How to use

###Setup and Install for Android:

1. Install Android NDK first.
2. Install Android SDK then Eclipse and ADT OR, Android Studio
3. cd <your project dir> then run /path/to/your/android-ndk-r9/ndk-build to compile libejecta.so and libJavaScriptCore.so
4. Open in your favourite IDE and build.

Note for Windows users:-

Current branches no longer work on Windows after the OpenGLES update. Please use the older release https://github.com/aogilvie/Ejecta-X/releases/tag/v0.9.9-original

Sample

For an example application in the sample folder, name Ejecta-X.apk.

For XHR, remember to add <uses-permission android:name="android.permission.INTERNET"/> to the Android Manifest.

Native Events

Register for Java Events

Set an event listener on your activity as follows;

((EjectaGLSurfaceView)mGLView).setEjectaEventListener(new EjectaRenderer.EjectaEventListener() {
    @Override
    public void onCanvasCreated() {
        
	}
});

Native APIs

loadJavaScriptFile(String filename)

Will load a JavaScript file into Ejecta-X. File should be relative from assets/build/<filename>.

For example to load a file at assets/build/loadme.js would be;

((EjectaGLSurfaceView)mGLView).loadJavaScriptFile("loadme.js")

ejecta-x's Issues

Implement WebGL context

Ref: https://www.khronos.org/registry/webgl/specs/1.0/

Amazing Project

Are you planning to keep it up to date with Ejecta-master ?

Alternative for copying files to cache

Alternative for copying files to cache

Currently all assets are copied to cache to be loaded into the canvas. We want to read the assets directly through the Android Asset Manager.

Implement Audio API

Ref: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/audio

Canvas is automatically cleared

The sample index.js has the following code to clear the canvas

// Clear the screen - note that .globalAlpha is still honored,
// so this will only "darken" the sceen a bit

ctx.globalCompositeOperation = 'source-over';
ctx.fillRect(0,0,w,h);

But commenting ctx.fillRect(0,0,w,h) so that it is not called still results in the canvas being blanked during the interval call. I guess there is some native clear screen happening.

can't run the default project

EJClassLoader Refactor

EJClassLoader

Remove code from the EJBinding Class to create the EJClassLoader Class that is used in Ejecta for iOS

Are touch events implemented ?

Hi,

Are touch events already implemented ?
When I try (on Android) to add any, I get a:

EJBindingTouchInput is NULL ...
followed by a
new Ejecta.TouchInput() is undefined and -obviously- is not a constructor :).

Thank you in advance for your answer.

Phaser/Pixi integration issue

Did anyone have any luck integrating Phaser or Pixi with Ejecta-X? Seems that I have pretty much a problem here - every time I run my game on the device I get a black screen. What I did to prepare application for deployment (using Ejecta-X version 0.2.0):

I. Put all JavaScript and asset files (eg. images) in assets/build directory
II. Add all JavaScript files to onCanvasCreated method. Eg:

[...]
            public void onCanvasCreated() {
                Log.d("ejecta", "Event: Canvas was created");
                ((EjectaGLSurfaceView)mGLView).loadJavaScriptFile("ejecta.js");
                // General shiet
                ((EjectaGLSurfaceView)mGLView).loadJavaScriptFile("vendor/phaser/build/phaser.js");
                ((EjectaGLSurfaceView)mGLView).loadJavaScriptFile("vendor/lodash.min.js");
                ((EjectaGLSurfaceView)mGLView).loadJavaScriptFile("index.js");
                // Controllers
                ((EjectaGLSurfaceView)mGLView).loadJavaScriptFile("app/controller/GameInputController.js");
                ((EjectaGLSurfaceView)mGLView).loadJavaScriptFile("app/controller/MeteorSpawnController.js");
                ((EjectaGLSurfaceView)mGLView).loadJavaScriptFile("app/controller/FoodSpawnController.js");
[...]

III. Build the application

Index.js in my example contains standard Phaser booting (with stripped window.onload = ...):

'use strict';

var GameSpace = {};

    GameSpace.game = new Phaser.Game(window.innerWidth, window.innerHeight, Phaser.AUTO);
    GameSpace.game.state.add('Boot', GameSpace.BootState);
    GameSpace.game.state.add('Preload', GameSpace.PreloadState);
    GameSpace.game.state.add('Menu', GameSpace.MenuState);
    GameSpace.game.state.add('Game', GameSpace.GameState);

    GameSpace.game.state.start('Boot');

I'm using Phaser version 1.1.3 (issue occurs also for 2.0.3).

It's worth mentioning that the sample provided with Ejecta-X works fine for me.

Any idea would be greatly appreciated. Cheers.

