Ruby/RGSS3 questions that don't deserve their own thread

[siChainlinks 20]

Ok, so I do that, but what is the symbol? For example, with the defaults I have, button 8 is R: how do I set R being pressed as a condition? Using :R doesn't work. Do I use :button_8 or something like that?

[Galv 1,387]

Using :R should work.

Button 8 is the button number of a gamepad. It is also 'Q' key on the keyboard (if you look on the keyboard tab)

 

EDIT: 'W' on the keyboard... oops haha.

Ah.... I see now. The symbol :R is linked to the key W in my game. Thanks for the tip! I don't know why I was looking at the game pad tab. Not thinking clearly enough.

how do I return the amount of actors in my database?

I want a variable to hold that value

[Galv 1,387]

I think in a Control Variable set to script you can use:

$data_actors.count - 1

[Tsukihime 1,489]

Note that $data_actors.count - 1 includes all of the "empty" actors as well.

 

Meaning, if your database looks like

1. Actor 1
2.
3.
4.
5. Actor 2

This would be treated as 5 actors and not 2. Edited August 26, 2013 by Tsukihime

How do I get the amount of "Alive" Battle Members? And the amount of "Alive" Enemies in the Troop?

[Galv 1,387]

$game_troop.alive_members.count

$game_party.alive_members.count

[AJNR 156]

Thanks Galv, god speed post

Hi, I'd like to get a clarification. In many scripts I see something like this

 

random_variable_name ||= random_value

or this 

 

(random_variable_name ||= random_value)[index/key] = value

For the latter example,the random_variable is an array or a hash.

 

I tried to search for documentation on ||= but couldn't find any. I think that it's a syntax tweak for a 'conditionnal assignation' but I'd like to understand the full reach/range of it.

 

So could someone explain it to me or redirect me to documentation ? (I looked in Ruby-doc.org and such but couldn't find any thing)

a ||= b

can be used instead of

a ? a : b

, which in itself is a shortened form of

if a
 a
else
 b
end

. "Give me a, but if it doesn't exist (or is false), assign it the value b."

[Riff 62]

Oh okay, thanks. So is the second one equal to 

 

random_variable        = random_value if random_variable.nil?
random_variable[index] = random_value

?

Edited September 1, 2013 by Riff

[regendo 204]

Your second example would be this:

random_variable_name = random_value unless random_variable_name
random_variable_name[index/key] = value

How would I get Kread-EX's Custom Weapon Formulas to apply to more than 1 Skill?

 

Modifying 

if item == $data_skills[1] && user.is_a?(Game_Actor) 

Into

if item == $data_skills[1, 7, 8, 9, 10] && user.is_a?(Game_Actor)

Returns an Error

 

 

 

class Game_Battler
	#--------------------------------------------------------------------------
	# â— Calculates the damage value
	#--------------------------------------------------------------------------
	alias_method(:krx_wformula_gb_mdv, :make_damage_value)
	def make_damage_value(user, item)
		if item == $data_skills[1] && user.is_a?(Game_Actor)
			user.weapons.each do |wep|
				if wep.formula != nil
					value = wep.formula_eval(user, self, $game_variables)
					value *= item_element_rate(user, item)
					value *= pdr if item.physical?
					value *= mdr if item.magical?
					value *= rec if wep.formula_recovery
					value = apply_critical(value) if @result.critical
					value = apply_variance(value, wep.formula_variance)
					value = apply_guard(value)
					@result.make_damage(value.to_i, item)
					return
				end
			end
		end
		krx_wformula_gb_mdv(user, item)
	end
end

I think you'd have to use

 

if [$data_skills[1], $data_skill[7], $data_skills[8], $data_skills[9], $data_skills[10]].include?(item) && user.is_a?(Game_Actor)

Because you can't compare a FixNum and an Array (and I think also because you can't call multiple value out of an array using that syntax)

Edited September 1, 2013 by Riff

[AJNR 156]

Thanks, it still returns an error. Perhaps I need to set up an Array of somesort before doing it?

ie.

$data_skills.array[1,7,8,9,10].include?(item) && user.is_a?(Game_Actor)

I don't know how Array works so sorry if I just created the worst line of script in the world.

 

 

 

Error: Line 158 NoMethodError occured

Undefined method '[]' for nil:NilClass

 

 

[Riff 62]

Try this one

 

if [$data_skills[1], $data_skills[7], $data_skills[8], $data_skills[9], $data_skills[10]].include?(item) && user.is_a?(Game_Actor)

I think it didn't work just because I don't know how to spell properly s-k-i-l-l-s

[Tsukihime 1,489]

One way is to say

[1,7,8,9,10].any? {|id| $data_skills[id] == item } && user.is_a?(Game_Actor)

I would suggest checking whether the user is an actor or not first before doing the loop.

Aha, yeah it works now! Thanks a bunch.

I'll try this one since it's more accessible (nevertheless thank you, Riff) And for your note, you mean to make it like this?

if user.is_a?(Game_Actor) && [1,7,8,9,10].any? {|id| $data_skills[id] == item }

And sorry to be that guy, but one last question:

How would I get a BGM to play at a position equal to a variable from an Event's Script Call?

I have this:

@> Control Variables: [0020: Multi-Use Variable] = Audio.bgm_pos

@> Script: pos = $game_variables[20]

:              : RPG::BGM.play("Song", 100, 100, pos)

But it doesn't work

What doesn't work?

Nothing related to the Weapon Formula, that works fine. Just my method of getting a BGM's Position isn't working.

[Tsukihime 1,489]

Music isn't playing? Can't find the file? Starting from the beginning? What is the value of your variable?

 

Not all formats support starting from a certain position.

Help file says only ogg and wav support it.

Edited September 1, 2013 by Tsukihime

[AJNR 156]

Sorry for the vague request, Hime.

I found this out looking through the Help Contents and all the Audio I have is converted to .Ogg Vorbis via Audacity.

The Error is:

undefined method 'play' for RPG::BGM::Class

 

The variable works because I tested it and displayed it in a textbox and it returns a number, am I using the wrong path

to get the file name?

 RPG::BGM.play("Song", 100, 100, pos)

"pos" being the variable, which is set in a line above the BGM.play

pos = $game_variables[20]

The variable is equal to the current BGM's Position so that when I switch, the new BGM starts at the position of the old BGM.

Edited September 1, 2013 by AJNR

[Galv 1,387]

Haven't tested this but I think it should look more like:

RPG::BGM.new("Song", 100, 100, pos).play

[AJNR 156]

The problem with BGM.new is that I think it automatically starts it at the Position of 0.

When I used that, it returns wrong number of arguments (4 for 3)

The extra argument being the "pos", and first three being filename, volume and pitch.
