Red Color on Game_player

[cayoda]

I need a code to change the character color to Red like a aura

Example:

    |    O  |
    |  |<- Char  |
    |  |  | -> red aura on char
    | | | | || -> Red aura on char


Thanks sorry for my bad Char =) and my bad english =X

end

To turn it on and off:

game_character.aura_on = true or false
# where game_character:
# events: $game_map.events[event_id]
# player: $game_player[

To change color:

game_character.aura_color = Color.new(red, green, blue, opacity)
