Fade event script

[Northern49]

I tried to make a script that fades an event but I failed. Could someone tell me what I'm doing wrong?

class Spriteset_Map
  def fade_event(char, duration)
    # sprite_character equal to:
    sprite = @character_sprites.detect {|s| s.character == char }
    # Character opacity duration
    sprite.opacity(duration)
  end
end

class Scene_Map
  attr_reader :spriteset
end

class Interpreter
  # flash_event(index[, color[, duration]])
  #
  # Index: The event that is to fade
  # Duration: The time it takes for sprite to disappear completely
  def fade_event(index, duration=20)
    if $scene.instance_of?(Scene_Map)
      if index != 0
        event = $game_map.events[index]
        if event.nil?
          raise IndexError, "fade_event: Index error"
        end
      else
        event = $game_player
      end
      $scene.spriteset.fade_event(event, duration*2)
    end
  end
end

Well how excactly did it fail? Did game crash, or did it just not do anything?

 

[Northern49]

crash on title screen

 

[tensuke]

Did it give an error or just close itself?

Also, your def update is not in a class.

 

[Northern49]

Error
Fixed the def update part but now I get syntax error on title screen.

 

[tensuke]

Well then what does it say?

 

[Northern49]

Script 'Fade Event' line 18: SyntaxError occurred.
Hold on, I fixed that.

Now it says:

Script 'Fade Event' line 10: NoMethodError occurred.

Undefined method '-' for nil:NilClass

I believe it's because your sprite_opacity variable isn't yet defined.

 

[Northern49]

what defines the opacity of a sprite? I'm looking at the help file but it doesn't tell you how to organize methods, just what they mean.

 

[tensuke]

I've been working on it with little results...Hopefully a more experienced scripter can help, if not, I'll be back in a few hours to check anyway...Hope you get this!

 

[Northern49]

Apparently @sprite.opacity defines the opacity of a sprite, but how do I indicate to the script which sprite I am speaking of?

Well, I worked on this for hours, with little luck. First, I was able to make the event disappear after a few seconds, but not fade. Then, I was able to make every event and the player fade out, and when it all faded, everything went back to normal except the event to be faded. This would work, but only if the event was the only event visible onscreen. Not very handy, no.
I could not figure out why everything faded. Finally, I just stopped and used events. This can go in an event or common event, and you can use either a set number(e.g. 3,17,8) or a variable(e.g. $game_variables[1],$foo) for the event's id. Maybe you can translate this to a script, I dunno.

First put this in Game_Character, or add a new script above main that adds it in.

  attr_accessor :opacity

Then, use this in an event.

Loop
Conditional Branch: Script: $game_map.events[3].opacity <= 0
Break Loop
Else
Script: $game_map.events[3].opacity -= 8
Wait: 1 frame(s)
Branch End
Repeat Above

Sorry I couldn't be of much more help! Good luck to you though! :D