But the canvas in Ejecta for IOS have the style properties.THX

compile Objective C ?

Also I noticed that GCC 4.6 can compile objective C. So it should be possible to compile the source code if the missing iOS bits are added in.

Three.js support

Does Ejecta-X support Three.js?

I'm trying to build a Cordova application for Android and iOS using wizCanvas v3.3 (https://github.com/Wizcorp/phonegap-plugin-wizCanvas) but loading the Ejecta canvas fails to load on Android when three.js is included.

I've got as far as identifying two errors in the console when loading three.js r66.

1. Float32Array creation fails (three.js#L4009 and others). Got around this by using typedarray.js polyfill from https://github.com/inexorabletash/polyfill.
2. Fails to get webgl context in initGL() call (three.js#L26704). _gl variable returns undefined.

Thanks for any help!

Missing compiled libraries

Hello,

I've been testing the libraries and I was able to add them to my project and compile them with the NDK.

As the NDK's documentation suggests, after running the "ndk-build" script it should:

The build tools copy the stripped, shared libraries needed by your application to the proper location in the application's project directory.

But, after I have executed the script, compiled my project, and ran my project on my device, I get the following error:

java.lang.UnsatisfiedLinkError: Couldn't load JavaScriptCore from loader dalvik.system.PathClassLoader[dexPath=/data/app/com.impactjs.ejecta.sample-2.apk,libraryPath=/data/app-lib/com.impactjs.ejecta.sample-2]: findLibrary returned null

I also built the android project that is at the branch, doing the same process with the NDK first, then execute the project and I get the same error.

I would appreciate any help towards this.

Best regards.

Collaboration

My company wants to help advancing Ejecta-X, by funding some of your work, and getting some features that our important to us implemented in return.
Would that kind of an collaboration be interesting to you?

Android Studio Refactor

Android Studio Refactor

Android folder structuring is different from Eclipse in Android Studio. Currently Android Studio is still in Beta, but once a major release is announced we will refactor the project to use Gradle build system and to compile the NDK libs.

How do I debug craches in .so's

Hey. I've been trying to use my game engine with EjectaX which currently works in Ejecta. When I load my game, I get a native crash that happens down in one of the .so libraries. I need to be able to debug and dig a little deeper to see what is happening so I can fix the issues, with either my JS or with EjectaX. What is the best way to move forward.

Thanks,

Text not rendering on Canvas

Hi,

I'm trying the following code. All drawing ops like fillRect, beizerCurveTo, quadraticCurveTo etc works fine. But unable to render any text on the canvas. Am I missing something ?

var context =canvas.getContext("2d");
context.fillStyle = "blue";
context.font = "16px LiberationMono-Regular.ttf";
context.fillRect(25,25,100,100);
context.clearRect(45,45,60,60);
context.strokeRect(50,50,50,50);
context.fillStyle = "cyan";

context.fillText("Hello World", 45, 45);

Assistance with the WebGL implementation?

Hey, I'm just wondering what stage you got to with the WebGL implementation in the 'next' branch, and whether you need some assistance.

Device dependent buffers

Device dependent buffers

Plan: change EGL config setup and adapt Ejecta-X to support the different possible configurations in order to fix graphic glitches on some devices.

Ejecta-X or Tephra

Great project. ..

Can you detail a little bit about the difference between Ejecta-X and Tephra ?

Thanks!

Is it possible to call native Java code from the JS code?

And vice versa?

Multiple Hardware Buffers

Multiple Hardware Buffers

Flickering issues are caused on some devices because some Android device hardware contains 2 buffers, some have 3.

FATAL EXCEPTION: GLThread when building sample project

This is the same issue (almost) as #31. Opening a new one since author of the last one didn't provide any answer.

Log:

Also, what I did to "install" Ejecta:

1. Cloned the repository
2. Ran ndk-build in project/android
3. Imported project into Eclipse
4. Used "run" to build and emulate

Also checked on my mobile device. Any help would be greatly appreciated, since I'm totally, absolutely stuck.

Old implementation of javaScriptCore - no .bind function

The JavaScriptCore library used in the project is very old - it doesn't even support the .bind function. This should be updated as it doesn't allow to create a ejecta<->ejecta-x common build environment/sources.

P.s. for now we can use a polyfill https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Function/bind

Ejecta-X Repository

@3dseals

我們公司有持續為Ejecta-X專案作更新和改善。
我們的目標是把它做到跟iOS Ejecta一樣。

不知道可不可以:

1. 給我的帳戶:aogilvie merge(合併)的權限?
2. 如果你已沒有維護這個專案, 我們可否把”Repository的所有權”轉給用戶:Wizcorp?

謝謝。 / Thanks! 🚀
