comparing picture coordinates with a call script?

[AceJP]

Hey guys.

Heres the skinny.

I'm make a game where the player is displayed as a picture at x,y coordinates.
No problem.

next, as he gets close to other pictures, they are repelled by the player.
Again, no problem.

To do this, I have an event set on Parallel process running a call script to controll each enemy picture that says

[conditonal event-Script]

($game_variables[@event_id] - $game_variables[1]).abs <= 30
and
($game_variables[@event_id + 50] - $game_variables[2]).abs <= 30

then... repel enemy picture. by adding/subtracting 1 from the enemies x/y depending on where they are in relation to the player.

[end]

where:
$game_variables[@event_id] = enemies picture X coordinate
$game_variables[@event_id + 50] = enemies picture Y coordinate
$game_variables[1] = Players X
$game_variables[2] = Players Y

now my question is this. I would like to add the magnetic effect so that enemies repel eachother as well.

So, is there a method, and how would I implement it, that would check to see if a picture is within 30 pixels of another picture, and if it is, add/subtract to the correct variables so they are repelled?

Thanks!

The game's pictures can be retrieved using "$game_system.pictures".  The game system actually has two sets of pictures, one for map pictures and the other for battle pictures.  To find the coordinates of a picture you can use these two functions:

# Returns the picture's X coordinate.
def getPictureX(index)
  index+=$game_temp.in_battle ? 50 : 0
  return $game_screen.pictures[index].x
end
# Returns the picture's Y coordinate.
def getPictureY(index)
  index+=$game_temp.in_battle ? 50 : 0
  return $game_screen.pictures[index].y
end

thanks.

It's used on the map though. So the pictures have id's.
I'm using the call script
$game_screen.pictures[id].show("name", origin, x,y,zoom x, zoom y, opacity, blend)
And i already know the coordinates.
What i need is a method to compare the coordinates with all the other pictures.

thanks!

edit-
maybe you knwo whatyour talking about, I don't know much abour RGSS.
How would I implament that code? And does it check the other pictures coordinates?
