[Other Question] Is there anyway to activate an event by touching another event?

I'm trying to make the rival sprite take the player to the lab but I have no idea how to get him to do that straight after his text on the event you stand on.

You need to use switches, or how the event starts(Search on Youtube or Wiki, my english is bad so i don't want to make a tutorial here...)

If you use pbSetSelfSwitch(X,"A",true), being X the number of the event that you want to activate, you can start one event while another is working. Example --> pbSetSelfSwitch(40,"A",true)

This script activates the A switch of that event, so be sure that the things that you want are in the page activated with the A switch.

I don't know if this is what you asked, but is a very useful method.

can't you simply let the trigger event you are standing on move the Rival and the Player via 'set move route' commands?

check the rival controller events on Route 3 example map
