    • Gameplay

      Fireworks, eggs, snowballs, and splash potions of harming fired from dispensers don't knock back mobs, but they do when thrown by the player or a mob such as a snow golem or witch.

      Steps to Reproduce:

      • Build the setup as shown in the attachment below. setup.png
      • Place some snowballs inside of the dispenser.
      • Summon a husk on the diamond block.
      • Use the lever to activate the dispenser and watch the husk closely.

      Observed Behavior:
      Projectiles fired from dispensers don't deal any knockback to entities.

      Expected Behavior:
      Projectiles fired from dispensers would deal knockback to entities.

      Note

      Arrows are not affected by this bug, as they knock back mobs when fired either from a bow or a dispenser.
