Why is my custom block entity causing crash?

Posted October 26, 20222 yr

Hello, so I recently created a custom block entity, and whenever I open it, I crash with an error message saying Caused by: java.lang.RuntimeException: Slot 3 not in valid range - [0,3). I know that this error is being caused by a numerical error in my container number code, but I cannot find where. Any help?

Why don't you post the full error so we can see where it is crashing?

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.

The full error is what I said at the beginning; there was no error log, just that one short message.

If this is a networking error, mojang log them at debug level

Add the following property to your run configuration in your build.gradle

Quote

property 'forge.logging.mojang.level', 'debug'

Otherwise you can use a debugger to see the full error including its stacktrace.

There was no problem when I had 3 slots, I added 3 more and then a problem happened. I think that the problem had to do with something that I forgot to change from the 3 slot code. I'll check again.

After some digging, I've found the crash report that I thought didn't exist. Perhaps this could help?

Try doing running the "clean" gradle task.

Since you are using "static final" to define some constants it might be the compiler didn't recompile something that references a constant when it changed.

Such constants get "inlined" by the compiler.

The clean task will force everything to be rebuilt from scratch the next time you build.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.

Oh my gosh, it worked! I cannot believe how simple that was! I can't thank you enough!

I think I know what your issue is.

    @Override
    public void load(CompoundTag nbt) {
        super.load(nbt);
        itemHandler.deserializeNBT(nbt.getCompound("inventory"));
        progress = nbt.getInt("altarofessence.progress");
    }

The number of slots is stored in the NBT of the block entity's item handler.

That deserialize will be loading old data that have item handlers with only 3 slots.

Add some temporary code that converts old data to new data in your load, or just create a new test world.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

[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
