[1.19.2] Custom shader not rendering on BlockItem

Posted March 3, 20232 yr

Hi, so I recently made a shader with OpenGL and I'm able to get it to render on the block in the world but I'm having trouble trying to get the actual BlockItem to render. I'm also using GeckoLib & CodeChickenLib, heres what it looks like in game:

Here's my code:

I'm also not missing any block/item JSON's so I'm kind of confused. I have been able to get this working in 1.16 but I cant seem to get it working in 1.19.2

Any help appreciated. Thanks 🙂

You need to add a BEWLR to the item by extending BlockItem, overriding `Item#initializeClient`, have `#getCustomRenderer` return your BEWLR extension, then render the itemstack using your BER there.

Hi, thanks for your reply. I have done this however I am still having the same problem. Here's my new code:

    }

        return PlayState.CONTINUE;

        consumer.accept(new IClientItemExtensions() {

            public BlockEntityWithoutLevelRenderer getCustomRenderer() {

                return bewlr;

            }

        });

    };

    @Override

        data.addAnimationController(new AnimationController<>(this, "controller", 0, this::predicate));

    }

    @Override

        return FACTORY;

    }
}

Figured it out. I had to put "parent": "builtin/entity" in the block models json. My bad XD

[1.21.3] How to add effects to food?

game changed the way you create foods.
for example minecraft 1.21.8 code for the golden apple is

Foods.java
public static final FoodProperties GOLDEN_APPLE = new FoodProperties.Builder().nutrition(4).saturationModifier(1.2F).alwaysEdible().build();

Items.java
public static final Item GOLDEN_APPLE = registerItem("golden_apple", new Item.Properties().food(Foods.GOLDEN_APPLE, Consumables.GOLDEN_APPLE));

Consumables.java
public static final Consumable GOLDEN_APPLE = defaultFood() .onConsume( new ApplyStatusEffectsConsumeEffect( List.of(new MobEffectInstance(MobEffects.REGENERATION, 100, 1), new MobEffectInstance(MobEffects.ABSORPTION, 2400, 0)) ) )

How to add my mob to another mod's biome in 1.20.1.

You can add mob spawns using Forge's Biome Modifiers feature. I won't go into details on how to use a data generator for them, but here's a simple example:
{ "type": "forge:add_spawns", // Required "biomes": "#namespace:biome_tag", // Accepts a biome id, [list of biome ids], or #namespace:biome_tag "spawners": { "type": "namespace:entity_type", // Type of mob to spawn "weight": 100, // int, spawn weighting "minCount": 1, // int, minimum pack size "maxCount": 4 // int, maximum pack size } }This JSON file would go somewhere like this: data/modid/forge/biome_modifier/your_biome_modifier.json
