This may seem stupid, but how do I do this? I want it to talk on start.
You need to use the "show text" event command.
You'll also need to make an event in your starting area that is running as a parallel process, and a self switch turning it to the next page after the character has finished speaking.
Try playing around with the settings.
Autorun
Don't forget to do something to turn the autorun event off after it is done doing its thing.
