How to make it so something happens when a DialogChoice is clicked?

I want to know how to make something happen when DialogChoice is clicked, i remember that being possible and seeing something like that in a video.

You can use the DialogChoiceSelected event. Whenever the player chooses a certain dialog, you can fire this event and any code inside it will run.

I have to caution you though that this event is client-side only, so anything you do on this event will only be visible by the client, unless you fire a remote event to the server.

Check this resource. Even if you build your own, there is working code for this.

Weird how this doesn’t show up in the main page, and doesn’t show up in the object browser as well.
