Implementation of the PHY_IPhysicsController::SetMargin(),
GetMargin(), SetRadius() and GetRadius() for Bullet and Sumo
to allow resetting the Near sensor radius. For bullet use
the new setUnscaledRadius() function to change sphere radius.
In pPreparation of a Fh constraint actuator:
- Add KX_IPhysicsController::GetRadius()
- Fix implementation of KX_BulletPhysicsController::GetVelocity()
(velocity at a point in geometric coordinate)
- Don't try to set velocity on static object (Bullet will assert)
- Add KX_GameObject::GetVelocity() for C access to local velocity
rayCast(to,from,dist,prop,face,xray,poly):
The face paremeter determines the orientation of the normal:
0 or omitted => hit normal is always oriented towards the ray origin (as if you casted the ray from outside)
1 => hit normal is the real face normal (only for mesh object, otherwise face has no effect)
The ray has X-Ray capability if xray parameter is 1, otherwise the first object hit (other than self object) stops the ray.
The prop and xray parameters interact as follow:
prop off, xray off: return closest hit or no hit if there is no object on the full extend of the ray.
prop off, xray on : idem.
prop on, xray off: return closest hit if it matches prop, no hit otherwise.
prop on, xray on : return closest hit matching prop or no hit if there is no object matching prop on the full extend of the ray.
if poly is 0 or omitted, returns a 3-tuple with object reference, hit point and hit normal or (None,None,None) if no hit.
if poly is 1, returns a 4-tuple with in addition a KX_PolyProxy as 4th element.
The KX_PolyProxy object holds information on the polygon hit by the ray: the index of the vertex forming the poylgon, material, etc.
Attributes (read-only):
matname: The name of polygon material, empty if no material.
material: The material of the polygon
texture: The texture name of the polygon.
matid: The material index of the polygon, use this to retrieve vertex proxy from mesh proxy
v1: vertex index of the first vertex of the polygon, use this to retrieve vertex proxy from mesh proxy
v2: vertex index of the second vertex of the polygon, use this to retrieve vertex proxy from mesh proxy
v3: vertex index of the third vertex of the polygon, use this to retrieve vertex proxy from mesh proxy
v4: vertex index of the fourth vertex of the polygon, 0 if polygon has only 3 vertex
use this to retrieve vertex proxy from mesh proxy
visible: visible state of the polygon: 1=visible, 0=invisible
collide: collide state of the polygon: 1=receives collision, 0=collision free.
Methods:
getMaterialName(): Returns the polygon material name with MA prefix
getMaterial(): Returns the polygon material
getTextureName(): Returns the polygon texture name
getMaterialIndex(): Returns the material bucket index of the polygon.
getNumVertex(): Returns the number of vertex of the polygon.
isVisible(): Returns whether the polygon is visible or not
isCollider(): Returns whether the polygon is receives collision or not
getVertexIndex(vertex): Returns the mesh vertex index of a polygon vertex
getMesh(): Returns a mesh proxy
New methods of KX_MeshProxy have been implemented to retrieve KX_PolyProxy objects:
getNumPolygons(): Returns the number of polygon in the mesh.
getPolygon(index): Gets the specified polygon from the mesh.

With this patch, only sensors that are connected to
active states are actually registered in the logic
manager. Inactive sensors won't take any CPU,
especially the Radar and Near sensors that use a
physical object for the detection: these objects
are removed from the physics engine.
To take advantage of this optimization patch, you
need to define very light idle state when the
objects are inactive: make them transparent, suspend
the physics, keep few sensors active (e,g a message
sensor to wake up), etc.
here is a quick summary...
Kent
intern/bsp/intern/BSP_CSGMesh_CFIterator.h
removed tri_index (unused variable)
intern/bsp/intern/CSG_BooleanOps.cpp
removed extra ;
intern/string/intern/STR_String.cpp
added <ctype.h>
source/blender/blenkernel/BKE_writeavi.h
moved things around so not doing forward declarations
source/blender/renderconverter/intern/convertBlenderScene.c
changed render.h to render_types.h
source/blender/src/blenderbuttons.c
source/blender/src/editgroup.c
source/blender/src/meshtools.c
added newline
source/gameengine/Ketsji/KX_KetsjiEngine.cpp
commented out include "PIL_time.h" code that requires it is commented out
reading blender/src/writeavicodec.c
(struct keyword to a couple of lines that needed it)
and added:
extern struct Render R;
blender/renderconverter/intern/convertBlenderScene.c
added extern Render R;
added #include "rendercore.h" to get rid of undeclared shade_material_loop
(Not sure if this is right but it fixes it.
Did not fix this problem, is it alright to just pass NULL here or should we chan
ge it to something else:
init_render_materials' : too few
gameengine/Physics/BlOde/OdePhysicsEnvironment.cpp
removed argument to dHashSpaceCreate
commented out dWorldQuickStep since it does not exist
Keyboard sensors can now hook escape key. Ctrl-Break can be used from within blender if you've forgotten an end game actuator.
Fixed a stupid bug preventing some actuators working (like TrackTo).
* Blender static now links. By default this option is disabled on all
platforms. Simply set the option in config.opts to 'true'.
* Added the following flags to config.opts:
- HOST_CC. This is the C compiler for the host platform. This value is the
same as TARGET_CC when not cross compiling.
- HOST_CXX. This is the C++ compiler for the host platform. This value is
the same as TARGET_CXX when not cross compiling.
- TARGET_CC. This is the C compiler for the target platform.
- TARGET_CXX. This is the C++ compiler for the target platform.
- TARGET_AR. This is the linker command for linking libraries.
- PATH This is the standard search path
All SConscript files have been updated to reflect these changes. Now it's
possible to change only the root SConstruct file, and all compiler specific
variables are passed automatically to all SConscript files. Of course, this
does not apply to makesdna because there the host and target platform is
different from all other libraries.
To pass a variable that applies to all platforms, all we now have to do is
set the correct value in library_env
Note: as usual, to get the latest options in the config.opts file, first
remove your version.
* Game engine can now be build on Linux. By default this feature is disabled.
The reason is that you need to have a precompiled version of the ode library
for your gcc version.
To enable ode support you need to do the following:
- compile ode.
- set BUILD_GAMEENGINE = 'true' in the config.opts file.
- set USE_PHYSICS='ode' in the config.opts file.
- set the ODE_INCLUDE and ODE_LIBPATH to valid locations.
* Linking order has changed for the game engine
There are cyclic dependencies between libraries. On linux we have to do some
duplicate linking. I looked at the order of linking in source/Makefile, and
did some clean up.
* libraries are now generated in [BUILD_DIR]/lib
* passed the user_options to all libraries now.
This means I could remove a couple of Export/Import lines.
* Changed the order in source/blender/src/SConscript and
source/gameengine/SConscript.
All libraries are now sorted alphabetically. This has no impact on the build
process.
* Windows .exe file now includes the blender icon.
* Builds with game engine on Windows only.
I tried building the game engine on Linux, but I get weird errors when
building with ode. There's a dirty #include path in
Physics/BlOde/OdePhysicsEnvironment.cpp (../ode/src/joint.h). gcc doesn't
like this somehow.
* Other platforms need to add a couple of flags to the SConstruct:
use_sumo, use_ode, solid_include and ode_include
(also adding a couple of include pathes)
changes in Ode*.cpp to get it compile with gcc 2.95.4
to make it compile with ./configure --with-gameengine
--enable-gameplayer

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