Ok, so I am trying to get a feel of structure generations and what can be done with it and im trying to generate a village for example when you right click with an item called Generator1. Any suggestions on how to go about doing that?

Mark a point as the center and the do setblock so many x y and z from it to make what you want.

SetBlock? How would i generate a village like that?

The basic is simple

 

    public boolean onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9)
    {
                   par1World.setBlock(par2, par3, par4, BlockID);
     }

 

par2 is your X coordinate of your block

par3 is your Y coordinate of your block

par4 is your Z coordinate of your block

BlockId is the block you want to place at that coordinate

 

Here is some example code im using in my mod to build a small tent

 

public boolean onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9)
    {
    	par1World.spawnParticle("smoke", par2, par3, par4, 0.1F, 0.1F, 0.1F);
    	
    	par1World.setBlock(par2, par3, par4,61);
    	par1World.setBlock(par2, par3+1, par4,61);
    	par1World.setBlock(par2, par3+2, par4,35);
    	
    	par1World.setBlock(par2-1, par3, par4,58);
    	par1World.setBlock(par2-2, par3, par4,35);
    	par1World.setBlock(par2-1, par3+1, par4,35);

    	par1World.setBlock(par2+1, par3, par4,58);
    	par1World.setBlock(par2+2, par3, par4,35);
    	par1World.setBlock(par2+1, par3+1, par4,35);
    	
    	par1World.setBlock(par2-1, par3, par4-1,85);
    	par1World.setBlock(par2-2, par3, par4-1,35);
    	par1World.setBlock(par2-1, par3+1, par4-1,35);
    	par1World.setBlock(par2+1, par3, par4-1,85);
    	par1World.setBlock(par2+2, par3, par4-1,35);
    	par1World.setBlock(par2+1, par3+1, par4-1,35);
    	par1World.setBlock(par2, par3, par4-1,85);
    	par1World.setBlock(par2, par3+1, par4-1,85);
    	par1World.setBlock(par2, par3+2, par4-1,35);  	
    	
    	par1World.setBlock(par2-2, par3, par4+1,35);
    	par1World.setBlock(par2-1, par3+1, par4+1,35);
    	par1World.setBlock(par2+2, par3, par4+1,35);
    	par1World.setBlock(par2+1, par3+1, par4+1,35);
    	par1World.setBlock(par2, par3+2, par4+1,35); 
    	
    	return true;
    };

Now i am running into a problem where it is returning both feet post, and eye pos.

 public boolean onItemUse(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, World par3World, int par4, int par5, int par6, int par7, float par8, float par9, float par10)
  {
	World world = par3World;
	EntityPlayer ply = par2EntityPlayer;
	double posX = ply.lastTickPosX;
	double posY = ply.lastTickPosY;
	double posZ = ply.lastTickPosZ;
	System.out.println("X: " + posX);
	System.out.println("Y: " + posY);
	System.out.println("Z: " + posZ);
	System.out.println("Int 1: " + par4);
	System.out.println("Int 2: " + par5);
	System.out.println("Int 3: " + par6);
	System.out.println("Int 4: " + par7);
	System.out.println("Float 1: " + par8);
	System.out.println("Float 2: " + par9);
	System.out.println("Float 3: " + par10);

	return true;
}

This is what it outputs:

You can find the block right clicked on with a Forge event. Heres some code:

@ForgeSubscribe
public void buildVillage(PlayerInteractEvent event)	
{
if (Minecraft.getMinecraft().thePlayer.getCurrentEquippedItem() == youritemid)
  {
    //event.x, event.y,event.z are the block coordinates for the block you right clicked on
    
  //your code for generating
  }
}

Oh, thank you , i will for sure try that out

 

Wait, how would i get my item in the if statement? Its probably obvious but im drawing a blank. Because it is asking for an itemstack but my item is an item...

New itemstack(name of item)

Wow, (facepalm) and thank you
