Idea: Custom scripts

📌 Feature Proposal: Custom Script Support for ChatPatches

Hi!
I’d like to suggest an idea for the ChatPatches mod — adding support for custom scripts for client-side chat message handling.

---

📖 Idea:

Introduce support for writing custom JavaScript scripts that can handle client-side events like:

• Receiving chat messages
• Displaying boss bars
• Handling titles
• Scoreboard updates

This system would allow players to:

• Automatically remove ads or unwanted messages from the chat
• Hide boss bars or titles based on conditions
• Filter messages by keywords
• Customize how chat messages appear

---

📐 How It Could Work:

• Add a "Scripts" section in the mod settings, where players can:

  • Create new scripts (with a custom name)
  • Edit the script code (written in JavaScript)
  • Delete scripts
  • Enable/disable scripts individually
  • Specify the server IP where each script should be active

• Provide built-in documentation listing the available API methods and events, for example:

  • onChatMessage(callback)
  • getServerIp()
  • event.message
  • event.remove()
  • and others

---

📦 Example Use Case:

A player could write a script like this:

onChatMessage(function(event) {
    if (getServerIp() === "example.net") {
        if (event.message.includes("advertisement")) {
            event.remove();
        }
    }
});

This would automatically remove any chat message containing the word "advertisement" when connected to "example.net".

Optionally, it could capture the next 5 messages or perform additional actions.

---

📌 Why This Would Be Useful:

• It gives players a flexible, scriptable way to control their client chat experience.
• Users could tailor chat behavior to specific servers.
• Can help block spam, manage boss bars, or automate message formatting.
• No need to edit mod code — scripts are fully managed through the UI.

---

I’m not sure how exactly to implement this yet, but I’d love to see a feature like this added to ChatPatches.

this is a cool idea!! while it's definitely not in scope at the moment, i think down the road i could look into something like providing native integration with KubeJS to accomplish this.
