adaa4b0fd0 Making KX_GameObject names read only.
This was committed in revision 2832 but never accounted for existing object name hashes which existed since revision 2.

Its possible to update the names elsewhere but unlikely anyone ever used this successfully so removing.

* fixed segfaults in CListValue.index(val) and CListValue.count(val) when the pyTypes could not be converted into a CValue.
* added scene.objects to replace scene.getObjectList()
* added function names to PyArg_ParseTuple() so errors will include the function names 
* removed cases of PyArg_ParseTuple(args,"O",&pyobj) where METH_O ensures a single argument.
* Made PyObjectFrom use ugly python api rather then Py_BuildValue(), approx %40 speedup for functions that return Python vector and matrix types like ob.orientation.

cdec2b3d15 BGE Python API
Use 'const char *' rather then the C++ 'STR_String' type for the attribute identifier of python attributes.

Each attribute and method access from python was allocating and freeing the string.
A simple test with getting an attribute a loop shows this speeds up attribute lookups a bit over 2x.

c3d74547be SCons:
* giving compileflags, cc_compileflags and cxx_compileflags to BlenderLib() now actually overrides any other setting (so there's no unclarity when ie. conflicting options are being specified in REL_CFLAGS et al). These are set after either release or debug flags, but before any *_WARN flags (so those stay maintained).
* add cxx_compileflags for GE parts on win32-vc to have better performance.
* NOTE: if platform maintainers (OSX and Linux) could check and do the same for their systems. Not vital, but probably very, very much welcomed by GE users.

509ca83ef1 BGE patch 18065: gameobj mass writeable + setmass actuator. This patch allows to change the mass of a dynamic or rigid body object during the game. Two methods are available: in a Python script by setting the mass attribute of the game object; by logic brick with the Edit Object->Dynamics->Set Mass actuator. The mass can only be set on dynamic objects and must be a positive floating point value. 2009-01-14 22:33:39 +00:00

00c12e0906 BGE patch: dynamically update the coumpound parent shape when parenting to a compound object.
This patch modifies the way the setParent actuator and KX_GameObject::setParent() function
works when parenting to a compound object: the collision shape of the object being parented
is dynamically added to the coumpound shape. 
Similarly, unparenting an object from a compound object will cause the child collision shape
to be dynamically removed from the parent shape provided that is was previously added with 
setParent.

Note: * This also works if the object is parented to a child of a compound object: the
        collision shape is added to the compound shape of the top parent.
      * The collision shape is added with the transformation (position, scale and orientation)
        it had at the time of the parenting.
      * The child shape is rigidly attached to the compound shape, the transformation is not
        affected by any further change in position/scale/orientation of the child object.
      * While the child shape is added to the compound shape, the child object is removed from
        the dynamic world to avoid superposition of shapes (one for the object itself and
        one for the compound child shape). This means that collision sensors on the child
        object are disabled while the child object is parent to a compound object.
      * There is no difference when setParent is used on a non-compound object: the child
        object is automatically changed to a static ghost object to avoid bad interaction
        with the parent shape; collision sensors on the child object continue to be active
        while the object is parented.
      * The child shape dynamically added to a compound shape modifies the inertia of the
        compound object but not the mass. It participates to collision detection as any other
        "static" child shape.

1c663bbc7e First batch of GE API cleanup.
The principle is to replace most get/set methods of logic bricks by direct property access. 
To make porting of game code easier, the properties have usually the same type and use than
the return values/parameters of the get/set methods. 
More details on http://wiki.blender.org/index.php/GameEngineDev/Python_API_Clean_Up

Old methods are still available but will produce deprecation warnings on the console: 

"<method> is deprecated, use the <property> property instead"

You can avoid these messages by turning on the "Ignore deprecation warnings" option in Game menu.

PyDoc is updated to include the new properties and display a deprecation warning
for the get/set methods that are being deprecated.

149d231d69 VideoTexture: new ImageMirror class for easy mirror (and portal) creation
The new class VideoTexture.ImageMirror() is available to perform
automatic mirror rendering.

Constructor:

  VideoTexture.ImageMirror(scene,observer,mirror,material)
    scene:    reference to the scene that will be rendered.
              Both observer and mirror must be part of that scene.
    observer: reference to a game object used as view point for
              mirror rendering: the scene will be rendered through
              the mirror as if the active camera was at the observer 
              location. Usually the observer is the active camera
              but you can use any game obejct.
    mirror:   reference to the mesh object holding the mirror.
    material: material ID of the mirror texture as returned by 
              VideoTexture.materialID(). The mirror is formed by 
              the polygons mapped to that material.

There are no specific methods or attributes. ImageMirror inherits 
all methods and attributes from ImageRender. You must refresh the
parent VideoTexture.Texture object regularly to update the mirror 
rendering.

Guidelines on how to create a working mirror:
- Use a texture that is specific to the mirror so that the mirror 
  rendering only appears on the mirror.
- The mirror must be planar; the algorithm works well only for planar
  or quasi planar mirror. For spherical mirror, you will get better
  results with ImageRender and a camera at the center of the mirror. 
  ImageMirror automatically computes the mirror orientation and 
  position. The mirror doesn't need to be rectangular, it can be 
  circular or take any form provided it is planar.
- The mirror up direction must be along the Z axis in local mesh
  coordinates. If the mirror is not vertical, ImageMirror will 
  compute the up direction as being the projection of the Z axis
  on the mirror plane.
- UV mapping must be set right to get correct mirror rendering:
  - make a planar projection of the mirror polygons (Unwrap or projection from view)
  - eventually rotate the projection so that UV up direction corresponds to the mesh Z axis
  - scale the projection so that the extreme points touch the border of the texture
  - flip the UV projection horizontally (scale -1 on X axis). This is needed
    because the mirror texture is rendered from the back of the mirror and
    thus is reversed from the view point of the observer. Horizontal flip 
    in the UV map restores the correct orientation.

