hi…

I try to make voxel project from this tutorial
http://alexstv.com/index.php/posts/unity-voxel-block-tutorial-pt-4. My problem is don’t no how to use these function… because i’m new in c#…

 public void SetBlock(int x, int y, int z, Block block)
 {
     Chunk chunk = GetChunk(x, y, z);

     if (chunk != null)
     {
         chunk.SetBlock(x - chunk.pos.x, y - chunk.pos.y, z - chunk.pos.z, block);
         chunk.update = true;

         //Add these lines line
       UpdateIfEqual(x - chunk.pos.x, 0, new WorldPos(x - 1, y, z));
        UpdateIfEqual(x - chunk.pos.x, Chunk.chunkSize - 1, new WorldPos(x + 1, y, z));
        UpdateIfEqual(y - chunk.pos.y, 0, new WorldPos(x, y - 1, z));
        UpdateIfEqual(y - chunk.pos.y, Chunk.chunkSize - 1, new WorldPos(x, y + 1, z));
        UpdateIfEqual(z - chunk.pos.z, 0, new WorldPos(x, y, z - 1));
        UpdateIfEqual(z - chunk.pos.z, Chunk.chunkSize - 1, new WorldPos(x, y, z + 1));
     }
 }

i have try for 2 day and still don’t no how to do… with these

 public void add(){
	RaycastHit hit;
	if (Physics.Raycast (transform.position, transform.forward, out hit, 25)) {
		World.SetBlock (hit, new BlockLeaves ());
	}
}

i get error:

Assets/Code/AddRemove.cs(15,31): error
CS0120: An object reference is
required to access non-static member
`World.SetBlock(int, int, int,
Block)'…

what should i put in (int x, int y, int z,)?

i hope someone can clarify…

Just set ur method as static

public static void SetBlock(int x, int y, int z, Block block)
  {
      Chunk chunk = GetChunk(x, y, z);
  
      if (chunk != null)
      {
          chunk.SetBlock(x - chunk.pos.x, y - chunk.pos.y, z - chunk.pos.z, block);
          chunk.update = true;
  
          //Add these lines line
        UpdateIfEqual(x - chunk.pos.x, 0, new WorldPos(x - 1, y, z));
         UpdateIfEqual(x - chunk.pos.x, Chunk.chunkSize - 1, new WorldPos(x + 1, y, z));
         UpdateIfEqual(y - chunk.pos.y, 0, new WorldPos(x, y - 1, z));
         UpdateIfEqual(y - chunk.pos.y, Chunk.chunkSize - 1, new WorldPos(x, y + 1, z));
         UpdateIfEqual(z - chunk.pos.z, 0, new WorldPos(x, y, z - 1));
         UpdateIfEqual(z - chunk.pos.z, Chunk.chunkSize - 1, new WorldPos(x, y, z + 1));
      }
  }
