Special Comments

[PK8]

Okay, need a bit of help on this. You know those totally special comments which would affect the game if it said something in particular? (Like Wora's sprite mover or Kylock's Light Effects)

Here's what one of those special comments codes would look like.
Snippet of code taken from Kylock's Light Effects and I changed some things up.

Code:

for a in $game_map.events.values
      next if a.list == nil
      for i in 0...a.list.size
        if a.list[i].code == 108 and a.list[i].parameters == ["Something"]
        # something happens here
        end
      end
    end

Say, if I wanted to type something, as a special comment for an event, like this:

Something 5

5 being any number you could put in and that number somehow affecting a particular event, what changes would I have to make in the code?

You can use the split method for strings:

Code:

for a in $game_map.events.values
      next if a.list == nil
      for i in 0...a.list.size
        if a.list[i].code == 108 and a.list[i].parameters[0][0,9] == "Something"
        # something happens here
          substrings=a.list[i].parameters[0].split(' ')
          variable=substrings[1].to_i
        end
      end
    end

[0][0,9] will test the first 9 chars of the first parameter for a match with "Something",
split(' ') returns an array of substrings using the space as separator,
finally to_i is needed to convert the string, in your example "5", into a number,
then do what you want with that...

EDIT: mmm there's something wrong with that... FIXED

Ah thanks. Now I want to use it on an event which contains that comment, how would I go about doing that? :o

[Charlie Fleed]

Give me a specific example, you're a little too vague and there are at least a couple of ways to access these values in an event.

[PK8]

My apologies. Let's say for example...
I want to move an event using comment Something 5 6. The 5 would move the event's x coordinate and the 6 would move the event's Y coordinate. Just an example. (I dunno what I might actually use it for but this comment stuff is so cool.)

Okay, you could do something like this

Code:

class Scene_Map
  def move_events_with_comments
    for a in $game_map.events.values
      next if a.list == nil
      for i in 0...a.list.size
        if a.list[i].code == 108 and a.list[i].parameters[0][0,4] == "MOVE"
        # something happens here
          substrings=a.list[i].parameters[0].split(' ')
          x=substrings[1].to_i
          y=substrings[2].to_i
          a.moveto(x,y)
        end
      end
    end
  end
end

and then call it with $scene.move_events_with_comments from an event.

Depending on how many events you want to use it for you could consider putting the values in variables, to be used after.

For example, if you know that only one event will have the comment, you could have:

Code:

class Scene_Map
  def move_events_with_comments
    for a in $game_map.events.values
      next if a.list == nil
      for i in 0...a.list.size
        if a.list[i].code == 108 and a.list[i].parameters[0][0,4] == "MOVE"
        # something happens here
          substrings=a.list[i].parameters[0].split(' ')
          $game_variables[30]=substrings[1].to_i
          $game_variables[31]=substrings[2].to_i
        end
      end
    end
  end
end
