Command responder - S3nS3IW00/JCommands GitHub Wiki

A class that takes out the necessary methods from Javacord's implementation to be able to send a response to the command. An instance of this can be found in every event.

Responding

There are three types of responses:

• immediately response
• late response
• modal response

Immediately response

This can be used when the response does not take more than 3 seconds. So basically for responding to errors this could be a good choice.

Responding immediately:

event.getResponder().respondNow()
    .setContent("This is a response")
    .respond();

Reponse can be sent only for the user by setting the MessageFlag.EPHEMERAL flag on the response with InteractionImmediateResponseBuilder#setFlags(MessageFlag...)

Late response

This must be used when the response takes more then 3 seconds. It is a good practice to use this when the response depends on a proccess. In this case the - actual - response has to be sent within 15 minutes, otherwise response to the command cannot be sent.

To be able to respond lately, it has to be indicated within 3 seconds that this response takes more time to proceed. After the process a follow-up message has to be sent that will be the actual response. This can be done by the following way:

event.getResponder().respondLater().thenAccept(updater -> {
    updater.setContent("The response takes more time to proceed.").update();

    // do the process that does not take more time than 15 minutes

    event.getResponder().followUp()
      .setContent("This is the actual response.")
      .send();
});

Late response also can be sent for only the user with CommandResponder#respondLaterEphemeral() method.

Modal response

A modal can be opened in a response to the command usage. Since this resource does not have any specific about modals, more info can be found here.

For example:

event.getResponder().respondWithModal("modalId","Modal Title",
    ActionRow.of(TextInput.create(TextInputStyle.SHORT, "text_input_id", "This is a Text Input Field")));
