c73f82b6f0 Fix T37040: Removing vehicles in BGE causes a crash
The vehicle constraint is now properly removed if bge.constraints.removeConstraint()
is used or the object is deleted. This also fixes a memory leak with the
vehicle wrapper.

b90de0331d BGE: Cleaning up the BGE's physics code and removing KX_IPhysicsController and KX_BulletPhysicsController. Instead, we just use PHY_IPhysicsController, which removes a lot of duplicate code.
This is a squashed commit of the following:
    BGE Physics Cleanup: Fix crashes with LibLoading and replication. Also fixing some memory leaks.
    BGE Physics Cleanup: Removing KX_IPhysicsController and KX_BulletPhysicsController.
    BGE Physics Cleanup: Moving the replication code outside of KX_BlenderBulletController and switching KX_ConvertPhysicsObjects to create a CcdPhysicsController instead of a KX_BlenderBulletController.
    BGE Physics Cleanup: Getting rid of an unsued KX_BulletPhysicsController.h include in KX_Scene.cpp.
    BGE Physics Cleanup: Removing unused KX_IPhysicsController and KX_BulletPhysicsController includes.
    BGE Physics Cleanup: Removing m_pPhysicsController1 and GetPhysicsController1() from KX_GameObject.
    BGE Physics Cleanup: Remove SetRigidBody() from KX_IPhysicsController and remove GetName() from CcdPhysicsController.
    BGE Physics Cleanup: Moving Add/RemoveCompoundChild() from KX_IPhysicsController to PHY_IPhysicsController.
    BGE Physics Cleanup: Removing GetLocalInertia() from KX_IPhysicsController.
    BGE Physics Cleanup: Making BlenderBulletCharacterController derive from PHY_ICharacter and removing CharacterWrapper from CcdPhysicsEnvironment.cpp. Also removing the character functions from KX_IPhysicsController.
    BGE Physics Cleanup: Removing GetOrientation(), SetOrientation(), SetPosition(), SetScaling(), and GetRadius() from KX_IPhysicsController.
    BGE Physics Cleanup: Removing GetReactionForce() since all implementations returned (0, 0, 0). The Python interface for KX_GameObject still has reaction force code, but it still also returns (0, 0, 0). This can probably be removed as well, but removing it can break scripts, so I'll leave it for now.
    BGE Physics Cleanup: Removing Get/SetLinVelocityMin() and Get/SetLinVelocityMax() from KX_IPhysicsController.
    BGE Physics Cleanup: Removing SetMargin(), RelativeTranslate(), and RelativeRotate() from KX_IPhysicsController.
    BGE Physics Cleanup: Using constant references for function arguments in PHY_IPhysicsController where appropriate.
    BGE Physics Cleanup: Removing ApplyImpulse() from KX_IPhysicsController.
    BGE Physics Cleanup: Removing ResolveCombinedVelocities() from KX_IPhysicsController.
    BGE Physics Cleanup: Accidently removed a return when cleaning up KX_GameObject::PyGetVelocity().
    BGE Physics Cleanup: Remove GetLinearVelocity(), GetAngularVelocity() and GetVelocity() from KX_IPhysicsController. The corresponding PHY_IPhysicsController functions now also take Moto types instead of scalars to match the KX_IPhysicsController interface.
    BGE Physics Cleanup: Moving SuspendDynamics, RestoreDynamics, SetMass, GetMass, and SetTransform from KX_IPhysicsController to PHY_IPhysicsController.
    BGE Physics Cleanup: PHY_IPhysicsEnvironment and derived classes now use the same naming scheme as PHY_IController.
    BGE Physics Cleanup: PHY_IMotionState and derived classes now use the same naming convention as PHY_IController.
    BGE Phsyics Cleanup: Making PHY_IController and its derived classes follow a consistent naming scheme for member functions. They now all start with capital letters (e.g., setWorldOrientation becomes SetWorldOrientation).
    BGE Physics Cleanup: Getting rid of KX_GameObject::SuspendDynamics() and KX_GameObject::RestoreDynamics(). Instead, use the functions from the physics controller.
    BGE: Some first steps in trying to cleanup the KX_IPhysicsController mess. KX_GameObject now has a GetPhysicsController() and a GetPhysicsController1(). The former returns a PHY_IPhysicsController* while the latter returns a KX_IPhysicsController. The goal is to get everything using GetPhysicsController() instead of GetPhysicsController1().

815e00917d BGE cleanup: Removing the PHY__Vector classes and replacing them with MT_Vectors. The PHY__Vectors didn't offer anything (not even any real abstraction) and they required annoying MT_Vector <-> PHY_Vector conversions all over the place. No functional changes. 2013-02-21 18:30:11 +00:00

9191b783bb BGE: Some various changes to make moving the character physics type easier:
* Undoing the previous applyMovement() changes for characters. This was causing bugs for the Motion Actuator.
  * Creating a Character Motion type for the Motion Actuator with specific controls for characters. This includes moving, rotating and jumping.
  * Adding a KX_CharacterWrapper.walkDirection to set the character's direction and speed.

