Particles using group-duplication, with Metaballs in group, enter eternal
loop in our code now. This is a non-supported case... metaball code doesn't
support recursions. Added a provision in code to catch this case, and print
an error in console to denote this.
scene.active_camera can now be set so you can more easily set the current camera from python scripts without using an actuator.
ConvertPythonToCamera utility function to get a camera from a python string or KX_Camera type.
fix/workaround - offset by a 500th of a pixel to avoid baking missing pixels that are between 2 faces, its still possible pixels could be between faces but much less likely then it is currently with pixel aligned UVs.
* FBX Bugfix, was exporting all animation curves as 'Constant' type (no docs for this so could only guess), Thanks to Sander Brandenburg for spotting this problem.
Also improved keyframe removal to work on animation curves an angle
Looked into ways around this but epydoc has no way to import a class without its module and the @include field is maked as 'TODO'.
Also removed the outdated 'WhatsNew' section and linked to the 2.49 release notes.
from Alberto Santos (dnakhain)
Changed "None" to "" for returning an unset vertex group.
"" is a valid name for a vertex group this is asking for trouble.
Its still not working right in perspective mode.
For bleed use a faster method then Barycentric weights function since the point is always on the edge.
last commit with memset in readfile.c missed one var.
fix this by freeing the lib-file-data after linking or appending, re-appending will be slower now
(as slow as appending for the first time).
Not strictly needed, set the memory for bhead's to zero in readfile.c since comparisons are done later on with this data making valgrind complain.
Added some missing headers too.
This made it not refresh the module when taking an external BGE Module and making it internal because the external pyc would never be freed so the internal text wouldn't get used until restarting blender.
--- Notes from Roelf, maybe some other BGE devs could help resolve these
Here is what I have so far. I've left "TODO's" were there needs to be some more comments.
The following things also need to be resolved:
-KX_VehicleWrapper.getWheelOrientationQuaternion looks like it should return a quaternion but if I look at the code it looks like it returns a rotation matrix.
-I still need to find out what exactly KX_VehicleWrapper.getWheelRotation is. I've got the return type but I would like to add some explanation for what it actualy means (and units if any).
-BL_Shader.setNumberOfPasses ignores the parameter but from the comment in the code it looks like the parameter that is being set (it is harcoded to be =1) in setNumberOfPasses is not used. So I'm not sure if this method should be documented at all.
This commit extends the technique of dynamic linked list to the logic
system to eliminate as much as possible temporaries, map lookup or
full scan. The logic engine is now free of memory allocation, which is
an important stability factor.
The overhead of the logic system is reduced by a factor between 3 and 6
depending on the logic setup. This is the speed-up you can expect on
a logic setup using simple bricks. Heavy bricks like python controllers
and ray sensors will still take about the same time to execute so the
speed up will be less important.
The core of the logic engine has been much reworked but the functionality
is still the same except for one thing: the priority system on the
execution of controllers. The exact same remark applies to actuators but
I'll explain for controllers only:
Previously, it was possible, with the "executePriority" attribute to set
a controller to run before any other controllers in the game. Other than
that, the sequential execution of controllers, as defined in Blender was
guaranteed by default.
With the new system, the sequential execution of controllers is still
guaranteed but only within the controllers of one object. the user can
no longer set a controller to run before any other controllers in the
game. The "executePriority" attribute controls the execution of controllers
within one object. The priority is a small number starting from 0 for the
first controller and incrementing for each controller.
If this missing feature is a must, a special method can be implemented
to set a controller to run before all other controllers.
Other improvements:
- Systematic use of reference in parameter passing to avoid unnecessary data copy
- Use pre increment in iterator instead of post increment to avoid temporary allocation
- Use const char* instead of STR_String whenever possible to avoid temporary allocation
- Fix reference counting bugs (memory leak)
- Fix a crash in certain cases of state switching and object deletion
- Minor speed up in property sensor
- Removal of objects during the game is a lot faster
controller.actuators[name] and controller.sensors[name]
Made a read-only sequence type for logic brick sensors and actuators which can access single items or be used like a list or dictionary.
We could use a python dictionary or CValueList but that would be slower to create.
So you can do...
for s in controller.sensors: print s
print controller.sensors["Sensor"]
print controller.sensors[0]
sensors = list(controller.sensors)
This sequence type keeps a reference to the proxy it came from and will raise an error on access if the proxy has been removed.
Commit 20099 started using a FBO way too big.
According to Paul Bourke this is how it's done in other Engines:
Projectors HD:
1920x1050 - buffersize = 1024; FBO size = 2048
1400x1050 - buffersize = 1024; FBO size = 2048
Projectors XGA:
1024x768 - buffersize = 512; FBO size = 1024
Now in Blender Game Engine we are using:
Projectors HD:
1920x1050 - buffersize = 1050; FBO size = 2048
1400x1050 - buffersize = 1050; FBO size = 2048
Projectors XGA:
1024x768 - buffersize = 768; FBO size = 1024
(I guess I should be committing code to the ge_dome branch instead of the trunk. I feel bad doing all those adjustments in a hurry to 2.49 final release in the trunk. That is ok, right?)
*) a small note:
In the end it turned out that we have upright and downright domes out there.
So I may rearrange the order of the gui later:
(1 = fisheye, 2 = truncated up, 3 = truncated down, 4 = envmap, 5 = spherical panoramic)
I don't plan to do a doVersion() for that, so if you are using it already keep in mind that the modes may change before 249 final release.
After last commit (20099) warping meshes got slower (more quality == less performance). Since we don't need an extra warping for truncated domes, It's better to handle them directly in openGL without the need of warping it.
I'll talk with some Dome owners to see if we need both Upright and Downright modes. I may remove one of them by 2.49 them.
*) also: a proper GLEW_EXT_framebuffer_object check before generating FBO (for warping meshes).
**) next in line (maybe after RC2): tilt option to tilt the camera up to 90º upward.
We are using an image twice as big to render the fisheye before warping.
It'll slow down warping meshes a little, but we get way more resolution.
Therefore I will bring Truncated Dome mode back in order to avoid using warping mesh for that.
not fixed but the problem is now less bad when projection painting, bilinear interpolation was rounding down.
- added gameOb.attrDict to get the internal gameObject dict.
- mesh.getVertex wasnt setting an exception.
