14d33b3c1f BGE guardedalloc, Uses WITH_CXX_GUARDEDALLOC but gives a string to MEM_mallocN for better tracking memory usage.
* off by default.
* new/delete are at the bottom of each class
* python BGE objects have the new/delete in the Py_Header macro.

dd918da8de ReplaceMesh Actuator option to replace the physics mesh and display mesh + python api options.
When the mesh field is left blank and Physics option is enabled, it reinstances the physics mesh from the existing mesh.
like calling gameOb.reinstancePhysicsMesh() from python.

386122ada6 BGE performance, 4th round: logic
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

5d0a207ecb Patch from GSR that a) fixes a whole bunch of GPL/BL license
blocks that were previously missed; and b) greatly increase my
ohloh stats!

51ea7645e2 Fix BGE bug: BGE will crash if objects with display debug property is deleted (bad practice anyway). The actual deletion is now postponed until end of scene 2008-04-01 20:46:20 +00:00

ab71e2a9b5 -added basic support for GameActuator 'load game', relative paths were broken, just load file into memory and load blend from memory.
-near sensor support
- python binding for PhysicsConstraints.setNumTimeSubSteps (dividing the physics timestep to tradeoff quality for performance)

f1c4f705a1 Removed the config.h thing from the .h's in the source dir.
So we should be all set now :)

b9a19f1ea7 Did all of the .h's in source
(adding)
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif

also the Makefile.in's were from previous patch adding
the system depend stuff to configure.ac

01bff70383 fixed spacing in the headers to get rid of some warnings and some other
little minor spacing issues.
