Haxelib-based OpenFL sample projects

OpenFL Samples

Haxelib-based samples are located here, check out https://github.com/openfl/openfl-samples-haxe for NPM-based samples.

A collection of sample projects illustrating different OpenFL features.

Installation

haxelib install openfl
haxelib run openfl setup

The openfl-samples library will be installed automatically. If you need to install it alone, you can use the following command:

haxelib install openfl-samples

Listing Samples

You can browse the project directory, but it is generally simpler to use the following command to list available OpenFL samples:

openfl create

Creating Samples

Once you find a sample you would like to create, you can generate a copy using the "create" command:

openfl create PiratePig

This creates a copy in the current directory, but you can also specify an output directory if you prefer:

openfl create DisplayingABitmap BitmapTest

Development Builds

Clone the openfl-samples repository:

git clone https://github.com/openfl/openfl-samples

Tell haxelib where your development copy of openfl-samples is installed:

haxelib dev openfl-samples openfl-samples

To return to release builds:

haxelib dev openfl-samples

openfl-samples's Issues

Can't build flash version of HerokuShaders

There compile error is:

openfl build flash
Source/Main.hx:25: characters 9-49 : Class not found : GLUniformLocation

Please let me know if it's a configuration issue on my end.

Thanks,

SimpleOpenGLView: silent crash on neko

SimpleOpenGLView immediately crashes for me on startup: "SimpleOpenGLView.exe doesn't work anymore". There's no stacktrace. The Visual Studio Debugger claims the crash originates in neko.dll:

Seems to work fine on windows. Latest OpenFL / Lime versions from haxelib.

Can we run live/hot reload dev mode for HTML5 ?

Update "AddingDOMElements" sample for DOMElement

Need to update the sample to use the new DOMElement type instead of DOMSprite

Adding BunnyMark

I have a version of https://github.com/jgranick/nme-bunnymark that uses the standard of these samples if interested in adding to this repo. Let me know if you want me to make a PR, or just close this issue if you don't.

Add basic install instructions to README.md for convenience.

Helpful to some.

OpenGLView is not initialised on HerokuShaders for html5

With the supplied project.xml build file, the HerokuShaders example does not work on html5 - the call to OpenGLView.isSupported returns false.

I first assumed that I'd need the -D webgl flag, but that didn't work either - OpenGLView.isSupported will return true but the webgl context is not initialised (at runtime lime_graphics_opengl_GL.context is null). So I had to investigate the code in OpenGLView.

It seems to need the -D dom flag setting to work properly on html5. But it's not clear if -D webgl is also needed or of any benefit.

Adding <haxeflag name"-D dom" if="html5" /> to project.xml fixes the issue.

SimpleOpenGLView sample -- "Invalid constructor arguments for Float32Array"

It looks like something has changed recently and now the SimpleOpenGLView sample isn't running for me. It dies in renderView with the message

Error : Invalid constructor arguments for Float32Array

I think this might be a pretty recent change. I haven't worked out how this can be fixed.

Class not found : UInt

When I try executing haxe build linux for "HandlingMouseEvents", I get the error:

/usr/share/haxe/lib/openfl/2,1,3/openfl/geom/Matrix3D.hx:174: lines 174-186 : Class not found : UInt

What is happening?

Custom fonts example doesn't work on HTML5

Custom fonts example doesn't work on HTML5. I am using Openfl compiler in IntelliJ, the Flash output looks ok but the HTML5 output is wired - it applies some default kind of sans font to letters but serif to numbers. Here is the project with my compiled outputs: https://dl.dropboxusercontent.com/u/2731147/CustomFont.zip

And here is a screenshot of the HTML5 vs Flash target: https://dl.dropboxusercontent.com/u/2731147/Screen%20Shot%202014-08-11%20at%2009.29.16.png

Uneccesary <haxelib name="actuate" /> nodes in some project.xml files.

Looks like an uneccesary nod in the project.xml files of:

AddingText
DisplayingABitmap
HandlingKeyboardEvents
HerokuShaders
SimpleOpenGLView

All the examples running on iOS 7.1 that use images are either crashing or showing black screens

Not too much to add. Everything used to work just fine, now for some reason, I don't know if it's because of iOS 7.1 or because of an updated OpenFL version, none of the samples are working for me.

Heroku example fails to generate working hxml

If you try to run the hxml generated by "openfl display" you get:
/usr/lib/haxe/lib/openfl/1,0,5/openfl/display/DirectRenderer.hx:8: lines 8-13 : Class not found : DisplayObject

This was happening for all of the targets.

