I'm trying to use the "Cone of Vision" script for some of my enemies.
And here's a link to the original thread: http://www.rmxp.org/forums/showthread.php?t=11641&highlight=cone+vision
Anyway, my problem is this:
When I set up the cone for an event, if I set it to "Player Touch" then the event moves towards me, but I have to actually turn and walk into the event for the battle to activate.
If I set it to "Event Touch" then as soon as the event sees me, the battle activates before it even moves towards me...
I need it to walk towards me and activate the battle on contact... How can I do that?
Code:
