Just looking for some help for some eventing, down below is a link of what I'm attempting to do. Bascially wanting to have 3 NPCs and one npc the player can control, trying to have them race one another and controlling the speed of all the racers via a variable. But run into the issue of the events stopping shortly and not being able to make them race upon talking to someone. Have tried setting them on a switch so they don't automatically race, and have changed all event pages to action instead of parallel but that doesn't do the trick.

Also wondering how would I be able to determine what event hits an invisible event first to determine placing too. So I can make an event based on the placings of the NPCs and the players one.

For reference I have also tried move routes for all events using a wait command for the last swimmers action, then using a switch to change graphics but can change that around to an img change instead. Also using Chain commands by : mjshi.
