Hi, I was hoping to find a solution to this myself and actually came quite far, but still, I have so many problems with this code. What I am trying to do is determine which face of the block the player is looking at, and since there is no simple function to do this with Bukkit, I've had to design my own way of doing it: PHP: int playerYaw = Math.round(player.getLocation().getYaw());int Yaw = playerYaw + 90;int angle = 0; if (Yaw > 360) Yaw -= 360; switch (yawToFace(playerYaw)){ case NORTH: newLoc.add(0, 0, -1).getBlock().setType(blockMaterial); player.sendMessage("north"); break; case NORTH_EAST: angle = (int) Math.round(Math.atan2(player.getLocation().getZ() - loc.getZ(), player.getLocation().getX() - loc.getX()) * 180 / Math.PI) + 180; if (Yaw < angle) newLoc.add(1, 0, 0).getBlock().setType(blockMaterial); else newLoc.add(0, 0, -1).getBlock().setType(blockMaterial); break; case EAST: newLoc.add(1, 0, 0).getBlock().setType(blockMaterial); break; case SOUTH_EAST: angle = (int) Math.round(Math.atan2(player.getLocation().getZ() - loc.getZ(), player.getLocation().getX() - loc.getX()) * 180 / Math.PI) + 180; if (Yaw < angle) newLoc.add(0, 0, 1).getBlock().setType(blockMaterial); else newLoc.add(1, 0, 0).getBlock().setType(blockMaterial); break; case SOUTH: newLoc.add(0, 0, 1).getBlock().setType(blockMaterial); break; case SOUTH_WEST: angle = (int) Math.round(Math.atan2(player.getLocation().getZ() - loc.getZ(), player.getLocation().getX() - loc.getX()) * 180 / Math.PI) + 180; if (Yaw < angle) newLoc.add(-1, 0, 0).getBlock().setType(blockMaterial); else newLoc.add(0, 0, 1).getBlock().setType(blockMaterial); break; case WEST: newLoc.add(-1, 0, 0).getBlock().setType(blockMaterial); break; case NORTH_WEST: angle = (int) Math.round(Math.atan2(player.getLocation().getZ() - loc.getZ(), player.getLocation().getX() - loc.getX()) * 180 / Math.PI) + 180; if (Yaw < angle) newLoc.add(0, 0, -1).getBlock().setType(blockMaterial); else newLoc.add(-1, 0, 0).getBlock().setType(blockMaterial); break; default: break; } What you see there is my code, unorganized and simply pasted straight from my project which is currently in debugging mode. The function yawToFace was taken somewhere from bukkit forums, here is its' associated code: PHP: public static final BlockFace[] axis = { BlockFace.NORTH, BlockFace.EAST, BlockFace.SOUTH, BlockFace.WEST }; public static final BlockFace[] radial = { BlockFace.NORTH, BlockFace.NORTH_EAST, BlockFace.EAST, BlockFace.SOUTH_EAST, BlockFace.SOUTH, BlockFace.SOUTH_WEST, BlockFace.WEST, BlockFace.NORTH_WEST }; public static BlockFace yawToFace(float yaw){ return yawToFace(yaw, true); } public static BlockFace yawToFace(float yaw, boolean useSubCardinalDirections){ if (useSubCardinalDirections){ return radial[Math.round(yaw / 45f) & 0x7]; }else{ return axis[Math.round(yaw / 90f) & 0x3]; } } Here are the problems, in order of importance: pitchToYaw's north is MineCraft's south pitchToYaw is 90 degrees greater than angle angle gives a range between -180 and 180, whereas pitchToYaw gives a range between 0 and 360 All of the code works, except from the case on "SOUTH_WEST" and "NORTH_EAST", where the pitchToYaw is about 4-10 points less than what it should be (which means that Yaw will not be greater than angle, and the block will almost always be set on the left of the clicked block) If there is another way to get around this, such as a function which tells me what face of the block the player is looking at, or if anyone can help me, I would greatly appreciate it. Thanks, Dragonphase
