[1.11] Detecting a Structure near a TE.

[Lambda]

Hey there, so I'm trying to find a way to detect 2 quartz blocks and a gold block on top, on each side.. However, I don't know how to get started. I could do EnumFacing.Horizontals , however finding the two blocks above the block that is detected by the forloop is where I'm stuck..

 

What would be the best way for the TE to detect if there is a 3 high structure (with the top of them being gold blocks) on each side.

[Draco18s]

pos.offset(facing).up()?

[Lambda]

How would I put all of this? Multiple for loops? 3 positions for different blocks?

[Draco18s]

Loop over the EnumFacing horizontal values.  That's the "facing" in my code above.

[Lambda]

Would something like this work?

public void lookForBlocks(){
        for(EnumFacing facing : EnumFacing.HORIZONTALS) {
            BlockPos quartzPos = pos.offset(facing, 5);
            BlockPos quartzPosUp = pos.offset(facing, 5).up();
            BlockPos goldPos = pos.offset(facing, 5).up(2);

            IBlockState quartz = world.getBlockState(quartzPos);
            IBlockState quartzTop = world.getBlockState(quartzPosUp);
            IBlockState gold = world.getBlockState(goldPos);

            if((quartz.getBlock()) == Blocks.QUARTZ_BLOCK && quartzTop.getBlock() == Blocks.QUARTZ_BLOCK){
                if(gold.getBlock() == Blocks.GOLD_BLOCK) {

                }
            }
        }
    }

 

Now how would I make sure all four sides are present?

Check if one doesn't exist rather than if they all exist.

[Draco18s]

That if statement will detect if that side is properly constructed.

 

Check if one doesn't exist rather than if they all exist.

 

You'll need a boolean and set the boolean to false if a side fails.

 

Or you can use a counter to count successes and check if successes == 4.

[Lambda]

If i use a counter, then everytime the forloop runs, which is every tick, the counter will increase by one again and again even if one side is there.

[Animefan8888]

If i use a counter, then everytime the forloop runs, which is every tick, the counter will increase by one again and again even if one side is there.

Think Local not global.

[Lambda]

It will still increment every tick

[perromercenary00]

i do something like this but was because i do some complicated things whit mi mod in that time

 

all mi structures was designed to occupy only one chunk and set the block whit the tile entity at the center of the chunk at y=0

 

so just check if at the center of the chunk is one of mi structure blocks and then also have the facing for the structure

 

but this obviously wont works for vanilla or other mods structures

 

[Animefan8888]

It will still increment every tick

public void update() {
    structureCheck();
}

public int structureCheck() {
    int structureCount = 0;
    for (int i = 0; i < 10; i++) {
        structureCount++;
    }
    return structureCount;
}

What is the value of structureCheck every time it is called?

[Lambda]

    public void lookForBlocks(){
        int count = 0;
        System.out.println(count);
        for(EnumFacing facing : EnumFacing.HORIZONTALS) {
            BlockPos quartzPos = pos.offset(facing, 5);
            BlockPos quartzPosUp = pos.offset(facing, 5).up();
            BlockPos goldPos = pos.offset(facing, 5).up(2);

            IBlockState quartz = world.getBlockState(quartzPos);
            IBlockState quartzTop = world.getBlockState(quartzPosUp);
            IBlockState gold = world.getBlockState(goldPos);

            if((quartz.getBlock()) == Blocks.QUARTZ_BLOCK && quartzTop.getBlock() == Blocks.QUARTZ_BLOCK){
                System.out.println(facing);
                if(gold.getBlock() == Blocks.GOLD_BLOCK) {
                    System.out.println("structure on: " + facing + " is complete"); 
                    count++;
                }
            }
        }
    }

 

well your example will always make count = 0, because your setting it to 0 every time the update is called. like in my, the count never increases, even it the println prints.

[Animefan8888]

That is because you are printing the count after setting it to 0...

[Lambda]

Makes sense, now it works

[Lambda]

Is there a better way than this to iterate though nearby chunks than this?

 

    public List<Chunk> nearbyChunks(World world) {
        List<Chunk> list = new ArrayList<>();
        list.add(world.getChunkFromChunkCoords(world.getChunkFromBlockCoords(pos).getPos().chunkXPos, world.getChunkFromBlockCoords(pos).getPos().chunkZPos));
        list.add(world.getChunkFromChunkCoords(world.getChunkFromBlockCoords(pos).getPos().chunkXPos+1, world.getChunkFromBlockCoords(pos).getPos().chunkZPos+1));
        list.add(world.getChunkFromChunkCoords(world.getChunkFromBlockCoords(pos).getPos().chunkXPos-1, world.getChunkFromBlockCoords(pos).getPos().chunkZPos-1));
        list.add(world.getChunkFromChunkCoords(world.getChunkFromBlockCoords(pos).getPos().chunkXPos+1, world.getChunkFromBlockCoords(pos).getPos().chunkZPos-1));
        list.add(world.getChunkFromChunkCoords(world.getChunkFromBlockCoords(pos).getPos().chunkXPos-1, world.getChunkFromBlockCoords(pos).getPos().chunkZPos+1));

        return list;
    }

[Animefan8888]

Why are you using World#getChunkFromChunkCoords and then to get the chunk coords you get the chunk from the block coords... Just use World#getChunkFromBlockCoords(BlockPos).

[Lambda]

Well because I'm getting the ones one next to, because ChunkPos are like: 0,1 1,0, correct? So adding one the the chunkpos will just shift over / up / down instead of adding 16.. atleast that was my thought process

Not quite adding 16, it is a bit shift. Tou are doing more processes the way you are doing it.

[Lambda]

So what should I change it to?

[Animefan8888]

So what should I change it to?

int xCoord = (getPos().getX() >> 4) + 1;
int zCoord = (getPos().getZ() >> 4) + 1;
worldObj.getChunkFromChunkCoords(xCoord, zCoord);

This will get a chunk that is offset by one in the x and z (chunk)position.