To recreate:

openfl create HerokuShaders
cd HerokuShaders
openfl update html5
openfl display html5 > test.hxml
haxe test.hxml

HerokuShaders only shows the first fragment shader, black screen afterwards

It seems like the demo is supposed to step through the different fragment shaders, however, I only get a black screen on both neko and windows after the first shader is done.

Latest OpenFL / Lime versions from haxelib.

SimpleBox2D compilation fails on neko

See issue openfl/box2d#5

Running Samples

Can someone please add a 'Running Samples' section?
The required incantations are not obvious to me..
$ openfl create HelloTriangle
$ ls HelloTriangle/
HelloTriangle.hxproj project.xml Source
$ openfl run HelloTriangle
Error: You must have a "project.xml" file or specify another valid project file when using the 'run' command
Thanks.

Bug: SimpleOpenGLView

This happens when build the SimpleOpenGLView sample

Source/Main.hx:121: characters 25-45 : flash.geom.#Matrix3D has no field createOrtho (Suggestion: createOrth)

HTML5 BunnyMark blank screen

Hello!

Windows 10 64
Openfl 6.0.0
Haxe 3.4.2 (git build master @ 890f8c7)
Firefox 54.0.1/Chrome 59.0.3071.115
Debug/Release mode - same result

I got white screen with FPS-meter and no bunnies at start up or when clicked on stage.
CPP-version is working.

Adding trace() breaks flash version of PiratePig

I'm not sure what is the cause, but try to add trace('something') or Lib.trace('something') somewhere in PiratePig, and you will get WSOD, when targeting flash. Game will compile but won't start. This is important as this is a sample of the game, that will be inspiring many people, and they will discover this problem firstly in their own projects (like me). I'm not sure if this is problem with HaXe or something with architecture of this sample.

DrawingShapes: Could not find asset path "Assets"

Won't work with Openfl 2.1

I just updated the openfl to 2.1 (and lime to 2.0.0 alpha, as it was written: http://www.openfl.org/blog/2014/10/14/openfl-2-1/), but it won't work with the SimpleOpenglView sample. It says:

Source/Main.hx:214: characters 2-20 : Class<lime.graphics.opengl.GL> has no field uniformMatrix3D (Suggestions: uniformMatrix3fv, uniformMatrix4fv, uniformMatrix2fv)

[C#] After pausing sound, I can't click background anymore in PlayingSound example on cs

Actuate.tween (background, fadeOut, { alpha: 0.1 }); in line 60 somehow make background Sprite unclickable. Sprite fadeouts correctly, but becomes unclickable after finishing fadeout. background.alpha = 0.1; does not make background unclickable, so there might be some issue in actuate library.

As of lime 3.4.1 sound does not play on cs, because of a bug in AudioBuffer.fromFile, but I think this should be discussed in other issues.

openfl-samples/features/media/PlayingSound/Source/Main.hx

Line 60 in 66bd07b

Actuate.tween (background, fadeOut, { alpha: 0.1 });

Online samples

This is more of a question than an issue, but what do think about putting all the samples online? Either in a gh-pages branch in this repo, or on www.openfl.org?

CreatingCustomEvents: Could not find asset path "Assets"

A test with openfl create CreatingCustomEvents on openfl-samples 3.3.1 seems to break with missing assets.

lime samples showing for openfl

The following shows SimpleOpenGL as an openfl sample, even though I think it's a lime sample along with the bottom 3 in the list:

$ lime create openfl
You must specify a template when using the 'create' command.

 Usage: lime create library:project "com.package.name" "Company Name"
 Usage: lime create library:sample "OutputDirectory"
 Usage: lime create extension "ExtensionName"

 Available Samples: openfl

  - PiratePig
  - ActuateExample
  - PlayingSound
  - HandlingKeyboardEvents
  - HerokuShaders
  - SimpleOpenGLView
  - HandlingMouseEvents
  - DisplayingABitmap
  - AddingText
  - AddingAnimation
  - SimpleBox2D
  - HerokuShaders
  - SimpleOpenGL
  - SimpleAudioExample

Yet I can't build it:

This is misleading and confusing if it is not an openfl sample.

BunnyMark memory leak?

Memory usage does not stop growing after launching BunnyMark example.

"layout" is not listed as a dependency in haxelib.json

The "layout" library is used in "SimpleSWFLayout", but is not included in haxelib.json as a dependency.
