Detect if player is completely on ground?

  1. Hey, I created this method
    Code (Text):
        public static boolean isPlayerCompletelyOnGround(HACPlayer player) {
            double check = (player.getPlayer().getLocation().getY() - player.getPlayer().getLocation().getBlockY());
            return check % BlockUtil.getRelativeBlockHeight(LocationUtil.getActualGroundLocation(player.getGroundLocation()).getBlock().getType()) == 0 || check <= 0.002;

    it checks to see if the player is completely on the ground.
    Code (Text):
        public static Double getRelativeBlockHeight(Material material) {
            switch (material) {
            case ACACIA_FENCE:
            case ACACIA_FENCE_GATE:
            case BIRCH_FENCE:
            case BIRCH_FENCE_GATE:
            case DARK_OAK_FENCE:
            case DARK_OAK_FENCE_GATE:
            case FENCE:
            case FENCE_GATE:
            case IRON_FENCE:
            case JUNGLE_FENCE:
            case JUNGLE_FENCE_GATE:
            case NETHER_FENCE:
            case SPRUCE_FENCE:
            case SPRUCE_FENCE_GATE:
            case COBBLE_WALL:
                return 0.5;
            case GRASS_PATH:
            case SOIL:
            case CACTUS:
                return 0.9375;
            case SOUL_SAND:
            case CHEST:
            case ENDER_CHEST:
            case TRAPPED_CHEST:
                return 0.875;
            case CHORUS_PLANT:
                return 0.8125;
            case ENCHANTMENT_TABLE:
                return 0.75;
            case BED_BLOCK:
                return 0.5625;
            case SKULL:
                return 0.25;
            case WATER_LILY:
                return 0.09375;
                return 0.0625;

    I just wanted to know if there was a better way I could accomplish this. Does anyone know a better way to do this, or is this the best way?
  2. Oh sht, so it is. That must be new. Or not and I just haven't noticed.
  3. Use Entity.isOnGround instead of Player.isOnGround maybe. The Entity.isOnGround() is not deprecated.

  4. it will still run player.isOnGround() even if you cast it as an entity...
    believe me, if spigot had a method for it I would use it. What I am trying to ask is if anyone knows of a more efficient method than the one above.
  5. Please, don't post if you have no clue.

    OP, it really isn't that complicated of a check, I'm sure your method is fine. You could also dig into the source code and find how out isOnGround is calculated.
  6. Lol, I tried xD ( Was bumping thread )

  7. See if their Y velocity is 0?
  8. That makes no sense at all.
  9. This is getting really off-topic, THE METHOD ABOVE WORKS! What I am trying to figure out is if that is as efficient as I can make it.
  10. Would Player.getVelocity().getY() not work?
  11. If Player.getVelocity().getY() works, then I feel like it would be more efficient.
  12. what

  13. No, I'm not aware of any such method. And no one has yet suggested a more efficient method.
    I'm not sure how to explain this, but no, it is very wrong. X/Y/Z values work in an entirely different way than you think.
  14. Never heard of OOP, have you?

    Players flying. Haven't tested, though.
    • Agree Agree x 1
  15. OOP? XD
  16. I think I understand what Hunky is trying to say here. If your velocity in the Y direction is 0, then you must be on the ground(or gravity and a velocity have exactly equaled out, making this method having a slim chance of being unreliable). This method would obviously work only while not flying.
