What am I doing wrong here?

[HarryE]

Hey guys. I'm trying to create a method that simply creates a very basic event at some co-ordinates in the current map. Here's what I have so far.

  def VoodooDoll.create_clone(x,y)

    clone = RPG::Event.new(x,y)

    clone.name = "LEON_VOODOO_CLONE"

    clone.id = $game_map.events.size + 1

    clone.pages[0] = RPG::Event::Page.new

    clone.pages[0].graphic.character_name = "Leon"

    $game_map.events[clone.id] = Game_Event.new($game_map.map_id, clone)

  end

Now I have done this all while keeping an eye on the RPG reference manual (you know, the one you get when you press 'help'), and it seems that the initialize method of RPG::Event's subclasses (ie; RPG::Event::Page, RPG::Event::Page::Condition, RPG::Event::Page::Graphic and RPG::EventCommand) take care of themselves, in that they create very basic versions of themselves, hence why they are not really addressed in my method.

Also, I have created attribute accessors for @map_id and @events.

Problem is that just nothing happens when the script is run. No errors are thrown, just nothing happens. But at the co-ordinates given when I call the script, I can't walk over that tile. It's like an event is there, just transparent. I tried also putting "Graphics/Characters/Leon.PNG" but that didn't work either. Any help? I'm not sure what I'm doing wrong, here.

So I looked into it, and the problem is quite simple. You were creating an event, but the event sprites are created when you load Scene_Map. That means a bit of a workaround is required to get it to work properly. That said, I have a demo script that makes it work. If you look at what I have below, this is what you need to do to add it to the map. I also removed an unnecessary line of code, and corrected the event id. (Size returns 1 larger than the last id in an array or array-like hash, so you don't need to add one when you use it).

  end

end

Oh, cool. That works. Though, size+1 is necessary because event ID's actually start counting from 1, not 0 like we are always taught was the practice. Silly RPGMaker... Anyway, it still all works. Thanks, man!
