Adding an effect to a damaged player

[JackyBoy]

Hellow, I have been working on this new system where a player can shoot a snowball at a player, however, I would like the player that gets hit to get slowness for 5 seconds. Here is my current code:

on rightclick:
      player is holding wooden hoe
      shoot a snowball at speed 1

Listen for player damage events and check if the projectile is a snowball, and if so then you can do whatever you want (like applying slowness).
