How do I remove a GameObject from memory? If I create a space game and shoot an alien, I want that alien completely destroyed. So I do an alien.destroy. But his update method is still being called 60 times/second.
(eval):1:in `const_missing': uninitialized constant Gosu::Button (NameError)
from /usr/local/lib/ruby/gems/1.9.1/gems/chingu-0.6.8/lib/chingu/input.rb:24:in `<module:Input>'
I get this crash when trying to run any Chingu app with the latest versions
I'm getting this Exception whenever I exit a program written using Chingu or the program stops for any error.

Does this look like a gosu wrapper problem or an issue with Chingu?
One strange this is I'm having the problem on one Macbook but not another that is nearly identical.

Hello, I'm an aspiring game developer and I've chosen Gosu + Chingu libraries as my stepping stone to greater glory. I've been playing around with it for quite some time now and I really have an annoying problem with animations.
I've looked up on the animation example and tried doing the same thing, problem is I'm always getting this NoMethodError on 'next'. What might be causing this?
This is more of a question rather than a issue, but Im wondering how I can disable the enter_name gamestate once a user has already entered and successfully added their name to the remote highscores list? My idea initially was to re-assign the input that pushed the enter_name gamestate to something else, but that doesnt seem to work? Any ideas?
Also, is there a better place to ask general questions?
Thanks!
Jacob
Rect has somewhat unexpected method names. I can use GameObject#center_x, but have to use Rect#centerx (I know they mean different things in the two contexts, but what I am pointing out is that they are written differently). I assume the reason for this is that Rect is taken from Rubygame, rather than being created for Chingu specifically. Please add method_aliases so I can use methods such as Rect#center_x (which is what I expect to work). I personally don't think that renaming/deprecating, rather than just aliasing the existing methods, is worth the effort.
For Text objects, #width returns a value affected by scaling factor and #height/#size returns the absolute height, unaffected by scaling. This did confuse me for a while.
For consistency with retrofied Image, could be implemented as #width (unaffected by scaling), #height/#size (as now), #screen_width (as current #width) and #screen_height (height affected by factor). Alternatively, #width and #height being the actual screen sizes and a #font_size to find the unscaled height of the font. Not at all sure which of those two methods is best though.
The input system checks to see if a class given is directly inheriting from GameState, so if you have
self.input = { :space => StartGame }
where:
StartGame < MyGameState < Chingu::GameState
then StartGame won't get recognised as a GameState (Not a priority for me since you can just use a very simple #new to get around the issue; just something I noticed). InputDispatcher.rb line 96, anyway.
EDIT: Could also raise an exception if they pass the wrong value, rather than just ignoring it.
I don't know if I'm doing something wrong but the editor works like magic. The saved yml file is like this
but when I try to load the saved yml file it says: Couldn't create class 'Tiles::Wall'
I thought it might be an issue in the save/load objects code.
Yaml is only included when a map is loaded/saved, but assuming you stop Ocra from running as far as a window opening, it won't get included unless you manually include it. Best to always require it, even if it isn't needed. Doesn't really waste any time and removes this likelihood (and yaml is a standard library, so no worries there).
I've found that with a transitional game state set, pushing a new state then popping it back results in a new copy of the previous state being pushed onto the stack. Behold my hypothetical situation:
push_game_state OptionsMenu
pop_game_state
I can't quite pinpoint it, but it seems to be a logic error in either GameStateManager#pop_game_state
or #switch_game_state
.
Hi, I have a question about game objects. How can I know if exist objects of a particular class? That is, I need to do something like:
if Enemy.empty?
# logic if not objects of Enemy class.
end
Could create an Array with all the enemies but do not want to create variables if not necessary. I tried with "Array(Enemy).empty?" but nothing.
Another question is that when I load a font, the console throws me this:
ERROR: failed to open './resources/8_bit_madness.ttf'
ERROR: CreateFile failed
The code is this:
@ text_starge = Text.create (: text => "# {@ starge STARGE}",: size => 25,: font => "resources/8_bit_madness.ttf")
Any help?. Thanks!
I suspect most people won't be using the online high scores list, especially for smaller projects. Would it be possible to load OnlineHighScoreList
or rest-client and crack on demand?
Trying to help my cousin learn Chingu and currently the dependency on rest-client is preventing Chingu loading at all. His Ubuntu installation seems to be missing net/https.rb
and none of the advice online has actually yielded a result.
Making these dependencies optional since they're used only by a small part of the library would also be nice for people who just don't want to use them to reduce system clutter.
I tried uninstalling and re-installing various old versions of Ruby to see if I could load up some of my old video games from eight years ago. The main Gosu Gem still works okay. But I have not been able to get Chingu to install in most cases. And in the one old version of Ruby where I was able to install Chingu, I was still not able to get the games to work. In all cases I encountered loading errors. ippa, are you out there? I have posted more details on the Gosu forum. Thanks! --EagleDog
Fails because of this line 59 of traits/bounding_box.rb
width, height = self.size
replace with
width, height = self.width, self.height
and Text and normal GameObjects work
Hi, there is a way to create a .exe of my game? That is, just click on the .exe and run the game without Chingu or ruby installed. I mean something like Ocra and Gosu. I tried to create a .exe of a game in Chingu with Ocra and I get errors, not executed. And if it can, as I do? What I need?.
Hi:
/Users/piotr/.rbenv/versions/1.9.3-p0/lib/ruby/gems/1.9.1/bundler/gems/chingu-962ef58b03bc/lib/chingu/game_states/enter_name.rb:66:in `initialize': uninitialized constant Chingu::GameStates::EnterName::Color (NameError)
from /Users/piotr/Work/GitHub/apocalypse/lib/apocalypse/game_window.rb:8:in `new'
from /Users/piotr/Work/GitHub/apocalypse/lib/apocalypse/game_window.rb:8:in `initialise'
And this is the code:
require 'chingu'
module Apocalypse
class GameWindow < Chingu::Window
def initialize
super
push_game_state GameStates::EnterName.new(:callback => method(:add))
end
def add(name)
puts "User entered name #{name}"
end
end
end
I think it would be better if Chingu address the absolute namespaces in the code e.g.:
@texts[@index].color = ::Gosu::Color::RED
instead of
@texts[@index].color = Color::RED
Fix is either to scale x & y (* factor) when displayed and scale w/h (/factor) for collisions.
The following game object causes a segfault in my ruby interpreter when trying to save an instance of it to yaml
class Building < Chingu::GameObject
traits :bounding_box, :collision_detection
def initialize options
super
@image = Gosu::Image["1x1.png"]
@color = 0xff808080
end
end
occurs for 1.9.2 rc1 and rc2
I guess the issue is the dependency on Gosu. This is on Windows 7:

