Making an event trigger another event via touch

Does anybody know how I can make an event trigger another event when it touches said event? In a game I am working on, the player is racing several NPCs and I want the NPCs to trigger an event if they cross the finish line first.

You can have an autorun event, with the conditions being the location of the finish line for the NPCs.

RPG Maker XP doesn't have the option to make one event trigger another via touch, so instead you'll have to work with variables.

You can either set up a variable that increases when a NPC moves towards the goal, and have a conditional branch where when your variable reaches the number of steps required to reach the goal, and have an event happen.

There's another way to do it, but it's a little bit more complicated (plus, a lot more eventing)
