by V.M.
Introduction
This small script will allow you to use the script portion of conditional branches to activate events based on player proximity. Uses could be monster groups that chase down the player or lights that activate when the player walks near them, or anything else you can manage to do with it.
How to Use
Proximity Detection Script
Configuration consists of setting a default Proximity Range within the script
Usage: By setting an event to Parallel Process and using a Conditional Branch
within that does the script call: Proxy.inprox?(@event_id) you can have
the commands within fire off when the player is within or not within
proximity.
Common Usage:
Proxy.inprox?(@event_id) for checking for player within default range
Proxy.inprox?(@event_id, #) for checking for player within # range
Proxy.inprox_d?(@event_id, [#]) for directional checking
All calls return true if within range and false when not
Advanced Usage:
Proxy.inprox?(nil, #, x, y) for checking for player within # range
of a x,y point on the map
Any errors involving Game_Interpreter usually means the script call was mispelt
so double-check if that occurs
