Block Transform doesnt work.

[drok0920]

Hello,

I have been trying to make a block that looks like an item thats on the ground.  I have gotten it to render the item properly but i cant see to get it to rotate or be offset.  Here is my JSON:

 

{
    "parent": "item/generated",
	"display": { 
		"rotation": [90, 0, 0]
	},
    "textures": {
        "layer0": "poverhaul:items/rock_0"
    }
}

 

Minecraft outputs no errors but the model is never rotated in the world.

If you look at the model format, you'll see that your display section is incorrect. You need to specify the display transformations for a specific transform type (e.g. thirdperson_righthand, ground).

Ok but which one do i use.  I tried ground but that didnt work.

I just re-read your post and noticed that you're using a block. Item display transformations are only applied when the model is rendered for an item, they're not applied when the model is rendered for a block in the world.

 

I think you can specify a base TRSRTransformation for a model using Forge's blockstates format. Set the "transform" key of a variant to an object with either a single "matrix" key or some combination of "translation", "rotation", "scale" and/or "post-rotation" keys. You can see a simple example here in RFTools and a slightly more complex example here in a Forge test mod.

 

Look at ForgeBlockStateV1.TRSRDeserializer to see how Forge deserialises TRSRTransformations.

So i should do something like this in my block state?  

 

{
    "variants": {
        "normal": [
			{"model": "poverhaul:rock_block", "x": 90 }
		]
    }
}

That will just rotate your model by 90 degrees about the x axis; for anything more complex than 90-degree rotations about the x and y axes you need to use TRSRTransformations.

And how would i add that?  And will that method work for z aswell or just x and y

[Draco18s]

JSON transformations are only X and Y, it assumes that Z rotation is just a combination of X and Y (because North is basically the same as East)

[drok0920]

Ok i forgot that Y is up not Z but how would i use TRSRTransformations.
