Forge: Models, Textures and their UVs

[mewewe8]

Where does Forge/Modded Minecraft define what model uses what Texture and in that Texture what coordinates?

In the "client.model.modelEntityX" all i can find is this.textureWidth, this.textureHeight. But that doesnt specify the UV.

 

So what im looking for is a way to do somthing like this

 

<model,renderer,entity whatever> .Add/SetTexture("textures/bla/mygoblin_top.png");

<model,renderer,entity whatever> .SetUvOfLastTexture(0,0,16,16);

<model,renderer,entity whatever> .Add/SetTexture("textures/bla/mygoblin_side.png");

<model,renderer,entity whatever> .SetUvOfLastTexture(0,0,16,16);

<model,renderer,entity whatever> .Add/SetTexture("textures/bla/mygoblin_bottom.png");

<model,renderer,entity whatever> .SetUvOfLastTexture(0,0,16,16);

// yes, mygoblin is a block

 

Also it doesnt matter if the Texture is a single file or not for me, thats changed fast. All i need to know is how to properly Map Textures onto Models. Where does this hidden magic happen?

Looking at the pixel coordinates in an image viewer and then using those values in code. And some trial + error.

Thanks, i have done that and i found out that my Box Renderer Entity Model is using the Texture i want it to use.

But its UV coordinates are wrong.

I need to change those UV coordinates and i dont know where to do it.

Then i futher checked AND when i make the PNG large egnouth i could pinpoint where those Wrong UVs are point at. Check this out

This Texture is 256x256.

The top right Green bar with TNT on it is where the Mapping picks the pixels.

 

I would love if i could change  to

x.model.renderer.texture.uv[0].x = 0

x.model.renderer.texture.uv[0].y = 0

x.model.renderer.texture.uv[0].x2 = 16

x.model.renderer.texture.uv[0].y2 = 16

 

Not only could i then design what Texture to use, but i could also use a Texture of 32x32 pixels, where 4 sides are 1 of those 16x16 panes, 1 is top and 1 is bottom, instead of the usual CubeTextureMapping that normally applies.

 

This is the Texture i would like to use instead (for a completly custom EntityPrimedTNTBlock):

You can just change the texture based on some conditions each time you render? Overriding getEntityTexture allows you to do this. Entities are each rendered once per frame.

Above is the Render Code, and i tried what you said with:

    @Override
    protected ResourceLocation getEntityTexture(EntityRedstoneBlastBlockPrimed entity)
    {
        return new ResourceLocation(Reference.MODID+":textures/entity/redstoneblast_block_all.png");
    }

 

But even thou it takes the right Texture, the position of the UVs is way too the right.

i try to crack this case since yesterday with no succses

[Cadiboo]

You would change the texture and have the UVs remain constant.

[mewewe8]

It works now!

 

You were right i cant change UVs.

 

This is the working Solution:

 

Its a bit big but it works and i can finish writing my tutorial.

 

THank you so much!!!

Here a proof:

[Cadiboo]

You can also use GL state and BlockRendererDispatcher#renderBlockState to achieve this probably more cleanly.