So I installed the DevKit (there were 2 other devkits, this seemed to be the latest and 64-bit, DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe).

There is a problem when using Parallax and Viewpoint together since Parallax is GameObject but does not have @image set and therefor the draw_relative method fails:
chingu-0.7.5/lib/chingu/game_object.rb:155:in `draw_relative': undefined method `draw_rot' for nil:NilClass (NoMethodError)
Minimal code reproducing the issue is:
class Flying < Chingu::GameState
trait :viewport
def initialize(options = {})
super
@parallax = Chingu::Parallax.create(:x => 0, :y => 0, :rotation_center => :top_left)
end
end
class Game < Chingu::Window
def initialize
switch_game_state(Flying)
end
end
Is there something wrong with my understanding or is it an issue? AFAIK it is not fixed in master branch but I am willing to consult it and commit a fix, please let me know.
thanks

Hi, I thinks that this is a minor issue, but it may help if anyone else has the same issue that I had while running the code for the example 7 with the latests released version (0.8.1).
The example makes a call to #fill_circle method, defined in Chingu::Helpers::GFX. But the 0.8.1 version doesn't have the code for that method, which makes it crash.
I just downloaded the latest version of the helper file and added to my local gem. When the newest version of the gem is released this won't be a problem anymore, I guess.
I believe the title states the problem.
rest-client was used in the source but wasn't pulled in as a dependency.
I see that chingu maps gosu's keys to nice simple symbols. But there doesn't seem to be a symbol for the semicolon or quote characters (or others I'm sure). I don't know what they would map to for gosu or if gosu takes into account those characters either.
What can I do to listen to semicolon and quote keypresses?
Hello,

