Current implementation for logic nodes is missing this functionality.
My proposal is in attached files. (I did not do anything special: proposal is 
almost identical to gkKeyNode class)

This is not an issue! (just a question)
I am very interested in this project and I will like to know if gamekit 
will have continuity. (Since I did not see many changes lately...)

Currently gamekit does not read game logic data (logic bricks) from blend 
file. I have seen some code for reading physics from blend files (but is 
not fully implemented and the code does not look stable...)

I would appreciate if someone can answer this question!!!

Thanks!

What steps will reproduce the problem?
1. ./GameKit clubsilo_packed.blend(from gamekit directory)
2. doesnt load
3.

What is the expected output? What do you see instead?
I expected it to load other files than just Animationbaked.blend. I delete
that file trying to get it to work.  Could you post 1 or 2 lines on usage?

What version of the product are you using? On what operating system?
Ubuntu9.10 64

Please provide any additional information below.

Right now, the Mac OSX version of gamekit runs in the background without user 
input. It is likely due to .NIB files not being included in the build system.

See http://www.cmake.org/pipermail/cmake/2008-October/024920.html

See the hinge.blend and chain_demo_1.0.blend in the gamekit folder

Topic says enough.

For the following "test13" function: the gkMathNode::update method is 
called just one time (only for the first tick). If I am not wrong it should 
be called for every tick since "pMathNode" does not have direct dependency 
with "pKeyNode". Instead of that "pMathNode" is blocked after the first 
tick because has an input socket linked to "pMouseNode" and this last one 
is indirectly blocked because "pKeyNode".

I could solve this issue in two ways: 
1) Creating another mouse node for the math node. 
 I do not like this solution because in a graph, nodes (same instance) can 
be reused. (And this looks to me as a hard-restriction...)
2) Changing gkLogicTree::findSubNodeForward method to not include input 
sockets relations...

Am I missing something?



void test13(gkSceneObject* pScene)
{
    gkCameraObject* pCamera = pScene->getMainCamera();

    gkLogicTree* pTree = gkLogicManager::getSingleton().create();

    gkLogicNode* pMouseNode = pTree->createNode(NT_MOUSE);

    gkLogicNode* pMathNode = pTree->createNode(NT_MATH);

    pMathNode->getInputSocket(0)->link(pMouseNode->getOutputSocket(1));
    pMathNode->getInputSocket(1)->link(pMouseNode->getOutputSocket(2));


    gkKeyNode* pKeyNode= static_cast<gkKeyNode*>(pTree-
>createNode(NT_KEY));
    pKeyNode->getInputSocket(0)->setValue(true);
    pKeyNode->setKey(KC_AKEY);

    gkLogicNode* pMotionNode = pTree->createNode(NT_MOTION);

    pMotionNode->getInputSocket(0)->link(pKeyNode->getOutputSocket(1));
    pMotionNode->getInputSocket(1)->link(pMouseNode-
>getOutputSocket(1));
    pMotionNode->getInputSocket(2)->link(pMouseNode-
>getOutputSocket(2));


    pTree->solveOrder();

    pCamera->attachLogic(pTree);
}

I found some problems with the OIS library inside OgreKit. This library is 
not using DirectX for windows...

Some of the problems are:

1-) gkInternalWindowSystemPrivate::keyReleased function is never called...

2-) gkInternalWindowSystemPrivate::mousePressed is called sometimes (not 
always when you press a mouse button...)

I have tried compiling OIS 1.2.0 from 
http://sourceforge.net/projects/wgois/files/Source%20Release/1.2/ois_1.2.0.
zip/download

and everything work properly with that version.

It is a pity the OIS library inside GameKit (for windows) does not work 
correctly!!!

Note: I have tried also compiling with the "win32native" version and the 
bad behavior persist...

Any help?

What steps will reproduce the problem?
1. load this blend http://tecan.ath.cx/monkit2.blend
2. because its one mesh you only see one texture.
3.

Blender supports compressed .blend files, they are .blend files zipped.

They can be simply unzipped using any .zip decompressor, such as zlib.

