Because scripts in Roblox run at different times, it’s possible that a player’s head might not be created yet. To avoid errors, like trying to find a part that doesn’t exist, the script uses WaitForChild() to get the head part attached to the player’s character instead of using the dot operator, like player.Head.


  1. Use wait() destroy the particles after one second.
  1. Playtest the game and make sure particles briefly follow the player after touching each color.
Troubleshooting Tips
  • Make when creating a new instance that ParticleEmitter is spelled exactly as shown and inside quotations.
  • When parenting the particles, make sure to use : between playerCharacter and WaitForChild() with no spaces between.
