Hello

I'm currently making an Item that thrusts you to viewing direction, and I referenced riptide code of trident for my item.

  @Override
    public InteractionResultHolder<ItemStack> use(Level pLevel, Player pPlayer, InteractionHand pUsedHand) {
        if(!pLevel.isClientSide() && pUsedHand == InteractionHand.MAIN_HAND && pPlayer.isOnGround()){

            Impale(pPlayer, pUsedHand);

            pPlayer.getCooldowns().addCooldown(this, 40);
        }
      
        return super.use(pLevel, pPlayer, pUsedHand);
   }

   public void Impale(Player pPlayer, InteractionHand pUsedHand) {

      float playerYRot = pPlayer.getYRot();
      float xForce = -Mth.sin(playerYRot * ((float)Math.PI / 180F)) * Mth.cos((float)Math.PI / 180F);
      float yForce = 100.6F;
      float zForce = Mth.cos(playerYRot * ((float)Math.PI / 180F)) * Mth.cos((float)Math.PI / 180F);
      float stabilizedForce = Mth.sqrt(xForce * xForce + zForce * zForce);
      xForce /= stabilizedForce;
      zForce /= stabilizedForce;

      pPlayer.push((double)xForce, (double)yForce, (double)zForce);
      pPlayer.sendSystemMessage(Component.literal(playerYRot + " " + xForce + " " + yForce + " " + zForce + " " + stabilizedForce + "shoo"));
   }

I sure edited a lot from source code but this isn't working somehow?

the sendSystemMessage works correctly. It prints value of variables and string, but the force isn't applying to player.

how can I make this to work?

Thanks.

Use player.setDeltaMovement(player.getViewAgle().scale(speed)

and then set player.hurtMarked to true.

if your in the server and setting velocity, that doesn’t work, you have to set hurtMarked to true, that sends the update to all the clients. Just try and add that line at the end somewhere.
