- the gp_GamePythonPath relative path variable wasnt updated when loading new files.
- missing NULL check for scene crashed blender when it failed to load a file.
Both problems dont affect blenderplayer

Fixed two bugs from original patch:
- deleting a text will clear the warp field from Game framing settings
- removed spurious black dots along the edge of the cube map in the gameplayer
Known limitation:
- resizing of the screen doesn't work in the gameplayer
Known bugs:
- Texture with reflexion are not rendered correctly
- Spurious problems with light
Previously this only worked with the Blender API.
- bpy_internal_import small C file that Blender scripting and the game engine use.
- Tested with blender, blenderplayer, loading files
- Needed to use a hack to override the Main struct since the game engine doesn't set G.main
- when the sandbox is set, only internal scripts can be imported.
- variables that shadow vers declared earlier
- Py_Fatal print an error to the stderr
- gcc was complaining about the order of initialized vars (for classes)
- const return values for ints and bools didnt do anything.
- braces for ambiguous if statements
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.
The only compilation system that works for sure is the MSVC project files. I've tried my best to
update the other compilation system but I count on the community to check and fix them.
This is Zdeno Miklas video texture plugin ported to trunk.
The original plugin API is maintained (can be found here http://home.scarlet.be/~tsi46445/blender/blendVideoTex.html)
EXCEPT for the following:
The module name is changed to VideoTexture (instead of blendVideoTex).
A new (and only) video source is now available: VideoFFmpeg()
You must pass 1 to 4 arguments when you create it (you can use named arguments):
VideoFFmpeg(file) : play a video file
VideoFFmpeg(file, capture, rate, width, height) : start a live video capture
file:
In the first form, file is a video file name, relative to startup directory.
It can also be a URL, FFmpeg will happily stream a video from a network source.
In the second form, file is empty or is a hint for the format of the video capture.
In Windows, file is ignored and should be empty or not specified.
In Linux, ffmpeg supports two types of device: VideoForLinux and DV1394.
The user specifies the type of device with the file parameter:
[<device_type>][:<standard>]
<device_type> : 'v4l' for VideoForLinux, 'dv1394' for DV1394; default to 'v4l'
<standard> : 'pal', 'secam' or 'ntsc', default to 'ntsc'
The driver name is constructed automatically from the device types:
v4l : /dev/video<capture>
dv1394: /dev/dv1394/<capture>
If you have different driver name, you can specify the driver name explicitely
instead of device type. Examples of valid file parameter:
/dev/v4l/video0:pal
/dev/ieee1394/1:ntsc
dv1394:ntsc
v4l:pal
:secam
capture:
Defines the index number of the capture source, starting from 0. The first capture device is always 0.
The VideoTexutre modules knows that you want to start a live video capture when you set this parameter to a number >= 0. Setting this parameter < 0 indicates a video file playback. Default value is -1.
rate:
the capture frame rate, by default 25 frames/sec
width:
height:
Width and height of the video capture in pixel, default value 0.
In Windows you must specify these values and they must fit with the capture device capability.
For example, if you have a webcam that can capture at 160x120, 320x240 or 640x480,
you must specify one of these couple of values or the opening of the video source will fail.
In Linux, default values are provided by the VideoForLinux driver if you don't specify width and height.
Simple example
**************
1. Texture definition script:
import VideoTexture
contr = GameLogic.getCurrentController()
obj = contr.getOwner()
if not hasattr(GameLogic, 'video'):
matID = VideoTexture.materialID(obj, 'MAVideoMat')
GameLogic.video = VideoTexture.Texture(obj, matID)
GameLogic.vidSrc = VideoTexture.VideoFFmpeg('trailer_400p.ogg')
# Streaming is also possible:
#GameLogic.vidSrc = VideoTexture.VideoFFmpeg('http://10.32.1.10/trailer_400p.ogg')
