Referencing a Single Frame of an Animation

[Robert-Character Creator]

(Posting it here as I think it's a safe bet.)

Hello! I'm attempting to tie in a sound effect to an animation I've made, so it plays during the corresponding frame. This is possible in the database, where you can set up these animations to have sound effects included. So, how would I go about doing this for, say, a walking animation?

The frames of a Character/Event model's animation are known as "pattern" in Ace's code. So inside the class, you could reference it with:

@pattern

So you can use that inside the class, or outside the class (that is, anywhere else in the code or the game) you would use xxx.pattern where xxx is the reference to a Character/Event, such as $game_player.pattern or $game_map.events[21].pattern

I believe that Pattern is not zero-indexed and the three patterns (frames) of a model will be numbered as 1, 2, and 3.

As far as playing a certain SE whenever an event hits a certain frame of their pattern, I suppose you could either run a parallel event (or add a method to Game_Map's update method) to continually check whether a certain event is currently displaying in a specific pattern (frame). Or, you could do a search for where pattern is already being manipulated in Ace's default code, and add in a SE there.

@Wavelength To get the format right, I suggest you use the 'Code' option from the Insert icon and put it in there, as that is the only way of preventing the forum software from auto formatting.

Thanks for the tip, @Kes! Edited my post accordingly to use the code formatting, to prevent the @ sign from creating a member tag.

Thank you both! I'm going to alias the code for when the player walks to add a sound effect for a footstep, and cannibalize some code from another script to variate the pitch so it's not the same sound over and over. Is there a way to check the file name of the spritesheet, while we're at it?

Edit: I think I'm doing this wrong. I'm just doing an if branch right now to test out the syntax, so I put:

alias game_characterbase_move_straight_cxj_fm move_straight
  def move_straight(d, turn_ok = true)
    if $game_map.free_movement_enabled?
      if $game_map.events[-1].@pattern == 2
      pixelstep = CXJ::FREE_MOVEMENT::PIXELS_PER_STEP / 32.0
      @move_poll+= [[d, turn_ok]] * (distance_per_frame / pixelstep).ceil
      end
    else
      game_characterbase_move_straight_cxj_fm(d, turn_ok)
    end
  end

I also tried:

 alias game_characterbase_move_straight_cxj_fm move_straight
  def move_straight(d, turn_ok = true)
    if $game_map.free_movement_enabled?
      if $game_map.events[-1].@pattern(2) == true
      pixelstep = CXJ::FREE_MOVEMENT::PIXELS_PER_STEP / 32.0
      @move_poll+= [[d, turn_ok]] * (distance_per_frame / pixelstep).ceil
      end
    else
      game_characterbase_move_straight_cxj_fm(d, turn_ok)
    end
  end

Edit 2: No matter how I type it, 'literallyanything'.pattern results in a NoMethodError for pattern.

You are editing a game_characterbase method, so you don't need to use $game_map.events to get the event. this is the event (assuming you are wanting to check the same event that's doing the moving).

So just use

@pattern

I think it actually is zero-indexed, and it moves in 0-1-2-1-0-1-2... but I'm at work & don't have access to my computer to check. The middle one is the 'idle' sprite.

Hmm, I also have a script that modifies the number of frames in a sprite, and I use 8. Do you think it would work the same way, but with 1-8, or 0-7, as the case may be?

 

[Shaz]

yes

Short and simple. I like it.
