[1.16.1]How to scare mobs

[mgen256]

I want Piglin to be scared of my blocks. Like the fire of the soul. 
but I can't find its code.
Where is that code? Or please tell me how.

Append to BlockTags::field_232865_O_ also known as piglin_repellents.

Thank you very much!

I was able to achieve it by creating a tag in the following location.

 

src/main/resources/data/minecraft/tags/blocks/piglin_repellents.json

 

{
    "replace": false,
    "values": [
        "modid:myblock"
    ]
}

 

I have something to know. I initially tried to register via an internal variable, like BlockTagsProvider, but gave up.
Is that possible?

Sorry, I'm having trouble.
I have a block that has an ON/OFF status, like a campfire.
In this case, registering the block in the tag is bad.

 

PiglinsMobsSensor has the following code.

   private static boolean func_241391_a_(ServerWorld p_241391_0_, BlockPos p_241391_1_) {
      BlockState blockstate = p_241391_0_.getBlockState(p_241391_1_);
      boolean flag = blockstate.isIn(BlockTags.field_232865_O_);
      return flag && blockstate.isIn(Blocks.SOUL_CAMPFIRE) ? CampfireBlock.func_226915_i_(blockstate) : flag;
   }

 

It looks impossible to me... Is there a solution?

[ChampionAsh5357]

The best I can think of is a makeshift old redstone block where each state is its own separate block. Overriding the `Block::isIn` function is pointless since it doesn't take in a blockstate. This just leaves `CampfireBlock::func_226915_i_`, however this can't event be accessed since its specific for SOUL_CAMPFIRE. If you wanted to do a combined implementation, then you would need to override `Block::isIn` to return true if a SOUL_CAMPIRE is passed in and have your block extend CampireBlock. From there, you would need to put it in BlockTags::field_232882_ax_ which is also known as campfires. You could then override all the methods to make your block act the way its supposed to.

 

That's the only two options I can really think of in the current state.

[mgen256]

You are wonderful to come up with the latter method.
However, both methods are hesitant to make choices.

 

If IsIn() had a state value, I wouldn't have to worry so much 😟

But I could learn a lot.
I decided to give up. Thank you very much.