GameLogic.vidSrc.repeat = -1
# If the video dimensions are not a power of 2, scaling must be done before
# sending the texture to the GPU. This is done by default with gluScaleImage()
# but you can also use a faster, but less precise, scaling by setting scale
# to True. Best approach is to convert the video offline and set the dimensions right.
GameLogic.vidSrc.scale = True
# FFmpeg always delivers the video image upside down, so flipping is enabled automatically
#GameLogic.vidSrc.flip = True
if contr.getSensors()[0].isPositive():
GameLogic.video.source = GameLogic.vidSrc
GameLogic.vidSrc.play()
2. Texture refresh script:
obj = GameLogic.getCurrentController().getOwner()
if hasattr(GameLogic, 'video') != 0:
GameLogic.video.refresh(True)

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
Enable video support in ffmpeg for Linux.
* Debug text drawing didn't disable textures correct leaving
texture state invalid, quite old issue.
* Multitexture materials didn't get enabled correct, recent bug.
Both pointed out by José Ignacio Romero, thanks!
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.
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!
Improved Bullet soft body advanced options, still work-in-progress. Make sure to create game Bullet soft bodies from scratch, it is not compatible with last weeks builds.

would useually not encourage prints in these cases, except its often useful to know if an error happened since you last pressed Pkey and without this you end up needing to manually clear the terminal.
when pressing P without a camera active, now it should match
the view exactly.
Fix an issue when setting a camera with an actuator and being
in orthographic mode in the viewport without an active camera,
it used a strange mix of the set camera and the viewport then.
the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.
This is odd because BLO_read_from_file was commented out with """//this doesn't work anymore for relative paths, so use BLO_read_from_memory instead"""
Undoing Erwins changes from r7497, just use normal file loading. From the commit log its not clear if he means relative filenames or relative linked libs but from testing both work now.
nurbs/curves/text dissappears.
This also removes the "vertex arrays" option and enables it always
for OpenGL version >= 1.1 - there's no need to have an option to
make things render faster disabled by default, also it should work
stable now.
GLEW
====
Added the GLEW opengl extension library into extern/, always compiled
into Blender now. This is much nicer than doing this kind of extension
management manually, and will be used in the game engine, for GLSL, and
other opengl extensions.
* According to the GLEW website it works on Windows, Linux, Mac OS X,
FreeBSD, Irix, and Solaris. There might still be platform specific
issues due to this commit, so let me know and I'll look into it.
* This means also that all extensions will now always be compiled in,
regardless of the glext.h on the platform where compilation happens.
Game Engine
===========
Refactoring of the use of opengl extensions and other drawing code
in the game engine, and cleaning up some hacks related to GLSL
integration. These changes will be merged into trunk too after this.
The game engine graphics demos & apricot level survived my tests,
but this could use some good testing of course.
For users: please test with the options "Generate Display Lists" and
"Vertex Arrays" enabled, these should be the fastest and are supposed
to be "unreliable", but if that's the case that's probably due to bugs
that can be fixed.
* The game engine now also uses GLEW for extensions, replacing the
custom opengl extensions code that was there. Removes a lot of
#ifdef's, but the runtime checks stay of course.
* Removed the WITHOUT_GLEXT environment variable. This was added to
work around a specific bug and only disabled multitexturing anyway.
It might also have caused a slowdown since it was retrieving the
environment variable for every vertex in immediate mode (bug #13680).
* Refactored the code to allow drawing skinned meshes with vertex
arrays too, removing some specific immediate mode drawing functions
for this that only did extra normal calculation. Now it always splits
vertices of flat faces instead.
* Refactored normal recalculation with some minor optimizations,
required for the above change.
* Removed some outdated code behind the __NLA_OLDDEFORM #ifdef.
* Fixed various bugs in setting of multitexture coordinates and vertex
attributes for vertex arrays. These were not being enabled/disabled
correct according to the opengl spec, leading to crashes. Also tangent
attributes used an immediate mode call for vertex arrays, which can't
work.
