New Particle Engine

[arev]

@Helladen: yeah, as most of particle systems :D You just can't overdo it

@psykedeath: thanks I might make a small tutorial on this, however I'm thinking of rebuilding the script a little, putting those math things inside. And the keys are assigned in one of the events.

Hey arevulopapo, I have an idea, that if you occasionally has been some packages with new particles, because by that I see that your script has a huge variety to create new effects.

Great script, and there is a hint!

 

[HunterDVincent]

i would like to see if i can get these particles and stuff into a battle like spells and such, thats would be pretty awsome you should try and make a script to do that sometime arevulopapo

Kinda laggy, but thats just my computer
Great job

Nice script :D.
Here is a suggestion, make particles actual animations. To do this you can do:

Animation_List = {}
Animation_List[animation_id] = particle_type

animation_id = animation id from the Database

Then, of course, you would need to edit RPG::Sprite's animation method.

Something like:

def animation(animation, hit)
  if Particle.Animation_List.include?(animation.id)
    [Particle Code On Character]
  else
    [default code] 
  end
end

Uses:
- ABS systems.
- Battle Systems.
- Just any map animations.

I think it would be even easier to use this way anyways.

But looking at the way you did the script, you would need to adjust a bit more. I would do it but its your script, I don't like editing other people's scripts...

Thanks for suggestions Unforunatelly I don't quite understand what I'd need to do for this ^^ Would be nice if you could elaborate on this a little more

Powerful script, how can i put in the event script that the particle effect appear on the same event? (Without using the event ID)

 

[arev]

Actually you need to put the ID in the command. But you can obtain it by a simple command without knowing the actuall event id.

id = get_character(0).id

Then just use the 'id' variable (without the quotes) instead of a number.

 

[Malvaro]

Do i need to add that line somewhere in the script code or just use it in the event?. Because I use it in the event just like this...

script: id = get_character(0).id
script: $scene.effect(id,'fire','event',0,0)

and gave me an error message (undefined method 'get_character' for #<game_event... etc)

 

[arev]

Seems like you used it in the Set Move Route command. You nee to use the last command on the thid page of standard event commands - "Script..."

 

[Malvaro]

I see... it works perfect now

Thank you!

Sure.

When an animations is shown on a Game_Character instance, ie $game_player, their "animation_id" is set to the animation's id. Like so:

$game_player.animation_id = 0 # means no animation

The Sprite_Character method checks if there is a current animation by:

    # Animation
    if @character.animation_id != 0
      animation = $data_animations[@character.animation_id]
      animation(animation, true)
      @character.animation_id = 0
    end

You don't need to worry about that really, its just to get you familiar with the system.

First of all, you would need a way for you to tell if an animation id is a particle animation id. To do this, you can add a hash to your script:

Animation_List = {}
Animation_List[animation_id] = [effect, lock, x, y]

You want that somewhere you can easily access, like a module(I'll use a module named Particle for this example).

Next you want to edit the place where the animation is executed, which is in RPG::Sprite:

    def animation(animation, hit)
      dispose_animation
      @_animation = animation
      return if @_animation == nil
      @_animation_hit = hit
      @_animation_duration = @_animation.frame_max
      animation_name = @_animation.animation_name
      animation_hue = @_animation.animation_hue
      bitmap = RPG::Cache.animation(animation_name, animation_hue)
      if @@_reference_count.include?(bitmap)
        @@_reference_count[bitmap] += 1
      else
        @@_reference_count[bitmap] = 1
      end
      @_animation_sprites = []
      if @_animation.position != 3 or not @@_animations.include?(animation)
        for i in 0..15
          sprite = ::Sprite.new(self.viewport)
          sprite.bitmap = bitmap
          sprite.visible = false
          @_animation_sprites.push(sprite)
        end
        unless @@_animations.include?(animation)
          @@_animations.push(animation)
        end
      end
      update_animation
    end