As Blender 2.50 compresses by default, add support for this.

I will like to use boost header files inside OgreKit. Basically I will like 
to use boost-threads and some other boost header files...

you have to edit stdint in zziplib like this otherwise it gets build errors
with redefinitions.

typedef unsigned _zzip___int64 uint64_t; 
//typedef _zzip___int64 int64_t;

also for sound support use cAudio 2 its really good.

when i compile TEST_ECHO_BLEND_READER 0 defined it loads all the blends you
supplied nicely.

but TEST_ECHO_BLEND_READER 1 I gdb'd the segfault with it enabled

dna not matching...
File contains 1 scene(s)

also i had to change
BlendBlock * curveblockptr = blend_block_from_blendpointer(bf,
(uint32_t)ptr); to uint64_t to make it compile on 64bit

Ogre 1.7 has screen space ambient occlusion (SSOA) example. It would be good 
to create a similar example in GameKit.

Also, might be good looking into this one (see attached)

It will be nice to define gkLogicTree::createNode as a template method.
This will avoid to update the big switch (in the cpp) every time we create 
a new node.

This is my proposal. Change gkLogicTree::createNode in the header file for 
the following code (and remove cpp implementation):

    template<class T>
    T* createNode()
    {
        T* pNode = new T(this, m_uniqueHandle);

        GK_ASSERT(pNode);

        if(m_object) pNode->attachObject(m_object);

        m_nodes.push_back(pNode);

        m_uniqueHandle ++;

        return pNode;
    }

gkMouseNode is missing output socket for mouse pressed buttons:

For example for left (mouse) button this could be the code:

In the constructor add the following line:
ADD_OSOCK(mSockets[8],  this, gkLogicSocket::ST_BOOL); //Left button pressed

In gkMouseNode::evaluate add the following:
mSockets[8].setValue(dev.isButtonDown(gkMouseDevice::BUTTON_LEFT));

It would be nice to extract from gkScene the limits for all the static 
objects.

The interface could be something like this:

  const Ogre::AxisAlignedBox& gkScene::GetLimits() const;

This will allow me implementation of a depth map to be used in pathfinder 
algorithm (A*)

New classes: OgreBlend and BulletBlendReaderNew are not using core classes.
Why?

In fact core directory is depreciated in CMakeList.txt

For now please use Blender 2.49b and press L key, make local all.

either using Irrlicht OpenGL ES port, or Oolong Engine 
http://oolongengine.googlecode.com

Blender Game Engine supports Bullet soft body, and all data is available in 
the .blend file. Extract it and use it!

There is not support to register a gkLogicNode in order to get notifications 
for collisions...

Currently, GameKit supports Irrlicht and oolong Engine for graphics.

Now Ogre 1.7 goes MIT license, we can do an integration. Some 
projects/propotypes might work 
better with Irrlicht, others with Ogre.

gamekit-read-only/gamekit/BulletBlendReaderNew.cpp:23:37: error:
LinearMath/btserializer.h: No such file or directory

Make a correct relative path:
#include "../LinearMath/btserializer.h"

Or fix this with cmake include directories.

in main.cpp the user can set(m_prefs.winsize) but it is always ignored due
gkBlendFile::_parse function overwrites it from blend file...

See in gkBlendFile::_parse:

            gkUserDefs &defs = gkEngine::getSingleton().getUserDefs();
            defs.winsize.x = (gkScalar)sc->r.xplay;
            defs.winsize.y = (gkScalar)sc->r.yplay;
            defs.fullscreen = sc->r.fullscreen != 0;

reading larger .blend files is low. This is mainly due to excessive memory 
re-allocations, and linear 
searches. 

Re-write some of this, so the library is useable on iPhone, and for larger 
.blend files.

What steps will reproduce the problem?
1. get latest trunk
2. cmake . -G Xcode

I think that problem lies in $(ARCHS_STANDARD_32_64_BIT)  setting in 
Architectures of project. 
It builds without errors in 32 bit Universal setting, but there are still 272

Hope it helps.

Looks like the path generated by gkPath::directory is not recognized as a 
valid directory by gkPath::isDir function because the last separator added 
at the end of the path.


