1. Remote Events – One-Way Messages

Think of a Remote Event as sending a message without expecting a reply.

• Client → Server:

  Example: You press a button in your game. The client sends a message to the server: “Hey, I pressed this button!”

  • Server sees it and reacts, e.g., spawns an item, gives points, plays a sound.
  • Client doesn’t wait for a response—it just keeps going.

• Server → Client:

  Example: The server wants to tell all players: “A new enemy has spawned!”

  • The server sends this message, and the client reacts (e.g., shows the enemy).
  • No response is sent back to the server—it’s just a notification.

✅ Key point: No one waits for a reply. It’s like shouting “Hey!” and moving on.

2. Remote Functions – Two-Way Messages

Think of a Remote Function as sending a message and waiting for an answer.

• Client → Server:

  Example: You want to buy an item. The client asks the server: “Can I buy this item?”

  • The server checks your coins, decides if you can buy it, and sends a response back: “Yes” or “No.”
  • The client waits until it gets that answer.

• Server → Client:

  Example: The server wants to get a player’s settings: “What skin do you have equipped?”

  • The server calls the function on the client, the client responds, and the server uses the info.

✅ Key point: Someone waits for a reply. It’s like sending a text and expecting an answer.
