When riding a camel, you can use a crossbow or bow to shoot the camel you are riding and or the player that is also riding a camel. Although, you cannot damage the Camel or other player using a sword

steps to reproduce:

1: ride in the back of a camel with another player

2: fire a bow or crossbow

3: if aiming down or at side of player, it can hit the camel or player, even if not aiming there.

expected results: like a sword, collision of arrow should ignore camel or accompanying player

actual results: arrow hits camel or other player, which can be annoying if trying to shoot something that is small or close
