SE volume change over distance

じ☆ve冰风

Introduction
This little script calculate the distance between an event and the player and the volume for a sound that can be played by that event.

Features
- Friendly little helper
 
How to Use
Simple put a call script command in your event.

In my example I use a cat as an event that randomly plays a "meow" every five seconds with a probability of 25%.
The maximum volume is 50 and the maximum distance the sound is played is 20.

The call script command should be like this:
 
@>Control Variables:[0021:Miau] = Random No.(0..100)
@>Conditional Branch; Variable[0021:Miau]<=25
  @>Script: RPG::SE.new("Cat", volume(@event_id,20,50), 100).play
  @>Wait:300 frame(s)
  @>
: Else
  @>Wait:300 frame(s)
  @>
: Branch End
@>

# Parameters:
# eventID : ID of the event that produces the SE
# md : maximum distance up to which you can hear the SE
# mv : maximum volume of the SE
# return : actual volume depending on the actual distance
#
# Example:
# RPG::SE.new("Cat", volume(@event_id,20,50), 100).play
#------------------------------------------------------------------------------

def volume(eventID, md, mv)

  x1 = $game_player.x

  y1 = $game_player.y

  x2 = $game_map.events[eventID].x

  y2 = $game_map.events[eventID].y

  d = Math.sqrt((x2-x1)**2 + (y2-y1)**2).round

  v = mv-(mv*d/md).round

  if v < 0 then

    v = 0

  end

  return(v)
