[1.9] Custom chest doesn't render properly in inventory

[Cliff122]

Hi!

 

I've been tinkering with making custom chests by looking at and copying vanilla code. So far I have managed to make it work and look like a vanilla chest while placed in the world, however in the inventory and hand it has the black and pink error-texture. I have tried copying the vanilla item model, but that alone doesn't do anything. I suspect I have to use some kind of special renderer but I can't figure out how.

 

This is my current code, if you need any other classes just ask.

You need to use ForgeHooksClient.registerTESRItemStack. Yes, it is deprecated, but it is the way to go.

 

Ok, that seems so be on the right track. I looked up this example on how to use it and did basically the same like this

ForgeHooksClient.registerTESRItemStack(Item.getItemFromBlock(MBBlocks.spruce_chest), 0, TileEntitySpruceChest.class);
ModelLoader.setCustomModelResourceLocation(Item.getItemFromBlock(MBBlocks.spruce_chest), 0, new ModelResourceLocation("mb:spruce_chest", "normal"));

 

But when it tries to render, the game crashes and gives me this log: https://gist.github.com/anonymous/5ce5864ac4bd325f1e7be842b1a91dbf

[Cliff122]

Okay, thanks for the help! I got the item rendering working by adding this to my TileEntityRenderer-class.

if (te == null) {
        	te = new TileEntitySpruceChest();
        }

Is that a good solution or are there any better?

 

Also, another model related issue. Depending on the order I place them down the models glitch out when I place my custom chest next to vanilla chests. All the chests and hitboxes work as intended, only the rendering is weird. Pictures

Could it have anything to do with the fact that I am extending vanilla classes?

[Draco18s]

Yes.  There is a better way.  It's called:

 

int someVarFromTE;
if(te == null) {
    someVarFromTE = 0; //default value
}
else {
    someVarFromTE = te.getSomeValue();
}

[Cliff122]

Okay, does anyone know anything about these other rendering glitches and/or how to fix them?

That visual glitch is entirely because you're extending the vanilla chest and letting it "double-up" with the vanilla chest.  The vanilla chest is trying to be a double chest, but you're drawing your own not-double chest as well.  The visual effect is called z-fighting.