For example, on a Mac command + q is common for quitting. How can I bind this to :exit?
Thanks
I'm trying to use a simple parallax in a viewport example21_sidescroller_with_edit.rb similar to, but when I walk too much parallax repeated stops, these two traits are incompatible? and tested in various ways and nothing.
At first he repetipe several times but when I move a lot of stops and the only thing left is the black background of the viewport. Any help?
Sorry for the bad English :)
Basically, this is what I'm doing:
class Nivel1 < GameState
traits :viewport
def initialize(options = {})
super
self.input = {:e => :edit}
self.viewport.game_area = [0, 0, 3000, HEIGHT]
@parallax = Chingu::Parallax.create(:x => 0, :y => 0, :rotation_center => :top_left)
@parallax.add_layer(
:image => "space.png",
:repeat_x => true,
:repeat_y => false,
:damping => 5
)
load_game_objects
@player = Player.create
end
def edit
push_game_state(GameStates::Edit.new(
:grid => [32,32], #tamaño de las rejillas en el modo editor.
:classes => [
Player,
Rocks,
Water
]))
end
def update
super
self.viewport.center_around(@player)
@parallax.camera_x, @parallax.camera_y = self.viewport.x, self.viewport.y
end
end
Basically
:holding_left,up, right. down works perfectly
but
if you try
:holding_a ( or any letter ) it will not call the method with the same name, or any name for that matters. ( but in the case of having the same method name as the input, it will complain if it's not here, which is good and as expected )
It's just not calling the action as it should, or not detecting the hold for that key...
You forgot to convert the to symbol the strings for the Gamepad buttons. :)
Hello, I am trying to pass a parameter to a gamestate and I can't find the way, and tried in the following ways:
switch_game_state(Play.new(parameter=100))
switch_game_state(Play, options={:parameter=>100})
but nothing. I have a simple class that inherits from Chingu::GameState, which has the method intialize(parameter).
Any help?
Hello,
I installed chingu trought gem install chingu, and used it without a problem. But then I decided to download the code and when I do the "require", I get the following errors:

I'm working with ruby 1.8.7 on ubuntu 11.04 64 bits. Any help is apreciated :-)
Image::autoload_dirs and Sample::autoload_dirs methods do not correctly connect to the class instance variable used to autoload assets. Instead, they return a regular class variable (@@autoload_dirs) which is always an empty array and is not the same array as the one used to load assets, so altering it has no effect.

While going through the examples, I found that on Ubuntu 14.04 the Gosu Tutorial example FPS goes from 60 to 30's/20's. The problems seems to be the on screen display of the score, once that is removed it works fine and there is not a FPS drop.
name always equals itself (timer trait)
def stop_timer(name)
@_timers.reject! { |name, start_time, end_time, block| name == name }
@_repeating_timers.reject! { |name, start_time, end_time, block| name == name }
end
Bounding boxes are one pixel too big on right and bottom side.
Width should be "left + width - 1", not "left + width".
I try the game state following the example 24, and it works great. Then I decided to use it after a previous state but then I got the following error : prueba.rb:24:in 'initialize': undefined method 'push_game_state' for nil:NilClass (NoMethodError). So it seems that the this state can only be pushed by Chingu::Window and not by any other state. The code that shows the error is:
class Game < Chingu::Window
def initialize
super(800,400,false) # leave it blank and it will be 800,600,non fullscreen
self.input = { :escape => :exit } # exits example on Escape
self.caption = "Demonstration of GameStates::EnterName"
push_game_state(Name_Select)
end
end
class Name_Select < Chingu::GameState
def initialize(options = {})
super
push_game_state(GameStates::EnterName.new(:callback => method(:got_name)))
end
def got_name(name)
puts "Got name: #{name}"
exit
end
