move setup.py back to eglRenderer extension, use pkgutil.get_loader('eglRenderer').get_filename()
disable dlmopen by default, unless B3_USE_DLMOPEN is defined.
just use pybullet.loadPlugin("eglRendererPlugin") before loading/creating any objects.
use end/startRendering (swap buffers) before the rendering in the eglPlugin
add grpcPlugin, it can work in GUI, SHARED_MEMORY_SERVER, DIRECT and other modes.
example script to start server from pybullet:
import pybullet as p
p.connect(p.GUI)
#if statically linked plugin
id = p.loadPlugin("grpcPlugin")
#dynamics loading the plugin
#id = p.loadPlugin("E:/develop/bullet3/bin/pybullet_grpcPlugin_vs2010_x64_debug.dll", postFix="_grpcPlugin")
#start the GRPC server at hostname, port
if (id>=0):
p.executePluginCommand(id, "localhost:1234")
Only in DIRECT mode, since there is no 'ping' you need to call to handle RCPs:
numRPC = 10
while (1):
p.executePluginCommand(id, intArgs=[numRPC])
This removes the need to specify the body id/link index when retrieving a user data entry.
Additionally, user data can now optionally be set to visual shapes as well.
The following public pybullet APIs have changed (backwards incompatible)
addUserData and getUserDataId
Makes linkIndex parameter optional (default value is -1)
Adds optional visualShapeIndex parameter (default value is -1)
getUserData and removeUserData
Removes required parameters bodyUniqueId and linkIndex
getNumUserData
Removes required bodyUniqueId parameter
getUserDataInfo
Removes required linkIndex parameter
Changes returned tuple from (userDataId, key) to (userDataId, key, bodyUniqueId, linkIndex, visualShapeIndex)
use b3RaycastBatchAddRays API to enable MAX_RAY_INTERSECTION_BATCH_SIZE_STREAMING num rays.
Old API (b3RaycastBatchAddRay) sticks to 256 rays, MAX_RAY_INTERSECTION_BATCH_SIZE.
reduce 'm_cooldownTime' from 1000 microseconds to 100 microseconds (overhead in raycast is too large)
If needed, we can expose this cooldown time.
Replace malloc by btAlignedObjectArray (going through Bullet's memory allocator)
Method def isAlive(self), which defaults to return self._alive < 0, and each environment can override this method (Half Cheetah would implement return False)
(In response to bea468fb93)
As suggested in https://github.com/bulletphysics/bullet3/pull/1759. The default isDone lets done = alive<0, and a special case is made for halfcheetah, forcing done=False.
I had to pass the 'alive' condition as an additive parameter of WalkerBaseBulletEnv.
