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

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.

* off by default.
* new/delete are at the bottom of each class
* python BGE objects have the new/delete in the Py_Header macro.

c8b4cf9206 2.50:
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD

Notes:
* Game and sequencer RNA, and sequencer header are now out of date
  a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
  not needed anymore.
  * Fix "duplicate strip" always increase the user count for ipo.
  * IPO pinning on sequencer strips was lost during Undo.

3511f8ef9f BGE Physics
Clamp objects min/max velocity.
Accessed with bullet physics from the advanced button with dynamic and rigid body objects.
- useful for preventing unstable physics in cases where objects move too fast.
- can add linear velocity with the motion actuator to give smooth motion transitions, without moving too fast.
- minimum velocity means objects don't stop moving.
- python scripts can adjust these values speedup or throttle velocity in the existing direction.

Also made copy properties from an object with no properties work (in case you want to clear all props)

509ca83ef1 BGE patch 18065: gameobj mass writeable + setmass actuator. This patch allows to change the mass of a dynamic or rigid body object during the game. Two methods are available: in a Python script by setting the mass attribute of the game object; by logic brick with the Edit Object->Dynamics->Set Mass actuator. The mass can only be set on dynamic objects and must be a positive floating point value. 2009-01-14 22:33:39 +00:00

00c12e0906 BGE patch: dynamically update the coumpound parent shape when parenting to a compound object.
This patch modifies the way the setParent actuator and KX_GameObject::setParent() function
works when parenting to a compound object: the collision shape of the object being parented
is dynamically added to the coumpound shape. 
Similarly, unparenting an object from a compound object will cause the child collision shape
to be dynamically removed from the parent shape provided that is was previously added with 
setParent.

Note: * This also works if the object is parented to a child of a compound object: the
        collision shape is added to the compound shape of the top parent.
      * The collision shape is added with the transformation (position, scale and orientation)
        it had at the time of the parenting.
      * The child shape is rigidly attached to the compound shape, the transformation is not
        affected by any further change in position/scale/orientation of the child object.
      * While the child shape is added to the compound shape, the child object is removed from
        the dynamic world to avoid superposition of shapes (one for the object itself and
        one for the compound child shape). This means that collision sensors on the child
        object are disabled while the child object is parent to a compound object.
      * There is no difference when setParent is used on a non-compound object: the child
        object is automatically changed to a static ghost object to avoid bad interaction
        with the parent shape; collision sensors on the child object continue to be active
        while the object is parented.
      * The child shape dynamically added to a compound shape modifies the inertia of the
        compound object but not the mass. It participates to collision detection as any other
        "static" child shape.

949b6ca80f BGE bug #17688 fixed: Near Sensor Reset not working (for Gamekit)
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

7e990de294 BGE bug fix (good for 2.47): remove static-static collision messages on the console since previous SetParent fix. The physical object is set to static+ghost while the object is parented. This behavior will be made optional in a future release. The DisableDynamics actuator will also make the object static except that the ghost/non-ghost flag is preserved. 2008-07-19 10:27:52 +00:00

a397b4b82f BGE bug fix (good for 2.47): SetParent actuator did not work on dynamic objects. Dynamics will now be disabled automatically and the object will be set ghost for the duration of the parenting; this is to avoid static interaction with the parent object. The dynamic state is restored when the parenting is removed with RemoveParent actuator. This fix also applies to setParent() and removeParent() python functions. 2008-07-18 14:40:24 +00:00

15c105c157 BGE patch: Add damping and clamping option to motion actuator.
This patch introduces two options for the motion actuator:

damping: number of frames to reach the target velocity. It takes
into account the startup velocityin the target velocity direction
and add 1/damping fraction of target velocity until the full 
velocity is reached. Works only with linear and angular velocity.
It will be extended to delta and force motion method in a future
release.

clamping: apply the force and torque as long as the target velocity
is not reached. If this option is set, the velocity specified 
in linV or angV are not applied to the object but used as target
velocity. You should also specify a force in force or torque field: 
the force will be applied as long as the velocity along the axis of
the vector set in linV or angV is not reached. Works best in low
friction environment.