* Fixed use of uninitialized variable in RAS_TexVert.
* Exporting skinned meshes was doing O(n^2) lookups for vertices and
deform weights, now uses same trick as regular meshes.
[#7113] GE crash pressing as soon as P on 64 bit
Note: glext.h has been removed from the source
If you get errors compiling with it you have 2 options
download/install glext.h (preferred method)
or set WITH_BF_GLEXT=false
If your a user and having problems with game engine try
setting the env var: WITHOUT_GLEXT 1
Kent
fix for [#6950] Blender crashes when .blog file top line is 160 characters or more
- made sure BLI_convertstringcode doesn't return more than 240 chars
- went through all callers and fixed places where string passed to BLI_convertstringcode was too short
- TODO: look into increasing sample->name and sound->name too, I prevented crashes, but filename might get shortened.
* Make PyNodes work with threaded renderer. This patch is by Willian. He has worked hard on getting this sorted out - now you should be able to render with PyNodes AND multiple threads.
This adds fractional FPS support to blender and should finally
make NTSC work correctly.
NTSC has an FPS of 30.0/1.001 which is approximately 29.97 FPS.
Therefore, it is not enough to simply make frs_sec a float, since
you can't represent this accurately enough.
I added a seperate variable frs_sec_base and FPS is now
frs_sec / frs_sec_base.
I changed all the places, where frs_sec was used to my best knowledge.
For convenience sake, I added several macros, that should make life
easier in the future:
FRA2TIME(a) : convert frame number to a double precision time in seconds
TIME2FRA(a) : the same in the opposite direction
FPS : return current FPS as a double precision number
(last resort)
This closes bug #6715
Standard framerates not supported / breaks sync -- 23.967 29.967 etc.
https://projects.blender.org/tracker/?func=detail&aid=6715&group_id=9&atid=125
Please give this heavy testing with NTSC files, quicktime in/export
and the python interface.
Errors are most probably only spotted on longer timelines, so that is
also important.
The patch was tested by Troy Sobotka and me, so it most probably should
work out of the box, but wider testing is important, since errors are
very subtle.
Enjoy!
copy system with rigidbody constraint will link new constraints to new objects (instead of old)
fps from blender will be used when baking (left shift/ctrl/alt + P)
- GEdon't crash when attempting to add constraint on game objects without physics controller
- GEimproved some physics -> graphics synchronization issues
- small experiment with game engine timing to smooth framerate/reduce tearing
Although we will delay the main Rigid Body user interface after 2.43 release early 2007, I need some constraint data/UI to make progress with COLLADA Physics.
Added RigidBody constraint UI
LR_ALTKEY+LR_CTRLKEY+LR_SHIFTKEY+ P will bake rigidbody
Contribution by RCRuiz, Ramon Carlos.
Cleared the python dictionary at the end of the game engine, should fix some issues,
also reverted the python controller changes, related to this
This should fix the following bugs:
[ #3789 ]
[ #3815 ]
possiblyy fixes:
[ #3834 ]
(with make, need to confirm with scons)
after cleaning the changes are in fact minimal, but the situation
is still quite a bit hackish.
Game engine coders, there is also quite a number of warnings that
need to be fixed.
current situation is that everything seems to work, but GLSL shaders
spew a lot of errors on console and blender may crash on exit when
a GLSL shader was used. ARB stuff works fine.
Armatures are back
Split screen
Double sided lightning
Ambient lighting
Alpha test
Material IPO support (one per object atm)
Blender materials
GLSL shaders - Python access
Up to three texture samplers from the material panel ( 2D & Cube map )
Python access to a second set of uv coordinates
See http://www.elysiun.com/forum/viewtopic.php?t=58057
including implementation. hope it works, and doesn't break to much.
it bakes physics objects transform into ipo, every frame of the running gameengine.
When you disable and run the game again, it clears the ipo's again. just for physics objects at the moment.
(perhaps some better UI in the future?)
