[1.12.2] Render OBJ on item depending on NBT

Posted June 25, 20187 yr

Hello. I'm working on a mod called Crystalline (source code here), and I can't quite figure out how to use an OBJ model to render an item depending on its NBT. If anyone can help me as soon as possible, please do. I'm anticipating a release date of the mod fairly soon.

I would like to implement this rendering into the ItemCrystal class. I have already added OBJLoader.INSTANCE.addDomain(MODID); to my ClientProxy locally, but it may not be in the Git version.

ItemCrystal.java

never worked with custom item models but i found this in the Item class.. :

    @SideOnly(Side.CLIENT)
    public void setTileEntityItemStackRenderer(@Nullable net.minecraft.client.renderer.tileentity.TileEntityItemStackRenderer teisr)
    {
    	this.teisr = teisr;
    }

its client sided .. named renderer.. maybe you can change the model in there with a simple switch checking for the NBT?
but i am not sure tho..

I researched a bit, and it doesn't look like that can be used for what I need.

I have created an ItemMeshDefinition, but it doesn't seem to allow me to render an OBJ with it. (The updated code should now be committed to GitHub)

JSON file (crystalline:item/crystal_knowledge.json)

Spoiler


{
            "parent": "crystalline:item/crystal_knowledge.obj",
			"display": {
				"firstperson": {
					"translation": [1.20, 0.25, 0],
					"rotation": [ 0, 0, 0 ],
					"scale": [1, 1, 1]
				},
				"thirdperson": {
					"translation": [0.25, 0.25, 0.35],
					"rotation": [ 0, 0, 0 ],
					"scale": [0.5, 0.5, 0.5]
				},
				"gui": {
					"translation": [0, 0.5, 0],
					"rotation": [ -45, 0, 0 ],
					"scale": [1, 1, 1]
				}
			}
}

Also, I get a weird error in my log:

To specify a model based on NBT data look at vanilla's ItemBow and it's model. While it doesn't use NBT data you can easily adapt the code there to use NBT.

By the error in your log it looks like vanilla json can't have a non-vanilla obj(provided by forge) as it's parent.

I don't know that either - newer worked with Invision Community 😕

The Forum/Guides show a customized toolbar:
https://invisioncommunity.com/4guides/themes-and-customizations/editor-and-emoticons_327/customizing-editor-toolbars-r132/
But I have no idea if this applies to v5

Regarding the Forum, "Mark all as read" seems to be hidden as default but is available if I click on my profile:
https://invisioncommunity.com/forums/topic/481218-fix-for-unreadmark-read/

I saw that it works here and also fixes the one unread thread mentioned in my first post - so I had just overlooked it

The toolbar changes are just QoL - if there is no way to change it at the moment, that's fine

I understand what you're asking for, but I don't know how to do that. The settings have moved around a bit in the admin panel and I can no longer see a way of customising the editor. If you know how to customise the editor in Invision Community 5, let me know and I'll try applying it.
