I'm starting with modding and I'm having a hard time spawning a lightning. Don't know if I'm doing something wrong here. I tried with a class extending from LightningBolt first, but can't spawn a vanilla one neither.

public static void SpawnLightning(Level level) {
	level.addFreshEntity(EntityType.LIGHTNING_BOLT.create(level));
	//level.addFreshEntity(Registry.UNSTABLE_LIGHTNING.get().create(level));
}

Is this supposed to be done differently? Also, my console is getting spammed with

[Render thread/ERROR] [minecraft/Util]: Entity lightningmobs:unstable_lightning has no attributes

Dunno why or how to fix it. This is how I am registering this.

public static final RegistryObject<EntityType<UnstableLightning>> UNSTABLE_LIGHTNING = ENTITIES.register(
	"unstable_lightning", (Supplier<? extends EntityType<UnstableLightning>>)
	() -> {
		EntityType.Builder<UnstableLightning> builder = EntityType.Builder.of(UnstableLightning::new, MobCategory.AMBIENT);
		EntityType<UnstableLightning> type = builder.build(new ResourceLocation(LMobs.MODID + ":unstable_lightning").toString());
		return type;
	}
);

Btw, what should I be sending to EntityType.Builder#build(String pId), don't know what that ID is for.

You are not setting the position for the lightning bolt entity. It is probably spawning at 0,0,0

Look at ServerLevel.tickChunk() for how vanilla does it.

I assume you are spawning it on the server?

 

See https://forge.gemwire.uk/wiki/Making_Entities for how to define the attributes for your entity and other things.

 

The parameter passed to build() is used by DFU (datafixerupper)

So it's pretty much irrelevant unless Mojang somehow know about your Entity and want to apply a fix to its persistent data. 🙂

Ok now it crashed because entityrenderer is null, I expected it because I don't know what files I could need to make a model for a lightning, or how to grab vanilla one.

Don't paraphrase errors. Show the full error message preferably by posting a link to the run/logs/debug.log
