Thinking

A common mistake people do is use event.thinking with event.reply, however, they always run into the Interaction has already been acknowledged. error! The reason for this is because event.thinking is a response to the interaction, meaning you have acknowledged it! You should use dpp::interaction_create_t::edit_original_response instead.

Below is an example, showing how you should properly use the thinking method.

#include <dpp/dpp.h>
int main() {
dpp::cluster bot("token");
/* The event is fired when someone issues your commands */
bot.on_slashcommand([&bot](const dpp::slashcommand_t& event) {
/* Check which command they ran */
if (event.command.get_command_name() == "thinking") {
/*
* true for Ephemeral.
* You can set this to false if you want everyone to see the thinking response.
*/
event.thinking(true, [event](const dpp::confirmation_callback_t& callback) {
event.edit_original_response(dpp::message("thonk"));
});
}
});
bot.on_ready([&bot](const dpp::ready_t& event) {
if (dpp::run_once<struct register_bot_commands>()) {
/* Create a new global command on ready event */
dpp::slashcommand newcommand("thinking", "Thinking example...", bot.me.id);
/* Register the command */
bot.global_command_create(newcommand);
}
});
bot.start(dpp::st_wait);
return 0;
}

This will make the bot think briefly, then change the response to "thonk"!