You want to edit that to check if the animation ID is actually a particle effect:

   def animation(animation, hit)
      dispose_animation
      if Particle::Animation_List.has_key(animation.id)
        
      else
        @_animation = animation
        return if @_animation == nil
        @_animation_hit = hit
        @_animation_duration = @_animation.frame_max
        animation_name = @_animation.animation_name
        animation_hue = @_animation.animation_hue
        bitmap = RPG::Cache.animation(animation_name, animation_hue)
        if @@_reference_count.include?(bitmap)
          @@_reference_count[bitmap] += 1
        else
          @@_reference_count[bitmap] = 1
        end
        @_animation_sprites = []
        if @_animation.position != 3 or not @@_animations.include?(animation)
          for i in 0..15
            sprite = ::Sprite.new(self.viewport)
            sprite.bitmap = bitmap
            sprite.visible = false
            @_animation_sprites.push(sprite)
          end
          unless @@_animations.include?(animation)
            @@_animations.push(animation)
          end
        end
        update_animation
      end
    end

Once you do that, you make sure the current scene is Scene_Map, since you made your script to use Scene_Map(bad choice :-p)

   def animation(animation, hit)
      dispose_animation
      if Particle::Animation_List.has_key(animation.id) 
        if $scene.is_a?(Scene_Map)
          a = Animation_List[animation.id]
          $scene.add_effect(@character.id,a[0],a[1],a[2],a[3])
        end
      else
        @_animation = animation
        return if @_animation == nil
        @_animation_hit = hit
        @_animation_duration = @_animation.frame_max
        animation_name = @_animation.animation_name
        animation_hue = @_animation.animation_hue
        bitmap = RPG::Cache.animation(animation_name, animation_hue)
        if @@_reference_count.include?(bitmap)
          @@_reference_count[bitmap] += 1
        else
          @@_reference_count[bitmap] = 1
        end
        @_animation_sprites = []
        if @_animation.position != 3 or not @@_animations.include?(animation)
          for i in 0..15
            sprite = ::Sprite.new(self.viewport)
            sprite.bitmap = bitmap
            sprite.visible = false
            @_animation_sprites.push(sprite)
          end
          unless @@_animations.include?(animation)
            @@_animations.push(animation)
          end
        end
        update_animation
      end
    end

Also add this:

class Game_Character
    attr_accessor :id
    alias av_particle_game_char_int initialize
    def initialize
      @id = -1
      av_particle_game_char_int
    end
end

Thats about all I see from your script.

Thanks a lot, it's readable now But is there anything else this would do, except launching the animation from the event command?
And Scene_Map was chosen because of the spriteset_map, that I wanted to put the particles into. As far as I know they have to be in the same viewport as the tilemap and the characters for the Z coordinate to have some effect, don't they? So are there any more advantages than the one I mentioned?
And thanks for all that again. It's really educating ; )

 

[Mr.Mo]

Besides launching the particles from an event command for easy use, it would also make ABS systems look hot :p.

I would think about using it in CBS systems as well but you would need to edit Spriteset_Battle.

Also, you could edit your Particle Engine to make particle effects last for a period of time(in frames), which would be useful for event command by animation.

Its all easy stuff I'm sure you can do it

I don't have a problem with the choice of Scene_Map that much really. I would have done something entirely different, but thats just me(and still use the same viewport). It doesn't matter much.

 

[arev]

Mkay, I'll work on it a bit, but probably I'll release another version before. Thx

 

[Khoa]

I cant' down load it, (><)
please upload http://mihd.net/
thank you

I'm sorry arevulopapo if you didn't want it there. =(

 

[arev]

It's okay. I didn't even notice Khoa's request, so thank you ; )

 

[Hellladen]

@Helladen: yeah, as most of particle systems :D You just can't overdo it

Sorry for the long reply, but yeah I knew that.
Though this actually quite nice. Once I checked out like 2-3
other particle system, this one seems to be the best.
Good job, hopefully you can add more to this eventually.
I am going to be using this on my new game. :D

 

[Khoa]

Thank Hyde very much, thank you for your help (^^)
