Responding to button clicks
Responding to buttons is pretty simple, there are a couple ways of doing it and we can cover both.
Method 1: Hooking the InteractionCreated Event
We can hook the InteractionCreated event since button clicks are a form of interactions:
client.IntreactionCreated += MyInteractionHandler;
Now, lets write our handler.
public async Task MyInteractionHandler(SocketInteraction arg)
{
// first we check the type of the interaction, this can be done with a switch statement
switch(arg)
{
case SocketMessageComponent component:
// we now have a variable defined as 'component' which contains our component data, lets pass it to a different handler.
break;
}
}
public async Task MyButtonHandler(SocketMessageComponent component)
{
// We can now check for our custom id
switch(component.Data.CustomId)
{
// Since we set our buttons custom id as 'custom-id', we can check for it like this:
case "custom-id":
// Lets respond by sending a message saying they clicked the button
await component.RespondAsync($"{component.User.Mention} has clicked the button!");
break;
}
}
Running it and clicking the button:
Method 2: Hooking the ButtonExecuted Event
This method skips the first switch statement because the ButtonExecuted event is only fired when a button is clicked, meaning we dont have to check the type of the interaction.
client.ButtonExecuted += MyButtonHandler;
The rest of the code is the same and produces the same result.
