caa8b26ce5 Fixes in TinyAudio, play sound on collision impact, can be configured in URDF/SDF file.
Requires a modified setup.py (or use premake4 to compile)

Example script:
import pybullet as p
import time
p.connect(p.GUI)
plane = p.loadURDF("plane_with_collision_audio.urdf")
box = p.loadURDF("cube.urdf",[0,0,1])
p.setGravity(0,0,-10)
while (1):
  p.stepSimulation()
  time.sleep(1./240.)

d88d0e92ef also update m_jointLowerLimit/m_jointUpperLimit in multibody link. 2020-07-07 19:49:29 -07:00
Erwin Coumans
c517c434e6 pybullet allow to enable/change joint limits:
pybullet.changeDynamicsInfo(objectUniqueId, linkIndex, jointLowerLimit=..., jointUpperLimit=...) # jointLowerLimit <= jointUpperLimit

and joint limit max force:
pybullet.changeDynamicsInfo(objectUniqueId, linkIndex, jointLimitForce=...)

For example:
p.changeDynamics(sphereUid,linkIndex, jointLowerLimit=1, jointUpperLimit=3, jointLimitForce=10.5)

add b3ChangeDynamicsInfoSetJointLimit/b3ChangeDynamicsInfoSetJointLimitForce
add getConstraintType for btMultiBodyConstraint

e6a0206d47 Allow to remove soft body anchors, using pybullet.removeConstraint (untested).
Usage example:
anchors = []
anchors.append(p.createSoftBodyAnchor(clothId  ,0,-1,-1))
anchors.append(p.createSoftBodyAnchor(clothId ,3,boxId,-1, [0.5,-0.5,0]))
for a in anchors:
  p.removeConstraint(a)

754dbd5fda add pybullet.unsupportedChangeScaling feature for some small experiments, this is not general and has many limitations that are not likely are going to be resolved,
so unless it does what you want, ignore this api, it is unsupported!

f0cccf0faa add collisionFilterMask to rayTestBatch and rayTest
This will allow to exclude (filter) certain bodies.
By default, static bodies have collision group 2, and dynamic (mass=1) bodies have collision group 1.
As long as mask & group != 0, a raytest will be performed.

daa0a27403 add reportHitNumber to allow reporting a specific ray intersection hit
(by default, pybullet.rayTestBatch reports the closest hit, so you can report 2nd closest or 3rd closest hit etc)
Fix pybullet.createCollisionShape, in some cases (concave trimesh, convex mesh) two instances were created.
