fengine's Issues

SERIOUS bug when changing states...

Some Seriously annoying and weird bug when trying to change the states from within an event listener function.

Update "width/height" of the parent SceneNode2D object

Properly update the width/height fields of the parent SceneNode2D object depending on its children.

Implement simple memory pooling

Implement very simple memory pools (Actor pools actually) to facilitate the reuse of Actor objects.

Android : View goes Blank when resuming game

On android, the game goes blank {only the physics debug draw continues to work} when the game is restored after being paused... very very weird. Need to investigate...

ProcessScheduler is crashing

The Update() method in the ProcessScheduler needs to be rewritten. The processes that are active need to be checked Separately from the processes that are already terminated.

Currently everything is being processed in one big switch statement. If any process attaches a child and deletes itself, the iterator updates to incorrect value resulting in a Crash.

Return smart pointer from StateManager's Get function

The StateManager's Get() function should return a smart pointer object instead of a naked pointer. i.e:

Change:
Statemanager * Get()

To:
StateManagerPtr Get();

iOS: libPng failed to compile on actual device

the libPng filed to compile on the actual device (arm7 architecture).

Error:

Undefined symbols for architecture armv7:
"_png_init_filter_functions_neon", referenced from:
_png_init_filter_functions in libFEngine.a(pngrutil.o)

Ugly hack for ContentScaleFactor in SpriteNode's PreRender function

The entire scene graph and matrix stack has to be revised. Very ugly hack implemented in SpriteNode's PreRender function. This is to ensure that ONLY the leaf nodes like sprite get multiplied by CSF.

Side effect of this is that if I need to scale leaf node, i need to put it "inside" an empty container.

Android: OpenGL goes blank after the game is resumed

If the game is resumed from the background, the OpenGL surface goes totally black. As it appears the EGLContext is being destroyed when the app goes into background.

Android Fastdelegate Compilation error

The NDK gives errors regarding "memcpy" not found.

Sometimes: Failed to load systemConfig xml file

Few of the times tinyXML failed to load SystemConfig.xml.

Implement Component Factory (View component)

For now, Implement component factory that returns a fully initialised view component --> It should be able to accept xml file and return a VIEW component based on that description.

When this is implemented, extend the component factory and then start working on the Actor factory.

Android: Implement State saving

The activity is destroyed and then re-created as it goes into background and then to foreground, or if the orientation changes. Need to implement state saving in Android which should save the current state of the game.

Implement Data saving/retrieving capabilities

Write classes that would facilitate in saving and retrieving raw data from storage space.

Android: CRASH when displaying Chatboost ads

Whenever the ChartBoost ads are requested to be displayed using the generic FEngine API, game crashes.

gApp->GetAds()->ShowInterstitial();

Implement Actor management system

Implement actor management system. Integrate the views with it as well.

GameEngine: implement state saving mechanisms

Please implement efficient mechanisms for saving and loading current game state. This should be very detailed, e.g: even the position/color/angle of individual particles should be recreated upon restore.

Particle Generator: please Implement

Implement particle generator, preferably having emitters, attractors and deflectors.

Implement Chartboost ads

Implement Chartboost ads on both iOS and Android.

Fix Memory leaks

There are memory leaks and unwanted allocations all over the place. Please fix these.

Port Engine to Android

Weak_ptr to Actor in all Components

Instead of storing a strong pointer to actor, just store a weak pointer to the actor in ALL of the components so that it doesn't result in a memory leak as it is happening right now :S

Implement Input Controller

Implement Input Controller. In initial versions it should respond to touch events.

Rename StubAds.h to AdsStub.h

Be consistent and rename:

StubAds.h to AdsStub.h

Through testing of ALL individual Engine sub-systems

Perform very through testing of ALL of the engine sub-systems individually!
Testing will include:

• Stress testing
• Boundary conditions
• Performance testing
• Memory consumption
• Resource consumption
  Etc

Implement Physics Controller

Well, this is not going to be a realistic physics at all. Just some candies falling with constant speed. Also need to implement collision detection specially keeping in view the "tunnelling" since candies will be moving fast.

Possible Memory Leak in PhysicsFactory

Possible Memory is leaking in PhysicsFactory specially while creating fixture shapes.

Optimize Event Dispatcher

The Dispatch function is performing poorly as compared to trigger event. Need to optimise it.

Implement Font system

Implement Bitmap atlas, Font cache, multi language support etc. Try to be as simple as possible, but no simpler.

Android Box2D Compilation error

The NDK gives errors regarding "memcpy" not found in various files.

Make ActorComponents loosely coupled

Currently the ActorComponents are very very tightly coupled. Decouple them by using event manager. Also a huge army of header files is included on top of almost every source. Try to improve that as well.

Implement Update() for Scene Graph 2D

Implement the Update() function for 2D scene graph.

Add facility to create new Objects without XML files.

Right now the factory methods are hiding all the details, they read in XML file and create a corresponding object {view or actor etc}. But reading XML is SLOW. The Engine must provide EASY facilities to create new objects from the code.

The Engine also should provide mechanisms to clone existing objects from memory {for efficient creation}.

Implement Visibility function in SceneNode2D

Please implement IsVisible function in SceneNode2D. This will optimise stuff a LOT by really minimising OpenGL draw calls.

Implement Shearing using Matrix transforms

Implement Shearing using Matrix transforms.

Improve Factories

Currently factories may be a bit of mess. Clean then whenever possible.

Fix the view construction process

Right now the view factory FAILS to create views within views. Need to fix that ASAP.

CRASH: EventDispatcher (removing listener from within a listener)

Whenever an even occurs it calls appropriate listener function. Now IF a listener (specially of the same event) is removed from WITHIN the SAME initially called listener, EventDispatcher will crash (because it never got to update the listenerMap within the same loop)

Example:

void MainMenu::TouchDownListener (EventPtr e)
{
...........
EventDispatcher::Get()->RemoveListener( eventID, TouchDownListener);
............
}

Possible solutions:

1. Never delete a listener from within another listener SPECIALLY having the same EventID. Mark the listener as "ready for deletion" and then erase it from somewhere else such as ProcessSchedular or something

Please Find a better and Elegant solution !!!!

Touch coordinates computed in App class are incorrect

The touch coordinates computed in the App class and sent to Engine are not correct. Need to check those out!

Update() bug in SceneNode2D Abstract class

Even though the Scene Graph 2D is properly calling "Render()" for all children but it is ONLY calling "Update()" for the FIRST child. Remaining children do not get updated.
