's construct) with Modifiers etc.

Now I have to generate a texture out of the materials the tool is made of.

How can I do that?

Thanks for any help.

Look at the Map and the DynamicTexture class.

You could also @Jayzx535 for help, he has done some work with dynamic textures recently

@TheGreyGhost Thanks. I'll try it out.

Budschie · June 2, 2020

The map uses a custom render class. How can I attach a custom render class to an item?

TheGreyGhost · June 2, 2020

Howdy

Item.setISTER lets you use a TileEntityRenderer for rendering your item. You can take the rendering functionality from the map rendering class(es) and copy them into your own renderer.

Or you can add a custom model and do the same thing, i.e. copy the rendering functionality from the map rendering class(es)

(see eg mbe15 in https://github.com/TheGreyGhost/MinecraftByExample)

The basic idea is:

1) generate a custom dynamic texture

2) bind the texture

3) draw one or more quads

@TheGreyGhost Thanks for replying, but I can't find a static or non-static method in Item.java called "setISTER".

Ah, my bad. It's actually in Item.Properties nested class

Item.java:      

It's in the nested class Properties

public Item.Properties setISTER(java.util.function.Supplier<java.util.concurrent.Callable<net.minecraft.client.renderer.tileentity.ItemStackTileEntityRenderer>> ister) {
         this.ister = ister;
         return this;
      }

--> is Right at the very end of the class

-TGG

Budschie · June 2, 2020

I'm now attaching my custom item renderer to the item like this:

new CommonTool(new Item.Properties().setISTER(() -> new Callable<ItemStackTileEntityRenderer>()
	{
		DynamicCommonToolRendering r = null;
		
		@Override
		public ItemStackTileEntityRenderer call() throws Exception
		{
			if(r == null)
				r = new DynamicCommonToolRendering();
			
			return r;
		}
		
	}));

But it won't run the render method which is defined in DynamicCommonToolRendering().

What have I done wrong?

TheGreyGhost · June 3, 2020

Howdy

There could be lots of possible reasons for that. Probably your item model doesn't have "builtin/entity" as the parent type. (see the "Item" section of https://minecraft.gamepedia.com/Model)

If that doesn't work, I'd suggest trying some breakpoints in strategic locations, eg:

- inside your lambda for supplying the ItemStackTileEntityRenderer

- inside the render method of vanilla ItemStackTileEntityRenderer

- inside ItemRenderer::renderItem(ItemStack itemStackIn ....)

-TGG

Budschie · June 3, 2020

@TheGreyGhost Thanks. It works now. But I have a new problem:

I am doing something wrong while loading the images of the tool parts:

I'm currently using

DynamicTexture tex = new DynamicTexture(NativeImage.read(this.getClass().getResourceAsStream("assets/deepnether/textures/item/toolparts/" + stick.getImage(Part.STICK, toolType) + ".png")));

to load a texture, but the stream seems to be "null".

Budschie · June 3, 2020

Ok, I now fixed the issue I mentioned in the post above, but now I have the problem that the whole texture atlas is used as a texture for my item...

Budschie · June 4, 2020

I now fixed the issue that I mentioned above as well, but now I have another problem: The item doesn't look like a standard minecraft item (it's just a plane with a texture), and doesn't seem to be translated the right way when you hold it in your hands.

Is there any way to create an 3-dimensional model from a dynamic texture?

Yes, that's how generated item models work.

Budschie · June 4, 2020

But how can I generate an item mesh from a dynamic texture?

Is there any way to do it with vanilla code, or do I have to do it with my own code?

Edited June 4, 2020 by Budschie

Budschie · June 5, 2020

Well, I think I have to generate the custom item mesh myself. There is one question left I have:

Are minecraft block faces triangles or quads?

Budschie · June 5, 2020

Should I set the vertices directly, or should I use a ModelRenderer?

Budschie · June 5, 2020

I still have no solution, please help. I've tried to generate a model out of the texture, but I have no idea in which direction the normals should face etc.

Howdy

You have a couple of options;

if you just want to generate a flat "pizza box" model with your texture, you can use any of the methods in these example classes

https://github.com/TheGreyGhost/MinecraftByExample/blob/master/src/main/java/minecraftbyexample/mbe04_block_dynamic_block_models/AltimeterBakedModel.java

https://github.com/TheGreyGhost/MinecraftByExample/blob/master/src/main/java/minecraftbyexample/mbe21_tileentityrenderer/RenderQuads.java

or BlockModel::bakeVanilla

If you want to generate an item model with 'holes' in it, similar to vanillla, then look at ItemModelGenerator to see how vanilla does it or ItemLayerModel forge extension for further clues. Haven't done that myself....

@TheGreyGhost Thanks for responding.

I made this bit of code, but the face normals of the generated model are wrong, resulting in rendering issues:

How can I fix that?

Howdy

If your face normals are wrong, fix them? It should be pretty obvious how, based on the code that you posted?

@TheGreyGhost The problem is, that I have no idea what is going on. From one side, you can see a line, and from the other side of the face, you can see the tool.

Everything is clipping, etc., as you can see in this thread:

Ah ok, now I understand what you mean. That's nothing to do with the vertex normals information, it's because of back face culling.

Each quad has a direction - a front face and a back face. Usually, the back face is not drawn.

The direction that the face is pointing is determined by the order of the vertices.

If you are looking at the front of the face, the four vertices should be in anti-clockwise order.

So if the face is pointing the wrong way, you just need to reverse the order of your vertices.

For example: your left-right draws in the order of

maxY, minZ

maxY, maxZ

minY, maxZ

minY, minZ

which is clockwise

Instead, add the vertices in the opposite order, i.e.

minY, minZ

minY, maxZ

maxY, maxZ

maxY, minZ

@TheGreyGhost Thank you! This solved my problems.