Note, this also resolves the following bugs:
[#33585] "Setting dLoc of motion actuator [0,0,0] via python won't stop object" reported by Manuel Bellersen (urfoex)
[#33503] "Character physics type won´t accept more than one motion anymore" reported by Mr Larodos

18f134304c BGE: Adding a jumpCount to KX_CharacterWrapper. This can be used to have different logic for a single jump versus a double jump. For example, a different animation for the second jump. 2012-12-29 10:22:19 +00:00
Mitchell Stokes
13f49f3101 BGE: Adding a maxJumps to the character controller to adjust how many jumps a character can perform before having to touch the ground. By default this is set to 1, which means a character can only jump once before having to touch the ground again. Setting this to 2 allows for double jumping. 2012-12-26 01:25:53 +00:00
Mitchell Stokes
f840bd4a9f BGE: This patch adds a character wrapper (similar to the already implemented vehicle wrapper) to control character physics options. Currently supported options are:
* jump() -- causes the character to jump
  * onGround -- specifies whether or not the character is on the ground
  * gravity -- controls the "gravity" that the character physics uses for the character

More options could be added (such as jump speed, step height, make fall speed, max slope, etc).

3bf9bb3b13 BGE: Adding support for Bullet's collision masks. Each object now has a collision mask and a collision group. Object A and object B collide if object A's groups is in object B's mask and object B's group is in object A's mask. In other words, the group defines what the object is (collision wise) and the group defines what the object can collide with.
The majority of this patch was provided by Kupoman with some edits from me and heavy testing by z0r.

244ce92dbd BGE: Setting up the RAS_ICanvas interface as the primary way to alter the OpenGL
viewport. This helps to eliminate OpenGL calls in weird places like the physics
code and to reduce glGet calls, which are expensive.

There should be no functional changes (except maybe a very slight speed improvement).

dfc19a1ff7 BGE patch #28476: Character object physics type
===============================================
This patch adds a new "Character" BGE physics type which uses Bullet's btKinematicCharacter for simulation instead of full-blown dynamics. It is appropiate for (player-controlled) characters, for which the other physics types often result unexpected results (bouncing off walls, sliding etc.) and for which simple kinematics offers much more precision.

"Character" can be chosen like any other physics type in the "Physics" section of the properties window. Current settings for tweaking are "Step Height" (to make the object automatically climb small steps if it collides with them), "Fall Speed" (the maximum speed that the object can have when falling) and "Jump Speed", which is currently not used.

See http://projects.blender.org/tracker/?func=detail&atid=127&aid=28476&group_id=9
for sample blends and a discussion on the patch: how to use it and what influences the behavior of the character object.

Known problem: there is a crash if the "compound" option is set in the physics panel of the Character object.

b5a2d7f15e Bugfix for #26795 and #26917, Fix a bug that cause the radar sensor to break
Never memset(&ob, 0,sizeof(class)) when there is a constructor, it overrides all memory.
The problem was that the memset(0) was setting the scaling to (0,0,0), the height of the cone became 'infinity' 
so GJK would iterate 'MAX_ITER' without converging due to this #NAN value

ac1b08a928 BGE patch: [#26223] Some RigidBody joints fixes (ui angles, conetwist/hinge limits etc) by Juha Mäki-Kanto + ui changes pour moi
From the tracker:::
Issues fixed:
- ConeTwist-constraint's params weren't making it to the CcdPhysicsEnvironment, also added Hinge's params.
- UI wasn't using angles where applicable.
- btHingeConstraint's constructor can create frame-matrices which don't align so the hinge doesn's start at 0 degree tilt.
This is an issue when setting limits.

Changes:
- UI: Hinge limits can be set (and disabled).
- UI: ConeTwist only has max-limits and only the twistX can be disabled
- PyApi via rna_constraint.c: added the functions limit_xyz_min, limit_xyz_max (for 6dof), limit_angle_xyz_min,
limit_angle_xyz_max (for 6dof), limit_angle_x_min, limit_angle_x_max (for hinge).
- PyApi: dropped python-function limit_cone_min. 

.:. Extra:
UI Changes:
- renamed "RigidBody Joint" to "Rigid Boidy Joint" 
- reorganized UI to conform with other parameters (e.g. Limit Rot)
- added dis/active all over the place :)

1c4150f211 BGE: ray casting works on soft body, the hit polygon is also returned. The modifications to Bullet have been reported to Bullet forum.

5b722b1e87 BGE: replace mesh works for Soft Body (including reinstantiation of physics soft body mesh).
Even a static mesh can be used as replacement: the mesh
will be instantiated with the soft body settings of the
object. The position and orientation of the soft body
is preserved after the replacement.

Known limitation: the velocity of the soft body is reset
aftet the replacement. This is because soft body don't
have a well defined velocity.

efb7dd86ff Fix for own recent reference count error.
- The armature weakref list was  being incref'd twice then decrefed twice (incref and decref were used incorrectly), now only once. My 'fix' broke this.
- In bpy_pydriver_create_dict the 2 refs added from running PyDict_SetItemString twice were undone when clearing the dictionary (added comment)
- changed Py_XDECREF to Py_DECREF int BPY_pyconstraint_update and BPY_pyconstraint_target, Py_XDECREF checs for NULL value which would have crashed blender before it got to Py_XDECREF anyway.
- after every error is reported (PyErr_Print), remove sys.last_traceback and clear the error, I found this fixed certain crashes (usually when starting the game engine or exiting blender), so best do this all the time.

- header_text.c, CcdPhysicsEnvironment.cpp, KX_CameraActuator.cpp - remove some warnings.

0b8661ab4d BGE: Occlusion culling and other performance improvements.
Added occlusion culling capability in the BGE. 
More info: http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.49/Game_Engine#BGE_Scenegraph_improvement
MSVC, scons, cmake, Makefile updated.

Other minor performance improvements:
- The rasterizer was computing the openGL model matrix of the objects too many times
- DBVT view frustrum culling was not properly culling behind the near plane:
  Large objects behind the camera were sent to the GPU
- Remove all references to mesh split/join feature as it is not yet functional