See example in OgreKit/Tests/ImplTest/Main.cpp

        gkPath p(argv[0]);
        if (p.isFile())
        {
            p = p.directory();
            if (p.isDir())

// *** WILL NEVER ENTER HERE ***

Please provide any additional information below.
Patch attached to fix this error.

Right now it is not easy to develop basic prototypes for PC, Mac and iPhone.

Create some simple framework that makes it easier.

Since "gkNodeTypes" is not needed anymore to create new nodes and the user 
can use typeid operator to extract "type_info" I suggest to remove this enum 
and all the references (constructors, member,...)

This also allows creation of new nodes without having to maintain this enum 
(at least for consistency with the old nodes....)

This little patch will make GameKit compile under Linux, thanks Olm-Z for
the X11_VIDMODE tip.

Plus, added a fix for compiling libpng under 64 bits (the MMX support fails
at linking time)

I tested under Fedora 9 64 bits and it compiled and the clubsilo demo runs
wonderfully :D.

64bit or big-endian .blend files are not supported indeed.

Those .blend files have to be load and saved by a 32bit little-endian Blender 
version for now.

This functionality is needed in order to have issue 32 implemented.

simplestate.blend and luahelloworld.blend load fine

any of the blend 32 bit blends with logic segfault,resaving them as 64 bit
blend files load fine on 64 bit arch though.

great work! you guys have been working hard it shows!

sorry for posting so many bugs but it wont let me comment on previous issues

It would be nice to have at core level some support to visualize physic 
shapes...

It will be nice to have non-exclusive input for the mouse & keyboard. (This 
will allow us interact with other windows while running GameKit app. Also 
will allow us to put breakpoints (debugging...).

This is the code to add in gkWindowSystem::createMainWindow :

        #if OGRE_PLATFORM == OGRE_PLATFORM_WIN32

        //////////////////////
        // Non-exclusive input
        params.insert(std::make_pair(std::string("w32_mouse"), 
std::string("DISCL_FOREGROUND" )));
        params.insert(std::make_pair(std::string("w32_mouse"), 
std::string("DISCL_NONEXCLUSIVE")));
        params.insert(std::make_pair(std::string("w32_keyboard"), 
std::string("DISCL_FOREGROUND")));
        params.insert(std::make_pair(std::string("w32_keyboard"), 
std::string("DISCL_NONEXCLUSIVE")));

        #else

        params.insert(std::make_pair(std::string("x11_mouse_grab"), 
std::string("false")));
        params.insert(std::make_pair(std::string("x11_mouse_hide"), 
std::string("false")));

params.insert(std::make_pair(std::string("x11_keyboard_grab"), 
std::string("false")));
        params.insert(std::make_pair(std::string("XAutoRepeatOn"),

Please provide any additional information below.

It does not make sense to block an OR-IF node if one of the input socket is 
blocked. I would like to have it blocked if both inputs are blocked...

To solve it, we can make the gkLogicNode::block method as virtual and 
redefine  the blocking logic in gkIfNode::block. Something like this could 
solve the problem:

void gkIfNode::block(bool truth)
{
    if(mStatement == CMP_OR && truth)
    {
        truth = mSockets[0].isBlocked() && mSockets[1].isBlocked();
    }

    gkLogicNode::block(truth);
}

Add an example of creating a Bullet ragdoll from a Ogre animation.

See also discussion here:
http://www.ogre3d.org/forums/viewtopic.php?f=1&t=54587#p371085

This functionality is needed if we want to use wheelDelta as an input socket.

Look into open source (MIT/BSD/Zlib licensed) networking libraries and add 
support for this.

I have attached a little fix

LUA is one of the popular scripting languages used in games, so experiment 
with an example.

http://www.lua.org/

Ok, so it's not exactly an issue (I don't know where suggestions go for
this project), but I thought it would be a nice option to have.

I already hacked it together on my own (diff attached), but it's probably
butchering things (because C++ is not exactly in my comfort zone).

Anyway, I like the whole idea behind the project. Keep up the good work.
