Use float in moto instead of double for MT_Scalar.
This switch allow future optimization like SSE.
Additionally, it changes the OpenGL calls to float versions as they are
very bad with doubles.

Fixing crash if the physic type is set sensor or character. Caused by a790e172d0281e64.
Fixing memory leak, if the constraint is deleted with Python API removeConstraint().
Add RemoveConstraint() method to avoid code duplication.
Rename old RemoveConstraint() to RemoveConstraintById() which is more suitable name for this method.

Constraint on soft bodies are special and return 0 as constraint id.
So we have to check that the id is not 0 in function setParam, getParam, getAppliedImpulse and removeConstraint.

Angular velocity clamping was missing from the BGE. It is implemented
similarly to the linear velocity clamping. It is needed to be able to
drive physical simulations of systems that have a limited rotational
speed.

This patch uses the Bullet "internal tick callback" functionality to
ensure that velocity clamping is performed after every physics update.
This makes a difference when physics subticks > 1, as in that case the
too-high velocity could have impacted the simulation.
This patch follows the examples at [1] and [2]; the latter example
also explains that the way we limit velocity in the BGE (before this
patch) is wrong.

Currently we can't update the physics mesh of an added rigid body.
The cause is that that we need to update all shapes to say that the mesh was changed, for static object we don't do that previously because we use a odd way to reallocate memory at the same place.
So now when a mesh is changed we iterate all physics controllers which use the same shape info and recreate its shape with the correct mesh.

Currently there are bugs with physics objects in inactive layers,
character and softbody.
I added a function in CcdPhysicsEnvironement to know if a physics
controller is currently active and for soft body I added the correct function in UpdateCcdPhysicsController to re-add a softbody in the dynamics world.

A Python API for the collision group / mask has been added:
```
KX_GameObject.collisionGroup
KX_GameObject.collisionMask
```
The maximum number of collision groups and masked has been increased from eight to sixteen.
This means that the max value of collisionGroup/Mask is (2 ** 16) - 1
EndObject will now activate objects that were sleeping and colliding with the removed object.
This means that, unlike now, if a rigid body starts sleeping on top of another object, when the latter is removed the rigid body will activate and fall, rather than float midair as before.
Collision groups that do not intersect used to collide on the first frame. Now this has been fixed so that they collide appropriately.
Thanks to agoose77 for his help.

Commit ffee7f1a58a18bc08add94176ddffe29809139a6 broke vehicle constraints; this fixes that.

Two areas of the BGE use a hard-coded 60 Hz as frame rate. However, this 60 Hz is just a default setting, and can be changed in the Blender interface.
This setting is now used instead of the hard-coded 60 Hz.
CcdPhysicsEnvironment::SetFixedTimeStep() is actually never called, as we don't even support a true fixed-timestep simulation.

Blender allows you to create a constraint without specifying its reference
object, even when the constraint requires such a reference. The BGE would
crash on this. This change simply ignores such a constraint.

This patch adds two parameters to the functions in the
collisionCallbacks list. The callback function should thus be like
this:
```
def on_colliding(other, point, normal):
print("Colliding with %s at %s with normal %s" % (other, point, normal))
game_ob.collisionCallbacks.append(on_colliding)
```
The `point` parameter will contain the collision point in world
coordinates on the current object, and the `normal` contains the
surface normal at the collision point.
The callback functions are checked for the number of arguments
`co_argcount`. The new `point` and `normal` arguments are only passed
when `co_argcount > 1` or when `co_argcount` cannot be determined.

Refactored some code to be easier to read. Semantically the code is
identical.
- Some conditions were negated to be able to return/continue early,
rather than having the majority of the code inside an if-body.
- Conditions were simplified (!(a == b)) turned into (a != b);
repeated conditions calculated only once.
- Unnecessary variables and one unnecessary condition were
eliminated.

The Bullet 2.82 update uses a different method for ray casting that
seems incompatible with our older files. So, for now we just force the
vehicle physics to use the older ray casting method.

refcount.
I'm not sure why this function ever increased the object's refcount. Any
place in the code that calls KX_GameObject::GetParent() has to turn
around and call parent->Release(). Forgetting to call Release() was a
common cause of memory leaks (in fact, KX_SteeringActuator was probably
leaking). If the refcount needs to be increased, the calling code can
handle calling AddRef().

The current physics conversion code was moved from
KX_ConvertPhysicsObjects to CcdPhysicsEnvironment.
|
|
* Moving the BlenderDebugDraw (derived from btIDebugDraw) from
KX_BlenderSceneConverter to CcdPhysicsEnvironment
* Moving CcdPhysicsEnvironment initialization to CcdPhysicsEnvironment
(this could probably be cleaned up some more with some sort of
factory, or at least moving code to CcdPhysicsEnvironment's
constructor)
* Simplifying physics environment initialization (went from two
switches to one)
|
|
Instead, it now relies more on our physics abstractions (e.g.,
PHY_IPhysicsEnvironment).
|
|
Use bullet's old method of doing ray casts to stay compatible with old
files. It's faster but a bit less accurate.
