[1.8.9] Unable to get block textures to work

Posted February 29, 20169 yr

Hi guys,

So I have a problem which I cannot wrap my head around.

To give you an idea of how my code works, I'll show you how I register my items (which works).

When I register an item, I use the following to do so:

public void register(CTBasicItem item, String id, String type) {
    this.setUnlocalizedName(Reference.resource.PREFIX + id);

    registerTexture(item, id, type);

    GameRegistry.registerItem(item, id);
}

private void registerTexture(CTBasicItem item, String id, String type) {
    ModelLoader.setCustomModelResourceLocation(item, 0,
			new ModelResourceLocation(Reference.resource.PREFIX +
					"items/" + type + "/" + id,
					"inventory"));

}

As previously mentioned, when using the above code on an item, it works perfectly.

Reference.resource.PREFIX = comtech + ":"

"items/" is the subdirectory of "item"

"type" is the subdirectory of "items". (could be dusts/ or ingots/, etc)

However if I change the registerTexture to:

private void registerTexture(CTBasicBlock block, String id, String type) {
	ModelLoader.setCustomModelResourceLocation(Item.getItemFromBlock(block), 0,
			new ModelResourceLocation(Reference.resource.PREFIX +
					"blocks/" + type + "/" + id,
					"inventory"));

}

And try to run minecraft, it crashes... it crashes hard with the following error:

Now I can see there is a nullpointerexception but I cannot figure out how to fix it...

Anyone got any ideas?

ModelLoader

and

ModelResourceLocation

are client-only classes. If you register models from common code instead of from your client proxy, you'll crash the dedicated server.

That isnt the problem, the call for that IS coming from the client proxy and not my common proxy.

Register the block with the GameRegistry first, otherwise getItemFromBlock will not work.

That worked and now minecraft is launching. But I'm still having an issue with it not finding my .json files.

I want to use a custom path in my blockstates... see below to how I want it.

Here's my file structure:

|---blockstates/

| |---- blocks/

| |--- ores/

| |--- ore_aluminium.json

|---- models/

|--- block/

| |--- blocks/

| |--- ores/

| |--- ore_aluminium.json

|--- item/

|--- blocks/

|--- ores/

|--- ore_aluminium.json

As you can see I want my ores in blockstates/blocks/ores/ but the only problem is that unless it's in just blockstates, it won't work... is there a way to tell forge to look there instead?

OK, it all works.

Now, how exactly would I use the DefaultStateMapper and setCustomStateMapper?

The code you posted shows

registerTexture

being called in the same method as

GameRegistry.registerItem

. Do you have a separate registration method for the dedicated server?

I realise it's not causing the issue that this thread is about, but it will cause issues if you don't separate client-only code properly.

Minecraft crashes when trying to start singleplayer/create new world.

Thanks for the help! Removing lithostiched (& by proxy Tectonic) as well as Supplementaries did the trick!

Minecraft crashes when trying to start singleplayer/create new world.

I've been trying to get an old modpack of mine working again (MC version 1.20.1, Forge version 47.4.8) & I finally got it to just load into the homescreen. Unfortunately, now its crashing whenever I try to start Singleplayer, specifically when its trying into the Create a New World screen. I've attached the latest Crash Report, though if that alone isn't enough I can also attach the Log in a comment. If anyone can help me figure out what's causing the issue I'd really appreciate it.