Besides these simple rules, the mirror rendering is completely automatic. 
In particular, you don't need to allocate a camera for the rendering, 
ImageMirror creates dynamically a camera for that. The reflection is correct
even on large angles. The mirror can be a dynamic and moving object, the 
algorithm always computes the correct camera position based on observer 
relative position. You don't have to worry about mirror position in the scene: 
the algorithm automatically computes the camera frustum so that any object 
behind the mirror is not rendered.

Warnings:
- observer and mirror are references to game objects. ImageMirror keeps
  a pointer to them but does not increment the reference count. You must ensure 
  that these game objects are not deleted as long as you refresh() the ImageMirror
  object. You must release the ImageMirror object before you delete the game
  objects. To release the ImageMirror object (normally stored in GameLogic),
  just assign it to None.
- Mirror rendering is automatically skipped when the observer is behind the mirror
  but it is not disabled when the mirror is out of sight of the observer.
  You should only refresh the mirror when you know that the observer is likely to see it.
  For example, no need to refresh a car inner mirror when the player is not in the car.

Example:

  contr = GameLogic.getCurrentController()
  # object holding the mirror
  mirror = contr.getOwner()
  scene = GameLogic.getCurrentScene()
  # observer will be the active camere
  camera = scene.getObjectList()['OBCamera']
  matID = VideoTexture.materialID(mirror, 'IMmirror.png')
  GameLogic.mirror = VideoTexture.Texture(mirror, matID)
  GameLogic.mirror.source = VideoTexture.ImageMirror(scene,camera,mirror,matID)
  # to render the mirror, just call GameLogic.mirror.refresh(True) on each frame.

For those who have already downloaded the demo, you can just update the blend file:

77b4c66cc3 Preparation to VideoTexture: everything but the VideoTexture module itself.
Rename PHY_GetActiveScene() to KX_GetActiveScene(): more logical name
Add KX_GetActiveEngine()

new KX_KetsjiEngine::GetClockTime(void) to return current 
render frame time: if the CPU does not keep up with the 
frame rate, up to 5 consecutive logic frames are processed 
between each render frame, so that the logic system stays 
accurate even if the graphic system is slow. For the video 
texture module, it is important to stay in sync with the
render frame: no need to update the texture for logic frame.

BL_Texture::swapTexture(): texture id manipulation
BL_Texture::getTex() : return material texture

bf0440add8 BGE bug fix (continuation of previous bug fix):
- Forgot to make SCA_ISensor::UnregisterToManager() virtual to intercept active-inactive transition on collision sensor to clear colliders reference.
- Don't record collision on inactive sensor. 
  This situation occurs when an object with an inactive collision sensor collides with an object with an active collision sensor: the collision handler triggers both sensors.
  The result of this bug was pending references that eventually cause temporary memory leak (until the sensor is reactivated).

- Clear all references in KX_TouchSensor::m_colliders when the sensor is disabled to avoid loose references. 
- Test GetSGNode() systematically for all KX_GameObject functions that can be called from python in case a python controller keeps a reference in GameLogic (bad practice anyway).

9b948cad08 Fix for a relative paths issue in the game engine. G.sce was being
kept as the original file, but that can't work correct for solving
relative paths once a .blend in another directory is loaded. The
reason it went OK with the apricot tech demo is that the images there
were lib linked into the level file, which still worked.

Now it sets G.sce to the current loaded .blend file. Note that the
python config file path still uses the first loaded .blend file so it
looks in the same location each time.

Also added some NULL pointer checks in the joystick code because it
was crashing there on Mac, there's similar checks in related functions
so I'm assuming this was just a missed case.

8550c2b594 BGE patch: new force field constraint actuator
A new type of constraint actuator is available: Force field.
It provides a very similar service to the Fh material feature
but with some specificities:
- It is defined at the object level: each object can have 
  different settings and you don't need to use material.
- It can be applied in all 6 directions and not just -Z.
- It can be enabled/disabled easily (it's an actuator).
- You can have multiple force fields active at the same time
  on the same object in different direction (think of a 
  space ship in a tunnel with a repulsive force field
  on each wall).
- You can have a different damping for the rotation.

Besides that it provides the same dynamic behavior and the 
parameters are self explanatory.
It works by adapting the linear and angular velocity: the
dynamic is independent of the mass. It is compatible with
all other motion actuators.

Note: linear and anysotropic friction is not yet implemented,
the only friction will come from the object damping parameters. 
Support for friction will be added in a future revision.

add -nojoystick commandline option: it takes 5 seconds everytime to start the game engine, while there IS no joystick.

In other words: blender -noaudio -nojoystick improves workflow turnaround times for P - ESC from 7 seconds to 1 second!

8e1cf42dbd BGE patch: local/global flag to distance contraint actuator.
Previously the distance constraint actuator was always working
in local axis. The local flag allows to cast the ray along a
world axis (when the flag is not selected). 
The N flag works differently in this case: only the object 
orientation is changed to be parallel to the normal at the hit
point. 

The linear velocity is now changed so that the speed along the 
ray axis is null. This eliminates the need to compensate the 
gravity when casting along the Z axis.
