I want to generate a structure like Strongholds and Mineshafts. I need it to generate a exact amount of times and to be randomly shaped. If somebody could please give me an example or an explanation on how to do this, it would help me so much.

Go to youtube. Type in "theinstitutions" and go to his playlist for structure generation. I know they are for an older version of Minecraft, and they may be for ModLoader, but that doesn't matter. The WorldGen** file (** being the name you give it) is the same across the amount of time and API used. The only thing that changes is instead of world.setBlockWithNotify();, its world.setBlock(); Pretty easy really.

 

Another difference is the that instead of generating the structure in the world from your main mod file, you make it generate using the normal ore generation stuff.

 

 

As for the randomly shaped structures, I believe you would have to code a new structure for every "Random" structure you want, that uses a random.

 

something like this: (Note that this method will be explained in the afore mentioned tutorial)

public void generate(Random random) { // I have added the random for the 'random' structure check
    Random rand = random;
    int randomNumber = rand.nextInt(3); // this generates a random number between 0 and 3
    
    switch(randomNumber) {
    case 0:
        world.setBlock(x, y, z, Block.stone.blockID); // x, y, z variables being defined in the tutorial
        break;
    case 1:
        world.setBlock(x, y, z, Block.wood.blockID);
        break;
    case 2:
        world.setBlock(x, y, z, Block.blockDiamond.blockID);
        break;
    case 3:
        world.setBlock(x, y, z, Block.blockGold.blockID);
        break;
    }
}

 

That would be the sorta thing needed for making a "randomly shaped" generated structure. All you have to do is change the shape that the blocks that get spawned make the structure have the different shapes.

 

I hope that helps... If not I wasted 5 minutes of my life writing this

thanks, but i have already made the base structure. I just want it to generate like when using StructureStart. I know it would work extending it and generating it in a knew dimension but i don't know how to do it in already existing ones.

What do you mean, "I don't know how to do it in already existing ones."?

 

That doesn't quite make sense to me

I don't know how to add a StructureStart to a already existing dimension.

Ahh. Do you know how to generate ores in the world? Overworld/Nether/End? If you do its EXACTLY the same concept, you just have to generate the structure instead. I'll explain a bit better later.

I have already made it generate, but i need to know were it is generated before it is, so that i can make a device, that points towards the closest structure.

Save a list of locations. I don't know much about this, but I think it involves either world.mapStorage or world.perWorldStorage.

Thanks that worked
