[1.19.2]datapack gen + spawning full estructure from a single block

[perromercenary00]

using the tall towers example i wanna spawn a complex villages like old version 1.8 

the plan until now consist on making a especial block to do all the job following the steps 

* fix and level up the land to remove the stepped parts and  pitfalls 

* spawn village fence in the borders 
* spawn the sewer tunnels 

* spawn  the gravel / compacted grass paths

* houses 

* villagers / animals 

and spawn that block in the  world using the datapacks system 

 

this is what i have 

 

the data packs works and spawn the block in the world  but the blocks dont pops up 
at this point only has the code to level up the terrain 

 

######
the trouble
seem like data packs put blocks in the world without triggering the internal block 

i try this tree things but nothing triggers 

	    // ########## ########## ########## ##########
    public void tick(BlockState blkstate, ServerLevel warudo, BlockPos blkpos, RandomSource randomsource) {
        System.out.println("\n\ntick()\n\n");
        warudo.setBlock(blkpos, Blocks.AIR.defaultBlockState(), 10);
        
        AreaCircular ac = new AreaCircular(warudo);
        ac.setRadio(32.0F);
        ac.aplanar_area_circular(blkpos);
        ac.bm.setBlocks();
    }    
	       @Override
       public void setPlacedBy(Level warudo, BlockPos blkpos, BlockState p_49849_, @Nullable LivingEntity p_49850_, ItemStack p_49851_) {
           System.out.println("\n\nsetPlacedBy()\n\n");
	        warudo.setBlock(blkpos, Blocks.AIR.defaultBlockState(), 10);
        
        AreaCircular ac = new AreaCircular(warudo);
        ac.setRadio(32.0F);
        ac.aplanar_area_circular(blkpos);
        ac.bm.setBlocks();
	
       }
       
       @Override
       public void onPlace(BlockState p_60566_, Level warudo, BlockPos blkpos, BlockState p_60569_, boolean p_60570_) {
           System.out.println("\n\nonPlace()\n\n");
        warudo.setBlock(blkpos, Blocks.AIR.defaultBlockState(), 10);
        
        AreaCircular ac = new AreaCircular(warudo);
        ac.setRadio(32.0F);
        ac.aplanar_area_circular(blkpos);
        ac.bm.setBlocks();

       }       
	

 

#####
may the block spawn process in a pseudo level of something i dont know

i need way to trigger the block on spawn and launch   ac.aplanar_area_circular(blkpos); to start the process


thanks for your time

This isn't something I know a lot about, and you don't show your relevant code so I have no idea what you are really doing.

 

Anyway (guessing):

Blocks spawned using worldgen/structures are not "placed" so those events won't fire. e.g. floating sand or gravel created by world gen doesn't fall.

 

Your tick event won't fire unless you also override isRandomlyTicking() or set the property in the block properties.

Why is this not a block entity if it is a special block? You can use proper ticking.

 

I believe the correct way to do what you are trying to do is using the TerrainAdjustment/Beardifier.

But like I said, I don't know much about structures, except Mojang seem to change how they work with every release. 🙂

this block is a common block 
its weird how it dont work if i just put the code on   

 public BlockState getStateForPlacement(BlockPlaceContext context) {}

thats why i think there exist some pseudo Levels only having access to reduced part of database 

soo i was using the tick the button and the presure plate use to reset to normal 
thats how i manage to set the ladder blocks and retrieve them

Spoiler

 

###########################

from the minecraft terrain generation i dont think its gonna fit mi desires 
is like a mi thing i want the main area round, circular and i want the area leveled using slabs so the max inclination goes to like 22.5 degrees 

way the village looks always different based on the previous terrain characteristics 
sorry i dont speak english so mi gramatical thing is wrong 
i need to fix the grass slab color thing is weird how it looks when the grass has two diferent colors 
 

############################

anyway let say i change from a common block to an TileEntity block and make it detonate at 10 ticks of existing 
the extructure its 25chunks big

 

####################################################################################################

soo i need way to check if those chuncks alredy exist

and if not i need to force minecraft to generate those chunks 
 

can you help me whit those two things

I still have no idea what you are trying to do.

Or what you are currently doing and which part does not work.

 

Your problem is not your grammar.

Your problem is you jump randomly from block placement, to grass colors, to ladders, to terrain generation and finally to chunk loading.

 

The one part I do understand is the last part.

See the Level.getChunk() methods for querying and loading/generating chunks.

 

On your "pseudo levels", I think you are referring to the ProtoChunk vs the real runtime LevelChunk?

e.g. look at the difference in setBlockState() for them.
