Is there a way to manually trigger events like on_message or on_command_error?
Similar to manually raising a Exception
Yes there is, use the Bot.dispatch method (this is useful for creating custom events), note that you have to pass the arguments manually
bot.dispatch("message", message) # You need to pass an instance of `discord.Message`
bot.dispatch("command_error", ctx, error) # Remember to pass all the arguments
Example of a custom event
@bot.command()
async def dispatch_custom(ctx):
bot.dispatch("custom_event", ctx)
@bot.event
async def on_custom_event(ctx):
print("Custom event")
There's no docs about it so I can't give you the link, if you want to know more about it take a look at the source code
