« Posted 2014-03-16 18:45:59 »

I made a simple voxel engine, and I was working on the chunk class, and I got an error. I have worked with allot of arrays in the past. I barely know why this isn't working.

Chunk:

1  
2  
3  
4  
5

7  
8  
9  
10

package passage.games.pdday.world;

import passage.games.pdday.block.Block;
import passage.games.pdday.block.BlockType;

public class Chunk {
   public static final int BLOCKS_SIZE_X = 16;
   public static final int BLOCKS_SIZE_Y = 16;
   public static final int BLOCKS_SIZE_Z = 16;

   public static final int BLOCK_SIZE = 16;

   public final Block[][][] blocks = new Block[BLOCKS_SIZE_X][BLOCKS_SIZE_Y][BLOCKS_SIZE_Z];

   public void init() {
      for (int x = 0; x < BLOCKS_SIZE_X; x++) {
         for (int y = 0; y < BLOCKS_SIZE_Y; y++) {
            for (int z = 0; z < BLOCKS_SIZE_Z; y++) {
                      /*Error here--> */ blocks[x][y][z] = new Block(BlockType.AIR, x * BLOCK_SIZE, y * BLOCK_SIZE, z * BLOCK_SIZE);
            }
         }
      }
   }

   public void render() {
      for (int x = 0; x < BLOCKS_SIZE_X - 1; x++) {
         for (int y = 0; y < BLOCKS_SIZE_Y - 1; y++) {
            for (int z = 0; z < BLOCKS_SIZE_Z - 1; y++) {
               blocks[x][y][z].render();
            }
         }
      }
   }
}


Exception:

1  
2  
3  
4  
5  
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 16
   at passage.games.pdday.world.Chunk.init(Chunk.java:19)
   at passage.games.pdday.Main.init(Main.java:51)
   at passage.games.pdday.Main.<init>(Main.java:38)
   at passage.games.pdday.Main.main(Main.java:76)


EDIT:
The "Block" translates with glTranslate. That's why there is a x * BLOCK_SIZE there, so they translate properly.

You're incrementing the y variable in both z-loops.

Just read your code for like 3 minutes before you post it here. You put a y++ iterator on the z loop.
